95 MECHANIC STREET WHARF AND SEAWALL REPLACEMENT

April 8, 2021

The City has completed contract documents and intends to go out to bid this week on the 95 Mechanic Street Seawall and Wharf Replacement project. The project is part of the City’s ongoing responsibility to maintain seawalls.

Background

Following the collapse on August 4th of the 95 Mechanic Street Wharf, Portsmouth DPW brought in an emergency team to complete demolition of the buildings and to secure the site. A Pickering Marine barge and crane worked from the water while Renaud Industries deployed two excavators to take apart the buildings. The demolition work does not include the existing house.

The City acquired the property in 2014 in anticipation of the need to replace the Mechanic Street pump station. That work is included in the FY23 & FY24 CIP. At the time of purchase, City engineers determined that the wharf and its c. 1949 buildings were beyond repair and not safe to enter. The buildings were cleaned out and a perimeter fence was installed.

Before the collapse, City staff had been developing documents to request a construction bid to replace the wharf and seawall as first steps that needed to be completed before other future site improvements at 95 Mechanic Street and the public properties on either side. Staff had also secured the appropriate DES permits in anticipation of the demolition work. Because of the emergency demolition in August, the City will be requesting bids to include just the construction of the new wharf and deck and work on the sea wall.

The City held a public meeting on October 3 to update the neighborhood and other interested residents on the plans for rebuilding the seawall and reconstructing the wharf. The plan must be implemented in phases, because to keep the pumping station in operation, the new station must be built in an adjacent location. The meeting is intended to discuss opportunities presented by the reconfiguration of the site that might be included in the master plan for the property.
