Gedeon GRC Consulting served as the lead civil and traffic engineer for the design-build of the rehabilitation of the Roseville Tunnel and associated track bed work in Byram Township, N.J. The design was performed on a fast-track schedule, requiring multiple submissions and involved extensive coordination with all parties. Due to the quick nature of this project, special consideration was given to document controls using Bluebeam, Autodesk BIM 360 and Autodesk Construction Cloud to track/maintain deliverable schedules.

The Roseville Tunnel was constructed in the early 1900s and is approximately 1,000 ft long with approximately 85% unlined exposed rocks and remainder of concrete liner. Since the project is surrounded by wetlands, the design involved a detailed erosion and sedimentation control plan along with check dams and silt fences to prevent silting during construction.

At no cost to the client, Gedeon GRC is utilizing the Flyability Elios 3, a LiDAR-equipped drone, to map the inside of the tunnel. Periodic scans of the site can be completed in under 30 minutes and converted into CAD models, enabling the contractor to confirm the site is being built according to the design specifications.

Gedeon GRC is a multidisciplinary firm with extensive experience in traffic/civil/structural engineering and CM/Cl. Our extensive portfolio of design-build and tunnel inspection projects, along with a strong working relationship with the lead designer, Delve Underground, have uniquely positioned us as a convenient one-stop shop for this project.
