BIG's source inspection services verify the quality of pumps, valves, pressure equipment, and steel fabrications at the vendor's facility before they ship to the job site. Our procurement team sources steel, piping, electrical, fasteners, pumps, valves, and fittings for EPC construction projects in the Houston and Gulf Coast region.
A defective pump discovered at the vendor's shop is a procurement delay. The same defective pump discovered during construction is a schedule disaster. Source inspection eliminates this risk by verifying that materials and equipment meet specifications before they leave the manufacturer's facility.
BIG's source inspection process begins at the project kick-off meeting, where we coordinate with the vendor and project team to establish surveillance points, hold points, and witness points. This ensures inspection activities are built into the vendor's production schedule — not bolted on as an afterthought. Our inspectors then witness manufacturing processes, review material test reports (MTRs), perform dimensional verification, and observe factory acceptance tests (FATs). We provide the owner or EPC with documented assurance that what they ordered is what they're getting.
Beyond inspection, BIG serves as a procurement specialist for EPC construction projects. We leverage established vendor relationships to source materials competitively with full traceability and documentation.
Structural steel, platforms, pipe racks, equipment supports
Piping design, fabrication, carbon steel, alloy, stainless
Cable tray, conduit, wire, panels, switchgear
Bolting, studs, nuts, gaskets — all material grades
Centrifugal, positive displacement, metering pumps
Gate, globe, ball, check, butterfly, and all pipe fittings
Vendor qualification: BIG audits and pre-qualifies fabrication shops and material suppliers to ensure they meet project quality requirements before procurement begins.
Source inspection is most effective when it's planned from the start — not called in when a problem surfaces. Here's how BIG integrates into the procurement lifecycle:
Why this matters: Establishing hold points at kick-off prevents the most common source inspection failure — showing up at the vendor and discovering that critical work was already completed without inspection witness.
Source inspection is the process of inspecting materials, equipment, and fabricated components at the vendor's or manufacturer's facility before they ship to the job site. This catches defects at the source rather than discovering them during construction, preventing costly delays and rework.
BIG inspects pumps, valves, pressure vessels, heat exchangers, piping spools, structural steel fabrications, electrical equipment, and other engineered components. We witness factory acceptance tests (FATs), hydrostatic tests, and performance tests.
BIG acts as a procurement specialist, leveraging vendor relationships to source materials competitively for EPC projects. Our procurement specialties include steel fabrication, piping design and fabrication, electrical components, fasteners, pumps, valves, and fittings. We provide material on a cost-plus-margin basis with full traceability.
Yes. Source inspections are conducted at vendor facilities wherever they are located — domestically and internationally. Travel expenses are billed separately from the inspection fee.
Each source inspection includes a detailed inspection report with findings, dimensional verification records, material test report (MTR) verification, photos, and a pass/fail disposition. Reports are delivered within 24-48 hours of the inspection.
