palm Deira detail & video

The Palm Deira was announced for development in

October 2004. [2][8] No timetable for completion has been announced. The first announced design was 8 times larger than the Palm Jumeirah, and 5 times larger than the Palm Jebel Ali, and was intended to house one million people. Originally, the design called for a 14 km (8.7 mi) by 8.5 km (5.3 mi) island with 41 fronds. Due to a substantial change in depth in the Persian Gulf the farther out the island goes, the island was redesigned in May 2007. The project then became a 12.5 km (7.8 mi) by 7.5 km (4.7 mi)

island with 18 larger fronds. [2] It will be located alongside Deira.

By early October 2007, 20% of the island's reclamation was complete, with a total of 200 million cubic metres (7 billion cubic feet) of sand

already used. [2] Then in early April 2008, Nakheel announced that more than a quarter of the total

area of the Palm Deira had been reclaimed. [9] This amounted to 300 million cubic metres (10.6 billion

cubic feet) of sand. [9] Since the island is so large, it is being developed in several phases. The first one is

the creation of Deira Island. [2] This portion of the Palm will sit alongside the Deira Corniche between the entrance to Dubai Creek and Al Hamriya Port. Promotional materials state that Deira Island will

act as "the gateway to The Palm Deira" [10] and help

to revitalize the aging area of Deira. [11] By early April 2008, 80% of Deira Island Front's reclamation

was complete. [9]

A new redesign was quietly introduced in November

2008, further reducing the size of the project. [12]

palm island construction details and video

he Palm Islands are artificial peninsulas constructed of sand dredged from the bottom of the Persian Gulf by the Belgian company Jan De Nul and the Dutch company Van Oord. The sand is sprayed by the dredging ships, which are guided by DGPS, on to the required area in a process known as rainbowing because of the arcs in the air when the sand is sprayed. The outer edge of each Palm's encircling crescent is a large rock breakwater. The breakwater of the Palm Jumeirah has over seven million tons of rock. Each rock was placed individually by a crane, signed off by a diver and

given a GPS coordinate. [citation needed] The Jan De Nul Group started working on the Palm Jebel Ali in 2002 and had finished by the end of 2006. The reclamation project for the Palm Jebel Ali includes the creation of a four-kilometre-long peninsula, protected by a 200-metre-wide, seventeen-

kilometre long circular breakwater. 210,000,000 m 3

of rock, sand and limestone were reclaimed (partly originating from the Jebel Ali Entrance Channel dredging works). There are approximately 10,000,000 cubic metres of rocks in the slope protection works.

Main article: Palm Jumeirah

The Palm Jumeirah seen from the International Space Station.

The Palm Jumeirah ( Coordinates: 25°06′28″N

55°08′15″E ) consists of a tree trunk, a crown with 16 fronds, and a surrounding crescent island that forms an 11 kilometer-long breakwater. The island itself is 5 kilometers by 5 kilometers. It will add 78 kilometers to the Dubai coastline. The first phase of development on the Palm Jumeirah will create 4,000 residences with a combination of villas and apartments over the next 3 to 4 years.

Residents began moving into their Palm Jumeirah properties at the end of 2006, five years after land reclamation began, according to project developer Nakheel Properties. This signaled the end of phase one of construction, which includes approximately 1,400 villas on 11 of the fronds of the island and roughly 2,500 shoreline apartments in 20 buildings on the east side of the trunk.

Nakheel Properties will mark the arrival of the first residents by bringing one of the world's largest airships to Dubai. It has agreed to a deal with Airship Management Services Inc. for a 197 feet

(60 m) long, 250,000-cubic-foot (7,100 m 3 ) Skyship 600 dirigible.

According to Nakheel Properties officials, the process of adding 78 kilometers of beach is under way, while eight of the 32 hotels on The Palm Jumeirah have begun construction, including the Taj Exotica Resort and Spa, which was planned for completion in late 2008 or early 2009, is delayed and now expected to open in early 2010. The first phase Atlantis, The Palm Resort, is scheduled to be completed by December 2008. Atlantis, The Palm opened on 24 September 2008.

The "Golden Mile", the strip of land located along the center of the trunk overlooking the canal, is set for completion in the first quarter of 2008. The tenants started moving in 30 April 2009. Construction has also begun on the Palm Jumeirah Monorail, which will take three years to complete and will serve as a transit system between the Gateway Station at the trunk of The Palm Jumeirah and the Atlantis Station on the crescent. (Emirates News Agency, WAM).The Monorail opened May 6, 2009 only using Atlantis Hotel and Gateway Towers Stations

palm island - Dubai

The Palm Islands are an artificial archipelago in Dubai, United Arab Emirates on which major commercial and residential infrastructures will be constructed. They are being constructed by Nakheel Properties, a property developer in the United Arab Emirates, who hired Belgian and Dutch dredging and marine contractor Jan De Nul and Van Oord, some of the world's specialists in land reclamation. The islands are the Palm Jumeirah, the Palm Jebel Ali and the Palm Deira.

Each settlement will be in the shape of a palm tree, topped with a crescent, and will have a large number of residential, leisure and entertainment centers. The Palm Islands are located off the coast of The United Arab Emirates in the Persian Gulf and will add 520 kilometers of beaches to the cityof Dubai.

The first two islands will comprise approximately 100 million cubic meters of rock and sand. Palm Deira will be composed of approximately 1 billion cubic meters of rock and sand. All materials will be quarried in the UAE. Among the three islands there will be over 100 luxury hotels, exclusive residential beach side villas and apartments, marinas, water theme parks, restaurants, shopping malls, sports facilities and health spas.

The creation of the Palm Jumeirah began in June 2001. Shortly after, the Palm Jebel Ali was announced and reclamation work began. The Palm Deira, which is planned to have a surface area of 46.35 square kilometres, was announced for development in October 2004. Construction was originally planned to take 10–15 years, but that was before the impact of the global credit crunch hit Dubai.

Another artificial archipelagos, The World and The Universe, are placed between Palm Islands

space hotel at orbit of the earth

pprSpace tourism is space travel for recreational, leisure or business purposes. A number of startup companies have sprung up in recent years, hoping to create a space tourism industry. Orbital space tourism opportunities have been limited and expensive, with only the Russian Space Agency providing transport to date.

The publicized price for flights brokered by Space Adventures to the International Space Station aboard a Russian Soyuz spacecraft have been US$ 20–35 million, during the period 2001–2009. Some space tourists have signed contracts with third parties to conduct certain research activities while in orbit.

Russia halted orbital space tourism in 2010 due to the increase in the International Space Station crew size, using the seats for expedition crews that would be sold to paying spaceflight participants. However, tourist flights are tentatively planned to resume in 2013, when the number of single-use three-person

Soyuz launches could rise to five a year. [1][2][3][4]

As an alternative term to "tourism", some organizations such as the Commercial Spaceflight Federation use the term "personal spaceflight." Citizens in Space uses the term "citizen space

exploration." [

Top 10 tallest building in the world

Ten largest dams in the world

The following are some of the largest dams in
the world as measured by sheer volume. While
they’re not all necessarily in the “top 10″ in
terms of size, they’re certainly sights worth
visiting.
10. SRISAILAM DAM – INDIA
Image Credit: Hari_Menon
Located on the Krishna River, the Srisailam Dam
was constructed in the Nallamala Hills in a gorge
that sits approximately 300 meters above sea
level. The dam was is one of the 12 largest in
the country in terms of hydroelectric power
production but was specifically built in order to
provide irrigation for the districts of Kurnool and
Cuddapah – both of which are prone to severe
droughts.
9. NAGARJUNA SAGAR – INDIA
Image Credit:.krish.Tipirneni.
The Nagarjuna Sagar Dam can be found in the
Nalgonda district of Andhra Pradesh in India.
Considered one of the largest ever built in Asia,
this dam was completed in 1966 and features
26 individual crest gates. As far as construction
is concerned, this dam is the tallest in the world
to be made strictly from masonry and its
creation resulted in the third largest man-made
lake on the globe. The dam and its canals are
incredibly important to the ability to irrigate
nearby land.
8. VERZASCA DAM – SWITZERLAND
Image Credit: Sint Smeding
The Verzasca Dam, also known as the Contra
dam, was built between 1960 and 1965 in Val
Verzasca, Switzerland. The dam was built by
Verzasca SA, a company that generates
electricity on the site and will continue to do so
until at least 2046. The Lago di Vogorno
reservoir is artificial, created by the dam itself,
and has been responsible for causing
earthquakes during times when it is filled.
7. ATATURK DAM – TURKEY
Image Credit: Kel Patolog
Completed in 1990, the Ataturk Dam in Turkey is
a rock-fill dam found on the Euphrates River.
Originally named the Karababa Dam, the site
was later renamed in order to honor the founder
of the Turkish Republic, Mustafa Kemal Ataturk.
The dam is responsible for irrigating the regions
plains as well as for generating electricity.
6. MANGLA DAM – PAKISTAN

