Crux are consulting land surveyors who help clients across various sectors achieve their objectives by providing innovative and professional advice on a range of surveying disciplines


Our consulting surveyors can provide advice on:

  • Subdivision of land

  • Community title

  • Strata title

  • Identification surveys

  • Flood surveys

  • Road and drainage design

  • Topographic surveys

  • Hydrographic surveys

  • Engineering and planning.

We work with clients to solve surveying-related problems facing their projects. Our solutions-based approach involves fully modelling your requirements, and the elements they involve, in order to find the most effective, flexible and cost-effective structure into which they can all be integrated.

Crux is a member of the Association of Consulting Surveyors NSW.

Land and Construction Surveys

Our knowledge of land surveying and construction techniques and methodologies, and the surveying applications required to support them, means we are well equipped to satisfy even the most challenging operational requirements.

Land surveying is encompassed by the broader name of cadastral surveying. Cadastral surveying is the branch of surveying that is concerned with the measurement and definition of property boundaries and the laws of property ownership.

Cadastral surveying requires a comprehensive understanding of land law as well as the technical ability to make accurate measurements. Cadastral surveys can only be undertaken by appropriately registered and licensed surveyors.

Cadastral surveys are undertaken to subdivide land or buildings into parcels for separate ownership under land titles, adjust boundaries between existing parcels and to re-establish the boundaries of existing titles. Cadastral surveying also involves the interpreting and determination of easements and other rights, restrictions and interests in property, and the preparation of survey plans to accurately portray this information.


Our cadastral services include, but are not limited to:

  • Defining your land boundaries

  • Subdivisions and land consolidation

  • Stratum, strata and community plan preparation

  • Lease plans

  • Easement surveys

  • Identification surveys and reports.

Infrastructure Monitoring

Infrastructure. Crux Surveying

Infrastructure monitoring is the surveying technique of logging measured values to the submillimetre and then using the data for deformation analysis. Deformation monitoring systems provide a proactive control of vulnerabilities, related to possible change or failure of a structure.

Crux has expertise in infrastructure monitoring and has adopted several techniques in monitoring deformation of engineering structures.

Engineering structures (such as dams, bridges, viaducts, high-rise buildings, etc.) are subject to deformation due to factors such as changes of ground water levels, tidal phenomena, tectonic phenomena, etc. Monitoring and analysing deformations of these structures constitutes a special branch of surveying which can be grouped into geodetic and non-geodetic techniques. These techniques can also be divided into sub-techniques.

Total station system (TSS)

Surveying with a 0.5" Leica total station system is the most accurate form of deformation monitoring of structures that requires millimetre results. By placing an external control network and adopting a network of baseline measurements, we can provide consistent measurements of the structure to determine the amount and rate of deformation over time.

Global navigation satellite system (GNSS)

A global navigation satellite system offers advantages over conventional terrestrial methods. Intervisibility between stations is not strictly necessary, allowing greater flexibility in the selection of station locations than with terrestrial geodetic surveys. Measurements can be carried out during night or day and under varying weather conditions, which makes GPS measurements economical, especially when multiple receivers can be deployed on the structure during the survey. With recently developed rapid static positioning techniques, the time for the measurements at each station is reduced to a few minutes.

Laser scanning

Existing techniques (e.g., 0.5" total station surveying, GPS) used to monitor large structures such as buildings, viaducts, dams and bridges, while very accurate, are greatly hindered by their low point density. Data acquisition time limits monitoring to only a few samples located at strategic points on the structure. Ground-based laser scanning is a new technology that allows for the rapid, remote measurement of millions of points, thus providing an unprecedented amount of spatial information. This, in turn, permits a more accurate prediction of the forces acting on a structure.

Vertical deformation monitoring can be carried out to the submillimetre using our range of digital levelling techniques.
