GEI worked with MASSPORT Capital Programs to develop a comprehensive long term solution for rehabilitation of Berths 11 & 12 at the Conley Container Terminal to allow berthing of the New Panamax class vessels.

GEI was retained by MASSPORT to lead the rehabilitation of Conley Terminal’s only active container berths in South Boston, MA. Maintaining container operations was critical in development of repairs and phasing of work. The $30 million rehabilitation is key to meeting MASSPORT’s goal to provide berthing for the current 9,000 TEU container vessels as well as future New Panamax vessels that will be calling at Boston’s only container facility. The key elements of the rehabilitation project included:

• Installation at the face of the berth, of a toe stabilization wall to allow dredging and deepening of Berth 11 to 50-foot draft for accommodation of New Panamax vessels.
• Complete fender and bollard replacement at Berths 11 and 12 to accommodate larger vessels
• Installation of a new inshore bulkhead to eliminate backland fill loss and regain facility load capacity.
• Replacement of 300 timber piles.
• Construction of six lateral load resistant platforms through-out the pier to resist earthquake, STS crane, vessel berthing and mooring, toe wall, inshore bulkhead and other lateral loads on Berth 11.
  Concrete surface repairs on piles and deck areas
• Replacement of expansion joints and crane rails.
  • Dredging to 50 foot depth including rock removal.

GEI has completed multiple investigations including above and underwater structural assessments, geotechnical investigation, topographic and hydrographic surveys, berthing and mooring load investigation and review of existing pier foundation capacity for lateral loading. GEI completed final design including development of complete construction documents for rehabilitation of Berth 11. Fender replacement construction documents were also completed for Berth 12. GEI provided construction phase services and the project was recently completed.
