Design Change Log.xlsx

This is a Design Change Log template intended to document and track all design changes and their associated cost impacts throughout the design submission phase of a federal construction project. The form serves as a summary document that must accompany each design estimate submission and is specifically required when changes result in contractual modifications. The Design Based Consultant (DBC) submits this log for the CMS Headquarters Roofs & Elevators Project, a design-build contract for roof renovation (approximately 300,000 sq ft) and elevator replacement across multiple buildings at the CMS facility in Woodlawn, Maryland. The estimated project value is $20–$25 million with a 450-day completion timeline.

The template requires documentation of each proposed change including: a short change name, general scope classification (such as HVAC), and total cost impact. For each design change sheet, contractors must provide the change name, scope description, total cost impact, and the specific source directing the change. Additionally, contractors must submit a detailed narrative explaining the exact nature of the change, including quantity adjustments and scope modifications with a separate estimate breakdown for GSA verification. Critically, contractors must justify why each item constitutes a change rather than standard design development, supporting GSA's evaluation of the change's validity and necessity. The template permits DBC use of alternative forms provided the minimum information specified is included.
