PDA Surveyors has been the leader in the Tasmanian surveying industry since the firm was established in 1953. We are experts in all aspects of land and engineering surveying and offer exceptional service utilising start-of-the-art surveying technology. Our experienced team are highly innovative and are ready to deliver on your next project no matter how large or small.

Cadastral Surveys

PDA Surveyors employs a number of Registered Land Surveyors with many years of experience and a wealth of knowledge in the profession. Cadastral surveys involve title boundary re-establishment and can include:

  • Boundary Identification Surveys
  • Boundary Remark Surveys
  • Subdivision – Urban and Rural
  • Easement Surveys
  • Strata Surveys
  • Lease Surveys
  • Gross and Net Lettable Area Surveys
  • Surveys to support applications for Tile by possession
  • Surveys of Crown Land
  • Acquisition Surveys

We can often offer a number of different solutions depending on your requirements. If you are purchasing a new home or are re-fencing and want peace of mind and assurance of knowing where your boundaries are, or you are interested in undertaking a subdivision or strata development, contact your nearest PDA Surveyors office to discuss the options available.

Engineering/Construction Surveys

PDA Surveyors will provide the right solution for all your engineering, planning or construction requirements. Whether it is a survey for conceptual design, detailed design, construction set out or as-built surveys, we can tailor a solution to meet the needs of your project. PDA Surveyors can provide:

  • Contour and Detail Surveys
  • Construction Set Out Surveys
  • Road, Rail or Pipeline Corridor Surveys
  • 3D Built Environment (Building / Plant) Surveys
  • Digital Terrain Modelling
  • Piling Surveys
  • Dam site surveys and volumes
  • Data modelling and management
  • Machine control
  • Site positioning management

Monitoring and Alignment Surveys

PDA Surveyors can provide spatial solutions for your monitoring and mechanical alignment requirements on both small and large projects. We have extensive experience in providing building and structural deformation monitoring, land slip monitoring, alignment surveys for mechanical plant refurbishment and retro fitting of new equipment to existing plant. PDA Surveyors has specialised equipment for undertaking monitoring and alignment surveys including high-precision total station theodolites, precise and digital levels, and the very latest in laser scanning technology.

Hydrographic Surveys

PDA Surveyors have extensive experience undertaking hydrographic surveys of bathymetry for a range of applications throughout Tasmania. These include combined terrestrial and bathymetric surveys, surveys of the sea floor for the design of marine structures, aquaculture applications and engineering design, and river profile surveys for flood modelling and for the design of submarine pipelines and cables. PDA Surveyors also undertake surveys of dams to calculate water storage volumes and we also provide services in dam design.

A major benefit of the hydrographic survey systems utilised by our surveyors is that terrestrial survey data can be linked seamlessly with bathymetric data to deliver a single homogeneous model. This is achieved by integrating real-time kinematic GNSS with depth sounder technology that can be mounted on virtually any vessel from a small inflatable to an ocean-going workboat. We also operate a remotely controlled/autonomous USV (Unmanned Survey Vessel) allowing our team to undertake various hydrographic surveys from the safety of the shore. This system is of particular advantage for surveying sensitive impoundments such as reservoirs and mine tailings dams, or bodies of water where access by boat is deemed unsafe or undesirable.

Mining Operation Surveys

PDA Surveyors provide specialist surveying services to a number of mines on the West Coast of Tasmania. Services provided include routine surveys of stockpile volumes and working faces as well as project specific surveys. We also work with staff mine surveyors to provide increased capacity or additional skills that are required for a particular project.

These may include engineering detail and set out surveys for mine expansion or upgrades, monitoring surveys of control or deformation networks, survey support for seismic exploration, pipeline and plant surveys including laser scanning of plant and all types of mining lease and tenure surveys.

Pipeline Surveys

PDA Surveyors have extensive experience in pipeline route alignment surveys and construction set out surveys with over 5,000km of pipelines surveyed by our staff throughout Tasmania and interstate. We can provide experienced surveyors to complete all of the survey requirements of your project. Services provided include initial corridor/route alignment surveys, detail surveys for alignment sheets, hydrostatic profile and engineering design, construction set out surveys and as-built surveys.
