BAE Systems in Scotstoun

We have recently completed the reinstatement of the walls and cills at a dry dock at BAE Systems in Scotstoun, on behalf of our client Farrans Construction.  The replacement concrete works are to accommodate a new 300-tonne flap gate within an older dry dock, to aid BAE Systems vessel docking process.

Farrans provided an arch cofferdam to withstand the Clyde River, allowing the works to commence within the dry dock. We worked closely with their demolition sequence and temporary propping, to ensure the permanent works were constructed in sections to allow further demolition to be carried out.   The base slabs were up to 3m in depth and carried the large pivot connections for the bottom of the gate. From the base upwards, our team provided assistance in rebar design and produced a full temporary works solution to both dock walls, to within the design parameters of the project. This involved 5 lifts of a jump system, with the walls being formed by a single-sided system, resin anchored to the existing concrete and piles.



The walls were in total 18m high and had intricate exposed features and steps for guiding the gates and pulleys.  At the top of both walls, we further constructed equipment pits for the winches, latches and penstock. This involved complex bespoke formwork for the numerous angles, slopes and levels according to the equipment layout.

With the assistance of Farrans, works were completed on time and to a high standard. In total we placed 2,900m³ of concrete and 320 tonnes of rebar. We look forward to seeing the completed job once the new gate is operational.
