A new LINAC bunker was constructed to accommodate advanced radiotherapy equipment and meet stringent radiation safety requirements. This project highlights the importance of purpose-built healthcare infrastructure in supporting cutting-edge treatment delivery and enhancing patient and staff safety. Procured via the Rise Framework, the project included net zero upgrades such as LED lighting, an eco-efficient chiller, and pipework insulation. Designed in accordance with HBN radiation safety requirements, the build featured a complex reinforced concrete structure to achieve shielding tolerances and required precision MEP coordination to accommodate specialist equipment and services. Challenges included maintaining service continuity in a live hospital environment, meeting programme constraints (e.g. fixed delivery for LINAC equipment), complex stakeholder coordination, infection control, and high technical accuracy in shielding. The project was delivered on time and within budget, with significant embodied carbon reduction through material selection and compliance with NHS net zero objectives.
