Project details
North Shields Fish Quay is located on the North East Coast of England and is the region’s main fishing port. At approximately 100m in length, the Protection Jetty was originally constructed in 1895. Due to deterioration of this timber piled structure, Southbay were awarded a design and build contract to refurbishment the jetty in the form of the installation of new bearing piles, and the construction of a new Reinforced Concrete (RC) deck.
Initial works involved disconnecting existing services, and the removal of a canopy structure. Due to the reduced load capacity of the existing structure, temporary works in the form of steel grillage was used as a platform for an 80T Crawler Crane. Working across the jetty structure, holes were then cored into the RC deck, allowing bearing piles measuring 473mm by 11.1mm by 23m in length to be pitched into position. Using temporary guides fixed to the deck, the piles were then driven to refusal using a Vibro Hammer and impact hammer. Further piling works included the installation of UC Fender Piles, which were pitched using a piling frame positioned over the side of the quay. As the piling works advanced across the structure, a new RC deck system was installed. This consisted of the installation of pre-cast concrete coping along the edge of the quay, which allowed for the installation of reinforcement. Multiple in-situ concrete pours were then cast to form the new deck slab. A series of 10T Mooring Bollards have been fixed to the new deck system at 5m centres along the length of the quay.
Further works included the replacement of fendering, services, installation of ladders and the reinstatement of the steel canopy structure. In addition, a new Cathodic Protection system has been installed. In order to protect vessels from the tidal flow passing underneath the jetty, a new Wave Screen consisting of precast concrete panels, has been installed to the gut side of the structure. The panels were installed between the fender piles.
The project was delivered within a limited site footprint, with the jetty subject to daily vessel movements associated with the fish market. In addition, significant consideration was required when transporting materials to the site, with a number of public facilities located across the site boundary. The project was delivered with no reportable incidents.
