JOHN J BRENNAN CONSTRUCTION CO INC

John J Brennan Construction Co Inc specializes in civil infrastructure construction, with core capabilities centered on public works projects under NAICS 237110, which encompasses heavy and civil engineering construction. The company delivers turnkey solutions for transportation, water conveyance, and site development systems, leveraging expertise in earthwork, grading, utility relocation, stormwater management, and concrete structural placement. Their technical approach emphasizes precision in earthmoving operations, compaction control, and adherence to DOT and federal civil engineering standards. While no specific project examples are available, their classification suggests a focus on durable, large-scale infrastructure requiring compliance with federal and state specifications for safety, environmental mitigation, and material testing. Their operational model likely integrates surveying, heavy equipment deployment, and subsurface utility coordination to support public infrastructure lifecycles. No agency relationships can be identified from available award data, and no recent contract awards are documented to infer specific customer partnerships or recurring project types. Consequently, there is no evidence of established relationships with federal, state, or local entities. The contractor’s primary industry focus is heavy and civil engineering construction, which involves the building of non-building infrastructure such as roads, bridges, dams, tunnels, and water and sewer systems. This places them in the public works sector, serving as a contractor for municipally funded or federally assisted civil projects requiring specialized heavy machinery and civil engineering oversight. The company is structured as a small business (2L classification) and is headquartered in Shelton, Connecticut. It holds no active government certifications such as 8(a), HUBZone, or WOSB. Its geographic presence is localized to the Northeast, with operations likely centered on regional infrastructure initiatives. The firm positions itself as a regional player in civil construction, relying on technical execution and local market familiarity rather than federal certification advantages.
