Welding Service Bid — $28K Field Package

A South Texas fabrication shop used IronKit to bid on a field welding package for a gas processing facility turnaround. The scope covered 6t and 8t pipe supports, structural platform modifications, and miscellaneous attachments — all requiring code-qualified welders on a short schedule. IronKit generated a clean itemized bid that separated setup and mobilization, field weld hours, and consumables. The job was awarded at $28,400.

Frequently Asked Questions

What codes apply to process plant field welding?

ASME Section IX for procedure and welder qualification, AWS D1.1 for structural welds, API 1104 for piping. The owner typically provides the CWI inspection. IronKit generates bids with code references and WPS availability notes included.

How do you price field welding vs. shop welding?

Field rates are 15–25% higher than shop rates to cover mobilization, per diem, and reduced productivity in non-controlled environments. IronKit separates these costs so the client sees exactly what they are paying for setup vs. actual weld time.

What if the scope changes during the turnaround?

Any scope change requires a written change order before work is performed. IronKit has a change order generator for exactly this scenario — it ties the new scope to the same rate basis used in the original bid.
