Building a Surveying and Mapping Firm with 3D Technology

NCDOT – Green River Gorge Bridge Project with RIEGL VZ-400i (shown) and RIEGL miniVUX-3UAV

LiDAR News recently published an article featuring an interview with Joey Wilson, Founder of Wilson & Associates, and their use of RIEGL 3D Laser Scanning/LiDAR technology in their various projects. As a leader in the surveying & engineering industry over the past 40 years, Wilson & Associates is the largest construction surveying company in the state of Tennessee.

In 2018 and 2019, they purchased a RIEGL VZ-400i Terrestrial Laser Scanner and a RIEGL miniVUX-3UAV Unmanned Sensor for a UAS system. “We bought RIEGL scanners due to their ease of use, their capability to auto register point clouds, and their accuracy.” said Joey Wilson. “They have a reputation in the industry for being some of the most accurate scanners on the market.  They have proven their worth to the firm many times over.

In the article link below, learn how RIEGL technology was used in a survey of the Green River Gorge Bridge Project, where the twin bridges were scanned to mitigate any steel expansion caused by direct sunlight; or to perform a vessel replacement alignment survey for the Primester Chemical Plant in Kingsport, TN.

About Wilson & Associates

Wilson & Associates has been at the front line of the Surveying and Engineering industry for more than 40 years, and now is the largest construction surveying company in the state of Tennessee.

While Civil Engineering, Land Planning, and Environmental Services are an integral part of the company, Construction Surveying remains the foundation. The company has provided engineering and surveying services on more than $4 billion in highway, commercial, and industrial construction and design projects.
Started by Joe Charles Wilson in 1972 and now in the hands of his sons, Joey and Justin, WA is using advanced and innovative techniques, such as laser scanning for complex rehabilitation projects and civil site surveys, as well as a constructability review process to identify potential conflicts before a construction issue arises.

WA encompasses a wide variety of tools used to complete a project on time and under budget, while setting itself apart from its competitors with the ability to supply the client with highly detailed and accurate models that leave nothing to guesswork for the contractor.
