Wessex Water’s project to reconstruct Durleigh water treatment centre shows how the water industry is harnessing the use of digital technology to deliver projects faster, smarter and more safely. Wessex worked with AECOM to bring together a range of tools and technologies and form a comprehensive digital engineering approach to the scheme.
Common Data Environment: enabling collaboration across the supply chain and Wessex Water’s business (project management, engineering, procurement, operations), this has supported Wessex Water’s integrated delivery team approach.
Digital engineering and visualisation: the digital model fully integrates all civil, mechanical and electrical and process design. Ground penetrating radar, drone survey and laser scan data are used to ensure existing assets are accurately modelled. They create a seamless interface with the design of new plant. Automated clash detection has allowed more than 100 structural clashes to be eliminated during the design process, reducing the risk of change during construction. The model has been a powerful tool as part of value engineering; for example, the visualisation has helped rationalise layouts in the wastewater treatment and low lift pumping areas with a potential £300,000 saving.
Design for manufacture and assembly (DfMA): A DfMA approach has sought to maximise opportunities for off-site build, helping to de-risk the programme and ensure the scheme is delivered within the duration of the planned site outage. The federated model has been used to identify DfMA opportunities, providing equipment suppliers with an immediate understanding of the project. 3D supplier fabrication details are inputted into the design model to give confidence that the off-site manufactured components – stainless steel tanks, access platforms and process pipework – will integrate into the construction when delivered to site ready-made.
Simon Osborne from Wessex Water praised AECOM for “helping to shape our future approach to digital technology.”
