How We Work

Our Execution Process

01

Site Survey

We visit the site, study the single-line diagram and confirm load, routing and shutdown constraints.

02

Scope & Schedule

A written scope, bill of material and a dated schedule built around your shutdown window.

03

Execution

Our own crews under a dedicated site engineer, with documented permits and PPE discipline.

04

Testing & Handover

Megger, IR, contact resistance and injection tests recorded and submitted before charging.
