Houses in Progress

What do you do with 7,000 old state houses that are no longer fit for purpose? That’s the problem Piritahi and asset owner Kāinga Ora began grappling with when the Piritahi Alliance was established in 2018 and the answer is a four-stage solution called the Piritahi House Removal Programme.

Piritahi is charged with removing old state houses across nine neighbourhoods in Auckland, remediating the land, upgrading the infrastructure and then handing the land asset back to owner Kāinga Ora to build 25,000 new, warm, dry homes on.

 

From the outset, our client Kāinga Ora set a target of 80% of materials in a house to be salvaged for recycling. We are currently exceeding that, recycling 92% of materials by relocating many homes for reuse elsewhere and recycling all of the materials that we are currently able to.

 

Between January and November 2021, we diverted 12,300 tonnes of construction waste from landfill. This equates to a diversion rate of 87% which is 7% above the target Kāinga Ora set for us. Over the same period, we relocated 124 homes which means we have relocated 31% of all homes that we have removed since the start of the project in 2018. That’s 23% above the target.

 

What is Piritahi’s four-stage programme?

Relocate – move the whole house to another location for use in its entirety

Recycle – separate materials for re-use (joinery, furnishings, wooden flooring, cladding, sinks, benches etc), segregate materials for recycling (metals, aluminium, concrete)

Recovery – chip wood for energy/burning

Remainder – sent to landfill (Material that is contaminated with asbestos or lead has to be disposed of appropriately. Asbestos and lead paint were commonly used in the construction and maintenance of many of the old statehouses. The other materials from these houses that end up in landfill do so because they aren’t able to be recycled or reused at this time – most notably insulation, polystyrene and fibre cement.

The Piritahi House RemovalProgramme is already having a significant and profound positive impact on the environment and will continue to do so during its lifespan – this is something that Auckland Council encourages.

That’s because sending construction and demolition waste to landfill creates environmental problems for Auckland. Auckland Council vision is ‘Zero waste by 2040.’ To achieve this, the council has a long-term target of reducing total waste to landfill by 30% by 2027. As Auckland’s single largest waste stream, with high tonnages going to landfill and high diversion potential, construction and demolition waste has been identified by the council as a priority waste stream to achieve theWaste Management and Minimisation Plan’s target. The Piritahi House Removal Programme is making a very real and tangible positive contribution to the Council’s target.

What tech does Piritahi use to manage the House Removal Programme?

Before land can be transformed into build-ready Superlots thousands of houses need to be removed. For this, our construction teams need real-time visibility over the status of each house with up to the minute information on the home – whether it is occupied, vacant, services disconnected and contamination status.  This is the critical path that exists in the house removal process.

 

The management of the complex pathway in the House Removal Programme relies heavily on multi-disciplinary collaboration. This is achieved through a family of GIS apps created by Piritahi GIS specialists Andrew Flaws andGabriela Olekszyk. The GIS system combines web and mobile mapping apps, analytics dashboards and the security of centralised automated reporting.

 

The complexity of the process in the end simplifies the outcomes and has earned Andrew and Gabriela a finalist place in the prestigious regional APSEA Spatial Awards. The process makes for a seamless removal of not only each dwelling, but multiple dwellings in a manageable sequence.

Andrew Flaws and Gabriela Olekszyk are finalists in the Asia Pacific Spatial Excellence Awards for their revolutionary work with GIS Apps that manage the successful House RemovalProgramme.

The successful collaboration between many moving parts in theHouse Removal Programme means more houses are able to be relocated for other families to use and thousands more tonnes of decontaminated building material are being recycled for reuse in the circular economy. The winner is the environment as the Alliance smashes its sustainability targets in the preparation of ready-build land for Kāinga Ora to build new and modern warmer homes.

 

The Construction Sector Accord recently published a ‘How to guide” from Piritahi on saving and relocating homes. It outlines what category of house can be relocated because not all of them are able to be (mostly due to age or construction materials), you can read more about this HERE.
