Structural steel bridge fabrication is built to AASHTO and AISC standards with strict certification, and a steel fabricator that does not read the bridge requirements is pricing the wrong work.
What bridge steel sets
Bridge steel fabrication follows the AASHTO bridge specifications and AISC, with welding to AWS bridge code, fracture critical requirements, and an AISC bridge certification often required. The DOT package sets the fabrication scope, the certification, the welding, and the inspection the fabricator must provide.
Why bridge steel scope is easy to misprice
The fracture critical requirements, the bridge certification, the welding, and the inspection sit in the DOT special provisions and the plans, not the title, and they exceed building steel requirements. A fabricator that prices it as building steel underprices the certification and quality control.
How an AI bid agent reads bridge steel
An AI bid agent reads each DOT steel package, identifies the AASHTO and AISC bridge requirements, and surfaces the certification, the welding, and the inspection that drive the work. The fabricator prices the actual scope.
You can see how the agent reads a bridge steel package in our AI bid agent demo for specialty trade contractors. It pulls the AASHTO and AISC bridge fabrication, certification, and inspection scope so the work is priced.
