CD-3, Approve Start of Construction/Execution
CD-3, Approve Start of Construction/Execution
CD-3 is a continuation of the execution phase, and is approved when the project is ready to complete all construction, implementation, procurement, fabrication, acceptance and turnover activities.
It may be necessary to obtain CD-3 approval early for some aspects of a project, namely CD-3A (B, etc), for long-lead item procurement. When exercising long-lead procurement, consider design maturity and the associated project risk. This is the only instance when a CD action may be taken out of sequence (i.e., CD-3A in advance of CD-2). CD-3x justification form and criteria document can be found here.
