About this service

Infrastructure & Subdivision Engineering

At GDC Group, we provide integrated infrastructure and subdivision engineering services for residential, commercial, industrial and mixed-use developments across New Zealand. From early feasibility and master planning through to detailed design, approvals, construction and completion, we work with clients and project teams to turn development opportunities into practical, consentable and deliverable projects.

Our multidisciplinary approach brings together civil, structural, geotechnical, transport, surveying, planning and three waters expertise to provide coordinated solutions throughout the development process.

Development Feasibility

Understanding whether a development is technically and financially viable is critical before significant investment is made.

GDC Group can provide early-stage engineering and infrastructure advice to identify opportunities, constraints and potential development requirements.

Our feasibility assessments can consider:

  • Site constraints
  • Topography and existing conditions
  • Geotechnical considerations
  • Existing infrastructure
  • Three waters capacity
  • Stormwater requirements
  • Roading and access
  • Earthworks requirements
Show 4 more
  • Development staging
  • Infrastructure upgrades
  • Easements and servicing constraints
  • Consenting considerations

This early advice helps clients understand the engineering implications of a site and make informed decisions before progressing into detailed design.

Infrastructure Planning & Master Planning

Well-planned infrastructure provides the foundation for successful communities and developments.

We develop infrastructure strategies that consider both the immediate project and the wider development context, including future stages and potential growth.

Our infrastructure planning can incorporate:

  • Water supply
  • Wastewater
  • Stormwater
  • Roads and access
  • Earthworks
  • Utilities
  • Open space and public infrastructure
  • Development staging
Show 1 more
  • Future infrastructure requirements

By considering these elements together, we can develop infrastructure solutions that are coordinated, efficient and capable of supporting long-term development.

Subdivision Engineering

GDC Group provides engineering support throughout the subdivision process, from initial site assessment through to construction and completion.

Our subdivision engineering services can include:

  • Preliminary subdivision investigations
  • Site servicing assessments
  • Lot layout and development planning
  • Road and access design
  • Three waters design
  • Stormwater management
  • Earthworks design
  • Retaining solutions
Show 6 more
  • Utility coordination
  • Infrastructure upgrades
  • Construction documentation
  • Council liaison
  • Construction support
  • As-built information

Our engineers work closely with surveyors, planners, architects and other specialists to ensure subdivision designs are coordinated from the outset.

Three Waters & Stormwater

Effective three waters infrastructure is fundamental to sustainable development.

Our multidisciplinary engineering capability allows us to plan and design:

  • Stormwater networks
  • Stormwater treatment and management
  • Water supply networks
  • Wastewater networks
  • Pump systems where required
  • Drainage infrastructure
  • Development connections
  • Infrastructure upgrades
Show 1 more
  • Catchment and capacity assessments

We consider both site-specific requirements and the wider network to develop practical infrastructure solutions.

Low-Impact & Sustainable Development

Modern developments need to consider how infrastructure interacts with the natural environment.

GDC Group incorporates low-impact development principles where appropriate to help manage stormwater, reduce environmental impacts and support more resilient developments.

Solutions may include:

  • Water-sensitive design
  • On-site stormwater management
  • Infiltration and attenuation
  • Stormwater treatment
  • Natural drainage approaches
  • Reduced impervious surfaces
  • Sustainable infrastructure strategies

Our aim is to develop solutions that are practical, technically appropriate and suited to the characteristics of each site.

Earthworks, Erosion & Sediment Control

Earthworks can significantly influence the performance, cost and environmental impact of a development.

We provide engineering support for:

  • Bulk earthworks
  • Cut and fill assessments
  • Earthworks planning
  • Site grading
  • Platform development
  • Retaining requirements
  • Erosion and sediment control
  • Construction staging
Show 1 more
  • Stormwater management during construction

We consider earthworks alongside geotechnical conditions, stormwater, access and infrastructure requirements to achieve efficient site development.

Construction Support & Contract Administration

Our involvement does not end when the design is complete.

GDC Group can support clients throughout construction to help ensure infrastructure is delivered in accordance with the approved design and project requirements.

Services can include:

  • Construction observation
  • Site inspections
  • Technical support
  • Design clarifications
  • Contractor coordination
  • Progress assessments
  • Variation reviews
  • Quality and compliance observations
Show 3 more
  • Contract administration
  • Practical completion support
  • As-built documentation

This provides continuity from design through to delivery and helps address issues efficiently as they arise.

Integrated Development Engineering
GDCGDC Group · Infrastructure & Subdivision Engineering

Integrated Development Engineering

Land development rarely involves a single engineering discipline.

GDC Group brings together:

  • Civil engineering
  • Structural engineering
  • Geotechnical engineering
  • Transport engineering
  • Surveying
  • Three waters engineering
  • Stormwater engineering
  • Architectural design
Show 1 more
  • Planning and consenting

This integrated capability allows project constraints to be identified early and solutions to be developed collectively rather than in isolation.
