PMT|SITE

Acquired 2025 · Read announcement · PMT website

Nashville-based, self-performing earthwork and industrial utility contractor with 15+ years of execution experience across underground utilities, site preparation, and critical infrastructure. Acquired by American Gridwork Partners (AGP) in 2025, PMT delivers full-lifecycle site development — from clearing and excavation through utility installation and drilling & blasting — across residential, commercial, and public infrastructure end-markets.

Core Areas of Focus
Underground Utilities
Water main, sewer, stormwater, gas conduit — full self-perform installation and trenchless construction.
Site Prep & Grading
Clearing, excavation, earthwork, and grading for residential, commercial, and industrial sites.
Emergency Maintenance
Rapid-response crew mobilization for waterline breaks and infrastructure failure — T+30 payment, high margin.
Municipal Infrastructure
Government-aligned utility relocation, stormwater upgrades, and compliance-driven site work.
Sovereign / Alt. Power
Behind-the-meter, datacenter, EV & solar infrastructure.
Strategic Portfolio Fit
Execution Layer Anchor
PMT physically builds the substations, site prep, and underground utilities that hyperscaler and grid modernization projects require — positioning AGP at the most capital-intensive, hard-to-replicate point in the value chain.
Recession-Resilient Cash Flows
Water, sewer, and emergency response work is non-discretionary; T+30 emergency response projects carry higher margins with low customer acquisition cost.
Platform Consolidation Thesis
PMT is the operational core around which AGP adds bolt-on contractors, sharing estimating systems, vendor networks, and back-office infrastructure.
Fragmented Market, Institutional Advantage
Southeast critical infrastructure is dominated by family-owned firms with $5–50M revenue and no institutional scale; AGP's software stack, capital, and M&A capability is structurally differentiated.
