Client: Generation Ltd Duncan Street is a residential development in Salford, designed to contribute to the area's growing urban renewal. The 11-storey building houses 83 modern apartments, featuring a stepped-back design to maximise external space and offer stunning views of the city. In addition to the residential units, the development includes ground-floor parking and a dedicated cycle hub, supporting a sustainable lifestyle for its residents. Duncan Street's location within Salford's regeneration zone, coupled with its proximity to local amenities and public transport, makes it an ideal place to live for city commuters and families alike. Services we provided Civil & Infrastructure Engineering Geotechnical & Ground Engineering Ground Investigation & Land Quality Structural Engineering Water Engineering & Flood Risk Our Role BWB was appointed to provide structural engineering services for the Duncan Street project, which included developing designs for the building’s foundations, structure, and external envelope. Our team faced significant constraints due to the site’s proximity to Network Rail infrastructure, necessitating innovative solutions to prevent construction from disrupting rail operations. Innovative approach Our approach involved designing structural modules that could be assembled off-site and then delivered to the site for installation. Our design utilised upper-floor walls as deep beams formed from pre-cast concrete, which minimised the transfer depth and retained the full scale of the development. Robust foundation Our team also oversaw the design of the foundation and drainage systems, ensuring the building was supported by a robust foundation. The drainage system design also effectively managed surface water, reducing flood risks and supporting long-term sustainability. Tight constraints The tight constraints are posed by the site’s location next to a 6-meter retaining wall and Network Rail infrastructure. This required a tailored design approach. Our modular construction strategy provided the necessary flexibility while minimising impact on the surrounding area.