[Youtube:http://www.youtube.com/watch?
v=6yXbJ3NYrAU]

The twelfth largest dam in the world was built in
1967 and was funded in part by the World Bank.
The Mangla Dam came into creation thanks to
the 1960 signing of the Indus Waters Treaty in
which rights to the waters contained in the Ravi,
Beas, and Suglej rivers were given to Pakistan.
Before the dam was built Pakistan’s irrigation
system relied solely on the flow of the Indus
River – most of which was completely
unregulated.
5. TARBELA – PAKISTAN

[Youtube:http://www.youtube.com/watch?
v=ysyL-gQKOOg]

Completed back in 1976, the Tarbela Dam, also
known as Torabela or Pashto, is considered to
be the largest dam ever constructed on
Pakistan’s Indus River. While it’s not the largest
dam in the world overall, it is the largest dam
filled naturally by the earth. The dam stores
water in order to not only control flooding but
for use in irrigation and the production of hydro-
electric energy as well.
4. FORT PECK – UNITED STATES
Image Credit: Jvstin
The Fort Peck Dam in northeast Montana is one
of six dams found on the Missouri River.
Construction of this dam began in 1933 as part
of the New Deal put forth by President Franklin
D. Roosevelt and enabled over 11,000 workers
to have gainful employment during the course
of construction. The dam, which is solely
responsible for the formation of Fort Peck Lake,
is used to control flooding and generate power.
3. ASWAN DAM – EGYPT
Image Credit: upyernoz
The Aswan Dam is actually a pair of dams – the
Aswan High Dam and the Aswan Low Dam. In
ancient times it was known that the River Nile
would flood each summer as the waters flowed
down from East Africa. As the population along
the river grew it became necessary to find a way
to control flooding in this area. Now the land is
still fertile enough for farming and the people no
longer have to worry about drought but the
fields aren’t in danger of being wiped out due to
flooding, either.
2. SYNCRUDE TAILINGS – CANADA
Located near Fort McMurray in Alberta, Canada,
the Syncrude Tailings Dam is approximately
540,000,000 meters in volume. The dam is
currently maintained by a company known as
Syncrude Canada Ltd – a company responsible
for oil extraction in the Athabasca Oil Sands. The
dam serves as a barrage used to store tailings –
or leftover slimes and residues – that appear as
byproducts of the oil extraction operation.
1. THREE GORGES – CHINA
Image Credit: jasmin0916
The Three Gorges Dam in China is projected to
be the absolute largest in the world. Expected to
hold over 39,300,000,000 in volume, the
reservoir is complete but the actual dam itself
will not be completed until later this year. The
construction of this dam had a huge impact on
life in Sandouping, resulting not only in the
relocation of dozens of villages but in the
scenery as well. Because of the height of the
Three Gorges Dam the mountains now look a bit
lower than they actually are.
These dams are not only amongst the largest,
but are considered some of the most functional,
beautiful, and aesthetically pleasing in the world.
Don’t hesitate to visit one if you’re ever in the
area. Seeing one of the enormous dams in
person will prove to be an absolutely
breathtaking experience.

Evidence for alien can built giza pyramids

The pyramid is highlighted in red, and its
two diagonals are extended beyond the end
of the pyramid to the north-east and north-
west.  The mass of squiggly lines above the
pyramid is the Delta of the Nile River, and,
as you can see the two diagonals encase the
Nile neatly and entirely. IS THAT A
COINCIDENCE???
Yes,  I'm sure that the way the Egyptians did
this was to have someone walk hundreds of
miles to the end of the delta and hold a
really, really long piece of string while
someone walked all the way back to the site
of the pyramid.  Then,  those two people
stood there while two more people repeated
the process on the other side of the Pyramid.
Just so that they could build a big building in
such a way that its diagonals lie on those two
lines.
NOW THAT IS LIKELY????
Here is what really happened: A couple of
aliens, flying high enough over the earth to
be able to see where the Nile Delta's origin
is, easily saw what orientation the pyramid
would need to be in order to have its
diagonals  lie on those two lines.
Second piece of evidence:
The big dark shape on the upper left of this
diagram is the great pyramid.  If you look at
the compass rose in the bottom right, you can
see that the pyramid is lined up exactly with
the magnetic North Pole,  a difference of
only 16 minutes, or some absurdly small
number like that (there are 60 minutes in
one degree).  COINCIDENCE?   How could the
Egyptians possibly have built their pyramid
facing the exact magnetic North Pole without
even having a compass?  FYI, a compass was
not invented for a few thousand years after
the ancient Egyptians were long gone? IS
THAT LIKELY????
This is how it really worked: Those aliens,
abundant in their knowledge and drowning
in technology, came along and using their
compasses,  they landed on earth and found
the actual magnetic north and south poles.
THEN THEY BUILT THE PYRAMIDS!
Now look at this:
This is a photograph of the Great Pyramid of
Giza, and its neighbor, as seen from the
Sphinx, on the evening of the summer
solstice.  As you can see,  the sun is setting in
the exact center of the two pyramids.
COINCIDENCE???
For the Egyptians to be able to do this, they
must have known the day of the summer
solstice, and they therefore,  must have
known the exact length of the year, or
365.25;  once again, a fact not discovered
until long after the Egyptians were gone.
HOW LIKELY IS THAT???
The real story goes like this:   Those
meddling aliens, in all of their infinite
wisdom, saw the earth upon entering the
solar system, and by calculating the size of its
revolutions around the sun,  the velocity it
was at which it traveled and the angle of its
axis of rotation,  they were able to easily
calculate the longest day of the year or the
length of the year.
THEN BUILT THE PYRAMIDS!
Here is another photo:
This is a photograph taken on the day of the
winter solstice from the entrance of the
Great Pyramid.  The Big shape silhouetted in
the middle of the photograph is the Sphinx.
Since this is only a photograph, and not a
movie,  you can't get the full effect.   But
even in the photo, you can see that the sun is
tracing around the Sphinx's head.  In
actuality,  the sun rises exactly at the left side
of the base of the Sphinx's head.   Then it
traces it all the way around until it sets on
the right side of the Sphinx's head.
COINCIDENCE???
Had the Egyptians done this,   since this
occurs only on the day of the winter solstice,
they would have had to have known the
exact length of a year.
IS THAT LIKELY???
It's those aliens,  who after finding the length
of the year,  found the shortest day of the
year, and then built their Sphinx and
Pyramid accordingly.
Consider this:
This above image is a diagram of the stars of
the Belt of Orion.  Now look at the diagram
of the pyramids below.
Though this fact is not as remarkable, the
positioning of the three Pyramids of Giza are
exactly aligned with the position of the three
stars in the belt of Orion, both in position
and in size. While it is possible,  it would
create many difficulties for the Egyptians in
terms of measuring huge distances. Not only
this,  but in fact,  at the time that the
pyramids were supposedly built (about 3000
BC), the stars that make up the Belt of Orion
were not exactly at the correct angle to
match up with the pyramids.   If the location
of the stars is traced back over thousands of
years,  the time at which the belt is exactly
aligned with the pyramids is in fact 10,500
BC.  A time when there were supposedly no
civilized   humans living on the earth.
Another fact to support this is, if you
consider the Sphinx,  a lion with a human
head and then look at the size of the body,
you can see that the body is perfectly
proportioned for the head of a lion,  not the
human head.   This human head  looks tiny
and silly sitting on top of the body. This is
because the Sphinx was actually built in
10,500 BC,  around the same time as the
pyramids,  with a real head of a lion.
Evidence to support this is that there are
signs of water erosion all over the Sphinx.
The last time that there was any water
nearby, aside from the Nile is around 10,000
BC.  Also,  the constellation of Leo the Lion
(thus closely related to the Sphinx), was in
fact rising directly behind the sun in 10,500
BC.
Are they saying that the Egyptians built their
pyramids to be in the exact shape of Orion's
Belt, but purposely aligned them differently
from what was actually in the sky?  That
after they built the Sphinx, they purposely
made the head look small and funny?  Then,
they broke their backs carrying water from
the Nile just so that they could put water
erosion lines all over the body?????
In fact,  no Egyptian did it at all.  The aliens,
with their plethora of wisdom,  came down
in the year 10,500 BC and built the Pyramids
and the Sphinx.  They built it with a head of
a lion to match the Belt of Orion, as well as
the constellation of Leo.  Thousands of years
later, Ramses, the egomaniacal dictator-
pharaoh of Egypt,  decided that he didn't like
having the head of a lion on top of the statue
in his land. So,  he had a head in his own
likeness constructed instead.  But the
Egyptians, not being very skilled at huge
masonry, built the head somewhat too small.
Why is it that the great Pyramids of Giza,
built in 3,000, are perfect, and still standing
as tall as the day they were built? (Aside
from the capstone and the polished stones,
which were stripped by humans in the
building of Cairo)  The other Pyramids,
which were supposedly built about 500 years
later, all have shoddy masonry, and are
crumbling down.  An example of this is the
famous 'bent' pyramid,  which  started out
with the sides being built at one angle,  then
suddenly shifts in the middle to a shallower
angle.  This is because the angle at which it
was started  was much too steep for it to
stand when finished.   It is because the
Egyptian pharaohs saw the great pyramids
standing on their land and decided that they
wanted pyramids of their own.  But they
found that it was much harder to do than
was expected and ended up building silly
looking structures that don't even come close
to comparing with the magnitude of
elegance emanating from the great
pyramids.
Other startling evidence:
If you take the perimeter of the pyramid and
divide it by two times the height,  you get a
number that is exactly equivalent to the
number pi (3.14159...) up to the fifteenth
digit.  The chances of this phenomenon
happening by sheer chance is remarkably
small.  Did the ancient Egyptians know what
the number pi was?  Not likely,  seeing as it
was a number not calculated accurately to
the fourth digit until the 6th century, and
the pyramids calculate it to the fifteenth.
What about the fact that even though the
sides of the base of the pyramid are some
757 feet long, it still forms an almost perfect
square?  Every angle in the base is exactly
90 degrees.   In fact,  the sides have a
difference in length of something like two
centimeters, which is an incredibly small
amount.
What about the fact that although the
Egyptians kept very careful records about
everything they ever did;  every king they
had, every war they fought,  and every
structure they built, there were no records of
them ever having built the pyramids?
What about the fact that the Egyptians had
not even invented the wheel yet,  but the
blocks that they had to carry to build the
pyramids weighed about 2 tons each? 4,000
lbs.? What did they do... use cement?   In
fact, they used so much stone, that if you took
all of the stone they used and cut it into 1
foot square blocks, it would extend 2/3 of the
way around the earth!!!
If you take the line of longitude that the
pyramid lies on and the latitude that the
pyramid lies on,  31 degrees north by 31
degrees west (the fact that they are the same
number is a coincidence???) they are the
two lines that cover the most combined land
area in the world. In essence, the pyramid is
the center of all of the land mass of the
whole earth!!!!
How about the fact that a group of modern
scientists  attempted to build a pyramid out
next to the real one using modern
technologies, and after something like 100
days, succeeded in building one about 1/40
of the size of the real one????
Did you know that the height of the pyramid
(481 feet) is almost exactly 1/1,000,000,000
of the distance from the earth to the sun
(480.6 billion feet)?
What about all of that fungi that was found
in King Tutu's chamber?   Fungi which has
never before been seen on earth?  What
about the Pharaoh's curse????? You decide,
who built the Pyramids?????




