It is recommended that the CxA is contracted according to a two phase fee
negotiation process. The first phase includes Design Stage responsibilities and
the second phase includes Construction and Post-Construction activities. This
two phase process allows for the negotiation of the initial fee to be based on known
general factors, and negotiation of the Construction and Post-Construction Stage
fee based upon a substantially completed design and the actual type and number
of equipment, systems and assemblies to be inspected, started and tested.
Incorporate Commissioning into
Within the Design Stage proposal, the CxA shall be asked to provide budgetary
