Study Notes
Commissioning
- Commissioning is a process that ensures building systems perform according to design intent and owner's needs.
- It is distinct from project takeover which occurs when construction nears completion.
- It is often conducted by a third-party commissioning agent.
- Starts early in the project and continues until occupancy.
- Verifies performance of building components, operation sequences, and mechanical/electrical systems.
Post-Occupancy Evaluation
- Evaluates the performance of completed buildings.
- Conducted at regular intervals.
- May examine technical performance of systems or functional performance of building layout.
- Evaluates the effectiveness of the architect's in-house procedures.
- Records project information for future reference.
- May be required by green building rating systems.
Takeover
- Procedures are required for the orderly transfer of a building project from contractor to owner.
- Protects the interests of the owner, contractor, and architect.
- Requires familiarity with lien legislation in the project's jurisdiction.
Ready for Takeover
- Occurs when a project is substantially complete, defined by a list of factors established by CCDC.
- CCDC 2 2020 defines these factors as prerequisites to attaining Ready-for-Takeover:
- Consultant verification of substantial performance.
- Compliance with occupancy requirements.
- Final cleaning and waste removal.
- Delivery of operations, maintenance documents.
- As-built drawings.
- Startup and testing necessary for occupancy.
- Access to the work provided for the owner.
- Scheduled demonstration and training.
Substantial Performance
- A contractor's deliverable defined by project specifications and construction contract.
- Requires a list of incomplete items submitted to the consultant for review.
- May involve early release of holdback related to a subcontractor's work under CCDC conditions.
Occupancy
- Typically occurs in three situations:
- Unconditional Occupancy: Issued after scope of work is compliant with building codes and building permit.
- Conditional Occupancy: Issued when the building is safe enough for partial occupancy but not fully complete according to construction documents.
- Phased (or Partial) Occupancy: Issued to allow occupancy of a completed portion of a building while construction continues.
Additional Services
- Architects may provide additional services for phased occupancies.
- These services are justified and should be clearly stated in the owner-architect agreement.
Commissioning
- A process transforming facility design into a fully operating system.
- It is a quality assurance process that:
- Begins with defining design intent and ends with building delivery.
- Confirms the contractor's implementation of the architect's design.
- Confirms the ability of the architect's design to meet the client's requirements.
- Addresses any shortcomings.
- A valuable resource for commissioning is Natural Resources Canada's website.
