Engineering, Procurement & Construction

Engineering, Procurement & Construction (EPC)

GMB delivers utility infrastructure projects on a turnkey basis, carrying a project from design through procurement to a finished, energized asset under a single contract. For utilities and developers, that means one accountable partner for the whole build, and one team answering for schedule, budget, and quality.

Fewer Interfaces, Less Risk

Split a project across a designer, a procurement group, and a builder, and the risk collects in the gaps between them. Design that ignores how the asset gets built. Long-lead equipment that lands late. A field change nobody owns. Traditional delivery multiplies those handoffs, and each one is a chance for the schedule and budget to move.

Turnkey EPC collapses those interfaces into one team. Constructability is considered while the design is still on the table, procurement is timed to the build, and accountability never gets passed around. For a utility running a full program, that is fewer contracts to manage and fewer places for the project to stall.

The Three Disciplines

Design, Supply, Build, One Team

Engineering

Covers: Detailed design, technical specifications, and feasibility, developed with the build in mind.

How we deliver it: How GMB provides engineering: in-house staff, engineering partners, or engineer-of-record on the client side. State this precisely, it is the first thing a utility verifies about an EPC provider.

Procurement

Covers: Sourcing, purchasing, and supply-chain management for equipment and materials, long-lead items included.

Why it matters: When procurement is owned by the same team building the job, long-lead equipment stops driving the critical path.

Construction

Covers: Civil, structures, installation, and commissioning support that produce a finished, operational asset.

Our foundation: This is what GMB does at scale. Self-performed, utility-grade construction backed by crews proven on the most demanding work in the industry.

Civil & Foundations

From Access Road to Energized

A turnkey build has to account for everything it takes to get to the site and stand up the structure, not just the line work at the end. GMB carries that full civil scope inside the same contract and the same schedule.
  • Access roads and grading
  • Right-of-way preparation and clearing
  • Matting for access and ground protection
  • Drilled pier and spread footing foundations
  • Concrete placement
  • Erosion and sediment controls
  • Stormwater management
  • Environmental compliance
  • Site restoration
  • Construction support services

What Turnkey Delivers

You Get an Asset, Not a Project to Manage

One Contract, One Accountability
A single partner answerable for design, supply, construction, schedule, and quality.
Built-In Constructability
The builders are at the table during design, so problems are engineered out instead of discovered in the field.
Predictable Delivery
Procurement timed to construction and progress tracked by work package keep the project on plan.
The Depth of the Groupry
Backed by the C-MAK Energy Group, with self-performed line and civil scope and more than 1,000 deployable resources.
