About this file

This document is a Design Analysis for the U.S. Coast Guard Base Administrative Facility Construction Project located in Charleston, South Carolina. The project involves developing a new consolidated administrative building within the existing Coast Guard base, approximately 1,200 feet from the main base entry. The facility will be approximately 26,500 square feet, situated on a 3-acre site, and designed to achieve LEED certification.

Key design elements include site grading and drainage strategies, utility connections for water, sewer, electrical, and telecommunications systems, and considerations for environmental restoration. The project involves managing potential contamination issues, with specific requirements for soil and groundwater handling, monitoring well preservation, and compliance with environmental regulations. The design incorporates stormwater management, parking areas, and infrastructure improvements to support the new administrative building. The project appears to be part of a broader Base Realignment and Closure (BRAC) initiative, with multiple exhibits detailing site plans, environmental assessments, and technical specifications for the construction and site development.

Hobson Ave, Dyess Ave, Brumby Street, Halsey Street

United States Coast Guard (USCG)

Development of new Consolidated Administration Building and infrastructure improvements at Base Charleston for the USCG. The development is located approximately 1,200 feet east of the main base entry gate within the 76-acre Base Parcel A. The new 26,500 SFT building footprint is sited within the southeast corner of S. Hobson Avenue and Brumby Street. The building will be a pile supported structure with concrete pilings to be driven into the ground 80-120'. The site plan includes a surface parking lot and utilities to support building operations as shown on the 35% design development drawings Exhibit A. Excavation on site will be limited to minimum required to install underground utilities; surface drainage will be routed around the building using shallow grass swales connected to new storm drain piping to be installed along S. Hobson Ave. A new storm outfall will be installed from S. Hobson Ave. in the existing bulkhead adjacent to Pier N. Work has been planned to limit potential impacts to known areas of contamination in Exhibit B. The project scope narrative is provided in Exhibit C. Work will require closure of three existing monitoring wells on site following SC DHEC requirements.

EXHIBIT A: 35% DESIGN SITE PLANS (DEMOLITION, BUILDING AND SITE IMPROVEMENTS, GRADING AND DRAINAGE, UTILITIES).

EXHIBIT B: CURRENT NAVY BRAC ENVIRONMENTAL RESTORATION/RCRA PART B SITE INVENTORY EXHIBIT C: 35% BASIS OF DESIGN (SCOPE OF WORK) NARRATIVE AND DRAFT ENVIRONMENTAL PROTECTION PLAN
