Bottom LineCommissioning benefits all parties

involved in the design, construction and operation of new and existing building.

From the building owner or developer’s perspective, it is a win-win proposition.

What is needed to make commissioning happen?Owner/developer must make a conscious decision to include commissioning – and make it a project requirementA knowledgeable architect, engineer or commissioning agency can make the owner aware of the benefits of commissioning

Commissioning is a Team Effort

Commissioning succeeds when:Every team member understands and carries out their responsibilitiesEvery team member cooperates and coordinates with each other and third-party agencies

Communication and accountability are the keys to teamwork – and they are the responsibility of the commissioning agent.
