Steel Shots: Raise the Roof

Structural steel is raising the roof of a 440,000-sq.-ft warehouse in Jamesburg, N.J.

How to expand a building without using more land? Raise the roof. 
 
AISC-member fabricator and erector Industrial Services Enterprises (ISE) in Randolph, N.J., has used this innovative system on buildings for decades to increase ceiling height for warehousing, mezzanines, high bay equipment and other uses. The process involves lifting the entire existing roof intact (including all utilities) and re-supporting the roof on the existing framework of the building using all structural steel elements, saving the costs of building a new structure.
 
In Jamesburg, N.J., ISE’s patented E-Z Riser roof raising system is lifting the roof of a 440,000-sq.-ft warehouse by 21 feet to create a 45-ft clear height building. All of the design, engineering, steel fabrication and erection was done in-house. The roof is raised in four sections with ISE’s hydraulic lifting process then bolted or welded to the structural steel elements (390 tons of structural steel is being used on the project). The final lift for the project will be held next month.
