Topographic Survey

A topographical survey is an accurate collection of spatial features and contours within a particular area and is the foundation of accurate design for a particular development project. We use the collected spatial data to generate highly detailed site plans that illustrate all buildings, paved areas, existing services, ground levels, contours, legal boundaries, trees and drip lines, public services and much more. This detailed information becomes the basis for a subdivision layout or architectural design and is supplied in both paper hard copy and digital DWG format.

Examples of when you may need a topographic survey include: 

- Building design
- Subdivision Design 
- Roading and infrastructure design 
- Stormwater and Flood analysis 
- Landscaping design 
- Slope stability assessments



Are you about to construct a new building, pipeline, driveway or road? Accurately establishing the exact location of a proposed building or structure before being constructed is a sensible and cost effective way to reduce risk of it being built in the wrong location and costing you considerable time and money.

Tripp Andrews can undertake setout surveys efficiently and accurately on any site to give you peace of mind that the construction project is starting in the right place and is in accordance with the relevant design plans. We also offer continuous support and monitoring throughout the construction phase to ensure all elements of the build are on target and in the correct location. We can also produce the relevant setout certifications to satisfy Council building inspectors and engineers. 


As-Built Surveys

An Asbuilt survey is the collection of physical information that shows the exact location and description of structures or defined features after and during construction. Our Asbuilt surveys will capture the exact 3D position and description of the required structure or feature, with plans and the digital information provided to meet your specific requirements. 

Our Registered Professional Surveyors are qualified to certify Engineering works and prepare the appropriate certification and documentation for Council approval.


Building Certification

There is certainly an increasing tendency for building designs to push the limits, and sometimes even beyond the limits allowed for under the relevant Council standards. As a consequence, Councils require a number of certifications by a professionally qualified surveyor as a condition of building consent throughout the duration of most construction projects. These certification checks typically relate to the: 

- Siting (location and extent) of the building / structure 
- Finished Floor Level (We can also set the Finished Floor Level before construction) 
- Height in relation to Boundary and Maximum Height 
- Private Height Restriction Covenants 

Rectifying an issue after the building / structure has been constructed can be very costly, engage Tripp Andrews early in the construction process and be confident you comply with the rules and approved design plans.


Redefinition or Boundary Monumentation Survey

Property boundaries are not always obvious and assumptions often lead to unnecessary and costly disputes between neighbours. While boundary locations may appear obvious onsite due to physical features such as fences and vegetation, the true legal boundary position could be very different. In most instances the physical boundary pegs may have disappeared over time or relocated / disturbed by fencers, the only definitive way to identify the true boundary positions again is to have a Cadastral Surveyor carry out a boundary monumentation or redefinition survey on the site. 

A boundary monumentation survey is supported by a full Cadastral Survey Dataset (CSD) that is submitted to Land Information New Zealand (LINZ) as a record of the peg placement. This ensures that at the time of establishing a new fence, structure or applying to Council for a Resource Consent, the boundaries will be defined legally and will satisfy Council requirements.


Easement / Covenant Surveys

Legal easements allow specific rights over a particular piece of land, usually to benefit neighbouring properties, utility providers and Councils. The extents of these rights are required to be defined by survey before they can be registered on a legal title. Easements are generally created for vehicular or pedestrian access (Right of Way), utility connections and transformers, and for underground pipelines. 

There are many types of land covenants, but generally we deal with protective or restrictive covenants. If you would like to legalise a particular restriction over a certain piece of land or if you have an area of native bush or unique natural habitat that is worth protecting, a restrictive or protective covenant registered on your title is a sensible option. Each case is looked at individually, but generally a site survey is required with a plan generated to illustrate the extent of the restricted area. 

Both Easement and Covenant plans are then legally registered on the subject Certificate of Title at Land Information New Zealand (LINZ) with the assistance of your legal representative.


Rentable Area Survey (BOMA)

In accordance with the PCNZ/PINZ Guide as to the measurement of Rentable Areas, Tripp Andrews can complete an extremely accurate survey of commercial offices, retail and industrial premises to determine the exact rentable areas.


Limited Title Surveys

A certificate of title for a particular piece of land is either described as “guaranteed” or “limited as to parcels”. A guaranteed title is supported by survey definition that is sufficiently accurate and has enough information so that the legal boundaries of the particular land can be determined. Usually, at the time the title was issued, a full survey of the land would have been completed to support the issue of the guaranteed title. 

Titles that are described as “limited as to parcels” are a result of an historical legal requirement. These limitations mean that some or all of your legal boundaries have never been properly defined by survey. At the time that the first title was issued for that land, a guaranteed title could not be issued because either the survey information was insufficient or another party was in adverse possession of part of that title. 
In order to uplift the limitations and obtain a guaranteed title, a full survey of the property boundaries is usually required. To define the boundary location, the surveyor will generally consider any underlying documentary evidence, any long-standing occupation along the boundary and sometimes oral evidence from long standing occupants of the area. The surveyor will use this evidence to determine the position of the legal boundaries and illustrate this information on a new survey plan. This survey plan will need to be approved by Land Information New Zealand (LINZ) before the title is upgraded.  An important step in this process is to give notice or obtain informed consent from all adjoining property owners, this is a legal requirement under the Land Transfer Act 1952. 



Monitoring surveys generally consist of very accurate survey measurements to detect any change or movement of ground / structures during a period of time or construction duration. Tripp Andrews utilise very high precision instruments and methodology that can detect very minor movements or deformation in structures and landforms. Our specialist team can establish monitoring regimes for the full duration of any project, be it short, medium or long term.
