Engineering design and consulting services for medical facilities

Our building experts have assisted in designing and constructing a broad range of types of health infrastructure around the world, from public hospitals to remote rural purpose-built treatment centres. It is essential that these medical facilities adapt to the rapid changes in medical technology and healthcare provision guidelines. Ayesa has been involved in creating new hospital facilities and in the adaption and rejuvenation of existing hospitals.

Repurposing and adapting buildings is an integral part of sustainable development. Much of Ayesa’s experience in this sector has been in relation to several developments at St Bartholomew’s Hospital in London, the oldest functioning hospital on the same site in the world. In 2002, Ayesa was engaged by Skanska to provide structural engineering advice on the ‘Retained Estate’ for the redevelopment of two hospital sites, St. Bartholomew’s Hospital and The Royal London Hospital, and to assist them in securing their ultimately successful bid for this PFI project valued at £1 billion. For the past 25 years, our teams have been working at St Bartholomew’s on a series of developments that include the West Wing, the new King George V Wing, RSQ and OPD, with work on the new Private Patients Unit (PPU) commencing soon. Our expertise in conservation and structural engineering, along with our long-standing working relationship at St. Bart’s, helps us to deliver projects for our clients with lasting impacts. Our work has linked the 900-year-old past of St Barts to the present, delivering modern, light-filled, patient-centric spaces.

Notable Projects include:

New Children's Hospital Dublin - our consultancy services covered design methodology, monitoring, and detailed design of the secant pile wall (approximately 960m in length) and temporary support to the wall during construction of the €2bn New Children’s Hospital. This state will consolidate and modernise paediatric hospital care for Dublin's capital city in Ireland.

The White Lodge - an award-winning purpose-built treatment centre for children with cerebral palsy in Worplesdon. Recipient of the Better Healthcare Special Judges Award.
