McLaughlin & Harvey have received a CEEQUAL award rating of Excellent for the Torry Quay redevelopment.
During the project, the team were faced with different challenges, including diminishing risk to the water environment and marine ecology, material use and water minimisation, and local community and stakeholder liaison.
The project involved the construction of a new Quay within the River Dee Dock, including infilling the dock, dredging, concrete paving, and all associated Quay furniture and service works.
Before construction began, the Scottish Natural Heritage advised that the development was located in an area designated as a Special Area of Conservation (SAC) under the EC Habitats Directive for important populations of Freshwater Pearl Mussel, Otter and Atlantic Salmon. The Aberdeen Harbour area is also identified as an important feeding area and transit route for the Moray Firth (SAC) Bottlenose Dolphin population.
Working closely with the Client’s Ecological Clerk of Works and regulatory / advisory body representatives in the area, the team managed to effectively diminish the risk to the natural water environment during the construction process. A mitigation strategy was adopted to protect the local ecology through the use of an extensive silt curtain during the infilling operation. During the dredging works a Marine Mammal Observer was employed to ensure the area was clear of cetaceans and pinnipeds. Soft start methods ensured that any undetected animals were able to leave the vicinity of the works and therefore minimise the risk of harm.
The significant resources required for infilling of the quay area prompted the identification of local opportunities for reuse and the procurement of locally quarried materials. This approach resulted in 78% of the total on-site demolition waste being reused as fill, and over 12,000m3 of spoil material from previous phases being incorporated into the reclamation zone; minimising the extraction of virgin materials and making significant cost and carbon savings.
McLaughlin & Harvey worked in conjunction with Aberdeen Harbour Board to ensure that stakeholders were provided the opportunity to engage and influence the project. As part of the Considerate Constructor’s Scheme (CCS), the project team employed clearly defined channels of communication for feedback from the community and stakeholders to help the team to implement nuisance reduction measures where necessary. The project team also engaged with local nurseries, schools and colleges, providing various donations to help stimulate the relevant level of learning, ranging from construction toys to site tours.
