Utilizing the latest in laser scanning technology, Precise Visual Technologies was able to quickly and comprehensively capture accurate as-built data on the existing space.
“Accuracy was critical,” said James Kovalik, PLS, technology development manager for Precise Visual Technologies. “Laser scanning with the Leica ScanStation was the only way to accomplish the task.”
Of course, retrofitting a large processing facility can be done without laser scanning. The traditional approach relies on using lifts and ladders to obtain hand measurements and makes assumptions based on perfect real-world conditions. The process is laborious, risky and prone to error, leaving much to be desired. Obtaining the necessary field surveys and documentation typically requires multiple costly site visits over a period of weeks, and measurements must be double and triple checked to ensure accuracy.
In contrast, our team spent just 10 hours onsite with the latest Leica ScanStation equipment and quickly collected comprehensive and accurate as-built documentation of all necessary piping, tanks, valves, structural and electrical components, and site features associated with the project area.
The accuracy of the scans allowed the engineering team to thoroughly explore the proposed design with the client’s engineering, safety, and operations teams to jointly understand how all facets of construction would impact existing operations prior to actual construction taking place.
“With 3D laser scanning, the project team was able to thoroughly review construction issues and conflicts prior to construction, which simplified that phase and minimized the risks of unexpected changes and downtime,” Kovalik said. “Having the accurate 3D data also streamlined construction by reducing RFIs [requests for information] from the contractor.”
Transporting this massive tank from Texas to West Virginia was a complicated endeavor that required careful coordination among multiple agencies and organizations along the way. One thing the project’s stakeholders did not need to worry about, though, was the installation of the tank once it arrived safely at the facility. Thanks to the innovative approach utilizing 3D laser scanning, the installation onsite was flawless.
“The project was completed within the planned schedule and budget, and, most importantly, without interrupting the existing production or processing capabilities,” Kovalik said. “Through careful planning and design of the proposed facility, as well as extensive collaboration with their engineering team by using the Leica ScanStation, we were able to meet the client’s needs and achieve a successful installation.”
