Project Profile

111MW Data Center

FSG’s Dallas team quickly recognized that building the rooftop conduit racking system for this 111MW data center in the field would create unnecessary risk. By moving the entire scope to FSG’s San Antonio prefab shop, the team produced complete assemblies that were delivered to the site and lifted to the roof in a streamlined, predictable process.

FSG Prefab’s Custom Solutions provide project-specific prefabricated assemblies designed to support unique layouts, site conditions, and installation challenges. When standard assemblies do not meet project requirements, FSG works from provided drawings, specifications, or coordination models to deliver job-ready solutions that improve efficiency and reduce onsite labor.

Custom solutions can be applied across all phases of construction, including underground, deck and CMU walls, overhead, in-wall rough-in, electrical rooms, rooftop installations, data and low voltage systems, and lean jobsite support.
