Precision Utility Locating For Safer Excavation
Windsor Underground uses advanced utility locating techniques to identify and mark underground lines with precision before any construction, trenching, or boring begins. Our team utilizes electromagnetic detection and visual confirmation methods to accurately trace subsurface utilities. Whether you’re planning excavation, horizontal directional drilling, or installing new dry utility infrastructure, we map all critical systems—including gas, electric, water, sewer, telecom, and fiber—to prevent service disruptions and avoid costly or dangerous mistakes. Each locate is documented, clearly marked in the field, and communicated to stakeholders to ensure safe and informed construction planning.
Accurate utility locating is essential for compliance with Arizona 811 regulations and for ensuring trenching and boring operations proceed without risk. Our services are a key component of pre-construction planning and active job site operations, helping reduce the risk of utility strikes, work stoppages, and fines. We support general contractors, developers, and municipalities by providing reliable subsurface data that aligns with project plans, utility records, and field conditions. By proactively identifying utility conflicts and aligning markings with construction schedules, we keep jobsites running efficiently and help ensure public safety, code compliance, and utility service continuity.
Preventing Damage Before It Happens
Accidental utility hits are among the most expensive and dangerous setbacks on a jobsite. We minimize that risk by deploying electronic detection tools and verifying utility locations before excavation begins. Our trained technicians follow industry best practices and local standards to ensure accurate, documented markings that guide your next phase.
Real Results From Smart Locating
Our locating services have helped countless projects proceed safely, on time, and without conflict. Whether scanning a commercial complex, subdivision, or road corridor, we bring a proactive safety-first approach. Our accurate utility mapping reduces the risk of utility strikes and unexpected delays, allowing contractors to dig with confidence. This reliability has made us a trusted partner for developers, municipalities, and utility providers across Arizona.
Prior to trenching on a 100-lot residential development, Windsor Underground conducted comprehensive utility locating to verify the presence of existing subsurface infrastructure. Our technicians identified key telecom and power lines, verifying trench zones were clear for safe excavation. Color-coded markings were applied across the site to guide trench crews and reduce the risk of accidental strikes. This proactive approach ensured all utility conflicts were mitigated before excavation began.

Before renovation work on a high-traffic commercial property, we performed a detailed utility locating scan to detect underground conflicts. Our team identified both gas and electric conduit paths and coordinated directly with SRP and Southwest Gas to validate findings. A CAD-based utility overlay was generated and delivered to the client, allowing the construction team to adjust plans accordingly. The result was a safer, more predictable excavation environment.

Windsor Underground provided utility locating services for a large-scale municipal road expansion, supporting pre-boring and paving work. We performed a long linear scan across multiple utility zones, identifying critical infrastructure such as buried fiber optics and high-voltage lines. Our findings were used to protect these utilities during construction, and we delivered full damage prevention documentation to city officials. This service helped minimize liability and ensured public safety during the project.

Our Utility Locating Process
We approach every utility locating project with methodical care and clear communication. Our goal is to provide actionable, accurate data to ensure all future excavation is safe and compliant. We begin with a detailed review of existing utility records and coordinate closely with Arizona 811 and private utility stakeholders. This process helps eliminate unknowns, reduce excavation risk, and ensure full project readiness before breaking ground.
Accurate locating today means fewer delays and zero utility hits tomorrow.
