Massachusetts Port Authority
Conley Container Terminal - Boston, MA
The project involves construction of a 1300 LF long x 110 LF wide deep foundation supported reinforced concrete pier for berthing of cargo container vessels at Conley Terminal in South Boston. The deep foundation consists of 862 26” and 30” diameter steel pipe piles that are between 60 and 105 feet in length. Approximately 100 of the 30” diameter piles along the face of the pier have drilled rock sockets in locations with minimal overburden. The inshore and outshore crane beams and pile caps are cast in place pieces and lock together to provide the framework for the deck. The deck consists of 870 precast deck panels with a cast in place topping slab. The pier work also includes new gantry crane running rail, marine bollards, fenders, drainage, water and electrical installed on the deck. Once completed, the deck adds an additional 158,000 square feet of additional pier space for Massport to berth large cargo container vessels. In addition to the pier work, there is approximately 25,000 SY of site work performed on the project. The site work entails installation of new water mains, storm drainage systems, duct banks, high mast lighting and new asphalt which is all designed to an extra heavy duty load rating. The landside portion of the project adds approximately 150 spaces to stack cargo containers. Overall, this project will allow Massport to substantially increase import and export of cargo through Conley Terminal.