Wembley stadium

Wembley Stadium (often referred to simply as
Wembley , pronounced /ˈwɛmbli/ , or
sometimes as the New Wembley ) is a football
stadium located in Wembley Park , in the
Borough of Brent, London , England . It opened
in 2007 and was built on the site of the previous
1923 Wembley Stadium . The earlier Wembley
stadium, originally called the Empire Stadium,
was often referred to as "The Twin Towers" and
was one of the world's most famous football
stadiums until its demolition in 2003. [5]
It is a UEFA category four stadium . The 90,000-
capacity venue (105,000 combined seating and
standing) is the second largest stadium in
Europe, and serves as England's national
stadium . It is the home venue of the England
national football team , and hosts the latter
stages of the top level domestic club cup
competition, the FA Cup . It is owned by English
football 's governing body, The Football
Association (The FA), through their subsidiary
Wembley National Stadium Ltd (WNSL).
Designed by Foster and Partners and Populous
(then HOK Sport), it includes a partially
retractable roof. A signature feature of the
stadium, following on from the old Wembley's
distinctive Twin Towers, is the 134 metres
(440 ft) high Wembley Arch. With a span of 317
metres (1,040 ft), this steel arch is the longest
single span roof structure in the world and,
uniquely for a stadium, requires beacons for low
flying aircraft. The stadium was built by
Australian firm Multiplex at a cost of
£798 million. The old Wembley closed in
October 2000, with demolition originally
intended for that December and the new
stadium due to open in 2003. After delays to
the project, with demolition first started in
September 2002, the old Wembley was not
completely demolished until February 2003,
with the new stadium scheduled to open in time
for the 2006 FA Cup Final . After further delays,
the stadium was delivered nearly a year late,
leading to legal disputes between WNSL and
Multiplex, who ultimately made a significant loss
on the project. The stadium was handed over
on 9 March 2007, in time to host the 2007 FA
Cup Final .
In international football, the stadium was a
central component of the failed English 2018
and 2022 FIFA World Cup bids . In 2012 it will
host the football finals of the London Olympics .
In club football, in addition to the FA Cup the
stadium also hosts the showpiece season
opening game the FA Community Shield match,
played in August between the winners of the FA
Cup and the top-level Premier League . In mid-
season it also hosts the finals of the Football
League Cup and Football League Trophy . At the
end of the domestic season the stadium also
hosts the finals of the Football League play-offs .
In European football, it hosted the 2011
Champions League Final , and will host the final
again in 2013 . In friendly tournaments, since
2009 it has been the venue of the summer
Wembley Cup. Outside of football, the stadium
also hosts major rugby league games, such as
the Challenge Cup and International Rugby
League. The stadium is also an annual regular
season venue for the American National Football
League's International Series , the first such
venue outside North America. Non-sporting
uses include large music concerts such as
Concert for Diana , Live Earth and the
Summertime Ball.
Stadium
Wembley Stadium exterior
Wembley was designed by architects Foster +
Partners and Populous (known as HOK Sport at
the time of the design phase and construction)
and with engineers Mott MacDonald , built by
Australian company Brookfield Multiplex and
funded by Sport England , WNSL (Wembley
National Stadium Limited), the Football
Association , the Department for Culture Media
and Sport and the London Development Agency .
It is one of the most expensive stadiums ever
built at a cost of £798 million (After New
Meadowlands Stadium )[6][7] and has the
largest roof-covered seating capacity in the
world. Nathaniel Lichfield and Partners was
appointed to assist Wembley National Stadium
Limited in preparing the scheme for a new
stadium and to obtain planning and listed
building permission for the development. [8]
Wembley Stadium interior
The all-seater stadium is based around a bowl
design with a capacity of 90,000, protected
from the elements by a sliding roof that does
not completely enclose it. It can also be adapted
as an athletic stadium by erecting a temporary
platform over the lowest tier of seating. [9] The
stadium's signature feature is a circular section
lattice arch of 7 m (23 ft) internal diameter with
a 315 m (1,033 ft) span, erected some 22° off
true, and rising to 133 m (436 ft). It supports all
the weight of the north roof and 60% of the
weight of the retractable roof on the southern
side. [10] The archway is the world's longest
unsupported roof structure. [11] Instead of the
39 steps climbed, in the original stadium, to
enter the Royal Box and collect a trophy, there
are now 107. [12]
A "platform system" has been designed to
convert the stadium for athletics use, but its use
would decrease the stadium's capacity to
approximately 60,000. [13] No athletics events
( track and field ) have taken place at the stadium,
and none are scheduled. [ citation needed ] The
conversion for athletics use was a condition of
part of the lottery funding the stadium received,
but to convert it would take weeks of work and
cost millions of pounds. [14]
Construction
The stadium in its very early stages of
construction c. August 2003
The initial plan for the reconstruction of
Wembley was for demolition to begin before
Christmas 2000, and for the new stadium to be
completed some time during 2003, but this
work was delayed by a succession of financial
and legal difficulties. In 2004, the London Mayor
and Brent Council also announced wider plans
for the regeneration of Wembley , taking in the
arena and the surrounding areas as well as the
stadium, to be implemented over two or three
decades.
Delays to the construction project started as far
back as 2003. In December 2003, the
constructors of the arch, subcontractors
Cleveland Bridge, warned Multiplex about rising
costs and a delay on the steel job of almost a
year due to Multiplex design changes which
Multiplex rejected. Cleveland Bridge withdrew
from the project and replaced by Dutch firm
Hollandia with all the attendant problems of
starting over. 2004 also saw errors, most
notably a fatal accident involving carpenter
Patrick O'Sullivan for which construction firm PC
Harrington Contractors were fined £150,000 in
relation to breaches of health and safety laws.
[15]
In October 2005, Sports Minister Richard
Caborn announced: "They say the Cup Final will
be there, barring six feet of snow or something
like that". By November 2005, WNSL were still
hopeful of a handover date of 31 March, in time
for the cup final on 13 May. However in
December 2005, the builders admitted that
there was a "material risk" that the stadium
might not be ready in time for the final. [16][17]
In February 2006 these worries were confirmed,
with the FA moving the game to Cardiff 's
Millennium Stadium .
Construction of the new Wembley, looking
east, taken January 2006
On 20 March 2006, a steel rafter in the roof of
the new development fell by a foot and a half,
forcing 3,000 workers to evacuate the stadium
and raising further doubts over the completion
date which was already behind schedule. [18]
On 23 March 2006, sewers beneath the stadium
buckled due to ground movement. [19] GMB
Union leader Steve Kelly said that the problem
had been caused by the pipes not being properly
laid, and that the repair would take months.
Rumours circulated that the reason for the
blockage was due to Multiplex failing to pay the
contractors who laid the pipes who then filled in
the pipes with concrete. A spokesman for
developers Multiplex said that they did not
believe this would "have any impact on the
completion of the stadium", which was then
scheduled to be completed on 31 March 2006.
On 30 March 2006, the developers announced
that Wembley Stadium would not be ready until
2007. [20] All competitions and concerts
planned were to be moved to suitable locations.
On 19 June 2006 it was announced that the turf
had been laid. On 19 October 2006 it was
announced that the venue was now set to open
in early 2007 after the dispute between The
Football Association and Multiplex had finally
been settled. WNSL was expected to pay around
£36m to Multiplex, on top of the amount of the
original fixed-price contract. The total cost of
the project (including local transport
infrastructure redevelopment and the cost of
financing) was estimated to be £1 billion
(roughly US$1.97 billion).
Handover and opening
The Bobby Moore Sculpture stands outside
the stadium entrance, looking down
Wembley Way
The new stadium was completed and handed
over to the FA on 9 March 2007. The official
Wembley Stadium website had announced that
the stadium would be open for public viewing
for local residents of Brent on 3 March 2007,
however this was delayed by two weeks and
instead happened on 17 March.
While the stadium had hosted football matches
since the handover in March, the stadium was
officially opened on Saturday 19 May, with the
staging of the 2007 FA Cup Final . Eight days
before that on Friday 11 May, the Bobby Moore
Sculpture had been unveiled by Sir Bobby
Charlton outside the stadium entrance, as the
"finishing touch" to the completion of the
stadium. The twice life-size bronze statue,
sculpted by Philip Jackson , depicts England's
1966 World Cup winning captain Bobby Moore,
looking down Olympic Way . [21][22][23]
Structure
The stadium contains 2,618 toilets, more
than any other venue in the world. [24]
The stadium has a circumference of 1 km
(0.62 mi). [25]
The bowl volume is listed at 1,139,100 m 3 ,
somewhat smaller than the Millennium
