Bullendale is a large medium density housing project that comprises 17 three-storey apartment blocks utilising prefabricated light-gauge steel framing, Speedfloor panels and bathroom pods. Construction began in November 2018 and by combining these systems, the project is on track for completion in October 2019.

To meet the timeline of the project, a significant amount of preliminary planning was spent on the structural design. The design needed to be correct from the start to minimises the possibility of re-work and delays on site.

Speedfloor’s lightweight steel joist system has been specified for the suspended floors and sections of the roof. Adopting this over traditional construction has allowed for millimetre-perfect floors throughout the build thus far.

The Speedfloor sections and roof elements are constructed from light-gauge steel components that are manufactured in their Auckland factory. They are then transported to Christchurch where they are assembled into panels and delivered to site for placement onto the primary structure.

The accuracy and detail of the offsite constructed Speedfloor elements has reduced waste on site and enabled a super efficient build process. Bullendale’s prefabricated structure is scheduled to be completed on-site by June 2019. Additional on-site construction and fitting out is expected to be completed on schedule and within budget.
