Obtain all required project documentation (Specifications, Design Drawings, OPR, BOD, schedules). Establish communications protocol for project. Task 2 - Review of Owner Project Requirements (OPR) and Basis of Design (BOD) The Owner s Project Requirements (OPR) documents the functional requirements of a project and the building use and operation as it relates to systems being commissioned. The document describes the physical and functional building characteristics desired by the owner and establishes performance and acceptance criteria. The Basis of Design (BOD) describes the building systems to be commissioned and outlines design assumptions not indicated in the design documents. The design team develops the BOD to describe how the building systems design meets the Owner s Project Requirements (OPR), and why the systems were selected. The BOD will include the Sequence of Operations (SOO) for each of the system to be commissioned. The development of the OPR and BOD are the responsibility of the Owner, Project Architect and the Design Engineer(s). American Commissioning Group will review these documents in order to comply with the applicable Cx requirements. Task 3 Preparation of Commissioning Plan American Commissioning Group will develop a commissioning plan to document how the project will be commissioned. The Commissioning Plan shall include the following: General project information Commissioning goals Commissioning team contact Information and responsibilities Commissioning communication protocols Listing of components and systems to be commissioned Description and listing of the testing Copies of Component start-up and installation check sheets Commissioning Schedule Construction Document (CD) Phase Task 4 - Preparation of Cx Specifications American Commissioning Group will review the drawings/specs where they describe commissioning measures or requirements. We will provide input to the design team to insure the following are addressed: Specific testing requirements by system Facility staff training requirements (if any) O&M manual review and approval procedures System s manual development requirements
