About Weston & Sampson Engineers, Inc.

Weston & Sampson Engineers, Inc., doing business as Weston & Sampson, is a multidisciplinary consulting firm based in Reading, Massachusetts, that has been registered to receive federal awards since April 2002. The firm specializes in architecture, engineering design, environmental services, and facilities consulting for both government and private sector clients throughout the East Coast. As a for-profit subchapter S corporation, Weston & Sampson provides comprehensive professional services spanning civil engineering, electrical systems design, HVAC improvements, water and wastewater systems, utility infrastructure assessments, environmental remediation, and climate resilience planning. The company has developed substantial expertise supporting Department of the Navy facilities modernization and infrastructure sustainment initiatives.

Through federal contract awards, Weston & Sampson has delivered diverse engineering and architectural services, demonstrating particular strength in Navy facilities work. The company has executed major delivery orders under its primary indefinite delivery/indefinite quantity contract with Naval Facilities Engineering Command, including a $23.9 million full design services engagement for power reliability and water resiliency upgrades at Portsmouth Naval Shipyard (awarded July 2025), a $7.87 million preliminary design delivery order for electrical and water system upgrades at Portsmouth Naval Shipyard (awarded September 2023), and a $3.92 million Type A and B architect-engineer services award for fiscal year 2023 maintenance and construction power plan activities (awarded June 2023). Additional significant delivery orders have addressed specialized facilities work including a $719,943 modernization and master planning engagement for Building 72 at Naval Prison Camp Kittery (September 2025), a $379,530 NSA mechanical substation relocation study in Mechanicsburg, Pennsylvania (September 2025), and a $2.83 million HVAC and electrical upgrades project (April 2023). The firm has also provided environmental remediation and decommissioning services at Federal Aviation Administration sites under Department of Transportation contract vehicles, including work at multiple New England locations. Outside the Navy's preferred contractor relationships, Weston & Sampson received a $310,436 pool filter maintenance and repair contract from Air Force Materiel Command at Hanscom Air Force Base (September 2024), which was set aside for small businesses. The vast majority of Weston & Sampson's contract work has been awarded without set-aside designations, reflecting the firm's competitive positioning in open procurement competitions.

Weston & Sampson has received federal grant sub-awards primarily through state government agencies serving as prime grantees. The firm has provided design services for renewable energy projects under Commonwealth of Massachusetts Department of Conservation and Recreation grants, including design services for wood heating systems at Mt. Greylock Visitors' Center (with a change order for additional work awarded April 2025), Leo J. Martin Clubhouse Building (November 2024), and the maintenance building at Myles Standish State Forest (November 2024). Additionally, Weston & Sampson has been selected as one of several qualified firms under a New Hampshire Department of Environmental Services environmental consulting services contract (August 2023) to provide emergency response to environmental releases of petroleum and hazardous constituents, investigation and remediation of contaminated sites where responsible parties are unknown or unable to perform required work, and site assessment, cleanup planning, and remediation services at brownfields and Department of Defense sites. These grant sub-awards demonstrate the firm's capabilities in environmental consulting and sustainable design practices beyond its primary Navy contracting focus.

Weston & Sampson holds a $70 million single-award indefinite delivery/indefinite quantity contract with Naval Facilities Engineering Command, awarded May 4, 2021, with an ultimate completion date of May 3, 2026. This primary IDV contract provides multi-discipline utility architecture and engineering services to support Navy facilities sustainment across installations in the northeastern United States. The contract serves as the parent vehicle for numerous delivery orders issued by Navy Installations Command and Naval Sea Systems Command, enabling the efficient procurement of professional design and engineering services for critical infrastructure projects. Task orders issued under this IDIQ have encompassed architectural and engineering studies, electrical system design and upgrades, water and power utility assessments, HVAC system improvements, condensate tank replacement design, pump test station design, groundwater monitoring evaluations, flood risk assessments, stormwater management planning, fire protection compliance studies, and climate resilience planning. The breadth and dollar volume of task orders demonstrate sustained Navy confidence in Weston & Sampson's capabilities and positioning as a preferred professional services provider for northeastern U.S. Navy installations.
