Topographical Surveys
Topographical Surveys are used to establish and describe the ‘undulations’ or contours of the ground being surveyed including exact positioning of features on and around the area being mapped. Features such as trees, buildings, pathways, roads, gullies, manholes, utility poles, walls, etc are accurately surveyed. Topographical Surveys are commonly used for; record mapping, boundaries, building positioning, property sale, planning permission and many more. Provision of the above information can be issued in 3 dimensions for input into a BIM system for total management of a building or construction project.
We carry out all topographical surveys in accordance with the standard ‘Topographical Survey Specifications’ as set by The Royal Institution of Chartered Surveyors (RICS), the Land Surveyor and the Architect (LSA) and the Manual of Contract Documents for Highways Works, Volume 5, Section 1, Highway Agency and Department of Transport.
CD Surveys Ltd is a proud member of the TSA (The Survey Association) with our chairman, David Watterston a member of the board of directors.

Volume Calculations
Before any volume calculation can be performed a three dimensional digital terrain model is required. This may be from an actual survey we have completed or from a 3rd party source. The more dense the level coverage is over the area the better as this will produce a more accurate model and therefore volume. Break lines, ie. top and bottoms of banks need to defined and a continual ‘string’ around the extents of the site, mound or spoil heap. It should be noted to the reader that we cannot guarantee these volumes as there is ‘Bulking’ to consider and what happens under the mound, heap or land where the volume will be compared to. This is the assumed gradient from one side to the other of the area, mound or spoil heap in question. Output of any volume will be in cubic metres with ‘Cut or Fill’ noted along with the areas calculated.
Grid Lines
Any Architectural or Engineering design generally involves the establishment of grid lines which are then used by contractors to ‘set-out internal walls, columns, services, external facades etc. Generally grid lines will be set out on site when we are establishing level datums and other works prior to commencement of the construction. Quite often as these lines will go through the columns or piles, these grid lines can be set out with convenient offsets.
Building Monitoring
Building monitoring or any structure which may ‘move’ should be checked for movement. This can be in the form of ‘Tell Tales’ adhered to the fabric, Studs drilled and placed at strategic points to then be accurately levelled or targets adhered to the structure to be used in the monitoring of either or all of the 3 axis. Any movement in these 3 axis, ie. differences in Eastings, Northings and Height would be observed and collected using accurate electronic instruments from robust survey stations away and clear from the site.
