3rd Party (Client Side) Building Commissioning Services

The scope objectives of Commissioning Consultant (CC) services are to facilitate and provide documented, 3rd party confirmation that a facility fulfills the functional and performance requirements of the building Owner, occupants, and operators. 

Reaching this goal is facilitated through verifying and documenting the Owner’s criteria for building function, performance, and maintainability;  through confirming the project design documents comply with these criteria; through documenting confirmation that systems are installed, set up and operating in compliance with the Owner requirements and design documents.  In addition, through confirming delivery of training and documentation to facilitate the operation and maintenance personnel in sustaining optimal building performance.  

FPC will lead the commissioning activities in a logical, sequential and efficient manner using industry standard protocols and forms, centralized documentation and clear and regular communications and consultations with all necessary parties.

Ideally, the CC should be contracted during the Schematic Design phase (RIBA Stage 1).  During this phase FPC will work with the Owner to facilitate the development of a comprehensive Owner’s Project Requirements (OPR) document and finalize the scope of the commissioning effort.  

During the Design Development (DD) phase (RIBA Stage 2), FPC will review the Basis of Design (BOD) developed by the design team to ensure its completeness and compliance with the OPR.  FPC will then perform a commissioning design review of the project design documents at or before 50% DD (RIBA Stage 3) to ensure the design complies with the OPR and BOD, and ensure industry standards and best practices are being followed.  FPC will also provide commissioning specifications for the construction documents.

During the Construction Document (CD) phase (RIBA Stage 4) the CC will perform a final, more rigorous design review (typically with a strong focus on controls), as well as verify the recommendations from the DD phase review have been incorporated into the design. 

FPC will be involved in the early stages of construction (RIBA Stage 5) by reviewing and commenting on construction submittals for compliance with commissioning needs.  A detailed Commissioning Plan will be developed and reviewed with the Project Team.  Construction checklists to be completed by the contractors will also be developed.  

As construction progresses, FPC will begin attending and leading commissioning progress meetings and observing construction progress on a periodic basis.  Functional test procedures will be developed and distributed to the project team.  

During the latter stages of construction, FPC will witness systems readiness (pre-startup) checks and systems inspections, observe system startups, and air/water balancing.  During the final stages of construction, FPC will witness functional tests performed by the contractors. 

Throughout the construction phases, FPC will document all issues and anomalies noted, and work with the design and contracting team (and the Owner as needed) to resolve commissioning issues.  

Occupancy (Warranty) phase (RIBA Stage 7) tasks will include seasonal testing; analysis of trend data to confirm proper system operation; interview operators and building managers to confirm building performance; assist in resolving open issues carried over from the construction phase.  

Throughout all phases of commissioning, FPC will keep the Owner fully informed of all ongoing commissioning related activities, progress, and issues.
