Las Positas Community College

Southland Industries provided design-build services for a new 3,600 square foot central utility plant with 600 tons of cooling using ice storage technology and 14,700 MBH of heating with future capacity. Southland acted as the general contractor on this project, reporting directly to Las Positas Community College. Southland's field staff completed all HVAC and plumbing work directly, while controls, fire protection, electrical and civil trades were completed by subcontractors.

Project Highlights

  • The central utility plant included the installation of (2) 300 Ton Chillers, (21) 451 ton-hour thermal storage units, (2) 7,350 MBH boilers, 2 cooling towers, 12 pumps, 3 heat exchangers, and 8,600 liner feet of underground heating and cooling piping throughout the campus.
  • The pre-engineered building housing much of the central utility plant equipment was particularly challenging due to the lack of structural integrity, compared to a standard structure. All piping was required to be braced to the floor, creating space constraints. Southland coordinated seismic bracing and exterior attachments with the building manufacturer to overcome the challenge.
  • A new natural gas main was distributed underground to specific buildings, as well as up to (12) 4" conduits for a new IT campus infrastructure loop to all buildings.
