Topographical Surveys
Produced at any scale and in most popular digital formats (AutoCAD, Genio, and Microstation). Field data is collected automatically, downloaded and processed to the client's specification. The Topographical survey is often used as the basis for other work such as measured building survey or underground services tracing. Data is generally collected 3 dimensionally and further analysis such as contouring, volumes, sections & visualisations can be produced.
 

 

Deformation Surveys
Almost any structure can
be measured by a variety
of techniques to make comparisons with the design shape, verticality or check for movement over time. Normally angular measurement is used as it generally produces more accurate results than standard EDM.

Underground Services tracing
Normally the procurement of this data is overlaid onto a topographical survey, which has previously been completed. Data for underground services can be collected by a variety of methods from: statutory services search, assumed drainage connections from inspection of drainage chambers, dye tracing of routes, underground tracing or ground probing radar.

Measured Building Surveys
Floor Plans, Elevations and sections are normally produced at scales of 1:50 or 1:100 and in CAD format. Data is collected by a variety of methods depending on the size, shape and accessibility of the building.

Expert Witness Service
Expert advice can be given from a short written report through to court appearances on matters relating to Land Surveying. The company has acted as experts on boundary disputes and professional indemnity claims in the construction industry. Setting Out Normally of large schemes such as pipelines, highways, large construction sites etc, where a primary overall control is required. Setting out is undertaken by EDM but on many larger sites it is becoming more economic to use Real time kinematic GPS.

Modelling / CAD Services
Ranges of software and expert users are available to produce volume calculations, sections, contours, 3D visualisations, isopachyte analysis and digitisation of existing drawings. Software packages used include: Infrasoft, AutoCAD, AutoCAD LT, SCC and Civilcad.
