See how JBrennon completed a vacuum-jacketed cryogenic piping upgrade in an active facility, replacing compromised piping with a tested stainless-steel system while coordinating shutdown, installation, and final restoration.

JBrennon completed a Morgantown freight elevator replacement inside an active research and laboratory facility. The turnkey project replaced the hydraulic power unit, controller, wiring, doors, safety devices, cab, accessible fixtures, and fire-alarm interfaces with maintainable, non-proprietary systems.

JBrennon completed design-build elevator pit remediation at an active industrial facility after demolition exposed a concealed subsurface void and undocumented structural conditions. The revised work included exploratory investigation, engineered formwork, 23 cubic yards of concrete infill, high-strength grout placement, strength testing, and final pit restoration.
