Christchurch Earthquake response

Scope of Project Following the major earthquake on 22nd February 2011, Christchurch was in a State of Emergency, with urgent works required throughout the city. SuperSealing were proven performers after successfully completing 2 work programs for the City.

SuperSealing’s task was to help prevent road and pathway erosion that had suffered extensive wash away damage, by providing crack sealing services prior to the imminent wet season.

Safety of work was a major concern, so SuperSealing was also required to carry out Traffic Management for their own work, and also traffic management for a number of other contractors including drain cleaners and other infrastructure contractors.

Planning The Earthquake Commission deemed that no work could start for 3 weeks after the earthquake. This time was used to plan and organise the required resources which included equipment and also personnel.

All personnel were briefed prior to deployment to ensure a safe and quality job was carried out in extreme conditions with aftershocks continuing each day.

Due to the extraordinary nature of the disaster, there were big rips in the road and extensive cracking throughout the City that required repairing.

Allocation of Resources

  • 3 Traffic Management vehicles

  • 7 Traffic controllers

  • 7 Crack Sealing Operators

  • 3 Crack Sealing Units

Outcome The 3 Crack sealing units worked 21 hours per day for a 10 week period. Large rips in the road were repaired by packing cold mix asphalt into the big divisions in the road and then using our rubberised crack sealant over the top.

Traffic management crews effectively worked with multiple contractors throughout the City with no incidents or accidents. Due to the Controllers doing great work, more contractors requested our services and we grew from one traffic crew to four.

By June 2011, there were over 3500 aftershocks with an average of approximately 3.5 on the Richter scale. This presented challenges to the individuals working there, having to handle the continual movement whilst concentrating on delivering a quality service.

The crews successfully worked tirelessly in the difficult conditions throughout the project and this work is projected to be ongoing for the foreseeable future due to the extensive damage and good work the crews have done.
