Design-Build
We take a project from schematic design through commissioning — one team responsible for engineering, fabrication, and install.

Overview
Design-Build in the SF Bay Area
T3 Mechanical delivers mechanical design-build for new construction and tenant improvements throughout the Bay Area, carrying a project from schematic design and engineered drawings through in-house fabrication, field execution, and commissioning. One team owns the outcome, which removes the handoffs and finger-pointing that slow conventional bid-build projects.
We produce shop submittals, coordinate permits, and deliver as-built documentation at closeout, working tightly with general contractors to hold schedules that don't slip. Self-performing fabrication and install from our Livermore headquarters keeps quality and timeline in our control. CA Lic # 1038631.
