About this file

This document is an amendment (Amendment 0004) to a federal contract solicitation for design-build services for utility infrastructure, roads, and a clinic at the United States Coast Guard (USCG) Base in Charleston, South Carolina. The amendment extends the proposal due date from September 3, 2025, to October 17, 2025, at 2:00 pm Eastern Daylight Time, and makes several key specification changes.

The primary modifications include updating sea level rise calculations from the U.S. Army Corps of Engineers to NOAA's Sea Level Rise Calculator, adjusting flood design class requirements, revising generator fuel supply guidance, and updating various technical specifications for the project. The solicitation covers design and construction of a medical/dental clinic, guardhouse/visitor center, access control point, and related infrastructure, with specific requirements for environmental compliance, sustainable design, and adherence to various federal building standards. The project involves significant site work on a brownfield location, requiring careful environmental and technical considerations.
