NSC delivered large-span structural steel erection for one of the nation’s premier convention centers, supporting iconic long-span roof structures and expansive column-free exhibit halls in Orlando, Florida
Project Specific Details
Erected long-span roof truss systems spanning approximately 250–300 feet to create large, column-free exhibit halls
Primary roof trusses ranged up to 30–35 feet in depth, enabling efficient load distribution over wide spans while controlling deflection under service and event loads
Installed 15,000 tons of structural steel supporting one of the largest contiguous convention center expansions in the United States
Roof framing designed to carry high superimposed loads, including suspended lighting, signage, temporary exhibits, and show infrastructure, without intermediate supports
Truss bottom chords and secondary framing configured to act as integral rigging and service platforms, eliminating the need for supplemental support steel
Erection sequencing required temporary stabilization of partially erected trusses prior to full diaphragm completion, demanding precise crane choreography and lift planning
Tight erection tolerances were critical to ensure proper camber alignment and chord geometry across long roof runs, particularly where trusses tied into perimeter frames
Field connections included large bolted and welded assemblies, with fit-up accuracy essential to maintaining overall roof profile and diaphragm performance
Steel erection coordinated with concurrent enclosure and interior build-out activities to maintain aggressive schedule milestones across multiple exhibit halls
