Engineering better environments for a better future
 Civil EngineeringFor 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 ManagementOur 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 DesignThe 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 AssessmentsSome 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 ReportsEvery 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 SetsClear 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 CalculationsTo 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. |  Liaise with CouncilDuring the design phase we talk to the council and it’s subsidiaries such as ones for transport, stormwater, wastewater to explain to them how the proposal meets their expectations. Although this phase can take some time we manage the process as efficiently as possible to get responses back to the council when they have queries. |  Design Reviews on behalf of CouncilWe 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. |
"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.

COUNCIL LIAISON
Terra Consultants 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 the council has under Section 92 of the Resource Management Act (RMA). We 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.
