Health New Zealand | Te Whatu Ora – Canterbury District invites suitably qualified and experienced contractors to submit tenders for roof flashing replacement and associated weathertightness works at Burwood Hospital, Christchurch.

The works address known water ingress issues caused by defective roof flashings, service penetrations, and associated roof interfaces.

The scope includes flashing replacement and upgrades, installation of dry pan flashings where required, localised roof repairs, roof surface preparation, application of protective coating systems, waterproof membrane installations, skylight repairs, and associated weathertightness remediation works.

The works are to be undertaken across the following buildings:
Building 1 – Ward HG (Spinal Unit)
Building 6 – Physical Medicine
Entrance and linkway between Buildings 6 and 4
Building 4 – Minor Surgery Unit
Building 13 – Maintenance Office & Workshop (lower roof areas only)
Building 9 – Ward GG (Surgical Services)
Building 5 – Old Administration Building

The project will be delivered under a Medium Works Contract and is based on a performance‑based specification. The Contractor is responsible for confirming the suitability and compatibility of proposed systems with existing roof conditions.

The requirement to achieve a weathertight outcome applies to the areas of work undertaken under the Contract and does not extend to rectification of unrelated or latent defects beyond those reasonably identifiable at tender stage.

All asbestos-related works are excluded and will be managed separately as an operational expenditure activity. The Champion Centre is excluded from the scope.

Burwood Hospital will remain fully operational during the works. Tenderers must allow for all health and safety, infection control, access, staging, and operational constraints associated with working in a live hospital environment.

Preliminaries & General (P&G) requirements must be clearly identified and priced separately.

Tenders will be evaluated using a price-quality methodology to determine overall value for money.
