9. STEEL AND THE SKYSCRAPER
Henry Bessemer (1813-1898) is the man whose
name we associate today with one of the major
processes of producing steel.
It was Bessemer's discovery of a process for
making steel cheaply which led to its use in the
construction industry.
George A. Fuller (1851-1900), as a young man,
was employed in his uncle's architectural office,
drawing building plans. He soon became interested
in the problem of load bearing capacities and how
much weight each part of a building would carry.

23. Golden Gate Bridge
When the bridge opened in 1937, with a main
suspension span length of 4,200 feet, it was the
longest in the world. The engineering obstacles
poised by the mile-wide, turbulent Golden Gate
Strait led engineers to devise a bridge that
required four years to build, 83,000 tons of steel,
389,000 cubic yards of concrete, and enough
cable to encircle the earth three times.
24. Previous ASCE designations
for the Golden Gate Bridge
include: the National Civil
Engineering Landmark (1984)
and Seven Wonders of the
World (1955). Other significant
bridges include the VerrazanoNarrows Bridge, the George
Washington Bridge, the Akashi
Kaikyo (Japan) and the
Humber Bridge (England).

32. NETHERLANDS NORTH SEA PROTECTION
WORKS
This singularly unique,
vast and complex system
of dams, floodgates,
storm surge barriers and
other engineered works
literally allows the
Netherlands to exist
The North Sea Protection
Works exemplifies the
ability of humanity to exist
side-by-side with the
forces of nature.
36. The piers
The construction of each pier almost took
one and a half years. One started building a
new pier every two weeks. This way, thirty
piers were in production at the same time. It
took an enormous amount of organisation
and planning to finish the giant and complex
structures in time. People worked day and
night, because otherwise the concrete could
not harden properly. The sixty-five piers were
each between 30.25 and 38.75 metres high
and weighed 18,000 tonnes. Two extra piers
were built, for safety’s sake. Visitors of
Neeltje Jans, the former artificial island, can
now climb one of these left-over piers.
The piers were the most important elements of the
dam. They were produced in a building excavation
with a surface area of about one square kilometre,
located 15.2 metres below sea level. A ring-dike
kept the sea water outside the excavation. The dry
dock consisted of four parts. When the piers of
one part were finished, this part would be flooded.
The lifting ship then sailed into the dock, lifted the
heavy pier and shipped it off to its place in the
barrier. Each pier consisted of 7,000 cubic metre
of concrete. Therefore, the dock may also be
typified as a large concrete factory in which
450,000 cubic metre of concrete was
manufactured between 1979 and 1983.
37. The placement
When all the piers were finished, the building
excavation in which they were built, was
flooded. Two ships took the piers to the right
place. The ship Ostrea could lift the piers one
by one and sailed them to a floating pontoon.
This pontoon marked the place where the
pier should be sunk.
When the piers stood firmly on the
bottom of the Oosterschelde, the
construction of the barrier could be
finished. The piers were raised with the
top-pieces, upon which the slides were
fixed. Hollow tubes were placed on the
piers, and on top of this came a road.
The tubes provided room for the
equipment responsible for making the
slides move.
Slides
38. Mytilus (mussel)
This ship made sure that the bottom of
the Oosterschelde was compressed
along the section were the barrier would
be built. When the bottom is
compressed, the sand and clay parts
are compacted more closely to each
other. The bottom becomes more solid.
Without the work of the Mytilus, the barrier
would not have been as firm. The entire
compression process took place under
water and continued twenty-four hours per
day. The needles transferred vibrations to
the sea bottom, with a frequency of
between 25 and 30 Hertz and an amplitude
of 4 to 5 millimetres.
39. Cardium (cockle)
Although the Ostrea was the most impressive ship of the fleet,
the Cardium was the most expensive one. The Cardium carried
out an important task: putting down the mats. These mats which
were thirty-six centimetres thick, forty-two metres wide and two
hundred metres long. The synthetic mats were filled with sand
