Grid Lines

Floor or DPC level surveys related to GPS or Ordnance Survey Bench information can then be used to determine whether a building or area of land is liable to flooding. Our information is generally then issued to the Environmental Agency or a specialist company who will then provide a concise report for any Floor Risk Assessment.

Whether we are asked to peg out highway boundaries or setting out a centre line with offsets, our Engineers and office based staff work together to ensure that you get your design placed where it was intended, and more importantly to the required accuracy. Setting out foundations, block or brickwork, pinning out preliminary designs, positioning roof or steel structures, providing level datums at all stages of construction, we can do it all.

The co-ordination and location of permanent markers to withstand the rigours of site operations are also required and we can provide relocatable points of reference to either Ordnance Survey control or arbitrary grid data. We perform topographical surveys before or after site work, to ascertain quantity of land removed or working along side ground workers to define levels for foundation or final profiles. Relocating existing property boundaries from title deeds or registry plans, or assisting in the definition of new or disputed ones, we are frequently called on to establish/confirm fence lines or wall positions.

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.

Proposed construction needs to be in the right place and at the right height. You will need our professional team to provide services such as site setting out of grids, datums, piles, etc. Volumes and verticality surveys can also be provided.
