State of the art healthcare
The new Acute Services Building at the Christchurch Hospital is a vital piece of infrastructure for the city, and a project demanding some clever engineering in a tight programme. Holmes was brought in for structural and civil engineering on the strength of our extensive healthcare expertise and our ability to deliver a robust, resilient design appropriate for Christchurch’s extremely challenging seismic environment.
We applied the principles of Low Damage Design to underpin the continuity of this Importance Level 4 structure which is base isolated—providing the necessary post-disaster resilience for the region and local community. Particular care was taken to ensure the appropriate seismic detailing was consistently applied to the building services, fit-out and contents, to mitigate damage during earthquakes.
The redevelopment is being undertaken within the context of a busy working hospital campus—putting extra emphasis on designs that are easy to construct, creating minimum disruption. The steel moment frame structure was designed to be prefabricated in sections and bolted together on site. The requirement for site welding and work on site has been minimised, meaning the onsite programme is far more efficient. The steelwork has also been designed such that elements can be easily transported by road or ship. This has given the contractor flexibility in the location of fabrication, allowing the structural cost to be minimised—an important saving in a big ticket, high profile project.
We’re delighted to have had the opportunity to make such a strong contribution to a building so critical to Christchurch’s future.
