  Independent Third-Party Commissioning Professional— A commissioning consultant contracted directly by the owner who is not responsible to, or affiliated with, any other member of the design and construction team.

  Operation and Maintenance (O&M) Manuals— Documents that provide information necessary for operating and maintaining installed equipment and systems.

  Owner Representative— An individual or entity assigned by the owner to act and sign on the owner’s behalf.

  Process Equipment— Energy-using equipment and components that are not used for HVAC, electrical, plumbing and irrigation operations. Such devices would include but are not limited to heat transfer, water purifying, air cleaning, air vacuum and air compressing.

  Sequence of Operation— A written description of the intended performance and operation of each control element and feature of the equipment and systems.

  Selecting Trained Personnel (for Commissioning)

  This code requires that “Commissioning shall be performed in accordance with this section by trained personnel with experience on projects of comparable size and complexity.” The trained personnel manage and facilitate the commissioning process. The trained personnel develop and implement the commissioning tasks and documentation identified in Sections 5.410.2.1 through 5.410.2.6. Trained personnel may include appropriate members of owner staff, contractor and design team as well as independent commissioning professionals.

  It is essential that there is a single person designated to lead and manage the commissioning activities. In practice, this individual has been referenced by various identifiers such as commissioning authority, agent, provider, coordinator, lead, etc. In this guide the term “commissioning coordinator” is used.

  The designated commissioning coordinator may be an independent, third-party commissioning professional, a project design team member (e.g., engineer or architect), an owner’s engineer or facility staff, contractor or specialty subcontractor. Methods of evaluating the designated commissioning coordinator and trained personnel include review of the following:

  1. Technical knowledge;
  2. Relevant experience;
  3. Potential conflict of interest concerns;
  4. Professional certifications and training;
  5. Communication and organizational skills; and
  6. Reference and sample work products.

  COMPLIANCE FORMS, WORKSHEETS AND REFERENCE MATERIAL

  Selection of “trained,” qualified personnel is required by this code. In order to meet this requirement, the commissioning provider should be evaluated via the methods discussed above. In addition, various organizations have training and certification programs that may be a source for identification of qualified commissioning providers.

  For information about enforcement and compliance of each commissioning element see Sections 5.410.2.1 through 5.410.2.6.

  For compliance forms and templates see Part 2 following this standard.

  Reference: 1 Owner’s Project Requirements

  CALGreen Section 5.410.2.1, Owner’s or Owner representative’s Project Requirements (OPR).

  1.1 Intent:

  The Owner’s Project Requirements (OPR) documents the functional requirements of a project and expectations of 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 OPR is most effective when developed during predesign and used to develop the Basis of Design (BOD) during the design process. The level of detail and complexity of the OPR will vary according to building use, type and systems.

  • Maximum allowable variation in the tile substrate—for tiles with all edges shorter than 15", maximum allowable variation is [1] ⁄ 4 " in 10' from the required plane, with no more than 1 ⁄ 16 " variation in 12" when measured from the high points in

  the surface. For tiles with at least one edge 15" in length, maximum allowable variation is [1] ⁄ 8 " in 10' from the required plane, with no more than [1] ⁄ 16 " variation in 24" when measured from the high points in the surface.

  • Center backer board end or edge joints on framing and stagger joints in adjacent rows so four corners do not come together within the same plane. Space panel ends and edges in accordance with manufacturer’s recommendations.

  Movement Joint (architect must specify type of joint and show location and details on drawings)

  • Movement joints—mandatory according to EJ171.

  • When glass tile is used, adhere to more frequent placement recommendations within the ranges listed in EJ171. Installation Specifications

  • Waterproof membrane—ANSI A108.13.

  • Tile—ANSI A108.5.

  • Glass tile—manufacturer’s directions.

  • Cementitious grout—ANSI A108.10.

  • Epoxy grout—ANSI A108.6.

  • Movement Joints—EJ171 and ASTM C1193.

  Notes

  • Test shower pan membrane/waterproof membrane and drainage fitting for leaks before commencing tilework.

  • Materials adversely affected by moisture in areas immediately adjacent to showers, tubs, and roman tubs should be properly protected.

  • All horizontal surfaces, for example shower seats, sills, curbs, etc., must slope towards drain or other surface sloped toward drain. Where present, waterproofing also must be sloped.

  • When glass tile is used, see “Glass Tile Selection and Installation Guide,” and consult manufacturer for recommendations and requirements.
