Christchurch Earthquake Emergency Response & Infrastructure Recovery

Share on:

The Christchurch earthquakes in 2010 and 2011 caused damage to almost 50% of the city’s urban roads. This equates to 895km of Christchurch’s road network, which has suffered damage necessitating not just repair, but rebuilding. However, a greater immediate challenge for the Christchurch City Council lay in repairing and rebuilding key strategic road links for emergency response vehicles and vehicles delivering life-dependent supplies, such as clean drinking water.

The Infrastructure Rebuild Management Office (IMRO), and subsequently the SCIRT Alliance, appointed GHD as the preferred partner to deliver the remedial works.

GHD systemised the removal of widespread liquefaction from Christchurch’s urban roads, with the development of a new electronic database to record, monitor and manage the total tonnage of liquefaction removed. Our team executed scoping reports and road condition assessments, which aided an accelerated council process to effectively determine the extent of damage to the city’s roading corridor.

GHD prepared concept reports to propose remedial repairs, with an assessment of the damage, analysis of treatment options and cost estimations.

Along with detailed design proposals, our team co-ordinated surveys where required, supervised construction works to budget and specifications as agreed and delivered integrated work packages across roads, along with the three water disciplines of potable, sewage and storm water.

Our existing relationship with the Christchurch City Council enabled a rapid response and action from our team, with an established knowledge base of the council’s technical design standards, systems and processes.

Extensive support from GHD teams all around NZ ensured the deployment of specialist personnel and equipment to Christchurch at a moment’s notice. In turn,GHD’s global network of international resources filled gaps arising as a result in projects operating in other areas of the country.

Economic and population growth, greater urbanisation and increased mobility are boosting demand for new infrastructure and services straining the capacity and effectiveness of existing assets. Single mode approaches are no longer viable as governments and stakeholders recognise the need for multi-modal solutions across the whole integrated network.

Across the whole transport spectrum of airports, maritime, roads and highways, rail bridges and logistics, our team provides integrated transport services throughout the project lifecycle - from initial policy, transport planning, economics and business case advice, through concept, procurement, detailed design and construction to operations, maintenance and asset management.
