Northwest Midfield Terminal

NSC used an innovative erecting technique to put 
the roof into place on the terminal.  The soaring 
design of the new one mile-long, two-million-square-foot 
airport terminal with high arched ceilings, open spaces 
and large gate areas, inspired the remarkably resourceful 
approach to raising the roof into position.


A large percentage of the steel for the roof was ground-
assembled in eight-bay segments.  Once NSC
completed the structural steel components, follow-on 
trades had a 20-day window to install the finished 
systems.  Then, using an engineering lifting system 
comprised of 16 jacks, one on each side of the bay 
segments, stationed on top of the columns, the entire 
roof was elevated at once.
