The Prescott Park piers project is separated into two phases. The first phase will be for engineering design services and expedited permit application with the State of New Hampshire and City of Portsmouth. The second phase will be for marine construction services. It is the intent to award both phases to the same proposer. The work in this document addresses the need for replacement of failed structural pilings and bracing, as well as resetting existing rip rap to fortify the adjacent revetment. Failed pilings and bracing are located on the perimeter and interior of the piers, requiring the removal and replacement of topside decking to access interior pilings. The selected marine construction firm is to design, obtain permitting, and complete construction of these structural repairs. This work will include applying for and receiving permits as needed from the NH Department of Environmental Services. The selected firm will also complete and submit an application to the City of Portsmouth Conservation Commission for approval. 1.
