Allenvale, Burnside Primary and Cobham Intermediate Redevelopment

Following the post-earthquake amalgamation of three Christchurch primary schools (Allenvale, Burnside, and Cobham), Protranz was engaged by Leighs Construction to undertake a complex civil works programme.

The project required constructing a new 20,000m2 campus while maintaining operations at the existing school – a delicate balance of progress and safety.

Our work included:

  • Bulk earthworks and building pad preparation
  • Asbestos removal from existing structures
  • Staged demolition of old buildings
  • Hard landscaping including car parks and footpaths
  • Construction of new recreational areas

Safe Asbestos Management

Our asbestos team expertly removed both known and newly discovered asbestos-containing materials (ACM), ensuring zero risk to the school community while maintaining project momentum.

Precise Demolition

Operating next to an active school required exceptional care. Our specialised demolition team employed controlled collapse techniques, pulling walls inward to ensure buildings fell into themselves. Materials were carefully sorted on-site and removed using sealed hook bins, maintaining the highest environmental and safety standards.

Strategic Staging

The project demanded careful coordination as new buildings needed to be completed and handed over in stages to allow the school to progressively relocate from existing buildings. This complex juggling operation was executed ahead of schedule and within budget.

Quality Finishing

The hard landscaping phase delivered exceptional results, including new car parks, concrete works, and recreational areas that will serve the school community for generations to come.

Environmental, civil and demolition excellence

The rebuild showcased our ability to handle complex, multi-stage projects in sensitive environments.

By completing the work ahead of schedule while maintaining stringent safety standards, we demonstrated our capability to deiver large-scale educational infrastructure projects without compromising the day-to-day operations of the school.
