Natural Gas Infrastructure

NEUCO serves gas utilities by providing natural gas polyethylene, steel, and networked geothermal piping installations. Our construction capabilities include trenchless technologies like horizontal directional drilling (HDD).

Piles of dirt and orange traffic cones surround the trench.

Underground Infrastructure

Excavation, trenching, shoring, backfill, and other civil works that install or integrate gas, electric, and water scopes.

Specialized Offerings That Set Us Apart

Complex corridors and dense streets demand methods that reduce risk, shorten schedules, and keep communities moving. These specialty capabilities are how we deliver cleaner work zones, fewer conflicts, and better project economics.

  • Horizontal directional drilling (HDD): Trenchless crossings under roads, rail, and waterways to avoid surface disruption.
  • Vacuum excavation: Non‑destructive verification of underground utilities depth and alignment before excavation or HDD. Reduces third‑party damages and accelerates permit approvals by proving separation tolerances.
  • Cast‑iron encapsulation (LP & IP): Permanent joint repairs that extend the life of legacy pipe and reduce methane‑leak risk where full replacement is not immediately practical.
  • Saw-cutting & trench grinding: These surface preparation techniques, used during excavation, control edges, depths, and patch geometry, delivering safer work zones and minimal disruption

New England Reach & Dispatch Efficiency

With headquarters in Lawrence, Massachusetts, and locations in Maine and New Hampshire, we mobilize quickly across the region. A fully automated dispatch system coordinates people, equipment, and materials so work packages hit the street with the right crews, permits, and sequence. That means faster restoration times and clearer communication with municipalities and abutters.

Safety & Quality—The Right Way, Every Day

Safety is a core value. Our crews complete live-gas, OSHA, and HAZWOPER courses, as well as training in confined-space entry, hydraulic-tool operation, CPR, and First Aid, in addition to welder qualifications, which bolsters safety. In addition, we run a robust QA/QC program that focuses on procedure adherence, weld documentation, pressure-test records, restoration verification, and performance tracking (including non-injury rates, third-party damage, and actual vs. planned productivity) to drive continuous improvement.

Infrastructure for the Future

Utilities are accelerating grid and gas modernization, methane reduction, and decarbonization. Future-proofing New England’s energy systems is already part of NEUCO’s day-to-day operations. Our programs accelerate methane reduction by replacing leak‑prone cast iron and unprotected steel with modern HDPE and protected steel. We also assist electric distribution utilities in hardening their electric network through civil delivery for new duct banks and structures.

Our Track Record

NEUCO has demonstrated its capabilities through several completed gas and infrastructure projects.

  • Portland, ME, Unitil SURE Project: Over a 14‑year modernization program, NEUCO served as a primary contractor helping replace and upgrade more than 100 miles of cast‑iron and unprotected steel with high‑density plastic. The program also upgraded 8,862 service lines and 16,945 meters to improve reliability and enable higher‑pressure operation where needed (Unitil, 2024). On one representative segment, our crews replaced 60,587 feet of low-pressure, leak-prone main with intermediate-pressure HDPE while navigating complex traffic, historic streets, and multiple stakeholders.
  • Lewiston, ME: A seven‑year, 60‑mile replacement program won on the strength of our service quality and versatility. This project anchored our continuous New England utility construction and demonstrated NEUCO’s ability to scale crews while maintaining quality and safety.