Stadium in Cardiff, but with a greater seating
capacity. [26]
At its peak, there were more than 3,500
construction workers on site. [27]
4,000 separate piles form the foundations
of the new stadium, [25] the deepest of
which is 35 m (115 ft). [25]
There are 56 km (35 mi) of heavy-duty
power cables in the stadium. [25]
90,000 m 3 (120,000 yd 3 ) of concrete and
23,000 tonnes (25,000 short tons) of steel
were used in the construction of the new
stadium. [25]
The total length of the escalators is 400 m
(¼ mi). [25]
The Wembley Arch has a cross-sectional
diameter greater than that of a cross-
channel Eurostar train . [28][29]
Pitch
Aerial of the Wembley Stadium pitch
The new pitch is 13 ft (4.0 m) lower than the
previous pitch. The pitch size, as lined for
association football, is 115 yd (105 m) long by
75 yd (69 m) wide, slightly narrower than the
old Wembley, as required by the UEFA stadium
categories for a category four stadium, the top
category.
Since the completion of the new Wembley, the
pitch has come into disrepute since it was
described as being "no good" and "not in the
condition that Wembley used to be known for"
by Slaven Bilić before the game between
England and the team he managed, Croatia . [30]
It was confirmed when the pitch was terribly cut
up during the game, which was blamed by some
[31] as the reason England did not qualify for
UEFA Euro 2008 . [32] The Football Association
admitted in April 2009 after the FA Cup semi-
finals that improvements are needed to the
Wembley pitch after criticism of the surface by
Sir Alex Ferguson, Arsène Wenger and David
Moyes . The grass has been relaid ten times since
the stadium re-opened in 2007 and was relaid
again in the summer of 2009, ahead of the
2009 Community Shield. [33][34]
In March 2010, the surface was relaid for the
10th time since 2007, when the stadium was
built. In April 2010, the pitch was again
criticised following the FA Cup semi-finals ,
during which the players found it difficult to
keep their footing and the surface cut up despite
the dry conditions. Tottenham Hotspur boss
Harry Redknapp labelled it a "disgrace" after his
side's semi-final defeat to Portsmouth. [35]
After the 2010 FA Cup Final , Chelsea captain
John Terry said, "The pitch ruined the final. It’s
probably the worst pitch we’ve played on all
year. It was not good enough for a Wembley
pitch." [36] It was relaid with Desso semi-
artificial pitch, ahead of the 2010 community
shield game between Chelsea and Manchester
United . Michael Owen , who previously criticized
the pitch for causing him injury, said that it was
much improved. [37]
Covering
Close-Up of the Arch
The stadium roof has an area of 40,000 m 2 , of
which 13,722 m 2 is movable. [26] The primary
reason for the sliding roof was to avoid shading
the pitch, as grass demands direct sunlight to
grow effectively. [38] The sliding roof design
minimises the shadow by having the roof pulled
back on the east, west and south. [39] Angus
Campbell, chief architect, also said that an aim
was for the pitch to be in sunlight during the
match between the beginning of May and the
end of June, between 3pm and 5pm, which is
when the FA and World cups would be played.
However it was mentioned during live
commentary of the FA Cup Final in 2007 that
the pitch was in partial shade at the start at 3
pm and also during the match. [40]
The stadium roof rises to 52 metres above the
pitch and is supported by an arch rising 133
metres above the level of the external
concourse. With a span of 315 metres, the arch
is the longest single span roof structure in the
world. [25]
Litigation
The Australian firm Multiplex, which was the
main contractor on Wembley Stadium, made
significant losses on the project. [41][42] In an
attempt to recoup some of those losses, the
firm has initiated a number of legal cases
against its sub-contractors and consultants. [43]
The largest of these - the largest legal claim in
UK legal history - is a claim for £253 million
against the structural engineering consultants
Mott Macdonald . [44] In preliminary hearings
the two architecture practices which worked for
Multiplex on the project have been ordered to
allow Multiplex access to their records in order
for them to build a case. The practices, Foster +
Partners and Populous , estimate the costs of
providing access and answering Multiplex's
queries at £5 million. [45] The case is not due to
be heard until January 2011. [46] Mott
Macdonald has issued a counter-claim for
unpaid fees of £250,000. [44]
Multiplex has also taken the original steel
contractor, Cleveland Bridge, to court in order to
claim up to £38 million [47] compensation for
costs resulting from Cleveland Bridge walking
away from the job. Cleveland Bridge, in turn,
claimed up to £15 million from Multiplex. The
case was finally resolved in September 2008
with Cleveland Bridge ordered to pay
£6.1 million in damages and 20% of Multiplex's
costs after the court found Cleveland Bridge was
in the wrong to walk off site. The judge criticised
both sides for allowing the case to reach court,
pointing out that total costs were £22 million,
including £1 million for photocopying. [48]
Multiplex's ultimate bill is estimated to be over
£10 million.
Multiplex is also contesting a claim from its
concrete contractor, PC Harrington, that
Multiplex owes £13.4 million to PC Harrington.
[49]
The dispute between Multiplex (now known as
Brookfield) and Mott Macdonald was settled out
of court in June 2010, the judge having warned
that costs were likely to be more than
£74 million. [50]
Tenants
Wembley Stadium during the 2007 Race of
Champions
The English national football team is a major
user of Wembley Stadium. Given the ownership
by The Football Association as of 10 March
2007, the League Cup final moved back to
Wembley from Cardiff following the FA Cup final
and FA Community Shield . Other showpiece
football matches that were previously staged at
Wembley, such as the Football League
promotion play-offs and the Football League
Trophy final, have returned to the stadium, as
has the Football Conference play-off final.
Additionally, the Rugby League Challenge Cup
final returned to Wembley Stadium in 2007. The
new Wembley is a significant part of the plan for
the 2012 Summer Olympics in London; the
stadium will be the site of several games in both
the men's and women's football tournaments,
with the finals planned to be held there. [51]
Additionally, Wembley is one of the 12 2015
Rugby World Cup venues, for which pitch
changes will have to be made.
The Race of Champions staged their 2007 and
2008 events at the stadium.
Wembley has had a long association with
American Football . A USFL game was staged
there in 1984, and between 1986 and 1993 the
old Wembley stadium hosted eight NFL
exhibition games featuring 13 different NFL
teams. [52] Since the new Wembley Stadium
opened in 2007 Wembley has hosted games
during the NFL regular season. As a result of
this, NFL commissioner Roger Goodell stated in
October 2009 that "he expects the NFL will start
playing multiple regular-season games in Britain
in the next few years, an expansion that could
lead to putting a franchise in London." [53] In
2012, the league announced that the St. Louis
Rams would become a permanent tenant of
Wembley Stadium, playing an annual game at
the stadium every year from 2012 to 2014; part
of the reason the Rams were chosen was the
fact that the team is owned by Stan Kroenke ,
who also is majority shareholder in a local
Premier League team, Arsenal .
Music
The stage at the Live Earth concert held at
Wembley on 7 July 2007.
Besides football, Wembley can be configured to
hold many other events, particularly major
concerts.
The first concert at the new stadium was given
by George Michael on 9 June 2007. [54] Bon Jovi
were scheduled to be the first artists to perform
at the new Wembley but the late completion of
the stadium saw the concerts relocated to the
National Bowl and the KC Stadium .
Muse became the first band to sell out the new
stadium on 16 and 17 June 2007, and released
a live DVD of the performance.
Other acts to have performed at the stadium are
Metallica, Foo Fighters, Madonna, Coldplay ,
Oasis , Take That and AC/DC . [55]
Wembley stadium hosted Take That Present:
The Circus Live for 4 nights in summer 2009.
The tour became the fastest selling tour in UK in
history [56] before that record was broken by
Take That two years later with their Progress
Live tour.
Two large charity concerts have been held at the
new Wembley stadium, the Concert for Diana , a
memorial concert to commemorate ten years
after the Death of Princess Diana , and Live
Earth, a concert hosted at Wembley as part of
the Live Earth Foundation, committed to
combating climate change .
Take That concert
95.8 Capital FM 's Summertime Ball, which was
previously hosted with 55,000 spectators at the
Arsenal Emirates Stadium and slightly less in
Hyde Park (as Party in the Park ), was hosted at
Wembley Stadium on 6 June 2010, and was
headlined by Rihanna and Usher . The move to
Wembley allowed many more fans to watch the
annual music event which has previously lasted
over 5 hours with more than 15 performers. It
is thought to be the biggest commercial music
event held at the stadium. It will return to the
Stadium in 2011, with an even larger concert.
American punk rock band Green Day continued
their world tour, playing at Wembley on 19 June
2010. The gig was Green Day's biggest audience
yet. [57]
Muse returned to Wembley Stadium on 10 and
11 September 2010 as part of their Resistance
Tour to a sell-out crowd, having previously
played there in June 2007.
Madonna played Wembley in 2008 during her
Sticky and Sweet Tour , to a sold-out audience of
74,000. The event has surpassed all gross
revenue for a single concert at Wembley,
grossing nearly $12 million USD.

