Professional Excavator Information & Resources – Iowa One Call


Excavators are responsible for notifying Iowa One Call of their proposed excavations so facility operators with underground facilities near the excavation site can be informed of pending excavation. Excavators are required by law to notify Iowa One Call 48 hours in advance (excluding weekends and holidays) before beginning excavation.

ITIC – Online Ticketing System for Professional Excavators

White Lining

Excavators are required by law to identify the area of proposed excavation using white paint, stakes, or other suitable white markings in a manner that will enable utility operators to know the boundaries of the proposed excavation activities.

When Should I Call?

Contact Iowa One Call any time you plan to excavate. Whether it’s a small or a large construction project, you must submit a locate request at least 48 hours (excluding Saturdays, Sundays and legal holidays) prior to excavation. Iowa One Call will notify the owners/operators of underground facilities who participate in Iowa One Call. The various underground facility operators will dispatch “locate” personnel to the area to mark the underground facility locations with flags and paint markings, showing where underground facilities are located so the excavator can avoid damaging the facilities. Iowa law applies to professional contractors as well as homeowners, and encompasses a wide array of outdoor projects including:

  • Installing a fence
  • Planting trees or shrubs
  • Building a patio, addition, deck, garage, outdoor shed or any similar structure that requires any form of digging
  • Putting in a new driveway
  • Installing a septic system or water drainage system
  • Terracing or landscaping

ITIC, the electronic ticket entry system, is a user-friendly internet-based application available for use by anyone planning an excavation. For more information, and to register for a username and password to use ITIC, please click the “Submit a Ticket” button above.

Things To Remember

A ticket is valid for 20 calendar days from the time of the call.

ALWAYS check your ticket status before beginning excavation using Iowa One Call’s Positive Response System.
