Description:

The Project seeks to provide better travel options, with upgraded road capacity, new walking and cycling facilities and improved travel reliability, access and safety.

The Project extends 8km between Papakura and Drury South connecting in with the Southern Corridor Improvements Project. The scope of the project includes, but is not limited to:

» Permanent widening of State Highway 1 to provide three 3.5m lanes and a shoulder north and southbound

» Interchange improvements, replacement of four existing bridges and improvements to two underpasses

» A separated shared walking / cycling path adjacent to the northbound traffic lane

» New local road connections

» To facilitate this scope extensive retaining and noise walls and culvert works will be required along the length of the project, along with the protection, modification and relocations of utility services.

» Upgrades to existing stormwater network improving resilience and providing 100% treatment of water falling within the motorway corridor.

Rating Highlights

Category Credits Achievements
Energy and Carbon Ene-1 (Lvl 1.55) Verified for an 5.5% reduction in GHG emissions compared to base case, attributed through a number of initiatives including, reductions in fuel for spoil movements, site office grid connections in place of on-site generators, programme efficiencies with Park Estate bridge demolitions, use of biodiesel for some plant, and use of solar powered lighting towers.
Water Wat-1 (Lvl 3) Level 3 was achieved with a 24.25% reduction in water compared to base case as a result of use of millings on haul roads and dust control polymers to limit need for water for dust control purposes.
Materials Mat-1 (Lvl 1.53) Verified for an 8% reduction in construction related embodied emissions from the use of 30% RAP content in 85% of the projects asphalt pavements and use of locally sourced aggregates (Drury Quarry Chip) which reduced transportation emissions.
Discharges to water Dis-1 (Lvl 2) Level 2 achieved with over 200 internal water quality checks taking place and an Auckland Council average compliance score of 1.08, the project had no adverse impacts on receiving water environmental values during the construction period.
Waste Was-2 (Lvl 2) Level 2 achieved with 100% of spoil, 96.3% of inert and non-hazardous material and 46.6% of office waste being diverted from landfill. Initiatives included reuse of asphalt millings for haul roads on the project and reuse of spoil to support adjacent subdivision developments.
Ecology Eco-1 (Lvl 3) Level 3 achieved with a 36.6% enhancement of ecological value using the NZGBC Ecological Value Calculator method. This enhancement was despite an increase in hard surface areas in a narrow project designation and was attributed to an increase in artificial waterbodies and native vegetation planted areas.
