Construction Facts

There are more than 10 million bricks in the Empire State Building!

When the road authority drew up plans for a major highway in 2012, Iceland's elf communicators filed objections. The route was rerouted around an "elf church" rock formation in Galgahraun. Surveyors quit. Bulldozers broke. Construction companies hired professional elf mediators to negotiate. Over 50% of Icelanders refuse to deny hidden people exist. The elves have planning permission.

The Gateway Arch was built as two separate legs measured to meet precisely at the top. On October 28, 1965, the morning sun expanded the south leg. The last piece would not fit. Workers ran fire hoses to the top and soaked the steel until it shrank. Hydraulic jacks applied 450 tons of force, and the final section slid in.

Joseph Strauss spent $130,000 on a safety net under the Golden Gate Bridge during construction - the most expensive safety device ever built for a bridge at the time. It saved 19 men who fell from the deck. Those survivors formed a club: the Halfway to Hell Club.

The Washington Monument is two different shades of marble. Construction started in 1848 but funding collapsed in 1854, halting work for over 20 years. When the Army Corps of Engineers resumed building in 1879, the original Maryland quarry could no longer supply matching marble. Builders used stone from a new source - and it aged to a slightly darker shade. The color line sits about one-third of the way up the 555-foot tower.

The White House interior is a 1950s building. Engineers found it near collapse in 1948. Margaret Truman's piano leg had just crashed through the floor. Workers gutted every floor down to the bare exterior walls. A new steel frame went up inside the hollow shell, foundations dug 20 feet deep. To protect the 1817 walls, they disassembled a bulldozer and rebuilt it inside.

Justo Gallego Martinez spent 60 years building a full-scale cathedral by himself in Mejorada del Campo, Spain. He had no architectural training, no blueprints, and no building permits. He used recycled junk - stacked oil drums for pillars, bicycle wheels as molds, broken glass for windows - on land he inherited. He died in November 2021, aged 96, with the cathedral still unfinished.
