GENERAL OVERVIEW

Dry Dock 4 is located at the Norfolk Naval Shipyard in Portsmouth, Virginia. The dry dock, constructed in 1919, supports repairing, overhauling, and modernizing ships and submarines.

The dry dock is approximately 1,012’ long, 144’ wide at coping level, and 51’ deep. The existing walls and floors are primarily unreinforced concrete. The existing caisson seat is granite blocks, and the caisson is of the older hydrometer style. Due to its age, Dry Dock 4 is in need of renovations to meet Navy certification requirements.

The RM12-1896 project includes, but is not limited to:

Demolition of existing caisson and caisson seat.

Construction of a temporary cofferdam.

Construction of new flood-through caisson and caisson seat. (Figure 2)

Pinning the dry dock floor with the installation of micropiles. (Figure 5)

Removal of up to 36” of concrete from the floor and 24” of concrete from the wall of the dry dock. (Figure 5) o Concrete removal program shall include provisions to repair leaking cracks.

Installation of precast concrete panels along dry dock walls. The top section of the wall will include an integral utility trench and extended coping wall to provide flood protection.

o Main dewatering pumps

Three pumps with a proposed flow rate of 85,000 gpm per pump o Drainage pumps

Three pumps with a proposed flow rate of 5,000 gpm per pump o Sump Pumps

Two pumps with a proposed flow rate of 300 gpm per pump o HVAC o Lighting o Controls o Electrical infrastructure

Reconstruction of pumpwell roof system to meet a design flood elevation of 106. (Figure
