3 The and is covered in a special coating that prevents contrast between this warm, wet light and solar heat from penetrating the air and the cool interior of the building. The coating cannot block the infrared building leads to condensation, energy that radiates back from the hot desert which can discolor the Burj’s cladding. Moisture buildup can even lead to electric shorts within the building. One of the tower’s environmentally friendly features is a collection system that captures condensation, sand, however.

Construction crews also found the cold conditions challenging. ”5 PUTTING IT ALL TOGETHER When components were ready for installation, sledges named Turtle and Lobster carried them from the casting yard to a jetty where Svanen could pick them up. The crane transported each piece to the growing bridge and lowered it into position. Like cord inside a beaded necklace, steel tendons pulled the concrete components together and held them in place. A single tendon contained between four and 31 cables, each one a 41 SURVEYING WITH SATELLITES To ensure precise placement of bridge talking to the GPS gurus who were working components, Svanen used the Global on improved versions of the system,” SCI Positioning System (GPS).

29 Giannelia’s plans called for a sturdy, functional design. SAFE DRIVING Long, straight roads can have a hypnotic effect on drivers, making them less alert to potential hazards. To increase the safety of Confederation Bridge, engineers designed it with a gentle, S-shaped curve, forcing drivers to pay more “We had to have the best technical solution,” he said. ”3 Competition was not the only challenge Giannelia faced. PWC insisted on a significantly attention. The idea came from higher safety rating than the one specified for Robert Dewar, a professor at ordinary North American highway bridges.
