Complete Structure Demolition, Selective Demolition
ACECO’s scope included large-scale demolition of the VA Tunnel owned by CSX Transportation, Inc. This incorporated a section of the rail line covering approximately 7,000 linear feet divided into fifteen sections, each having different requirements. Several sections required the existing North wall of the tunnel to remain intact to prepare for new construction, while others included the entire tunnel (walls, roof, and track foundations) to be demolished. This necessitated a complex system of shoring and bracing to protect existing structure and ensure safety during the demolition, and a carefully-designed demolition plan to be followed meticulously throughout the 17-month project.
