Section 01 — Capabilities

What we build

Three scopes, one contractor. The same crews that build generator sites for carriers build your EV chargers and fiber pathways — to the same standard.

Backup Power

When the grid drops, your site doesn't. Generator sets, transfer switches, and DC plants — installed, commissioned, and load-tested with the reports to prove it.

  • BP-01Generator install & commissioning
  • BP-02Automatic transfer switches
  • BP-03Load bank testing & documentation
  • BP-04AC/DC power systems
Full scope

EV Infrastructure

Trench, conduit, panel upgrade, charger, energization — the whole chain under one license. Fewer subs on your site means fewer change orders on your desk.

  • EV-01Level 2 & DC fast charger install
  • EV-02Panel & service upgrades
  • EV-03Trenching, conduit & wire pulls
  • EV-04Utility coordination & energization
Full scope

Telecom + Fiber

Where JMES started. Fiber pathways, grounding, and in-building systems built to carrier standards — labeled, tested, and documented like the network depends on it.

  • TF-01Fiber to site & splicing
  • TF-02Grounding & bonding systems
  • TF-03IBS modernization
  • TF-04Microwave ground work

Proof, not promises

Straight from our job sites — no stock photos, no renders. What we build is the portfolio.

Section 03 — How we work

No surprises. By design.

The process is boring on purpose. Clear scope going in, complete documentation coming out.

STEP / 01

Walk the site

We look before we bid. Site assessment, load calcs, utility constraints — the stuff that becomes a change order when it's skipped.

STEP / 02

Scope it straight

Real numbers and a real schedule. What's included is written down; what's excluded is written down too.

STEP / 03

Build it right

Self-perform crews, code-first workmanship, daily communication. If something moves, you hear it from us first.

STEP / 04

Energize & close out

Load tests, ground readings, redlines, photo documentation — a closeout package you don't have to chase.

Section 04 — Who we work with

Built for the people on the hook

Our clients answer to networks, tenants, and fleets. Every job ships with carrier-grade documentation — because that's where we come from.

Telecom carriers & turf vendors

Generator programs, site power, grounding, and fiber built to carrier specs — with the closeout to match.

General contractors

A sub that answers the phone, hits dates, and holds a B + C-10 — so one award covers the whole electrical scope.

Property owners & managers

EV charging, service upgrades, and backup power for commercial and multi-family sites — permitted and inspected.

Fleet & EV operators

Depot charging from load study to energization, coordinated directly with the utility.
