Pre-Mod Mappings

  • Verifies that existing field conditions match the assumptions built into proposed modification engineering drawings

  • Identifies member, connection, or equipment discrepancies before crews are mobilized to the site

  • Prevents costly change orders, project delays, and safety hazards caused by unexpected field conditions

  • Protects carriers, tower owners, and construction crews by eliminating surprises before work begins

Before any modification work begins, a pre-mod mapping ensures that the existing structure matches the assumptions built into the engineering drawings. Our inspectors verify member sizes, connection details, and current equipment configurations against the proposed modification plans, flagging any discrepancies before crews are ever deployed. Catching these issues early prevents costly change orders, delays, and safety hazards on the job.

Pre-mod mappings are a best practice that protects everyone involved — the carrier, the tower owner, and the crew doing the work. By confirming field conditions ahead of time, we help ensure that modification projects go smoothly from day one, with no surprises waiting at the top.
