GRIMMER CONSTRUCTION INC

Grimmer Construction Inc. specializes in the design and construction of critical water and sewer infrastructure, with deep expertise in water main replacement, force main alignment, stormwater improvements, and fire service tie-ins. The company executes complex civil works under U.S. Army Corps of Engineers contracts, demonstrating proficiency in trenching, pipe installation, hydraulic system integration, and utility coordination within constrained urban and military-adjacent environments. Their technical capabilities include compliance with USACE design standards, excavation safety protocols, and environmental mitigation measures for sensitive aquatic and floodplain areas. Grimmer’s focus on mission-critical infrastructure for defense installations underscores a proven ability to deliver high-integrity systems under strict regulatory and operational timelines. The contractor maintains a consistent relationship with the Department of Defense, primarily serving through USACE acquisition channels. Their work supports military base resilience initiatives, including potable water system upgrades, wastewater conveyance enhancements, and stormwater management at installations across the Midwest. These engagements reflect a trusted partnership built on reliable execution of federally funded civil works projects, often in coordination with local municipalities and federal environmental oversight bodies. Grimmer Construction’s primary industry focus is NAICS 237110—Water and Sewer Line and Related Structures Construction—positioning them as a specialized civil contractor in public utility infrastructure. They concentrate on subsurface utility systems critical to community and defense readiness, avoiding broader construction sectors to maintain technical precision in water distribution and drainage networks. As a small business structured as a 2L entity based in Highland, Indiana, Grimmer Construction operates with a regional footprint centered on the Great Lakes corridor. While lacking formal government certifications, their consistent performance on USACE contracts demonstrates institutional knowledge of federal procurement processes and infrastructure standards. Their geographic proximity to key military installations enhances responsiveness and logistical efficiency for time-sensitive projects.
