Greenfield Development


Stockyard Falls Bulk Retail, Warkworth

CivilConstruction 400
Project management, detailed civil design, consenting and construction supervision for a bulk retail development.  Initial work included preparation of engineering documentation to support a plan change application to enable construction of the 8ha bulk retail centre.  Due to the sensitivity of the receiving environment, the development required a high degree of engineering input.  Particular detail was required for the development of an esplanade reserve between the bulk retail centre and the Mahurangi River, forming platforms for large footprints on sloping and variable topography and servicing the development with adequate utility infrastructure (stormwater, water supply and wastewater).  This involved developing engineering solutions based on architectural layout plans, including a wetland stormwater treatment pond, car park and building platforms, pressure wastewater systems, a variety of retaining wall systems, pedestrian walkways and landscaping.  Significant earthworks were required to prepare the site for development which included pre-loading to address settlement issues and building platforms within flood plains.  This work included extensive consultation with Rodney District Council and the Auckland Regional Council.


Countdown Supermarket, Waiheke

Countdown 400
Assessment of geotechnical, civil, environmental, and subsequent detail design for a supermarket with large basement car park and separate tenancies.  Work comprised geotechnical and contaminated site investigations, wastewater review, and detailed civil design, which included rainwater tanks, supplemented by a bore supply for the non-reticulated site.  Large underground tanks were required to provide storage for potable water, sprinkler tanks, and fire fighting (total volume 350m3).  With no public wastewater reticulation, detailed design and consenting of an on-site wastewater system was also completed.  Work included engineering support for a Resource Consent application, attendance at subsequent council hearing, detailed design, and assistance with tendering and negotiation with the contractor.  Work is currently underway.


Residential Subdivision, Lincoln

LincolnSubdiv 400
Geotechnical investigation, analysis, and reporting for subdivision consent for a large rural greenfield site. Investigations encountered variable ground conditions that required careful designation of land classification zones in accordance with the latest MBIE guidelines. Staging of the subdivision was carried out in conjunction with the gradual development of building platforms.


Hudson Road Business Centre, Warkworth
HudsonRd 400
Geotechnical evaluation and civil input for the development of a 13.2ha site as a retail and business complex.  The site is underlain by variable alluvial materials that are prone to differential settlement issues, and is traversed by streams of significant ecological value.  Assessment required preliminary engineering design to assess economic feasibility and provide supporting information to obtain a plan change.  Civil work involved a preliminary flood risk assessment; design of stormwater management and mitigation measures; assessment of public infrastructure capacity and future upgrades; and geotechnical and earthworks requirements.  The proposed staged development will have up to 60,000m2 floor area comprising a retail and business centre with large footprint buildings, trade industry, work units, car parks, and a petrol service station.

Subdivision, North Canterbury
NorthCanterburySubdivision 400
Geotechnical investigation and civil engineering design of stormwater infiltration and routing through a new 90-lot subdivision. Specialist assessment works were required to address potential flooding risks raised by the local council. Following the commissioning of a site-specific flood model, mitigation works were designed to direct potential surface water flow and provide a suitable freeboard to residential building platforms.
