Visual Weld Inspection (VT)
Code-based visual inspection with clear calls, photos, and weld ID traceability.
Certified Inspections That Keep Your Project on Schedule.
CWI-Grid provides AWS CWI and ICC S1-certified structural steel, weld, and high-strength bolting inspections for general contractors, EPC firms, and data center developers who can't afford delays or failed audits. We deliver clear documentation, meet your spec requirements, and mobilize when your project needs us — not when it's convenient for us.
Starting at $120/hr for standard single-inspector engagements. Travel, mobilization, and multi-phase projects are scoped separately — request a quote and we'll respond the same business day.
Dual-Certified Inspectors
AWS CWI + ICC S1 — the credentials your project specs and AHJs require, held by our inspectors, not borrowed.
Most Projects Mobilize Within 24–48 Hours
Built for active construction timelines, data center phased builds, and pipeline programs that can't wait.
Data Center & Pipeline Specialists
Structural steel, high-strength bolt-up, and pipeline weld inspection — industries where a missed checkpoint means real schedule risk.
Welding & Structural Inspection Services
AWS CWI and ICC S1-certified inspection for structural steel, pipeline welds, and high-strength bolting — with hold point documentation your AHJ will accept and your PM can actually track.
