"Joseph, and the Ayres team, are very good to work with.  They stuck to the forecasted delivery dates, and if there was an unforeseen issue to meet that date, Joseph was on the phone or email right away letting me know how this would impact the delivery of documents.  Ayres did thorough research into the information we were needing which resulted in easy application to our drawings.  We will be contacting Ayres for any future SUE needs."

Quality Data You Can Depend On

Our crews prioritize thorough fieldwork and documentation to deliver accurate, defensible utility data, not rushed assumptions. Technicians are trained on multiple locating technologies and methods, with findings compared against available utility records (QLD). Each project undergoes a multi-step review process, from field verification to office QA/QC and final oversight by a licensed professional engineer. This approach results in consistent, reliable utility data so you can design and build with confidence.

Comprehensive SUE Services

Ayres provides a full range of services from records research and quality level development through field investigation and survey, delivered by one integrated team. Our SUE services include QLD utility records research, QLB designating, QLA air-vacuum excavation, and survey. Everything you need, all in one place.

Regional Experience Across Colorado

Ayres’ SUE team is based in Fort Collins, with teams mobilizing statewide as project needs emerge. We bring extensive experience delivering SUE services throughout Colorado, including projects across the Front Range and Western Slope. Our teams support multiple on-call contracts statewide and are equipped to mobilize wherever projects require, from urban corridors to rural county roads and remote mountain locations.

One Contact, One Responsive Team

A dedicated project manager oversees all aspects of the SUE work, serving as a single point of contact from kickoff through delivery. This integrated approach streamlines coordination, ensures timely communication, and keeps you informed with clear, consistent updates. Our commitment to consistent communication helps prevent delays and helps keep your team aligned.
