PROJECT DESCRIPTION
Upgraded MEP systems throughout the 135,000 SF building and added a 4,000 SF two-story science wing addition.

ELECTRICAL SYSTEMS
New 2,500-amp electric service bringing building from 208/3Ø to 480/3Ø.
New lighting throughout building for energy savings. Upgraded fire alarm to ADA throughout.
Added receptacles and panelboards for expanded data systems.

PLUMBING SYSTEMS
