Tender description

To carry out maintenance and repair work to Portgordon Harbour Lot 1: Portgordon Harbour is a tidal harbour consisting of two basins. Large areas of the harbour bed dry out at low tide. A finger pier, which is an extension of the East Quay, extends seawards beyond the harbour entrance and gives some protection to the entrance area from easterly storms. Two types of construction are evident in the walls and piers forming the harbour: -Mass concrete. -Stone masonry consisting of large blocks laid in course without mortar. The East Pier within the Harbour is of stone masonry. The stone masonry construction extends to a point a few metres outside the harbour entrance. Thereafter, the finger pier, which continues seawards, is of mass concrete construction. A concrete wave wall extends along part of the eastern edge of the East Pier. The wave wall is retaining beach shingle to full height. The West Pier, spurs and north part of the Mid Pier are predominantly of concrete construction. The southern part of the Mid Pier is constructed mainly of stone. The permanent works consist of: -Replacement of three sections of concrete wall to the West Pier and Outer Spur. The principal features of the works are as follows:- -Mobilisation and demobilisation to site -Establishment of access and reinstatement on completion of the Works -Establish procedures for the delivery of materials -Prepare and implement a Construction Phase Health and Safety Plan -Provide data for the Health and Safety File -Cutting out sections of concrete wave wall and replacing with new fibre concrete and steel dowels
