What makes it interesting?
Construction occurred in a fully-operating railroad tunnel, and roadway traffic was not to be restricted by erection equipment.
How HCSS Software assisted with this project
The flexibility of HeavyBid was important here as every item was non-typical. HeavyBid handles just about any pricing strategies with ease.
In the CSX J&L Tunnel Improvements project, Mascaro had to carefully design-build the removal of an existing rail tunnel roof under live train traffic, raise the walls to meet specified clearances, and replace the roof with precast panels. Mascaro engineered the demolition and replacement around the use of a crane set on top of the old and new roof, with trains running below. This project increased the vertical clearance inside a 1600-linear-foot section of a CSX railroad tunnel and included utility relocation, drainage improvements, and removal of overhead structures near both tunnel portals. Mascaro self-performed grading, drainage, temporary shoring, demolition, water and sewer relocation, and tunnel wall and roof construction, including all concrete, rebar, and steel installation.
