A. Attention is directed to the CONTRACT AND GENERAL CONDITIONS and all Sections within DIVISION 01 - GENERAL REQUIREMENTS, which are hereby made a part of this Section of the Specifications.

1.2 DESCRIPTION OF WORK

A. Commissioning: Commissioning is a planned, collaborative process of witnessing and testing that confirms that a new building and its systems meet the Owner’s Project Requirements (OPR) and the project’s Basis of Design (BOD). The OPR is a written document that details the ideas, concepts and criteria that are defined by the owner to be important to the success of the project. The BOD includes design information necessary to accomplish the OPR, including system descriptions, indoor environmental quality criteria, design assumptions, and references to applicable codes, standards, regulations and guidelines. Achievement of these goals begins in the Pre-Design phase, continues through the Design, Construction and Acceptance Phases and concludes in the Post-Acceptance Phase with actual verification of performance.

Commissioning shall encompass and coordinate the traditionally separate functions of system documentation, equipment startup, control system calibration, testing and balancing, performance testing and training. The commissioning process will be directed by an independent, third-party Commissioning Authority (CA) whose services will be provided by

DCAMM.

1. In addition to collaborating in the development of the project’s BOD and OPR, during the Pre-Design Phase the Commissioning Authority shall review the size and skill levels of the Owner’s maintenance staff in relation to the requirements of the new building in order to fill any deficiencies.

2. In the Design Phase the Commissioning Authority shall complete the following tasks:

a. Write commissioning specifications that define contractor responsibilities and provide samples of required commissioning documentation (based on the most recent industry-accepted format) to the Designer for integration into the project specifications.

b. Develop the Commissioning Plan, detailing commissioning team organization, schedule, training and documentation requirements. Include all related testing, verification and quality control procedures.

c. Establish the schedule for all commissioning activities, including periodic design reviews. Insure that commissioning activities do not interfere with any phase of the project.

d. Review the design calculations and performance criteria for the project, identifying operation and maintenance problems. Provide written comments and a checklist of required actions to be completed by the Designer prior to phase approval and recommend alternatives where appropriate.

e. Check and confirm that the BOD includes all of the elements defined in the OPR at the end of the Design Phase.

3. In the Construction Phase the Commissioning Authority shall complete the following tasks:

a. Update the Commissioning Plan to reflect any changes in the BOD.

018100 - 3

f. Document testing and balancing work.

4. In the Acceptance Phase the Commissioning Authority shall complete the following tasks:

a. Monitor and document functional performance tests on all building systems in collaboration with the Project Team.

b. Review O&M documentation and develop O&M training plans and videos. Ensure that the Owner’s staff is able to operate and maintain all building systems.

c. Review all as-built documents and warranty information in collaboration with the

Project Team. Submit warranty information and preventive maintenance schedules for all building systems in a comprehensive, five-year preventive maintenance plan. The format for this submittal shall be approved jointly by DCAMM and the Owner. This submittal shall also include list(s) of recommended spare parts, bench stock and special tools/equipment required for the first year of building operation.

d. Convene and chair a comprehensive final debriefing with the entire Project Team (including the owner’s maintenance staff) to coordinate correction of any required re-testing and identification of any training deficiencies prior to building turnover.

e. In collaboration with the Designer, Contractor(s) and General Contractor populate all operational information, including equipment data, for each building system in the digital format specified by DCAMM.

5. In the Post-Acceptance Phase the Commissioning Authority shall complete the following tasks:

a. Coordinate with the project team to ensure that any required “off-season” tests are completed.

b. Ensure that any required changes are provided as written updates in the project documentation.

c. Confirm that all equipment continues to perform as designed and alert the Owner to any warranty claims by providing a review of all system warranties prior to their one-year expiration date.

d. Document the estimated savings generated by the commissioning process through specific examples of avoided costs collected during all project phases. The required format will be provided by DCAMM. Compare the actual tested performance of the building’s completed systems with established standards.

e. Implement a measurement and verification (M&V) plan consistent with Option D:

Energy Conservation Measure Isolation as specified in the International Performance Measurement & Verification Protocol (IPMVP) Volume III:

Concepts and Options for Determining Energy Savings in New Construction, April, 2003. The M&V period must cover at least one year of post-construction occupancy.
