In 2007, a £20m Mechanical and Biological Treatment (MBT) facility in Westbury was commissioned by Hills Group. This facility allowed for an increase in the proportion of Wiltshire’s municipal waste diverted from landfill to more than 80%, with the process handling 60,000 tonnes of waste per year. The treatment process requires a building infrastructure that includes for extensive reinforced concrete reception pits, a large treatment hall, processing and storage areas and office and welfare facilities.
With high velocity cranes operating over the reception and treatment areas, we were challenged to overcome a variety of foundation problems to support these high intensity loads. We were involved in the original concept of the scheme and provided structural input during the early development stages. When the project was given the go-ahead, the superstructure and substructure designs were to be carried out simultaneously and we were tasked with designing the foundations using loads supplied by others. Over 250 tonnes of reinforcement were designed and detailed in less than three months to meet the contract programme, submitted by Principal Contractor Interserve.
