MARK ZIMMER

Mark Zimmer specializes in the design, installation, and replacement of high-capacity industrial and commercial heating systems, with deep expertise in power boilers, heat exchangers, and outdoor-rated boiler units for federal infrastructure. The contractor delivers turnkey solutions that include removal and disposal of legacy equipment, precision piping and plumbing integration, and installation of energy-efficient boiler systems compliant with federal efficiency and safety standards. Technical capabilities span manufacturing and field deployment of steam and hot water systems, with demonstrated proficiency in retrofitting aging facilities—including visitor centers, maritime dormitories, and buoy barges—with modern, durable heating equipment such as Aerco Benchmark models and Fulton boilers. Their work emphasizes operational continuity, thermal efficiency, and adherence to mechanical code requirements under demanding environmental conditions. The contractor has delivered projects for the Department of the Interior, Department of Transportation, Department of Defense, and Department of Homeland Security, consistently supporting mission-critical facilities requiring reliable thermal systems. Work for the Interior includes upgrading visitor center heating in remote locations; for Transportation, it involves marine and campus infrastructure upgrades; for Defense and Homeland Security, it entails robust boiler replacements in high-utilization, often austere environments. These engagements reflect a pattern of trusted execution on geographically dispersed, mission-sensitive installations requiring precision and regulatory compliance. Primary industry focus lies in NAICS 332410 (power boiler and heat exchanger manufacturing) and 333414 (heating equipment manufacturing), with complementary execution under 238220 (plumbing, heating, and air-conditioning contractors). This dual manufacturing-and-installation capability positions the contractor as a vertically integrated provider for federal agencies seeking end-to-end heating system solutions without subcontractor fragmentation. Mark Zimmer operates as a small business under entity structure 2J, with no federal certifications on record. Based in Grant, Michigan, the contractor serves federal clients nationwide, leveraging localized logistics and technical agility to support remote and coastal federal assets. Their market positioning centers on reliable, code-compliant thermal system delivery for mission-critical federal infrastructure.
