Our Process

01

Project Scope & Requirements

You explain what you need built, installed, or modified—often supported by drawings, specs, or concepts. The fabrication team asks clarifying questions to fully understand performance requirements, schedule constraints, quality expectations, and site conditions.
02

Estimating & Alignment

The shop evaluates materials, labor, equipment, tolerances, and lead times. You receive a clear estimate outlining cost, scope assumptions, and timeline. Any scope adjustments, value engineering options, or alternates are discussed before final approval.

03

Engineering & Detailing

Shop drawings, fabrication details, or engineering calculations are prepared and submitted for review and approval. Coordination issues are resolved early.
04

Procurement & Scheduling

Materials are ordered and production is scheduled based on the agreed timeline. You receive confirmation of key milestones.

05

Fabrication

Your project is fabricated in the shop using the agreed materials, processes, and quality standards. You may receive progress updates or photos as we work.

06

Quality Control

Finished components are inspected for dimensional accuracy, weld quality, and compliance with drawings and codes.