and gravel in a factory. The mats were put on the sea bottom at a
rate of ten metres every hour. An extra mat was put at the areas
where the piers were to be placed. This was to protect the mats
against wear, which could be developed through the opening and
closure of the slides.
40. The Ostrea (oyster)
The Ostrea was the flagship of the Delta fleet.
With its length of eighty-seven metres, the
typical U-shape and a capability of 8,000
horsepower, it was the most impressive ship.
The ship lifted the piers from the dry dock and
sailed them to the place of the barrier. With
the open side of the ‘U’, the ship manoeuvred
around the pier.
The ship could steer easily, thanks to its four screw
propellers. On both sides there were two porches fifty
metres high. The piers were fixed to these porches. The
porches could not lift more than 10,000 tonnes however,
whereas the piers weighed 18,000 tonnes. So how did the
Ostrea put the piers in the right place? Fortunately, the
levers did not have to lift the piers completely out of the
water. The most important factor was that they did not
touch the bottom of the sea during transportation. Because
of the upward pressure of the water, the levers needed to
provide less power.
41. Macoma (nun)
This pontoon, named after a shellfish,
was situated exactly in front of the
place where a pier would be placed.
When the Ostrea had taken a pier, it
moored against the Macoma. To
offer the Ostrea some stability, the
pontoon had a coupling mechanism
with a power of six hundred tonnes.
The Macoma also had a second
function: an enormous vacuum
cleaner was used to ensure there
was no sand between the pier and
the bottom. This was an extremely
difficult job, because the tidal
movements moved large amounts of
sand each day.
42. Jan Heijmans
Another ship, the Jan Heijmans,
helped the Cardium place the
mattresses. The Jan Heijmans was
also responsible for the filling of the
holes between the mattresses and the
gravel. The Macoma worked together
with the Sepia and the Donax I during
the placement of gravel ballast mats
on the bottom.
43. Maeslant barrier
The most important demand for the
design was that the barrier should not
hinder the shipping. The barrier should
only be closed under exceptional
circumstances - no more than once or
twice every ten years. In 1991, four years
after the competition was held,
construction started. Which design had
won? Out of six submissions, the design
of the Building Combination Maeslant
Barrier won. The Maeslant barrier would
consist of two steel doors which could be
sunk down and could be turned away in
the docks in the shores.
44. BOS and BES
The Maeslantkering is operated by a computer. In the
case of a storm flood, the decision of whether or not to
close the barrier is left to a computer system (BOS).
The chance of mistakes is greatly increased if people
were to make the decision. A computer will only follow
predefined procedures, it doesn’t get its own ideas and
it is not affected by poor environmental conditions. The
system only takes into account the water and weather
forecasts. On that basis it calculates the expected
water levels in Rotterdam, Dordrecht and Spijkenisse.
When the BOS decides to close the barrier, it gives
orders to another computer system, the BES. The BES
carries out the orders of the BOS. The system operates
entirely automatically, but remains under constant
human supervision with regards to the procedures.
45. Movement works
The movement works are
operated from control buildings
at the north and south side. The
movement works consist of
three parts: the dock gate, the
locomotive and the ballast
system of the retaining wall.
The dock gate opens when the
barrier is activated. The barrier
is driven into the New Waterway
by the locomotive. The ballast
system allows the barrier to sink.

The Millau Viaduct (French: le Viaduc de Millau) is
a large cable-stayed road-bridge that spans the valley
of the River Tarn near Millau in southern France.
Designed by Lord Foster of Foster and Partners, and
bridge engineer Michel Virlogeux, it is the tallest
vehicular bridge in the world, with one mast's summit
at 343 metres (1,125 ft) — slightly taller than the
Eiffel Tower and only 38 m (125 ft) shorter than the
Empire State Building.
The viaduct is part of the A75-A71 autoroute axis
from Paris to Béziers. It was formally dedicated on 14
December 2004 and opened to traffic two days later.
