Traveling technology delivers faster roadway data

Vehicle-based geospatial technology boosts the speed and safety of gathering survey data for a variety of projects, such as building a transmission line. Instead of putting surveyors and engineers on the ground to collect information about local roads along a project’s construction routes, a vehicle equipped with data-collecting technology traverses the roadways on the construction path to capture information quickly. This method also improves safety by practically eliminating the need for personnel to stop along the roadway and leave the vehicle to collect information.

Hanson has recorded data with its geospatial imaging vehicle from over 85,000 miles of roadway for its clients and has an award-winning history of providing roadway services for our public- and private-sector clients, including energy companies. We use this experience to assist clients with construction traffic routing, permitting, roadway condition assessment and monitoring, damage claim resolution and roadway authority liaison services. Our clients have found that using Hanson in this capacity minimizes project delays caused by roadway and construction-route issues and improves community relations by providing a knowledgeable and independent contact for stakeholders’ questions and concerns.

All projects are assigned a licensed transportation engineer to oversee the project from start to finish, allowing owners to focus on constructing their projects on schedule. Hanson’s geospatial imaging vehicle is outfitted with a Trimble MX7 mobile imaging system to record the roadways along the construction routes. This system features Trimble’s VISION imaging technology, which makes it easy to quickly and completely capture road and site infrastructure information, including dimensions, positions and images with survey-grade accuracy. The system can take 360-degree, 30-megapixel, geo-referenced images at highway speeds and offers greater accuracy and speed than video recording. For projects that need data via LiDAR, Hanson utilizes Trimble’s MX2 laser scanner.

A typical project plan includes pre- and post-construction video monitoring of construction roadways with visual interim inspections performed by an experienced engineer during construction. Initial, interim and final reports summarizing road conditions are submitted to the client after the inspections are completed. To accomplish these objectives and fulfill the requirements of our projects, Hanson offers a professional and experienced staff that works closely with clients and local agencies. Hanson’s road monitoring team has managed over 60 transmission line construction road monitoring projects, including over 2,000 miles of roadway.
