Part 1 of our series: The Importance of Building Commissioning starts as an overview to the Commissioning process and what all it entails. Next week, we will review specific tasks during construction.
The Owner’s Project Requirements (OPRs) are drafted by using the owner & user requests and the LEED checklist as source documents. The OPR details the functional requirements of a project and the expectations of how it will be used and operated. It is intended to serve as a guide for the design, construction and commissioning efforts. The Basis of Design (BOD) is then drafted by the design team in response to the OPR. A BOD includes design information necessary to accomplish the owner’s project requirements, including system descriptions, indoor environmental quality criteria, other pertinent assumptions (such as weather data), and references to applicable codes, standards, regulations and guidelines. The BOD addresses HVAC, lighting / lighting control and domestic hot water systems. The Commissioning Agent (CxA) reviews the design documents at about the 50% CD stage for agreement with the OPR, the BOD, for coordination and code compliance issues. A Commissioning Plan is then drafted by the CxA and presented to the construction team during commissioning Kick Off meeting.
