Services
Typical industrial structural work — practical scopes, clear assumptions, buildable deliverables.
Pipe racks & supports
Pipe racks, utility supports, and attachments coordinated with mechanical and construction constraints.
Building expansions
Additions, framing modifications, and structural support for growing industrial facilities.
Inspections & assessments
Condition assessments, strengthening recommendations, and adaptation of existing structures.
Hoist & equipment structures
Overhead hoist runways, equipment supports, and foundations — part of the broader industrial practice.
Calcs, drawings & sealing
Calculation packages and drawing sets from sketches and redlines — QC’d, then sealed under PE responsible charge.
Approach
From field sketch to sealed set — with PE judgment at every gate that matters.
- 01
Intake
Share sketches, photos, loads, and constraints. We clarify scope, code basis, and deliverables before work starts.
- 02
Preliminary calculations
Design criteria, loads, load path, member sizing, and assumptions — documented for your review.
- 03
Drawings
Constructible plans, sections, and details developed from your markups and site realities.
- 04
Independent QC
Internal check of assumptions, units, and completeness before the PE seal review.
