Client: Miller Birch Developments Trinity House, E-On’s new headquarters in Nottingham, is a modern eight-storey office building located within the city’s regenerated business quarter. The 105,000 sq ft development offers Grade A office space, with high levels of natural light provided by full-height glazing and a central atrium. Designed to accommodate a flexible working environment, the building features both open-plan and cellular offices, alongside formal and informal meeting rooms to support diverse working practices. Situated next to the Grade II-listed Guildhall, Trinity House incorporates sustainable design principles, earning it a BREEAM Excellent rating. Services we provided Structural Engineering Civil & Infrastructure Engineering Digital Engineering & BIM Geotechnical & Ground Engineering Ground Investigation & Land Quality Transport Planning & Traffic Engineering Our Role BWB was appointed as the lead engineering consultant for Trinity House, delivering a wide range of integrated engineering services that enabled the project’s success. Our initial involvement included conducting extensive geo-environmental investigations and developing a detailed remediation strategy to address site contamination risks. Structural design Given the building’s location on a constrained site within the city centre, our civil engineering team worked closely with the design team to overcome the complexities of foundation and basement design, ensuring the building’s stability while minimising disruption to the surrounding area. Our structural design services encompassed the use of Building Information Modelling (BIM) technology, allowing us to optimise the design and enhance coordination with other stakeholders. Infrastructure and site engineering Given the building’s location on a constrained site within the city centre, our civil engineering team worked closely with the design team to overcome the complexities of foundation and basement design, ensuring the building’s stability while minimising disruption to the surrounding area. Our transport team developed a sustainable transport and access strategy, integrating the site seamlessly with the surrounding infrastructure and supporting the planning submission. Transport strategy and access We also managed the design and construction of the basement substructure, incorporating additional car parking facilities within the tight site constraints. Our transport team developed a sustainable transport and access strategy, integrating the site seamlessly with the surrounding infrastructure and supporting the planning submission. Ground engineering and foundations Given the building’s location on a constrained site within the city centre, our civil engineering team worked closely with the design team to overcome the complexities of foundation and basement design, ensuring the building’s stability while minimising disruption to the surrounding area. This involved detailed geotechnical assessments to understand the ground conditions and ensure that the building’s design could accommodate the cave network beneath the site. Sustainable design support This approach enabled us to deliver a highly efficient structure that met the client’s specifications and sustainability targets. Our transport team developed a sustainable transport and access strategy, integrating the site seamlessly with the surrounding infrastructure and supporting the planning submission.
