Comprehensive System Features

Visual 811 Ordering & Tracking

Complete locate management system for utility locate requests, visually showing status of construction workzones. Color coded to allow staff to quickly determine status:

Active
Active but time to renew
Active and new locates have been requested
Expired

Field Capture & Document

Turn field observations into documentation. Capture geolocated photos of utility markings and SUE investigations, digitize findings directly using drone imagery, and maintain timestamped records of all locate activities. Every photo, measurement, and observation becomes part of a traceable audit trail that satisfies regulatory requirements and protects against disputes.

Pothole Management

Plan test hole locations on a map displaying design of new infrastructure; document findings with where and when including geotagged photos and measurements; Allow field staff to visualize location and historical information from past investigation on a interactive map.

Utility Console

Allows the utility management team to track and maintain planned, newly installed, existing, and abandoned utilities throughout construction. All on a visual interface linked to authoritative records.

GDP requests and active permit management are seamlessly integrated into the utility console, providing real-time visibility and control.

Ground Disturbance Permitting

A streamlined workflow to issue Ground Disturbance Permits (GDPs). Field personnel draw the area requiring ground disturbance directly on the map and submit it. The utility team reviews the request, identifies required test holes and other conditions, and then issues the permit. The software automatically generates a cover page showing a high-resolution image of the work area, locations of existing utilities, the permit number, expiry date, and key permit requirements. The PDF permit package can include 811 locate information, limits of approach, utility owner contact details, and any other pre-selected information.

Quality Level Management

Enforce QL-A through QL-D classifications with proper validation, ensuring compliance with ASCE 38-22 professional standards.

Localized Utility Map via QR Code

Scan the QR code and see the high-resolution utility map centered on their exact location. Utilities are overlayed on current drone imagery showing both legacy infrastructure and new installations. Zero setup, zero apps, simple utility visibility.

Drone-Verified Utility Alignment Capture

Once the utility rep marks the utility route with chevrons, an RTK-enabled drone is flown to capture high-resolution imagery and generate a georeferenced orthomosaic. A draftsperson or CAD technician then digitizes the utility alignment from the chevrons. This new linework is overlaid on existing GIS data to quickly flag any discrepancies. The updated linework is uploaded to the project portal, creating a time-stamped, shareable audit trail showing exactly where every marker was placed.

Authoritative Data

Single source of truth for utilities inside construction area.

The system maintains network topology, connectivity/associations, rules, branch versioning, QA (dirty areas/errors), and trace/diagram capabilities. That is how you keep the "single source of truth" consistent while multiple teams edit and as-built the corridor.

Data Quality Assurance

FHWA's SUE guidance
FHWA SUE Guidance
Federal Highway Administration guidance on Subsurface Utility Engineering - emphasizes the importance of proper quality level classification and professional SUE investigation methods.

explicitly warns that record-based (QL-D) and surface-feature (QL-C) information is often incomplete or erroneous and not design-grade; only QL-B/A investigations raise confidence appropriately.

Professional SUE Standards

ASCE 38-22
ASCE 38-22
Standard Guideline for Investigating and Documenting Existing Utilities - defines quality levels (QL-A through QL-D) and professional SUE standards.
Learn More →
defines how you obtain utility locations (records correlation, surface geophysics for QL-B, daylighted measurements for QL-A) and how you qualify their reliability.

A map that displays orthophotos or imported CAD doesn't perform geophysics or test holes, can't promote QL-D/C data to QL-B/A, and doesn't meet the professional sign-off expectations of the standard.

Even 811/One-Call paint marks are not automatically QL-B without proper detection and documentation.