The Chennai Metro (Tamil:
is a rapid transit
system in Chennai, Tamil Nadu , India. The Phase
I of the project consisting of two corridors
covering a length of 45.1 km is under
construction. The elevated section of the project
is scheduled to be operational by 2013 and the
entire project is scheduled to be completed by
the financial year 2014-2015. About 55% of the
corridors in Phase I is underground and the
remaining is elevated.
Background
This unreferenced section requires
citations to ensure verifiability .
Chennai is the 4th largest metropolitan city in
India. Chennai, often known as the Detroit of
Asia , is widely known for its presence in the
automotive industry and has attracted several
global automakers to set up their factories in the
city becoming one of the global leaders in the
industry. Apart from automobiles, it also has
development centres set up by many software
companies which contributed 14% of India's
total software exports of
144,214 crore ( US$ 28.77 billion) during
2006–07, making it the second-largest exporter
of software in the country, behind Bangalore.
Based on all these industrial and technological
advancements, urban population has risen
rapidly, requiring need for faster and safer
transportation at all times. The city already has
multiple modes of transportation. A bus system
is run by the Chennai MTC and is augmented by
the Chennai suburban railway network run by
the Southern Railway . In addition to this, the
Chennai Corporation has also implemented the
Chennai MRTS project; an elevated railway
system was sanctioned in 1984 to ease
congestion in central Chennai. However, traffic
congestion was still a big problem for both the
citizens as well as the City's governing body.
Hence, the Chennai Corporation has decided to
implement the Chennai Metro project which will
be another alternate transportation mode to a
metropolis like Chennai. Mr K.Rajaraman IAS,
1989 Batch Officer of Tamil Nadu cadre is the
Managing Director of CMRL.
History
After the success of the Delhi metro , a similar
system was mooted for the city of Chennai by E.
Sreedharan of the DMRC to the then Chief
Minister of Tamil Nadu Karunanidhi .[3] The plan
was later dropped in favour of a highly
ambitious monorail network, spread over the
whole city during Jayalalitha 's tenure.
[4] Karunanidhi revived the metro rail project to
life once again by including it in the 2007-08
State Government's budget, and an amount of
50 crores had been sanctioned for preliminary
works which included a Detailed Project Report
(DPR) to be prepared by the DMRC Rail
Project . The approval for the project was
finally given by the state cabinet on 7 November
2007 [5] and is to be executed by a Special
purpose vehicle, the Chennai Metro Rail Limited
(CMRL).

