"It is important to start the commissioning process in the pre-design phase. This early involvement is critical for the timely and useful development of the Owner's Project Requirements (OPR), the subsequent design team Basis of Design (BOD), the Commissioning Plan, and the beginning of the Operations & Maintenance (O&M) Systems Manual. If these tasks are left until later in the process and "reverse engineered" to match the design, their usefulness as catalysts for dialog, cost and risk management, and quality tracking tools is lost."

It's my understanding that Commissioning begins early on in the design phase and carries through the project. The Contractor plays a part in Commissioning during construction when systems are installed and tested against the Commissioning Plan. See the link above and review the info. It helped me tremendously on CDS. Hope this helped!

Commissioning is listed as an added service because typically they are another consultant that needs to be hired during design. The contract is also presupposing the owner wants to have the Commissioning agent brought on board during the design phase. A good idea for all the reasons noted above. Sometimes Owners carry the contract with the commissioning agent themselves, but the Architect could/would still be entitled to an additional service as it is another entity to manage during the design phase. Some owners wait until construction begins to hire the commissioning agent and at that point, they are more of an on-site QA/QC set of eyes for the MEP systems installation. In that case, I would argue the Architect is not entitled to additional services. Contractors typically do not commission anything in this context... they will however perform startup procedures on specific systems/equipment and are obligated for correctly installing work.
