Weather Protection for Hospital Roof Replacement | UK

A live hospital roof replacement requiring uninterrupted operations

A major redevelopment project at a live hospital required the full replacement of a roof structure over a critical operational area. The works formed part of a wider programme addressing structural issues, while ensuring that essential hospital services remained fully operational throughout.

The project presented a number of challenges. The roof layout was complex, with multiple interconnected buildings, and the site included sensitive areas requiring uninterrupted access. Maintaining safety, weather protection, and operational continuity was critical, particularly in an environment where disruption could impact patient care.

Traditional approaches using scaffolding and sheeting were considered, but these would have introduced significant logistical constraints, extended installation times, and increased disruption to ongoing hospital operations.

A modular weather-protection system installed at height

Njordair supplied a modular Constant Air system configured to create a fully enclosed, weather-protected working environment across the active roof areas.

The system was installed at height and deployed in sections, allowing works to progress in a controlled and flexible manner. Individual modules could be rapidly inflated, repositioned, and adapted as the project advanced, without the need for extensive alterations to supporting structures.

The lightweight and modular nature of the system enabled installation in a complex rooftop environment, while maintaining access to critical areas of the hospital. Integrated access points supported safe movement of personnel and materials throughout the works.

This approach provided a significantly more agile alternative to traditional temporary works, allowing the contractor to respond quickly to programme requirements while maintaining a consistent level of protection.

Weather-protected roof works with reduced disruption to hospital services

The Njordair system enabled the contractor to carry out roof replacement works within a fully weather-protected environment, while maintaining continuous operation of the hospital.

By avoiding the need for large-scale scaffold adaptations and reducing installation time, the system supported a more efficient and flexible programme. Works were able to progress without delays caused by weather or access constraints, while minimising disruption to staff, patients, and hospital services.

The modular design also allowed the system to be used continuously throughout the programme, adapting to different phases of the project without the need for repeated large-scale installation works.

For complex refurbishment projects in live environments, Njordair systems provide a practical solution for maintaining programme certainty, improving site logistics, and reducing disruption.