Other Proposals
Several studies and proposals have been made
to identify new lines to augment the two lines
under construction.
Two corridors have been proposed in the
comprehensive transportation study submitted
by Wilbur Smith Associates [7] from
Medavakkam to St. Thomas Mount and
Madhavaram to Lighthouse via Radhakrishnan
Salai.
A metro line from Thiruvanmiyur to
Kottivakkam and beyond via ECR has been
proposed by CMRL in the steering committee
meeting of the department of Highways and
Minor Ports. But it has been decided to defer it
for present and take it up later. This was
proposed as an alternate for the East Coast
Elevated Expressway [8]
A project study was taken up to establish links
between Moolakadai-- Thirumangalam ,
Moolakadai-- Thiruvanmiyur and Luz—
Poonamallee through Iyyappanthangal. [9]
Apart from these, there are demands to extend
the Metro Rail to Tambaram.[10] State
Government is considering extension to
Tambaram. [11]
Proposed MRTS take-over by CMRL
The MRTS , operated by Southern Railway , is
proposed to be taken over by the CMRL thereby
bringing all the elevated tracks and underground
tracks inside the city under one organization.
The Chennai MRTS is a very poorly executed
project and is a loss making enterprise at
present. After the merger, it is proposed to
replace the current EMUs in the MRTS with air-
conditioned coaches with automatic doors.

Taipei 101

Taipei 101 ( Chinese: 台北101 / 臺北101),
formerly known as the Taipei World Financial
Center , is a landmark skyscraper located in
Xinyi District , Taipei, Republic of China (Taiwan ).
The building ranked officially as the world's
tallest from 2004 until the opening of the Burj
Khalifa in Dubai in 2010. In July 2011, the
building was awarded LEED Platinum
certification, the highest award in the
Leadership in Energy and Environmental Design
(LEED) rating system and became the tallest and
largest green building in the world. [3] Taipei
101 was designed by C.Y. Lee & partners and
constructed primarily by KTRT Joint Venture and
Samsung C&T . The tower has served as an icon
of modern Taiwan ever since its opening, and
received the 2004 Emporis Skyscraper Award .
[4] Fireworks launched from Taipei 101 feature
prominently in international New Year's Eve
broadcasts and the structure appears frequently
in travel literature and international media.
Taipei 101 comprises 101 floors above ground
and 5 floors underground. The building was
architecturally created as a symbol of the
evolution of technology and Asian tradition (see
Symbolism ). Its postmodernist approach to
style incorporates traditional design elements
and gives them modern treatments. The tower
is designed to withstand typhoons and
earthquakes. A multi-level shopping mall
adjoining the tower houses hundreds of
fashionable stores, restaurants and clubs.
Taipei 101 is owned by the Taipei Financial
Center Corporation (TFCC) and managed by the
International division of Urban Retail Properties
Corporation based in Chicago. The name
originally planned for the building, Taipei World
Financial Center , until 2003, was derived from
the name of the owner. The original name in
Chinese was literally, Taipei International
Financial Center

Burj Khalifa ( Arabic : " Khalifa
Tower"), [8] known as Burj Dubai prior to its
inauguration, is a skyscraper in Dubai, United
Arab Emirates, and is the tallest manmade
structure in the world , at 829.84 m (2,723 ft).
[3][8] Construction began on 21 September
2004, with the exterior of the structure
completed on 1 October 2009. The building
officially opened on 4 January 2010, [1][9] and
is part of the new 2 km 2 (490-acre) flagship
development called Downtown Dubai at the
'First Interchange' along Sheikh Zayed Road ,
near Dubai's main business district. The tower's
architecture and engineering were performed
by Skidmore, Owings and Merrill of Chicago ,
with Adrian Smith as chief architect, and Bill
Baker as chief structural engineer. [10][11] The
primary contractor was Samsung C&T of South
Korea .[12]
The total cost for the project was about US
$1.5 billion; and for the entire "Downtown
Dubai" development, US$20 billion. [13] In
March 2009, Mohamed Ali Alabbar , chairman of
the project's developer, Emaar Properties, said
office space pricing at Burj Khalifa reached US
$4,000 per sq ft (over US$43,000 per m²) and
the Armani Residences , also in Burj Khalifa, sold
for US$3,500 per sq ft (over US$37,500 per
m²). [14]
The project's completion coincided with the
global financial crisis of 2007–2010 , and with
vast overbuilding in the country, led to high
vacancies and foreclosures. [15] With Dubai
mired in debt from its huge ambitions, the
government was forced to seek multibillion
dollar bailouts from its oil-rich neighbor Abu
Dhabi . Subsequently, in a surprise move at its
opening ceremony, the tower was renamed
Burj Khalifa, said to honour the UAE President
Khalifa bin Zayed Al Nahyan for his crucial
support. [16]
Due to the slumping demand in Dubai's
property market, the rents in the Burj Khalifa
plummeted 40% some ten months after its
opening. Out of 900 apartments in the tower,
around 825 were still empty at that time. [17]

Prestressed concrete

Prestressed concrete is a method for
overcoming concrete 's natural weakness in
tension. It can be used to produce beams , floors
or bridges with a longer span than is practical
with ordinary reinforced concrete. Prestressing
tendons (generally of high tensile steel cable or
rods ) are used to provide a clamping load which
produces a compressive stress that balances the
tensile stress that the concrete compression
member would otherwise experience due to a
bending load. Traditional reinforced concrete is
based on the use of steel reinforcement bars,
rebars, inside poured concrete .
Prestressing can be accomplished in three ways:
pre-tensioned concrete, and bonded or
unbonded post-tensioned concrete.
Pre-tensioned concrete
Stressed ribbon pedestrian bridge,
Grants Pass , Oregon, USA
Pre-tensioned concrete is cast around already
tensioned tendons. This method produces a
good bond between the tendon and concrete,
which both protects the tendon from corrosion
and allows for direct transfer of tension. The
cured concrete adheres and bonds to the bars
and when the tension is released it is transferred
to the concrete as compression by static friction.
However, it requires stout anchoring points
between which the tendon is to be stretched
and the tendons are usually in a straight line.
Thus, most pretensioned concrete elements are
prefabricated in a factory and must be
transported to the construction site, which limits
their size. Pre-tensioned elements may be
balcony elements, lintels, floor slabs, beams or
foundation piles . An innovative bridge
construction method using pre-stressing is the
stressed ribbon bridge design.
Bonded post-tensioned concrete
Prestress post-tension anchor on
display at Instituto Superior
Técnico 's civil engineering
department
Bonded post-tensioned concrete is the
descriptive term for a method of applying
compression after pouring concrete and the
curing process ( in situ ). The concrete is cast
around a plastic, steel or aluminium curved
duct, to follow the area where otherwise tension
would occur in the concrete element. A set of
tendons are fished through the duct and the
concrete is poured. Once the concrete has
hardened, the tendons are tensioned by
hydraulic jacks that react (push) against the
concrete member itself. When the tendons have
stretched sufficiently, according to the design
specifications (see Hooke's law), they are
wedged in position and maintain tension after
the jacks are removed, transferring pressure to
the concrete. The duct is then grouted to protect
the tendons from corrosion. This method is
commonly used to create monolithic slabs for
house construction in locations where expansive
soils (such as adobe clay) create problems for
the typical perimeter foundation. All stresses
from seasonal expansion and contraction of the
underlying soil are taken into the entire
tensioned slab, which supports the building
without significant flexure. Post-tensioning is
also used in the construction of various bridges,
both after concrete is cured after support by
falsework and by the assembly of prefabricated
sections, as in the segmental bridge.
Among the advantages of this system over
unbonded post-tensioning are:
Large reduction in traditional reinforcement
requirements as tendons cannot destress in
accidents.
Tendons can be easily "woven" allowing a
more efficient design approach.
Higher ultimate strength due to bond
generated between the strand and concrete.
No long term issues with maintaining the
integrity of the anchor/dead end.
History of problems with bonded post-
tensioned bridges
The popularity of this form of prestressing for
bridge construction in Europe increased
significantly around the 1950s and 60s.
However, a history of problems have been
encountered that has cast doubt over the long-
term durability of such structures.
Due to poor workmanship of quality control
during construction, sometimes the ducts
containing the prestressing tendons are not fully
filled, leaving voids in the grout where the steel
is not protected from corrosion. The situation is
exacerbated if water and chloride (from de-
icing salts) from the highway are able to
penetrate into these voids.
Notable events are listed below:
The Ynys-y-Gwas bridge in West Glamorgan,
Wales – a segmental post-tensioned structure,
particularly vulnerable to defects in the post-
tensioning system – collapsed without warning
in 1984.
The Melle bridge, constructed in Belgium
during the 1950s, collapsed in 1992 due to
failure of post-tensioned tie down members
following tendon corrosion.
Following discovery of tendon corrosion in
several bridges in England, the Highways
Agency issued a moratorium on the
construction of new internal grouted post-
tensioned bridges and embarked on a 5-year
programme of inspections on its existing post-
tensioned bridge stock.
In 2000, a large number of people were
injured when a section of a footbridge at the
Charlotte Motor Speedway, USA, gave way
and dropped to the ground. In this case,
corrosion was exacerbated by calcium chloride
that had been used as a concrete admixture,
rather than sodium chloride from de-icing
salts.
In 2011, the Hammersmith Flyover in London,
England, was subject to an emergency closure
after defects in the post-tensioning system
were discovered.
Unbonded post-tensioned concrete
Unbonded post-tensioned concrete differs from
bonded post-tensioning by providing each
individual cable permanent freedom of
movement relative to the concrete. To achieve
this, each individual tendon is coated with a
grease (generally lithium based) and covered by
a plastic sheathing formed in an extrusion
process. The transfer of tension to the concrete
is achieved by the steel cable acting against steel
anchors embedded in the perimeter of the slab.
The main disadvantage over bonded post-
tensioning is the fact that a cable can destress
itself and burst out of the slab if damaged (such
as during repair on the slab). The advantages of
this system over bonded post-tensioning are:
1. The ability to individually adjust cables based
on poor field conditions (For example: shifting
a group of 4 cables around an opening by
placing 2 to either side).
2. The procedure of post-stress grouting is
eliminated.
3. The ability to de-stress the tendons before
attempting repair work.
Picture number one (below) shows rolls of post-
tensioning (PT) cables with the holding end
anchors displayed. The holding end anchors are
fastened to rebar placed above and below the
cable and buried in the concrete locking that
end. Pictures numbered two, three and four
shows a series of black pulling end anchors
from the rear along the floor edge form. Rebar
is placed above and below the cable both in
front and behind the face of the pulling end
anchor. The above and below placement of the
rebar can be seen in picture number three and
the placement of the rebar in front and behind
can be seen in picture number four. The blue
cable seen in picture number four is electrical
conduit. Picture number five shows the plastic
sheathing stripped from the ends of the post-
tensioning cables before placement through the
pulling end anchors. Picture number six shows
the post-tensioning cables in place for concrete
pouring. The plastic sheathing has been
removed from the end of the cable and the
cable has been pushed through the black pulling
end anchor attached to the inside of the
concrete floor side form. The greased cable can
be seen protruding from the concrete floor side
form. Pictures seven and eight show the post-
tensioning cables protruding from the poured
concrete floor. After the concrete floor has been
poured and has set for about a week, the cable
ends will be pulled with a hydraulic jack.

