What the experts say..

Stevensons Test results –

Stevenson Laboratory Ltd completed a full suite of NZTA M4 Basecourse specification tests finding …..

“The Wards RCC AP40 aggregate at the density tested is above average performance for the dry/drained test and well above average performance for the saturated/undrained test (note: all unbound aggregates perform poorly in the saturated except the Wards RCC AP40 showed exceptional performance).” WME Magazine 2009 Edition –

Where to from here?

Council have sanctioned research into this topic having Synergine head up the project of investigating whether RCC could be used in roading

  • n behalf of Auckland Transport.

The Road to recovery article after research provides RCC; Environmentally lowers a carbon foot print on greenhouse emissions Is highly cost effective option – 22 years life of Virgin rock vs 447 years life RCC – 20% cheaper giving customers more material for the tonne “The impact is overall sustainability to a large infrastructure project.” We need this, we need to encourage initiatives that provide better

  • ptions for recycling in our industry of building infrastructure both in

roading and other large projects.

Sending out the message - Waste Management

  • In partnership with Auckland Council we set out to

redefine what ‘waste’ meant to the project team. Focusing

  • n deconstruction
  • We understood the need to provide a clear and

fundamental message.

  • Throughout pre-start meetings, toolbox talks, review

meetings we emphasised the basic principle of waste hierarchy.

Adopting a Waste Hierarchy

august 2013

As we engaged staff and communicated the hierarchy of waste, we developed detailed systems as part of our Environmental Management Plan.

Reuse items to the Community

August 2014

In collaboration with Auckland Council and Ecomatters, 29 ton of deconstructed items such as thermal insulation, book shelves, cupboards, furniture, hot water cylinders were transported to Henderson Waste Transfer Inventory was created and items provided at a very small cost to the community Example: A Kaitaia community group who purchased a large amount of furniture for their offices

Reuse items for 135 - Existing luminaires

august 2014

2443 light fittings = 3.9 ton of recyclable material Made up of = diffusers, control gear, wiring, plastic & tubes

4 ton of reuse i.e. steel casings

Reuse items - Insulation

august 2014

As a means of working leaner, we sorted, bagged and weighed the insulation whereby creating a more attractive prospect for ‘reuse’.

Reuse items - Glass Partitions

August 2014

 As part of our deconstruction we removed the existing glass partitions.  Safely stored on B4 ready for reuse within 135 Albert Street.  The finished reuse product as glass mark-up panels as shown above.
