Steel Shots: Crown Jewel

The signature top of Arlington, Va.’s new 35-story, 580,000-sq.-ft office tower at 1812 N. Moore St. is a decorative structural steel “crown.”

The roof structure — engineered, fabricated and installed by American Iron Works, Inc. (an AISC member and AISC Certified fabricator/Advanced Certified erector) — was fabricated over the course of about seven months and a team of ironworkers assembled the structure in just four nights.

AIW expanded their Maryland shop to allow for full fit-up of the structure. They embedded the steel columns at the upper floors, welded base plates at the top and then let the pinned anchors fall into place before welding. This complicated structure was required to be shipped in certain parts, which had to be delivered upside down, and all construction was required to take place at night.  

The project recently won a 2014 WBC Craftsmanship Award for Structural Steel Framing by the Washington Building Congress.