Applications
Prestressed concrete is the main material for
floors in high-rise buildings and the entire
containment vessels of nuclear reactors.
Unbonded post-tensioning tendons are
commonly used in parking garages as barrier
cable. [1] Also, due to its ability to be stressed
and then de-stressed, it can be used to
temporarily repair a damaged building by
holding up a damaged wall or floor until
permanent repairs can be made.
The advantages of prestressed concrete include
crack control and lower construction costs;
thinner slabs - especially important in high rise
buildings in which floor thickness savings can
translate into additional floors for the same (or
lower) cost and fewer joints, since the distance
that can be spanned by post-tensioned slabs
exceeds that of reinforced constructions with
the same thickness. Increasing span lengths
increases the usable unencumbered floorspace
in buildings; diminishing the number of joints
leads to lower maintenance costs over the
design life of a building, since joints are the
major focus of weakness in concrete buildings.
The first prestressed concrete bridge in North
America was the Walnut Lane Memorial Bridge
in Philadelphia, Pennsylvania. It was completed
and opened to traffic in 1951. [2] Prestressing
can also be accomplished on circular concrete
pipes used for water transmission. High tensile
strength steel wire is helically-wrapped around
the outside of the pipe under controlled tension
and spacing which induces a circumferential
compressive stress in the core concrete. This
enables the pipe to handle high internal
pressures and the effects of external earth and
traffic loads.
Design agencies and regulations
In the United States, pre-stressed concrete
design and construction is aided by
organizations such as Post-Tensioning Institute
(PTI) and Precast/Prestressed Concrete Institute
(PCI). In Canada the Canadian Precast/
prestressed concrete Institute assumes this role
for both post-tensioned and pre-tensioned
concrete structures.
Europe also has its own associations and
institutes. It is important to note that these
organizations are not the authorities of building
codes or standards, but rather exist to promote
the understanding and development of pre-
stressed design, codes and best practices. In the
UK, the Post-Tensioning Association fulfills this
role. [3]
Rules for the detailing of reinforcement and
prestressing tendons are provided in Section 8
of the European standard EN 1992 -2:2005 -

CarbonCast

CarbonCast is a precast concrete technology
that uses carbon-fiber grid as secondary
reinforcing or as a shear truss. It was introduced
by AltusGroup, Inc. , a national partnership of
14 precast concrete manufacturers and seven
industry suppliers founded to expedite the
research and national commercialization of
concrete innovations.
Products
The CarbonCast line of products includes:
CarbonCast High Performance Insulated
Wall Panels are composed of two concrete
wythes separated by continuous insulation and
connected by C-GRID carbon fiber shear
trusses [1][2]
CarbonCast Insulated Architectural
Cladding feature inner and outer wythes
1-3⁄4″thick or more for a total concrete
thickness of 3-1⁄2″. The wythes sandwich a
layer of insulation of usually 2″ or more
depending on R-value requirements [3]
CarbonCast Architectural Cladding employs
a steel reinforced Vierendeel-like truss frame
attached to a thin, C-GRID reinforced
diaphragm face. Insulating foam forms around
patented V-ribs, designed to create a thermal
break with the face of the panel, and displaces
concrete to provide insulation while C-GRID
carbon fiber shear trusses mechanically link
the face and truss ribs[4][5]
CarbonCast Double Tees replace
conventional steel mesh reinforcing in the
flange with C-GRID carbon fiber grid [6]
Properties
The use of carbon fiber grid over conventional
reinforcement yields a number of unique
properties to CarbonCast components: [7]
Lower weight - When carbon fiber grid
replaces steel mesh in the face of concrete
products, manufacturers can use less concrete
cover to protect the mesh from corrosive
elements. Non-corrosive carbon fiber
eliminates the need for extra concrete
Improved thermal performance - The
relatively low thermal conductivity of carbon
fiber permits CarbonCast components to
provide higher R-values than conventional
precast concrete
Improved strength - Carbon fiber is four times
stronger than steel by weight providing better
surface crack control when used as secondary
reinforcing and 100% composite action when
used as a truss in insulated wall panel
Comparable cost - Many applications receive
savings in foundation and super structure
(reduced weight), energy costs (insulation) and
maintenance (reduced corrosion)
Applications
There are more than 300 projects totaling more
than 17,000,000 square feet (1,600,000 m 2 )
of surface area of CarbonCast technology in
these markets:
Education
Industrial/Warehouse
Commercial Office
Parking Structure
Multi-Family Residential
Retail
Examples
Prominent structures that have used CarbonCast
technology include:
Proximity Hotel , Greensboro, NC
Lucas Oil Stadium , Indianapolis, IN
University Commons at Georgia State
University , Atlanta, GA

