12d helps rebuild Christchurch - Stronger Christchurch Infrastructure Rebuild Team

ClientSCIRTLocationNew Zealand

Project Summary

The $2 billion rebuilding of Christchurch is one of the biggest and most complex civil engineering projects New Zealand has ever seen.

The city was hit by four major earthquakes over 10 months, the magnitude 6.3 quake in February 2011 being the most destructive.


The Challenge

The earthquakes resulted in the loss of 181 lives, and caused unprecedented damage that left the 376,000 residents without even basic infrastructure and services.

The massive rebuild task has started, and the design teams at work on restoring the devastated infrastructure needed to choose the right civil software.

The Solution

They chose 12d Model -- because it provides the best integrated package for surveying, preliminary and detailed design, construction and producing as-built drawings.

The project is being carried out by the Stronger Christchurch Infrastructure Rebuild Team (SCIRT), an alliance involving Christchurch City Council, Canterbury Earthquake Recovery Authority (CERA), New Zealand Transport Agency (NZTA), City Care, Downer, Fletcher Construction, Fulton Hogan, and MacDow New Zealand. It will also see major involvement from GHD, URS, Sinclair Knight Merz, Beca Opus and Eliot Sinclair.

And 12d Model will be helping the SCIRT teams across the alliance tackle a huge amount of work, in a project that will take at least five years.

An estimated $2.5 billion worth of replacements or repairs are needed to more than 200km of roads and 800km of pipes for water, wastewater and stormwater, as well as a large number of water reservoirs, bridges and public parks.

"12d Model is being used as the civil engineering database and for all the civil engineering functions including the surveying, drainage and sewer design and road design," 12d Solutions Managing Director Lee Gregory said.

To help with the vast rebuild effort, 12d NZ are currently conducting "train the trainer" courses for drainage and civil design, and training for the SCIRT 12d Lead Designers.

"All the surveying is being done for SCIRT by consultants using 12d Model," he said.

The Result

New Zealand government Earthquake Recovery Minister, Gerry Brownlee, said Canterbury had been amazingly resilient over recent months, with residents willing to make changes to meet the challenges of the devastated areas.

"Through earthquakes and snowstorms the city is still getting up and going to work," Mr Brownlee said.

"Despite all they‘ve been through I believe confidence is growing among Cantabrians, and with good reason."
