Tejjy Inc.Delivers digitized 3D Laser Scanning and BIM Solutions for Big Walker Mountain Tunnel

WASHINGTON, DC, Va. - Feb. 13, 2025 - PRLog -- The Big Walker Mountain Tunnel is a key link in Virginia's transportation network, connecting critical routes that ensure smooth traffic flow through one of the state's most challenging topography. Given the tunnel's significant role, the renovation process needed to address its complex existing conditions. All while, integrating modern systems to improve structural integrity, and enhance operational efficiency.

The task was not without its challenges. Tejjy's team was required to capture intricate as-built data, accounting for complex elements such as long approach routes, and utilities. The team also had to account for Virginia's rugged terrain, ensuring the integration of topographical data to simulate the area's natural contours. Further complicating the project was the tunnel's proximity to the environmentally sensitive Appalachian Trail, which demanded strict adherence to environmental regulations throughout the renovation.

In response to these challenges, Tejjy deployed its advanced technological solutions, with LiDAR services, www.tejjy.com/our-services/bim-services/3d-laser-scanning-services at the forefront of the effort. Utilizing Leica's RTC 360, the company captured highly detailed, accurate as-built data, enabling the creation of precise as-built models that became the foundation of the renovation process. These models, in turn, streamlined design workflows, reducing errors and accelerating the project timeline.

Tejjy also integrated digitized BIM-GIS solutions to optimize the simulation of roadway connections. This was done to accommodate the tunnel's elevation changes and ensure the connectivity of the surrounding infrastructure. In addressing the environmental concerns of the Appalachian Trail, the expert 3D Laser scanning providers in Virginia used 7D BIM, enabling the team to incorporate eco-sensitive design principles. This digital integration ensured compliance with both environmental and safety regulations.

Collaboration was another key element of the project's success. Through BIM-MEPF coordination, Tejjy Inc. worked seamlessly with the project stakeholders to upgrade the portal building, generator facilities, and utility layouts. This resulted in a cohesive renovation plan that met both the technical challenges posed by the tunnel's location.

The Big Walker Mountain Tunnel project serves as a testament to Tejjy Inc.'s expertise in managing federal infrastructure projects. The digital workflow deployed by the company highlights its commitment to sustainability and regulatory compliance.

"By capitalizing on our digital solutions like 3D lidar scanning services and BIM workflows, we delivered a comprehensive renovation solution for the Big Walker Mountain Tunnel, ensuring efficiency along with environmental stewardship," said Sukh Singh, Sr. Vice-President, Tejjy Inc.
