SaddleBack College Science Building

SaddleBack College Science Building, Mission Viejo Ca

Project Description:

This project is an 80,000+ square foot 3-story space and is located at the Saddleback College Campus in Mission Viejo, CA.

The Saddleback College Interdisciplinary Science Building reflects the high aspirations of SOCCCD for both their award winning science program and the forward thinking reputation of the campus. Designed to be LEED Platinum Certified, it is envisioned as a state-of-the-art science teaching and research laboratory as well as a magnet for the entire student body.

Scope of Work:

TMCx Solutions provided a systematic process of documented confirmation of the Commissioned Systems’ functionality and compliance with the design criteria set forth in the project plans and specifications. This process provided you, the Customer, with an unbiased, objective view of the Commissioned Systems’ installation, documentation, operation and functionality.

For this project, the scope included the Prerequisite Fundamental Commissioning as well as Enhanced

Commissioning services as required for a LEED certification

Project Snapshot:

  • Owner:  South Orange County Community College District
  • Project Size:  80,000 sq. ft.
  • Construction Cost:  $67M
  • GC:  CW Driver
  • Year of Completion:  2016


  • Air Handling Units
  • Exhaust Systems
  • Laboratory Control Systems
  • Terminal Units (VAV Boxes and CRAC Units)
  • Plumbing
  • Electrical – Lighting Controls

Challenges & Successes:

  • Issue: Overcooling in the spaces

          Resolution: Multiple reheat valve malfunctions were repaired. Also, the AHU DAT setpoint reset control was optimized to prevent rogue spaces from unduly influencing the reset control. Benefit: The space temperature is maintained accurately. Issue: The temperature setback for the Labs was not programmed. Resolution: The BAS was programmed to index the Lab Controls to unoccupied mode setbacks.

  • Issue: Redundancy of the controls such that if the controls for one of the units within the pair failed, the other unit would continue operate.

          Resolution: the BMS programming was modified to allow seamless redundancy. Benefit: The lab controls are a critical component. A failure of supply air could cause excessive negative pressures and/or an inability of the system to provide adequate fume hood exhaust.
