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 on 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 options for recycling in our industry of building infrastructure both in roading and other large projects.

Waste and Deconstruction
Management
AUGUST 2014
Sending out the message - Waste Management
• In partnership with Auckland Council we set out to redefine what ‘waste’ meant to the project team. Focusing on 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
AUGUST 2014
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
Removal of acoustic and thermal insulation.
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.
Reuse items - Lundia Shelving
august 2014
As part of our deconstruction we removed existing Lundia Shelving.
Safely dismantled and stored on B4 ready for reuse within 135 Albert Street.
The finished reuse product reassembled, cleaned and installed as shown above. 8.631 ton of Lundia Shelving.
Reuse items - Roller Blinds
August 2014
As part of our deconstruction we removed the existing roller blinds.
The finished reuse product reassembled, cleaned and installed as shown above. 1.88 ton of reuse blinds.
Recycling
AUGUST 2014
Recycling of Ceiling Tiles
august 2014
As part of our deconstruction we removed all of the existing ceiling tiles.
The ceiling tiles where then transported to Envirofert for recycling. Currently at 109.3 ton of ceiling tiles.
Recycling of Ceiling Tiles
august 2014
With new plant the recyclable recovery rate improved to 80:20 e.g. 80% recycling 20% landfill.
New plant 80:20 ratio
