In order to install laboratory equipment weighing in excess of 90,000 lbs, Avid Radiopharmaceuticals needed to reinforce the steel floor structure of their facility to support the extra weight.

This drawing shows the new and existing steel structure and how it’s installed.

The installation of new steel beams underneath the existing beams transfer the load to the existing steel columns.

Survey of the existing steel confirmed the sizes and locations and helped us determine if there were any deflection or sag in the beams already in place. Once the new steel was fabricated we removed the ceiling, relocated heating and sprinkler piping, and installed the new steel beams.

Clip angles were installed on the columns, then new cross beams beneath the existing steel, then new long span beams. Shims between the beams help create a unified support structure.

Once all was bolted and inspected, spray fireproofing was applied to the new steel and exposed areas of the existing structure. The last step was re-installed the ceiling.
