INFORMATIVE APPENDIX J OWNER’S PROJECT REQUIREMENTS
This appendix provides an example of how to implement part of Guideline 0. It is not intended to be a comprehensive representation or a best-practice example. Practitioners applying the Cx should carefully follow Guideline 0 and applicable commissioning technical guidelines tailored to their specific projects.
A general format for an OPR document is presented in this appendix. The structure provided is intended to encompass the facility requirements and enable the addition of sections, depending on the systems and assemblies to be constructed.
a. Introduction —Includes an overview of the project and
the general reasons why the project is being undertaken. A description of the Owner’s processes (Cx) is typically contained in this section. b. Key OPR Items —Includes a listing of the key OPR that
the Cx will focus on and that the Owner (CxP Team) has determined are critical to the success of the project. c. General Project Description —The size and scope of the
project are included in this section. d. Objectives —The objectives for accomplishing this proj ect are detailed in this section. e. Functional Uses —The expected functional uses (spaces)
for the facility are detailed in this section. A short description of each functional use is included to provide the context in which it was detailed.
f. Occupancy Requirements— Includes the number of occupants (users and visitors) and the schedule of occupancy, including all special conditions. g. Budget Considerations and Limitations— The expected
budgetary restrictions and considerations are contained in this section. h. Performance Criteria— The performance criteria on
which the project will be evaluated by the CxP Team are included in this section. Each performance criterion should be measurable and verifiable. Include the following subsections as appropriate to organize and explain the criteria:
- General
- Economic
- User requirements
- Construction process
- Operations
- Systems
- Assemblies i. OPR Version History— Includes a summary of the changes made throughout the Predesign Phase, Design Phase, Construction Phase, and Occupancy and Operations Phase. This information is critical to understand and document the trade-offs made over time and the resulting impact on the project.
Table J-1 will assist in the development of the OPR document in accordance with Section 5.2.2.4 using the format presented in this appendix. The table is also applicable for those developing technical supporting guidelines as described in Normative Appendix A. Inclusion of specific criteria (such as the entries in this example matrix) will depend on the project and the Owner’s needs. The “Key OPR” section should emphasize those OPR items that are essential to the success of the project.
