Construction and Engineering Surveyors

At Crossland and Hardy our engineering surveyors are certified by the Surveying and Spatial Sciences Institute’s Engineering and Mining Surveying Commission (Australasia Pacific). This is an internationally recognised certification and endorsement means that our professionalism, skills and expertise are recognised as being of the highest level.

The team at Crossland and Hardy have a wealth of experience in providing surveying solutions for large and small construction and engineering projects.

The examples below describe the most common types of surveys that we provide, but is not exhaustive. We can customise a solution to suit you, please contact us to discuss your needs.

Road & Rail Construction

Road and Rail Construction

Our team has been involved in a wide variety of road and construction projects and can assist with all aspects of the construction process including:

  • initial control and topographic surveys of the corridor prior to construction. These surveys are necessary for the planning phase of the project
  • corridor boundary establishment
  • bulk earthworks set-out for embankments, cuttings and formation
  • set-out and as-constructed surveys of final grade for roads, or rail alignment and level in the case of rail construction projects
  • Computation of volumes and quantities; e.g. for progress payments
  • Audit (compliance) surveys

Underground Services

Underground Services

Whether you are involved in a major development or simply subdividing a residential block there will be a need for new underground services such as sewer, communications, drainage, electricity and gas.

In many cases it is sufficient to simply undertake a boundary survey (either a re-establishment or a new boundary survey). The new services can then be installed relative to the boundary marks. For larger projects dedicated services set-out surveys are usually required such as may be required for large scale subdivisions or redevelopments.

Utility agencies will require an as-constructed survey. This is performed immediately after installation, before back-filling of the excavation. From the survey results we then draft an as-constructed drawing or summary to conform to the standards of the relevant utility.

As-Constructed Surveys

Routinely, developers and contractors are obliged to provide as-constructed surveys, sometimes called as-built surveys, of any new works or infrastructure as part of the conditions for approval (or payment) of the project or development.

During an as-constructed survey, the surveyor will physically measure all of the critical aspects of the new work. For example the surface of a new road will be subject to design
tolerances in alignment, grade and level. The surveyor will measure sufficient
points at a distribution necessary to enable comparison of the as-constructed road
against design dimensions. For a sewer as-constructed survey the gradients and
invert levels of the new pipework will be measured as well as the position in relation
to an alignment such as the cadastral boundary.

Bulk Earthworks and Volume Surveys

This type of survey is usually associated with larger projects such as roads and railways, large scale subdivisions, dams and other large developments such as pads for industrial infrastructure.

Crossland and Hardy utilise the latest precision robotic total station equipment and GPS instruments in order to maximise productivity in the field. We have a seamless office-to-field workflow that means we can be out in the field sooner. Should new data arrive or if the design is changed this technology also allows us to remotely update the instrument database so that the surveyor does not need to return to the office.

As well as set-out of earthworks, a major component of this type of project is volumetric computations. From field survey results we can quickly compute volumes for design or progress purposes using modern desktop software.

Concrete and Holding Down Bolts Surveys

Crossland and Hardy use high precision digital equipment to accurately survey industrial and civil concrete works. Our surveyors have set out numerous pedestals, slabs, columns, bolt patterns and footings on a variety of large and small projects.

We also provide pre-pour verification surveys (audit surveys) on critical components such as holding down bolts.

For small scale building developments we can provide a grid-line set out survey at relatively low cost.

Monitoring and Deformation Surveys

Where there is risk or suspicion that disturbance to the ground is causing movement or deformation to existing structures or infrastructure, a monitoring survey is undertaken to quantify the magnitude and direction of the movements. The disturbance may be caused by natural processes such as fluctuating ground water levels or may be as a result of man-made influences such as new construction works in the vicinity.

The monitoring survey is an on-going process whereby regular measurements to the same points are made and compared to the first (baseline) measurements. Very small changes in position (millimetres) can be detected and when analysed over a period of time can be used to predict possible future disturbance, making this type of survey a valuable early-warning tool.
