Client: Stoford Developments Severn Trent Headquarters is a seven-storey, 170,000 sq ft office building located in Coventry, designed to accommodate up to 1,700 employees. Developed with Stoford, it was built to reduce operational costs while creating a modern, sustainable workplace. The structure’s two wings are arranged around a central atrium, encouraging collaboration. The building achieved a BREEAM Excellent rating and an EPC rating of B. Services we provided Digital Engineering & BIM Civil & Infrastructure Engineering Geotechnical & Ground Engineering Ground Investigation & Land Quality Structural Engineering Transport Planning & Traffic Engineering Water Engineering & Flood Risk Show More Our Role BWB was engaged as the principal engineering consultant for the Severn Trent Headquarters, providing a comprehensive range of civil and structural engineering services that were crucial to the project’s successful delivery. Our involvement began with the development of a robust structural design for the building, utilising post-tensioned concrete slabs for the office floor plates and in-situ concrete floors for the car park. Structural design Our involvement began with the development of a robust structural design for the building, utilising post-tensioned concrete slabs for the office floor plates and in-situ concrete floors for the car park. These elements were engineered to not only meet architectural requirements but also to offer flexibility for future adaptation. Detailed investigations In addition to structural design, our geo-environmental team conducted detailed site investigations to assess the viability of developing on a complex brownfield site. This process identified several challenges, including existing adjacent buildings, highways, and utility services. We prepared a comprehensive constraints plan and employed innovative methodologies to quantify and mitigate the abnormal costs associated with these engineering challenges. Bespoke solutions We also developed bespoke solutions for managing interactions with adjacent infrastructure, including a detailed approach to securing the foundations while minimising disruption to surrounding areas. Additionally, complex negotiations were required for Section 278 agreements to facilitate off-site highway improvements.
