Heavy Civil & Substation Construction Service Areas
Enterprise Infrastructure Solutions Across the Southwest and Nationwide.
Multi-State Capabilities Grounded in Integrity and Compliance
Headquartered in Navasota, Texas, D. Grimm, Inc. provides full-service heavy civil construction, advanced foundation drilling, and specialized land development for high-voltage energy, utility, and industrial infrastructure projects across the United States. Employing a specialized workforce of 85 to 100 skilled personnel, we partner directly with tier-one EPC firms, prime contractors, and regional utilities to deliver complex scopes ranging from $200,000 to $3.5 million with absolute operational consistency.
We have extensive experience supporting infrastructure projects throughout Texas, Arizona, and New Mexico, including work in major metropolitan and regional growth areas. We understand the workings of areas such as Houston, Dallas/Fort Worth, Phoenix, Tucson, Albuquerque, and Santa Fe.
Empowering Diversity in Infrastructure Projects
As a certified Women-Owned Business Enterprise (WBE) and Historically Underutilized Business (HUB), we are dedicated to assisting corporate procurement teams in effortlessly meeting federal and enterprise diversity requirements. Our commitment extends beyond compliance; we actively participate in a registered government apprenticeship program, ensuring our multi-state field crews adhere to the Davis-Bacon prevailing wage regulations essential for federal Inflation Reduction Act (IRA) infrastructure projects. This dedication to diversity and regulatory compliance underscores our role as a leader in the civil construction industry, driving innovation and excellence across the United States.
Where D.Grimm Operates
Core Regional Operating Hubs
Our teams possess deep regional expertise, heavy-duty equipment fleets (including high-performance Komatsu PC360 excavators), and specialized drilling rigs capable of conquering the most hostile geological and climatic environments in the Southwest.
Texas Civil Construction Footprint
Serving major energy and industrial corridors across Houston, Dallas/Fort Worth, Austin, San Antonio, and the Gulf Coast. Our Texas teams are highly experienced in mitigating the volumetric stress of Central Texas black gumbo clay and handling complex coastal site preparation.
Arizona Civil Construction Footprint
Supporting substation developments, linear utility corridors, and renewable energy grids across Phoenix, Tucson, Mesa, and Flagstaff. Our Arizona crews specialize in deep foundation rock drilling through caliche and basalt, alongside managing strict Maricopa County dust controls and extreme summer concrete thermal tracking.
New Mexico Civil Construction Footprint
Delivering turnkey site preparation and drilled shaft foundations across Albuquerque, Santa Fe, Las Cruces, and Roswell. We regularly navigate remote desert logistics, high-resistivity soil grounding, and strict Bureau of Land Management (BLM) right-of-way stipulations.
Nationwide Travel Capabilities
While Arizona, New Mexico, and Texas represent our primary logistical anchors, D. Grimm’s operational wheelhouse extends across an active multi-state footprint. We maintain active licensing, regulatory compliance, and localized expertise in surrounding states, including Oklahoma, Arkansas, Louisiana, and Mississippi.
Large-scale utility and linear transmission line projects frequently cross state boundaries, requiring a civil contractor capable of rapid, seamless multi-jurisdictional mobilization. D. Grimm is fully equipped to travel nationwide for enterprise-scale projects. Our corporate administrative team directly coordinates all out-of-state environmental compliances, state-specific permitting, and local water quality mandates, shielding prime contractors from localized regulatory liabilities.
