Contract Modifications

Contracting Officer (CO), Contracting Officer Representative (COR) Construction Management Representative (CMR), or Project Manager (PM)

• Identify potential changes through discussions with COR, Construction Contractor, Suppliers, Designers, Park Staff, and other appropriate sources.
• Research potential change to determine if change qualifies as a modification and gain concurrence from COR.
• Determine if potential change will impact project schedule.
• Attach required drawings, specifications, and related information. Submit to the COR and CO for review. The CO will issue the Request for Proposal (RFP). Track RFP status with NPS project management and communication software.
• Prepare Modification Estimate of Cost (CM-5). Forward to COR for review.
• Forward comments on time impacts and recommendation for time extension (change must affect critical path) to COR for review. Consider time impacts when preparing independent Government estimate.
• Use Architect-Engineer (A/E) Designer, as needed, for assistance in pricing unique, highly technical, or complex materials or equipment. Coordinate use and authorization with COR.
• Prepare and forward modification package to COR. (Attach required drawings, specifications and related attachments.)
• Include the following backup:
  • CO Directives
