Proposal, dated July 7, 2020 2658
PURPOSE: To authorize the County Manager to execute a contract upon review by the County
Attorney, between Orange County and Facilities Dynamics Engineering to perform building
commissioning services for the Northern Campus construction project.
BACKGROUND: On September 3, 2019, the County voted to accept a Guaranteed Maximum
Price (GMP) of $36,354,082 as presented by Bordeaux Construction for the development of the
Orange County Northern Campus. The Campus, located on Highway 70 in Hillsborough, is
intended to include a replacement Detention Center, Environment and Agriculture Center, and a
Parks Base. The construction of this project is now in progress and is expected to be finished by
July of 2021.
Building commissioning (Cx) is an integrated, systematic process to ensure, through documented
verification, that all building systems perform interactively according to the "Design Intent". The
focus of this commissioning will be electrical, mechanical, plumbing and heating, ventilation, and
air conditioning (HVAC) systems in all three facilities. These systems will be inspected, tested
and balanced according to established standards prior to the Owner's acceptance. The
commissioning agent provides a third party, independent, assessment of building functionality,
reporting inspection and test results to the Owner.
The performance of building commissioning will provide necessary quality assurance of building
systems prior to Owner acceptance of the completed project.

FINANCIAL IMPACT: Facilities Dynamics Engineering was selected through an RFQ process
and has provided a quote of$109,816 to provide these services for the Northern Campus project.
There are adequate Owner's Contingency funds available to cover the cost of this proposal.
SOCIAL JUSTICE IMPACT: There are no social justice impacts as a result of this request.
ENVIRONMENTAL IMPACT: Commissioning of this project will ensure building systems are
operating in an optimal, energy and resource efficient fashion.
RECOMMENDATION(S): The Manager recommends that the Board authorize the County
Manager to execute the contract upon review by the County Attorney, between Orange County
and Facilities Dynamics Engineering to perform building commissioning services for the Northern
Campus construction project.
