A building set out requires the establishment of key points on site, these are based on the approved building plans provided by the client and the definition of the legal boundaries. If definition issues exist due to age of previous surveys and earthquake movement, then we will let you know before we commence work.

Stamped approved building plans are required to show offsets from boundaries to the building and also height datum for the finished floor height to be set-out. Our surveyors will position two markers along the proposed building wall closest to the boundary, at an offset agreed with you and your builder. We will confirm height datum by placing a nail in a fence post or similar, at the finished floor height shown on the stamped approved plans. We provide the information on the site plan, of the approved stamped plans, with photos.

Please Note:
This price is for a standard residential building set-out (as detailed above) within Christchurch City, Selwyn District or Waimakariri District.

If any additional work is required onsite that will incur possible additional costs, these will be discussed with you to decide on how you wish to proceed. Any additional works agreed to will be invoiced following the conclusion of work.

Dependant on our current workload and commitments, please allow up to 10 working days for the field work to be completed and a further 2 working days for the information to be checked and issued.

If your project falls outside of these guidelines please contact us at hello@do.nz and we are happy to provide a free site specific, no obligation, estimate of costs.

A building location certificate is used by councils, architects and homeowners to confirm the location of the building, prior to construction.

Councils often require the location and or finished floor level (FFL) of a new structure to be determined onsite in relationship to the legal boundaries, to confirm that it is in accordance with the council approved building plans. The certificate is signed off by a Licensed Cadastral Surveyor.

Please Note:
This price is for a standard Building Location Certificate for a residential property within Christchurch City, Selwyn District or Waimakariri District.

Pricing assumes we have completed the topographical survey or the building set-out for the particular project. If not, there may be a need for additional work and costs. These will be discussed with you to decide on how you wish to proceed. Any additional work agreed to will be invoiced following conclusion of works.

We work directly with your builder should you wish – usually 2 – 3 working days’ notice is needed to ensure we can be on site at the appropriate time.

If your project falls outside of these guidelines please contact us at hello@do.nz and are happy to provide a free, no obligation, estimate of costs.

Environmental Science Services

Preliminary Site Investigation (PSI)

The main objectives of a PSI are to gather information about a piece of land to determine whether it may potentially be contaminated, to assess the suitability of the land for its current or intended use, and/or to design a Detailed Site Investigation (DSI), if a DSI is required.

Book a consultation
Read more
Read less

A PSI comprises of
• A desk top study including (but not limited to) a review of Regional Council Land Use Registers (e.g. ECan LLUR) and databases, the District Council property file, available historic aerial photographs and any other existing reports on the site
• A site walkover inspection to identify potential HAIL activities and/or visual indicators of potential soil contamination
• Preparation of a report detailing the investigation methodology and findings

Depending on the proposed activity (for example a subdivision) we will recommend progression to a Detailed Site Investigation prior to completion of the PSI if HAIL activities that may result in a risk to human health are identified.

Please Note:
This price is for a preliminary site investigation on a site of up to 1ha in size within Christchurch City, Selwyn District or Waimakariri District. For larger sites, or sites which fall outside of these areas, please contact us and we will provide a site specific scope and price.

If there are any conditions that need additional work, that will incur possible additional costs, these will be discussed with you to decide on how you wish to proceed. Any additional works agreed to will be invoiced following the conclusion of work.

Detailed Site Investigation (DSI)

A DSI involves intrusive techniques to collect field data and soil samples for analytical testing to determine concentrations of contaminants of concern. A DSI is needed if a PSI indicates a HAIL activity is more likely than not to have occurred and may present a risk.

Book a consultation
Read more
Read less

A DSI is effectively a PSI with the addition of sampling. In addition to the PSI scope of works:
• Collection of soil samples. Depending on the proposed activity or reason for the DSI and results of the desk study (PSI), the samples will be collected on a random, targeted or combined random and targeted basis from the areas of the site identified being potentially affected by identified HAIL activities
• Analysis of samples for identified contaminants of concern typically including heavy metals, asbestos, and at least one of a variety of potential organic compound contaminant groups such as organochlorine pesticides (OCPs) or polycyclic aromatic hydrocarbons (PAHs)
• Preparation of an investigation report that includes comparison of soil analytical data with relevant Soil Contaminant Standards (SCS) and comment on NESCS compliance and soil management requirements.

Notes:
• We own and operate a field X-Ray Fluorescence Analyser (XRF) that enables real time analysis of soil samples for heavy metals in the field. Use of this instrument enables:
o Collection of more data than typical site investigations, resulting in a higher degree of confidence in investigation conclusions
o Real time screening enables onsite preliminary advice regarding likely contamination management requirements.
o Quality control on XRF data is undertaken by laboratory analysis
• The NESCS is soil contamination and human health risk focused, and accordingly DSIs are typically focused on these contamination scenarios. However other contaminant phases may be present (for example groundwater, vapour/landfill gas, surface water) that may present a risk to human health and/or contamination may be present that presents a risk to the environment. We are able to assess and advise on alternative receptors and/or contaminant phases on a site specific basis as and if required.

Please Note:
This price is for a standard DSI on a site of up to 1,000m² in size within Christchurch City, Selwyn District or Waimakariri District. For larger sites, or sites which fall outside of these areas, please contact us and we will provide a site specific scope and price.

The cost is calculated assuming:
• Samples able to be easily collected using manual sampling techniques (hand auger)
• Collection of up to 12 samples from up to 6 locations
• Laboratory analysis of up to 6 samples for heavy metals and 6 samples for PAHs (or up to 4 composite samples for OCPs)
• Additional costs may be incurred if additional analysis or analysis for additional compounds (for example asbestos) is needed.

If there are any conditions that need additional work, that will incur possible additional costs, these will be discussed with you to decide on how you wish to proceed. Any additional works agreed to will be invoiced following the conclusion of work.
