SYSTEMS COMMISSIONING: What is it?“A quality focused process forA quality focused process for enhancing the delivery of a project. 

The process focuses on verifying and documenting that the facility and all f it t d bliof its systems and assemblies are 

planned, designed, installed, tested, operated and maintained to meet theoperated and maintained to meet the owner’s project requirements.”
