Erector Tripping Points – Part 1: Codes and Criteria

We’ve begun to see a trend with some of our Erector clients. One of these is with inspection.

Most erectors are still under the impression that “inspection is by the Owner” and they struggle with how to provide a qualified Quality Control Inspector to meet the requirement. There are several ways this can be accomplished.

Hire or train a CWI

While this may not be the quickest or most cost-effective way to fulfill the requirement, you should consider this an investment in your people. Hiring or training a CWI ensures that the person doing the inspection knows what they are doing and will produce a quality result each time.

Clearly define the inspection role for existing staff

If you are assigning the role of inspection to a General Superintendent or working Foreman, be sure the role is clearly defined. This person must have the ability to switch hats to keep good work flow. Laying out expectations ahead of time will make life easier.

Read up on AWS D1.1 – Section

This section of D1.1 allows a qualified inspector to be based on experience, knowledge, and training. There is a similar clause in AISC Chapter N.

This brings us to another stumbling point. Most erectors are not familiar with the inspection requirements of AISC Chapter N. Chapter N lays out two important requirements:

  • What to inspect – quality records, welding, bolting, dimensional, details, metal deck
  • When to inspect – prior to work beginning, during the work, after the work

Lastly, we recommend that erectors brush up on their knowledge of these industry codes, which will help you fulfill the inspection requirements.


We hope these tips are helpful in getting you on the right path for inspection success. In Part 2, we’ll discuss methods to document final inspections, as well as use of inspection tools.
