Construction checklist items are to be completed as part of startup and initial checkout, before functional testing.
· This checklist augments, but is not meant to replace recommendations or requirements for installation, checkout and startup from standards, manufacturers, codes or governing bodies.
· If this form is not used for documenting, a CxP approved form of similar rigor may be used.
· Contractors assigned responsibility for sections of the checklist shall be responsible to see that checklist items by their subcontractors are completed and checked off.
· In the Trade column, indicate the contractor responsible for verifying the completion of this item:
| A/E = architect/engineer | All = all contractors | CxP = commissioning provider |
| CC = controls | EC = electrical | GC = general |
| MC = mechanical | PC = plumbing | SC = sheet metal |
TAB = test and balance CxP Approval This filled-out checklist has been reviewed. Its completion is approved with the exceptions noted below.
