Engineering better environments for a better future
"It's not only what we do, it's why we do it"
All of our engineering services are multi-disciplinary. Our experienced civil engineering consultants are trained in everything from feasibility analysis right through to construction management and certification. Each engineering project’s strategy is tailor made to suit the client’s individual needs, budget and timeline.
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.
Our Civil Engineering department draw on the different project experiences each employee has to make sure our proposed solution is the right one. Our team collaborates daily and we encourage peer reviews at all relevant stages of a project. Outside of work we are an active team, attending barbeques, marathons, mountain bike rides to name a few. This keeps our minds sharp and ready to work on your project.
Terra's engineers are all members of Engineering New Zealand
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.
Carry our 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.
This branch of civil engineering looks at the maintenance and ongoing development of the local water supplies.
Terra Consultants are specialists in the following:
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
Residential, Commercial & Industrial Development 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.
Assessment of environmental effects
This 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.
Civil Drafting & Drawing 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.
Applications for 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.
Engineering Plan Approval
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.
Professional 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.
FLOOD & OVERLAND FLOWPATH ASSESSMENT REPORT
To support Resource Consent
This report provides recommendation for minimum finished floor levels and input for overland flowpath management within the site.
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 tenderes. The Client will receive a tender analysis report with recommendations.
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.
Administration over contracts and certification
We will undertake the construction administration, claims processing and reporting. TERRA Consultants Ltd 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.
To support the engineering & land development teams
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.
Section 224(C) Certification
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 inspection and Certification as required. We will prepare application to Council for certification and survey of 224c Certificate to your solicitor.
CASE STUDY - PUMP STATION
Terra Consultants were engaged on behalf of the Cosgrave Land Owners Group for the upgrade of the Grove Road Pump Station, Takanini. This will ultimately service approximately 1000 dwellings adjacent to Grove and Cosgrave Roads. The upgrade involves replacing existing pumps and electrical gear plus the installation of 200m3 of underground overflow storage. The pump-station upgrade works have a value of approximately $2M.
The project works are complicated by the existing pump station being in continuous operation and the new storage tanks is required to be installed 5m below the surface in soft peat.
