This contract, the 3rd and final phase of the overall Dunoon Flood Prevention Scheme, was to provide an overflow channel in the lower reaches of the Milton Burn which over the years, had been prone to overtopping resulting in severe flooding to the surrounding town centre area.
The major element of the works comprised the construction of approximately 110m of new 3m high reinforced concrete walls and base channel within the lower reaches of the burn, in a constrained location between residential properties and the town’s main supermarket. With a large catchment area from the hillside behind the town and with rapid entry time into the drainage system, the burn was prone to flash flooding with fast-flowing high level flows resulting at short notice. A piled, temporary works solution was installed to contain the flows and enable construction works to progress.
The flows are controlled by the construction of new weir structure within the Milton
Burn together with an inlet chamber and connection to a 1400mm overflow pipeline installed under a previous phase of the scheme.
The project also included the replacement of the existing footbridge over Milton Burn at St Mun`s School with the associated reconfiguration of new footpaths, reconstruction and reinstatement of part of the adjacent supermarket car-park and the removal of extensive invasive Japanese knotweed in the burn area
The overall project involves the off-site fabrication and installation of a new linkspan structure at Oban Ferry Terminal for client Caledonian Maritime Assets Ltd (CMal).
