Normal subcontractor testing can often be performed in coordination with commissioning.  Proper coordination of these activities can reduce total commissioning time and reduce system problems. The commissioning process may require additional coordination time for subcontractors, which can result in additional contract costs. During the construction team bidding phase, include Cx coordination (at a minimum) in the scope of the mechanical, electrical and controls subcontractors.
