A.H. Beck was contracted to install 4 drilled shafts on an active railway on this railroad bridge in Sunderland, Vermont
This Railroad Bridge was completed in the countryside of Southwest Vermont over a pristine brook in Sunderland, Vermont. The Owner was the Vermont Agency of Transportation and the General Contractor was S&R Corporation out of Lowell, Massachusetts. This work was only 4-60” shafts to depths of 60’-70’ for a 65’ bridge but its construction posed some unique challenges. The location of each of the four shafts was directly on either side of an ACTIVE railway. Additionally, there was a public road right adjacent to the Railway. Careful planning and staging of equipment and materials was necessary in order not to impact traffic on the railroad or roadway. The drilled shafts were excavated using Bentonite slurry and then a full length permanent casing was installed per the design. During the placement of permanent casing, reinforcing cages and anchor bolts, everything needed to be below existing track level before trains could pass. Also AH Beck was able to adhere to strict environment controls successfully.
