1989 NY Times article on WTC 7 steel redundancy

[boastOne43]

snippet:


BEFORE it moves into a new office tower in downtown Manhattan, Salomon Brothers, the brokerage firm, intends to spend nearly two years and more than $200 million cutting out floors, adding elevators, reinforcing steel girders, upgrading power supplies and making other improvements in its million square feet of space...

In some office buildings, that alteration would be impossible, but Silverstein Properties tried to second-guess the needs of potential tenants when it designed Seven World Trade Center as a speculative project.

''We built in enough redundancy to allow entire portions of floors to be removed without affecting the building's structural integrity, on the assumption that someone might need double-height floors,'' said Larry Silverstein, president of the company. ''Sure enough, Salomon had that need...

MORE than 375 tons of steel - requiring 12 miles of welding - will be installed to reinforce floors for Salomon's extra equipment. Sections of the existing stone facade and steel bracing will be temporarily removed so that workers using a roof crane can hoist nine diesel generators onto the tower's fifth floor, where they will become the core of a back-up power station.

Titanic was constructed with sixteen watertight compartments. Each compartment had doors that were designed to close automatically if the water level rose above a certain height. The doors could also be electronically closed from the bridge. Titanic was able to stay afloat if any two compartments or the first four became flooded.


Nine diesel generators on the fifth floor?

Jiminy Christmas... hey, where'd we put that guy who wanted to build a demolition mechanism into his office building?