Precast concrete

Precast concrete is a construction product
produced by casting concrete in a reusable mold
or "form" which is then cured in a controlled
environment, transported to the construction
site and lifted into place. In contrast, standard
concrete is poured into site-specific forms and
cured on site. Precast stone is distinguished
from precast concrete by using a fine aggregate
in the mixture, so the final product approaches
the appearance of naturally occurring rock or
stone.
By producing precast concrete in a controlled
environment (typically referred to as a precast
plant), the precast concrete is afforded the
opportunity to properly cure and be closely
monitored by plant employees. Utilizing a
Precast Concrete system offers many potential
advantages over site casting of concrete. The
production process for Precast Concrete is
performed on ground level, which helps with
safety throughout a project. There is a greater
control of the quality of materials and
workmanship in a precast plant rather than on a
construction site. Financially, the forms used in
a precast plant may be reused hundreds to
thousands of times before they have to be
replaced, which allows cost of formwork per
unit to be lower than for site-cast production. [1]
Many states across the United States require a
precast plant to be certified by either the
Architectural Precast Association (APA), National
Precast Concrete Association (NPCA) or Precast
Prestressed Concrete Institute (PCI) for a precast
producer to supply their product to a
construction site sponsored by State and Federal
DOTs.
There are many different types of precast
concrete, forming systems for architectural
applications, differing in size, function, and cost.
Precast architectural panels are also used to clad
all or part of a building facade free-standing
walls used for landscaping, soundproofing, and
security walls, and some can be Prestressed
concrete structural elements. Stormwater
drainage, water and sewage pipes, and tunnels
make use of precast concrete units. The New
South Wales Government Railways made
extensive use of precast concrete construction
for its stations and similar buildings. Between
1917 and 1932, they erected 145 such
buildings. [2]
Brief history
Ancient Roman builders made use of concrete
and soon poured the material into moulds to
build their complex network of aqueducts ,
culverts, and tunnels. Modern uses for pre-cast
technology include a variety of architectural and
structural applications featuring parts of or an
entire building system.
In the modern world, pre-cast panelled
buildings were pioneered in Liverpool , England
in 1905. A process was invented by city
engineer John Alexander Brodie, whose
inventive genius also had him inventing the
football goal net. The tram stables at Walton in
Liverpool followed in 1906. The idea was not
taken up extensively in Britain. However, it was
adopted all over the world, particularly in
Eastern Europe. [3]
Precast Concrete Products
The following is a sampling of the numerous
products that utilize precast/prestressed
concrete. While this is not a complete list, the
majority of precast/prestressed products can fall
under one or more of the following categories:
Agricultural Products
Precast concrete products can withstand the
most extreme weather conditions and will hold
up for many decades of constant usage.
Products include bunker silos, cattle feed bunks,
cattle grid , agricultural fencing, H-bunks, J-
bunks, livestock slats, livestock watering trough,
feed troughs, concrete panels, slurry channels,
and more. Prestressed concrete panels are
widely used in the UK for a variety of
applications including agricultural buildings,
grain stores, silage clamps, slurry stores,
livestock walling, and general retaining walls.
Panels can either be used horizontally and
placed either inside the webbings of RSJs ( I-
beam ) or in front of them. Alternatively panels
can be cast into a concrete foundation and used
as a cantilever retaining wall.
Building and Site Amenities
Precast concrete building components and site
amenities are used architecturally as fireplace
mantels, cladding, trim products, accessories,
and curtain walls. Structural applications of
precast concrete include foundations, beams,
floors, walls, and other structural components.
It is essential that each structural component be
designed and tested to withstand both the
tensile and compressive loads that the member
will be subjected to over its lifespan. [1]

used in the construction, safety and site
protection of road, airport and railroad
transportation systems. Products include: box
culverts, 3-sided culverts, bridge systems,
railroad crossings, railroad ties, sound walls /
barriers, Jersey barriers , tunnel segments,
precast concrete barriers, TVCBs, central
reservation barriers and other transportation
products. Used to make underpasses, surface-
passes and pedestrian subways, so that traffic in
cities is disturbed for less amount of time. [6]

Marine Products
Floating docks, underwater infrastructure,
decking, railings and a host of amenities are
among the uses of precast along the waterfront.
When designed with heavy weight in mind,
precast products counteract the buoyant forces
of water significantly better than most materials.
[9]
Modular Paving
Available in a rainbow of colors, shapes, sizes
and textures, these versatile precast concrete
pieces can be designed to mimic brick, stone or
wood. [10]
Prestressed/Structural Products
Prestressing is a technique of introducing
stresses of a predetermined magnitude into a
structural member to improve its behavior. This
technique is usually found in concrete beams,
spandrels, columns, single and double tees, wall
panels, segmental bridge units, bulb-tee girders,
I-beam girders, and others. "Prestressed
member are crack-free under working loads
and, as a result, look better and more
watertight, providing better corrosion protection
for the steel." Many projects find that
prestressed concrete provides the lowest overall
cost, considering production and lifetime
maintenance. [4]
Reinforced Concrete Box
a reinforced concrete box being
used in a storm drain
RCC Magic Box , used to build an
underpass at Madiwala at the
junction of Hosur Road and Inner
Ring Road , Bangalore City.
A reinforced concrete box , referred to as a
box culvert in the UK, is a square or rectangular
"pipe" made of concrete with rebar or wire
mesh fabric strewn throughout for the addition
of extra strength. Multiple such boxes are
arranged sideways to make a pipe or tunnel like
structure.
It is often used for sanitary sewer trunks, storm
drain spillways, pedestrian subways, utility
tunnels, catch basins, and other similar
underground passage ways. Due to the
enormous strength of reinforced concrete , it is
often used in sewers or tunnels that have little
cover above them which means they will be
subjected to the stress of the road atop them. In
India, pre-cast concrete boxes known as "Magic
Boxes"" are used for the construction of flyovers
and underpasses . [11]
Double Wall Precast — Concrete
Sandwich Panels
The double wall process has been in use in
Europe for many years. The walls consist of two
wythes of concrete separated by an insulated
void. The most commonly specified thickness of
the wall panels is 8 inches. The walls can also be
built to 10 and 12 inches thick if desired. A
typical 8-inch wall panel consists of two wythes
(layers) of reinforced concrete (each wythe is
2-3/8 inches thick) sandwiched around
3-1/4 inches of high R-value insulating foam.
The two wythes of the interior and exterior
concrete layers are held together with steel
trusses. Concrete sandwich panels held together
with steel trusses are inferior to those held
together with composite fibreglass connectors.
This is because the steel creates a thermal
bridge in the wall, significantly reducing the
insulative performance and reducing the ability
of the building to utilise its thermal mass for
energy efficiency. There is also the risk that
because steel does not have the same expansion
coefficient as that of concrete, as the wall heats
and cools, the steel will expand and contract at
a different rate to the concrete, which can cause
cracking and spalling (concrete "cancer").
Fibreglass connectors that are specially
developed to be compatible with concrete
significantly reduce this problem. [12] The
insulation is continuous throughout the wall
section. The composite sandwich wall section
has an R-value exceeding R-22. The wall panels
can be made to any height desired, up to a limit
of 12 feet. Many owners prefer a 9-foot clear
height for the quality of look and feel it affords a
building.

The walls can be produced with smooth surfaces
on both sides because of the unique
manufacturing process, which form finishes
both sides. The walls are simply painted or
stained on the exterior surface to achieve the
desired color or textured surface. When desired,
the exterior surface can be manufactured to
have a wide variety of brick, stone, wood, or
other formed and patterned appearances
through the use of reusable, removable
formliners . Interior surfaces of the double-wall
panels are drywall quality in appearance right
out of the plant, requiring only the same prime
and paint procedure as is common when
completing conventional interior walls made of
drywall and studs.
Window and door openings are cast into the
walls at the manufacturing plant as part of the
fabrication process. Electrical and
telecommunications conduit and boxes are
flush-mounted and cast directly in the panels in
the specified locations. The carpenters,
electricians, and plumbers do need to make
some slight adjustments when first becoming
familiar with some of the unique aspects of the
wall panels. However, they still perform most of
their job duties in the manner to which they are
accustomed.
Double-wall precast concrete sandwich panels
can be used on most every type of building
including but not limited to: multi-family,
townhouses, condominiums, apartments, hotels
and motels, dormitories and schools, and
single-family homes. Depending upon building
function and layout, the double-wall panels can
be easily designed to handle both the structural
requirements for strength and safety, as well as
the aesthetic and sound attenuation qualities the
owner desires. Speed of construction, durability
of finished structure, and energy-efficiency are
all hallmarks of a building that utilizes the
double-wall system.
