Baker Mallett were appointed by English Heritage to provide full pre and post contract Quantity Surveying services on the stabilisation of the Boundary Wall along with drainage works to the South Platform and Gun Terrace at Upnor Castle.
The project involved undertaking structural works to the East Boundary Wall and drainage works to the South Platform and Gun Terrace.
Upnor Castle is a 16th Century Elizabethan Artillery Fort located on the bank of the River Medway in Kent, opposite, and downriver, from Chatham Dockyard. The fort was constructed on the orders of Elizabeth I to protect both the dockyard and ships of the Royal Navy anchored in the Medway. The castle consists of a two storeyed main building protected by a curtain wall and towers, with a gun platform projecting into the river.
Works were required to stabilise the East Boundary Wall, involving installation of a proprietary piling system which then facilitated the removal of steel cable ties installed at an earlier date to restrain the wall and arrest the lean.
New brick piers were also constructed which were carefully, and sympathetically, blended into the existing brickwork to preserve the character of this significant scheduled ancient monument.
Replacement drainage works were also undertaken to the South Platform and gun terrace which involved UO, and subsequently reinstating, the historic paving.
