Completed in January 2024, Hanevo delivered this design and build project to replace two end-of-life Air Handling Units serving the Special Baby Care Unit and Isolation Room at Epsom General Hospital.

The works were undertaken within a live hospital environment, with extensive liaison carried out with ward teams and clinical stakeholders to minimise operational disruption and maintain critical patient care provision throughout the programme.



The project included enabling works to bring a maternity theatre into clinical compliance to support temporary decant arrangements during the replacement programme.

Works included:

• Air flow testing and monitoring works to decant theatre spaces
• Medical gas installations including AVSU, pipework and alarm systems
• UPS equipment, containment and cabling installations
• Hygienic wall cladding and vinyl flooring installations
• Design and installation of temporary steel support structures for retained AHUs
• Sectional removal and replacement of AHUs within constrained plant spaces
• Adaptations to retained ductwork, pipework and electrical infrastructure
• Duct cleaning and installation of new fire and smoke dampers and controls equipment
• BMS modifications, air flow testing and pressure environment balancing
• Structural steel support installations to roof mounted AHU systems
