FRED TAYLOR DRIVE INTERSECTION

CLIENT: HUGH GREEN GROUP

JUNE 2024 TO SEPTEMBER 2025

Redevelopment of Fred Taylor Drive involved widening the existing road corridor from two to four lanes to both sides of Spring Garden Avenue, providing access to the Redhills Raphoe development and including approximately 100m of local road into the development.

Additional works include relocation of existing services, street lighting upgrades, drainage upgrades, landscaping, intersection signalisation and raised median construction.

This project was located in a high-traffic environment, requiring the implementation of a robust and a comprehensive Traffic Management Plan (TMP). This plan was developed in close coordination with Auckland Transport to ensure minimal disruption to the public and surrounding businesses while maintaining a safe worksite.

Key traffic control measures included the implementation of temporary speed restrictions, strategic shoulder closures, controlled capacity reductions, and clearly marked pedestrian diversions. A qualified Site Traffic Management Supervisor (STMS) was present on-site at all times to oversee operations and ensure full compliance with the approved TMP and all associated safety protocols.

Wharehine completed the works ahead of schedule as a result of careful programme management, skills and resource allocations. The client Hugh Green Group gave us high praise for this accomplishment.

METLIFECARE MANGAWHAI - PHASES A & B

CLIENT: METLIFECARE LTD

OCTOBER 2024 TO FEBRUARY 2026

Wharehine Construction delivered a comprehensive civil works package for phase A of the Metlifecare Mangawhai development, beginning with full site clearing and extensive bulk earthworks to prepare the land for construction. The team completed both private and public roading, removed an existing wastewater line, and installed new public and private drainage systems. Utility services were laid within a common services trench, alongside works to support the Chorus public network and a private fibre network for internal comms (nurse calls, security cameras, etc). The project also included constructing retaining walls, upgrading the existing council stormwater pond to improve capacity and performance, and building a new potable water pump-house equipped with water storage and pump systems to service the development.

Works are now underway with Phase B for remainder of earthworks and civil works for the project. This also includes finishing works of asphalt, footpaths and ROW’s for Phase A. The project is aiming for completion in November 2026.

RODNEY STREET FOOTBRIDGE AND FOOTPATH

CLIENT: AUCKLAND TRANSPORT
MARCH TO DECEMBER 2024

The Rodney Targeted Rate project extended the footpath along the eastern side of SH1 in Wellsford, it was an important pedestrian and cyclist connection from Rodney Street to link up to all the town sports grounds which are situated on Centennial Park Road.

The full extent of the works included 645m of new footpaths, new pedestrian footbridge, residential vehicle crossings, drainage improvements including catch pits, manholes, subsoil drains and pipework, underground services, streetlights, kerb and channel installation & pavement construction.

The footbridge construction consisted of a 36m single span precast concrete Super-T over the North Auckland Rail Line (NAL) to the north side of the existing Wellsford railway overbridge. The abutment construction contained 15m deep piling and construction of concrete abutment beams, curtain walls, wing walls and back walls to form support and access onto the bridge. Timber retaining walls were also constructed to form the tie-ins to the bridge abutments.

During the bridge girder placement, SH1 had to be closed with a short detour for nightworks involving a tandem crane lift with 2 x 450tonne cranes set up on SH1 to lift the 80tonne girder into place. The complexity of the works required experience and expertise to carry out safely and effectively in order to work around the existing high capacity overhead services and ensure the critical lift programme was met.

This complex project was meticulously planned and carried out successfully without issue or delay. Multiple suppliers, subcontractors and service and utility providers were involved and coordinated via a well-executed communication plan which also involved a number of local stakeholder groups.

MATAKANA LINK ROAD / TE HONOHONO KI TAI

CLIENT: AUCKLAND TRANSPORT
2019-2023

The Matakana Link Road (MLR) project was a 1.35km greenfield road between State Highway 1 (SH1) and Matakana Road in Warkworth. Warkworth has been
identified as a Satellite Town with over 1000ha of future urban zoned land.

Over the next 30 years these future urban areas are expected to accommodate approximately 7,500 additional dwellings, or an additional 20,000 people. The MLR project will improve resilience of the transport network by providing an alternative route to the busy Hill Street intersection, and also facilitate planned growth in the Warkworth area as identified by Auckland Council’s Warkworth Structure Plan and the Supporting Growth Alliance transport network. The project will form one piece of the overall future transport network for Warkworth. In particular, it connects to the New Zealand Transport Agency’s (NZTA) Puhoi to Warkworth (P2Wk) project, and the future Western Link and Sandspit Link Roads. The job involved over 200,000 cubic meters of earthworks along with construction of 4 lane roading, drainage, services, footpaths, cycleways, lighting a 3 span bridge culminating in the tie in roundabout on Matakana Road.
