Design/Build B562 MAU#1 Replacement

The Department of the Navy Naval Facilities Engineering Command is soliciting design-build services for the replacement of two existing Makeup Air Units (MAUs) at Building 562, a Hazardous Waste Management Facility located at Naval Submarine Base New London in Groton, Connecticut. The existing 26-year-old units lack dehumidification capability and require replacement with equipment that maintains 50% relative humidity (±10%) in shipping, receiving, process, and storage areas while incorporating energy efficiency and cost-effectiveness measures. The base contract (CLIN 0001) includes design, provision, and installation of MAU #1 with design only for MAU #2, with a 210-day performance period, and optional contract line items (CLINs 0002-0007) are available for MAU #2 provision and installation, temporary MAU rental, and ductwork services. Evaluation will be conducted on lowest evaluated price including base requirements and any additive bid items under FAR 52.217-5, with options evaluated together with the base bid. The proposal due date is April 29, 2026 at 12:00 PM EST, with previous Request for Information deadlines and proposal amendments extending the timeline from the original March 4, 2026 deadline.

This solicitation uses no set-aside designation and is available only to five pre-qualified Multiple Award Construction Contract (MACC) holders: Addon Services LLC, Armitage SAI JV, Black Horse Construction Group, CCI Facility Support Services LLC, and Doyon Management Services LLC. The estimated construction cost ranges between $250,000 and $500,000 (NAICS code 236220, PSC Y1JZ), with liquidated damages of $271.00 per calendar day for schedule delays. The contractor must complete MAU replacement within two days and all work within 210 calendar days after contract award, with no time extensions permitted regardless of equipment lead times. Prevailing wage requirements apply under Davis-Bacon standards with wage rates established for New London County, Connecticut, and contractors must comply with comprehensive safety, environmental, and security requirements including $500,000 general liability insurance and participation in the Defense Biometric Identification System. Performance will occur at Groton, Connecticut 06349, with mandatory site visits required and contractor responsibility for utility connections, equipment removal, concrete pad management in a PFAS potential release area, and integration with existing building controls systems.
