Structural Steel, Welding, Bolting, NDT & Coatings Inspection

Structural steel construction demands precision, performance, and reliability—especially in mission-critical infrastructure. At AEIS, we deliver a full spectrum of inspection and testing services that ensure conformance with design intent, applicable codes, and project specifications across all stages of steel construction.

Our work spans field and fabrication environments, supporting complex projects in transportation, energy, public infrastructure, high-rise construction, and beyond. With an expert team of inspectors, welding engineers, and NDT professionals, AEIS is a trusted partner for quality assurance and compliance.

Structural Inspection Verifications:

• The placement and size of the anchor bolts are correct
• Base plate grout is performed and samples of the grout tested in our laboratory to verify compressive strength (Grouting of Base Plates)
• Steel erection which would check for the proper steel piece (by ID number) is set in the correct location (Steel Erection)
• Bolting, including Skidmore Bolt Tension Calibrator and verification of calibrated wrench/ Rotation Capacity (Ro-Cap) tests etc.
• Welding Inspection – pre, during and post of Fillet, PJP, CJP, Flare Bevel, Arch Spot (Puddle) and other types of welds
• Metal deck and shear studs are installed as required
• Non-destructive testing of field Welds (magnetic particle, dye penetrant, ultrasonic, radiography or other tests) will be performed as mandated by the specifications

Pipe Inspection Verifications:

• Erection of piping spools as per PIDs and plan drawings
• Verification of appropriate piping fittings, hangers and other components
• Witnessing of Hydrostatic/ Pneumatic tests
• Nondestructive testing using RT, UT, PAUT, MT, PT, VT, ET and other techniques, as required
