What we do

3D Laser Scanning

3D Laser scanning is a technology used to capture extremely accurate measurements by measuring distances with lasers. The laser scanning instruments are capable of measuring up to a million points a second, combined with powerful processing software to produce highly accurate "point clouds". Some of the benefits and features of 3D laser scanning include:


  • Modern survey accurate laser scanners, including Trimble TX8 HD scanner and Trimble SX10 scanning station
  • TX8 capable of capturing 1,000,000 points per second up to 240m from instrument standpoint
  • Full 360 degree scans in as little as 2 minutes
  • High Dynamic Range photography
  • Delivering industry standard point cloud files (Autodesk ReCap, .e57, .las etc.)
  • Ideal solution for capturing high detail in remote or hazardous environments (Electrical sub-stations, bridges, roads, rail etc.)

Cadastral Surveys

Cadastral Surveys relate to surveys of the land and specifically the location of the boundaries. These surveys are a key part of the framework by which Land Titling in NSW is based. Cadastral surveys are to be undertaken by a Surveyor Registered under the Surveying and Spatial Information Act 2002.

Types of Cadastral surveys include:

  • Subdivision:- Dividing land into smaller parcels of land 
  • Consolidation:- Consolidating multiple parcels into one Lot
  • Acquisition:- Acquiring land for a specific purpose. Acquisitions are carried out by Statutory Authorities.
  • Delimitation:- Confirming deed dimension of Old System parcels being brought under the Real Property Act.
  • Easements Creation:- Creating rights over land in different ownership.
  • Lease Purposes:- Where the lease area is related to the Cadastral boundaries.


These surveys involve the lodgement of a Deposited Plan at Land Registry Services (LRS) prepared by a Registered Surveyor. Upon registration of the Deposited Plan, LRS guarantee the legal boundaries of the subject land. Other forms of Cadastral surveys include:


  • Identification Surveys: - Due diligence survey usually requested for property transactions.
  • Boundary Marking: - Placement of an approved boundary mark to identify the land boundaries.


Cadastral surveys underpin land held under freehold or leasehold title. The majority of land ownership in NSW is held under freehold title and can include land held under Torrens Title, Old System Title, Strata Title and Community Titles. Government Land can be held in name of the individual department or may still be Crown Land.

Engineering Surveys

DS&P has a rich history in providing surveying services within the construction industry. With strict adherence to our Integrated Management System (IMS), quality, reliability and accuracy is assured.


DS&P offer a wide range of support for construction projects from small scale residential to large scale infrastructure projects. The different types of engineering surveys include:


  • Building and high-rise setout
  • Road and civil setout
  • Rail track and turnout setout
  • Volumetric surveys
  • As-built surveys
  • Monitoring surveys
  • 3D laser scanning

With no job being too big or too small, DS&P will meet the needs for all your engineering projects.

Topographical Surveys

Topographic surveys are performed to assist in land development and analysis, whether it be for a design of new subdivision, drainage study, development application for council or a multitude of many other civil related projects.


Typically, a developer or designer will ask for a topographic survey of a parcel of land to show what features, natural or man-made are present. Most topographic surveys generally provide the vertical datum to Australian Height Datum (AHD) and the horizontal datum to either local (site) or state grid such as Map Grid of Australia (MGA).


Topographic survey plans will show details such as reduced levels (RL’s), contours, boundaries, easements, site areas, vegetation features, buildings, utilities (pits, valves, lids, vents etc.) and any other visible improvements on the land. Typically, discussions between the client and surveyor will exactly define the scope and amount of detail required to complete the survey.


DS&P can deliver the survey information in a variety of formats including 2D or 3D AutoCAD (.dwg), PDF, 12d, point cloud data (.rcp, pts, las, e57 formats).

Control Surveys

Control surveys provide the horizontal and vertical positions of points and form the basis of most surveying projects. They provide the standard of accuracy for any subsequent surveys. Control surveys include:


  • GPS / GNSS control surveys
  • Trigonometric
  • Photogrammetric
  • High precision digital levelling


DS&P has a long history of undertaking control surveys for numerous government bodies (TfNSW, Sydney Trains, RMS, Ausgrid) and private organisations. Some types of projects where DS&P has completed control surveys include:


  • Topographic road surveys for Ausgrid to aid in design of new electrical supply routes (surveys > 10km in length)
  • GNSS surveys to establish localised control networks for the design and construction of railway bridges in remote locations throughout the state
  • High precision horizontal & vertical control networks for railway projects, including Sydney Metro and New Intercity Fleet projects
  • Establishment of horizontal & vertical control networks for RMS road projects


DS&P has developed in-house software to compute the field measurements to perform rigorous least squares adjustment calculations using traditional traversing and levelling methods along with GNSS observations. The adjustment calculations are essential to providing accurate and reliable control points.

Data Capture

Data capture surveys are primarily used by Government departments to manage and oversee their assets. Data capture takes the form of Field Data Capture and Asset Data Capture.

Details that form part of a Field Data Capture include:

  • Positioning of buildings and structures within the title boundaries of the property. Playgrounds, access roads and covered ways are included on the overall site plan.
  • Measurement of each room within structures. A room number is assigned to each room.
  • Collection of room data including room use, floor and wall finishes and heating and cooling devices
  • Photos of assets

Field Data Capture surveys have primarily been carried out for the Department of Public Works who manage asset information for the Department of Education (DET). The data provides DET with a data base at all the Primary and High Schools as well as TAFES in NSW allowing the Department to provide appropriate infrastructure for each institution’s needs.

Asset Data Capture is a newer form of data collection which allows the asset owner to forecast future maintenance and budget requirements. Details that form part of an Asset Data Capture include:

  • Roof surface area including downpipes and roof anchor points
  • Building fire systems, emergency lights and smoke detectors
  • Power points, data points, lights and fittings
  • Potable Water tanks, taps drinking fountains and Thermostatic Mixing Valves
  • Heating devices

Asset Data Capture is progressively being introduced into departments overseeing large asset portfolios and will form part of the digital engineering / management of such assets.

Monitoring Surveys

Monitoring surveys provide a precise method of surveying to identify features or structures which may move or possibly move due to human activity such as excavation or underground boring or from natural ground movement and settlement over a period.


Examples of types of monitoring surveys carried out by DS&P include:


  • Road surface monitoring
  • Rail track monitoring
  • Building wall / floor monitoring
  • Settlement monitoring


The benefits of adopting a monitoring solution are:


  • Provides accurate and reliable data
  • Confidence in identifying and applying corrective measures
  • Prevents accidents or unnecessary remedial works through monitoring process


Depending on the site conditions and constraints, a variety of methods may be available to provide the accuracy and cost requirements. Such methods may include high precision digital levelling, conventional total station measurements, 3D laser scanning or 3D metrology techniques. DS&P will be able to provide solid and constructive advice to meet the requirements for any project.


Precise Surveys

Do you have a project that requires submillimetre measurements? Do you need to verify as-built dimensions of structures to high accuracies? If so, DS&P will be able to assist.  Using state of the art 3D Metrology equipment, DS&P in conjunction with their partners can provide solutions to meet your high accuracy needs.
