Hille, Thompson & Delfos has expanded and employs Cadastral, Engineering and Mining Surveyors enabling the Practice to diversify. Below is a brief description of our fields of practise.
   
 
   
Cadastral Surveying

Subdivisions, both rural and urban, are guided through the various stages from initial feasibility, rezoning if necessary, design and WAPC application (see our Town Planning Section) to the field survey and lodgement of the registered Plan. This process then allows for the issue of new titles arranged by a Solicitor or Settlement Agent.

Boundary identification or Repegging involves re-surveying in accordance with historical Survey records and we provide an Authorised Surveyor's Certificate and repeg sketch demonstrating any improvements and their relativity to the boundaries.

Strata subdivisions to enable disposal of individual units in duplex or multi-unit development are dealt with under the Strata Titles Act.

Easement surveys are documented to allow reciprocal Grants of Easements for various purposes such as access, water rights and pipelines over other persons land and required to be registered legally on their Title.

Other Land Surveys are carried out on a contract basis for such Authorities as the Dept of Land Administration, Ministry of Housing, Dept of Minerals & Energy and Local Govt. [Top]
Civil Engineering Works
The initial setting out and working control as well as the final "as constructed" plans for roads, earthworks, drains, sewers or other services are familar tasks.[Top]
Structural Engineering & Construction
The Practice continues to be involved in projects requiring the setting out, controlling and checking of buildings, footings, holding down bolts, machinery and complex construction assemblies.[Top]
Topographical Surveys

A variety of Departments and Authorities continue to seek our assistance in the provision of detailed plans to show existing natural or manmade features together with vertical heights and contours.

Architects, Drafters and Builders also request similar detailed plans for project design.[Top]
Pegging of Mineral Claims & Leases

Mineral claims and leases are pegged out, details registered with the respective Mining Registrar for the area, and any necessary Mining Act compliances arranged.

Formal Tenement Surveys for Mining Titles are undertaken for both the Mining Companies and DOME.

Exploration surveys including gridding & Drill Hole setout, Mine Development surveys including Borefield, Mine Infrastructure, Pit layout and Road networks setout are all types of work we have experience in.

Our range of GPS equipment is an efficient tool in most of this type of work.[Top]
High Accuracy GPS

With our range and number of GPS units we are able to undertake various surveys with efficiency and accuracy covering a large area.

GPS is an integral part of our operations nowadays and most if not all of the topics mentioned above and below utilise GPS somewhere.

Hille Thompson & Delfos have recently acquired our 3rd Precise Trimble GPS unit which is available for dry Hire and conveniently located in Perth close to Air or Courier Freight Services.

With our increased Radio Systems we can typically cover the whole of Geraldton (25km Radius) from a GPS Base Station on our Office roof.[Top]
Aerial Photography Control
Establishment of horizontal and vertical survey control stations together with any other survey connections as required for large scale mapping and planning projects. These are usually in conjunction with specialist photogrammetric companies to provide plans and details at pre-determined scales for Mining, Infill Sewer, Defence and major Project design. [Top]
Volume Surveying
We undertake regular measurement and calculations of volumes of stockpiles of various materials to monitor production quantities, stock movement, progress on earthworks etc. [Top]
Database Management of Infrastructure(GIS)

We maintain databases for Clients in graphical form keeping record of infrastructure both above and below ground.

This graphical representation forms the basis for our clients GIS database where they can maintain layered information about maintenance schedules, standards and sizes etc. [Top]
Geodetic or Trigonometrical Control Surveys
Control points are established geographically on a national grid system for mapping purposes, correlation of mining projects and exploratory work. [Top]
