For our project, three separate commissioning authorities have been engaged to oversee the commissioning process; Contractor's Commissioning Specialist (CSC), Designer's Commissioning Specialist (CSD) and the Government's Commissioning Specialist (CSG). The project is very large (over $800 Million in construction cost) so the owner felt expertise in all three corners would be recommended. The CSD, retained by the Architect/Engineer has been involved with development of the original commissioning plan and commissioning specifications with the A/E and the Owner. They have provided commissioning related design document reviews for the A/E throughout all design phases, they will review selected contractor submittals applicable to systems being commissioned, they will review construction related commissioning submittals, and they will witness selected commissioning functional performance tests. The CSC, retained by the builder will be involved with the development of the final commissioning plan, they will develop all final commissioning forms and test procedures in conjunction with the Contractor and all associated subcontractors, they will coordinate the commissioning throughout the construction process, they will perform all pre-functional inspections and submit completed pre-functional forms, they will coordinate and complete all functional performance tests, they will coordinate and complete the O&M training and they will submit a commissioning record as the completion of the commissioning process. The CSG is essentially responsible for completion of the Fundamental Commissioning tasks. The CSG, has been hired directly by the Government (Owner) and will serve as the third party commissioning entity to perform all tasks required to fulfill the LEED Enhanced Commissioning requirements. They will be involved with design document reviews prior to the mid-construction documents phase and have been involved in the review of the OPR and the BOD as well as providing assistance in the development of the commissioning specifications. They will review selected contractor submittals applicable to systems being commissioned, construction checklists and functional performance test forms. They will witness selected commissioning functional performance tests develop a systems manual and review the building operations with O&M staff and occupants within 10 months after substantial completion. Our inquiry is whether or not the team configuration and assignment of commissioning tasks described above will meet the intent of the Energy and Atmosphere Enhanced Commissioning Credit requirements.
The applicant is requesting confirmation that a commissioning team consisting of a Contractor's Commissioning Specialist, Designer's Commissioning Specialist, and a Government's Commissioning Specialist can satisfy the credit requirements. The team configuration as described, appear to meet the credit requirements. With respect to assignment of commissioning tasks, the CSG (directly hired by Owner) shall have ultimate commissioning responsibility with respect to the project including O&M training and verification. Applicable Internationally.
