Washington D.C. Convention Center

The footprint for this massive project occupies seventeen 
acres on six city blocks.  There are more than 1,400 trusses 
ranging in length from 90 feet to 180 feet.  The convention 
center covers 2.3 million square feet, including one exhibit 
hall measuring 180 feet by 720 feet of clear-span space.  


With five stories above ground and 77 feet below grade, 
this project is exceptional in scale and profile.  NSC 
coordinated the efforts of 15 detailing shops to create 
more than 19,000 drawings for the project.  Oversized 
steel had to be shipped in from a marshalling yard 20 
miles away at night.  


NSC's scope of work included erecting seven blocks of 
viaducts for three different streets.  Even with the 
enormity of the project and numerous obstacles, the 
structural steel was completed on time.
