methodology and safety procedures. After the Timaru
dome was completed, Domtec’s specialty equipment was
shipped to Auckland to build the 30 000 t cement storage
dome there. The Auckland dome required approximately
480 MT of rebar and roughly 1100 m³ of shotcrete.
(Downer, 2016). The dome structure stayed on schedule and
was completed in 14 weeks from inflation of the air form to
the final layer of shotcrete.
Working in foreign countries can sometimes present
challenges, especially when Domtec’s unique type of
construction is unfamiliar to local building officials. Downer
has a solid reputation in New Zealand and was careful to
‘de-risk’ as much as possible by working with local officials.
Downer also worked closely with Domtec to create specific
methodology and safety controls, and set up a workshop
with WorkSafe NZ, the government’s health and safety
regulator. The presentation was accepted the first time
without any comments or changes.
Overall, the two 30 000 t cement storage domes
were built on-time and Domtec proved to be a suitable
supplier to Holcim’s chosen general contractor, Downer.
This project marks the first two concrete domes in New
Zealand and has overall been well received.
