Civil Engineering

​For excellence in engineering, you cannot choose better than Terra. We are industry leading specialists in civil engineering, structural engineering & environmental engineering – it’s the core of our business and what we do best.

Project Management

Project Management

Our project managers are experienced in managing multi-disciplinary subdivision projects with both in house and external consultants. We represent our clients to the council and other project stakeholders to deliver projects that meet time and budget expectations. Every project is different and will require some careful management to ensure a balanced outcome is achieved.

Feasibility & Concept Design

Feasibility & Concept Design

The first stage of many projects is to check that development is possible in terms of available infrastructure and council development controls. It is advantageous to know the potential issues of a site up front to avoid costly constraints during the detailed design or construction. We offer simple or comprehensive feasibility investigations into a site to unlock its development potential.

Preparing Flood Assessments

Preparing Flood Assessments

Some of the sites have been identified by the council as prone to potential flooding during heavy rainfall events. Our flood engineers are able to analyse the stormwater catchment for your site and predict the overland flow paths and flow depths to allow developments to proceed safely.

Infrastructure Assessment Reports

Infrastructure Assessment Reports

Every project lodged with council for a Resource Consent requires an Infrastructure Assessment Report (IAR) which needs to be prepared by a suitably qualified Engineer. Our expert engineers are able to compile this report for your project that fully describes the existing infrastructure and the modifications required to allow development.

Create Detailed Drawing Sets

Create Detailed Drawing Sets

Clear and detailed drawings are essential to illustrate the proposed works to the council and allow contractors to accurately price and construct from the plans. We have a strong team of experienced Computer Aided Design (CAD) operators that make the best use of the newest versions of drawing software. We are able to produce 3D images of your proposal and make 3D fly throughs to give a project overview for sales purposes.

Preparing Design Calculations

Preparing Design Calculations

To ensure our proposals will get approved by council and to be confident they will be fit for purpose, we provide detailed design calculations appropriate to the complexity of the project. Our engineers are able to utilise the latest computer softwares to quickly compute and present professional calculations for all aspects of the project.

Design Reviews on behalf of Council

Design Reviews on behalf of Council

We also assist the council as an approved sub-consultant in reviewing other consultants work for compliance. We are responsible for verifying their designs are compliant with the councils code of practice.

Civil Engineering Services

Design Services

Civil Engineers are paid to think about and calculate everything in the development stage; from balancing earthworks to utility layouts. Everything planned out until the start of construction is referred to as design. 

Civil Tender Documents

+ Schedule of Quantities
Terra will prepare a schedule of quantities based on approved Resource Consent and EPA plans. Preparation of specifications for a measure and value Civil Tender, as well as prepare an Engineer's estimate on the scope of works. We will allow for a review of received tenders and facilitate clarification and negotiation with tenders. The Client will receive a tender analysis report with recommendations.  

Administration over Contracts and Cert.

We will undertake the construction administration, claims processing and reporting. Terra shall also arrange for the contractor to undertake the compaction testing at the direction of the Geotechnical Engineer. Terra shall recommend to the Client a Geotechnical Engineer for the project and also ensure they are programmed to complete the necessary geotechnical certification and geotechnical completion reports at the right time and for 224C. 

Drafting Services

This is an extremely important aspect when looking at the layouts of buildings in a subdivision, the levels of a new road, or any other major projects that will require engineering. Terra's accuracy and precision in all of our technical drawings are extremely beneficial and important for our clients. 

Building Consent

Terra has close connections and experience with Council which can potentially fast track the process. We can provide all of the professional advice necessary to get your building consent approved. 

Flood and Overland Flow Assessment Report

This report provides recommendation for minimum finished floor levels and input for overland flowpath management within the site. 

99 Grove Road

Each project's strategy is tailor made to suit the client's individual needs, budget
and timelines.

Engineering Plan Approval (EPA)

Preparation of plans, design, construction drawings and specifications of civil engineering works for infrastructure that will be vested to Council, i.e. infrastructure that will become 'public' and under the control and responsibility of Council.

AEE Assessment

An Assessment of Environmental Effects (AEE) must accompany your application for resource consent. Terra Consultants will prepare a written report which identifies the impact that your activity might have on the environment. 

Section 224(C) Cert. 

 You need an s224c certificate to request a 

Record of Title from Land Information New Zealand. An s224c certificate from Auckland Council confirms that a survey plan has been approved under s223 for the subdivision and that all subdivision conditions have been met. Terra will liaise with contractors and obtain as-builts (by others) and compile all documentation supplied. We will complete the inspection and certification as required. We will prepare application to the Council for certification and survey of 224c Certificate to your solicitor. 

Site Supervision

During the construction period, Terra will supervise the civil works to ensure that the works are undertaken according to design and to the required standard of Council. This certifies that the work completed is carried out to the highest standard. Terra's supervisors will actively ensure that the agreed plans match the work being carried out on site. 


Licensed Cadastral Surveyors to support the S.223 and S.224c process. As well as undertake necessary scheme plan preparation and topographical surveys on site at Resource Consent stage.

Traffic Assessment Report

The Traffic Assessment Report typically supports development applications for Resource Consent. It involves research for existing road and transport situations at the site and review of plans. The Traffic Engineer will provide a tracking curves assessment and plans. as well as advice to the planning and architectural teams. TIA report and RD assessment against the E27 assessment criteria will be provided. 


Water Supply

We look at the maintenance and ongoing development of the local water supplies.

We specialise in:

  • Reservoirs and Tanks;

  • The supply and demand of water;

  • Water storage reporting;

  • Pipe installation methods;

  • The treatment and reticulation of water mains (rural and urban;)

  • The storing and sourcing of water for communities



  • Carry out catchment analysis to determine existing stormwater run off flows during various storm events.

  • Predict possible upstream development – Maximum Probable Development (MPD)

  • Calculate flows generated from new impervious areas

  • Assess the existing council reticulated stormwater network for capacity.

  • Design stormwater storage (detention/retention) on site to reduce the stormwater discharge quantity.

  • Design Low Impact Design (LID) methods of achieving stormwater quality and quantity control e.g. ponds, wetlands, swals.

  • Propose methods of achieving the council required Water Quality (WQ) dependent on the type of proposal.

  • Design the layout and levels of new gravity pipe systems.


Council Liaison

Terra Consultants will discuss development feasibility with the council in the earlier stages of a project through the Pre-Application Meeting process. We can then compile and lodge the required documents for a Resource Consent (RC). We discuss and respond to any concerns council has under Section 92  of the Resource Management Act (RMA). We will review draft conditions to check for future issues. Post-approval, and if required/requested, we can apply to the council for changes to consent conditions/plans through Section 127 of the RMA.

After a RC is granted, we can further detail your proposal for the next council check; namely. Engineering Plan Approvals (EPA), Common Accessway (CAW), Building Consent (BC), Watercare Works Over Approval (WOA), and service/utility connection applications. We discuss and respond to any councils Request For Information (RFI) they have during these phases.

We have successfully completed a wide variety of projects for Local and Regional Councils including:


Terra Consultants are currently on the preferred supplier panel for Auckland Council. 



Our experienced civil engineering consultants are trained in everything from feasibility analysis right through to construction management and certification. 

All of our civil engineers, design professionals, structural technicians, environmental engineers and project managers are trained in the latest software and equipment. At Terra we like to stay on the cutting edge of industry technology – using engineering design software packages such as Land Development Desktop and AutoCAD Civil 3D.
