This design-assist project complies to LEED Credit EQc4 requirements. We performed extensive amounts of multi-trade prefabrication on this project. The fit-out of the third-floor shell space was added to our scope after the project started. Since the building was already enclosed, this required an on-site paint booth and multi-trade rack fabrication in the shell space.
The multi-trade racks are located throughout the project in every corridor. Since there are no ceilings in the corridors, this was our first exposed installation of our multi-trade prefabrication.

This was a new building with 90,000 Square Feet of primarily Laboratory Space. The project had a requirement of obtaining LEED Silver. Rock Hill played an integral part in meeting this goal by the implementing of an efficient design, running an energy model, and by carrying out the LEED required documentation prosses. Rock Hill led the MEP virtual pre-construction coordination prosses. The extensive coordination prosses allowed the team to prefabricate a large amount of buildings MEP systems with great success. Rock Hill also facilitated, built, and installed multi-trade racks in the corridors of the two lab floors resulting in a cleaner installation, and a shortened construction schedule.
