‘As Built’ Surveys

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.

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.

CD Surveys Ltd will undertake “As Built” Surveys to confirm the positions and levels of boundaries; roads, footpaths, cross-overs, light columns, name plates, pedestrian refuge etc. Once the Survey is drawn in CAD and compared to the design it can then be coloured and offered for adoption and the release of the bonds and insurance which were used for the maintenance of the scheme. Should you require help with any of the above please contact our head office.

Section 38 relates specifically to the creation of new highways upon land in the ownership of anyone other than the highway authority. It is an agreement between the land owner and the authority for the construction of new highway and the ultimate adoption by the authority as a public highway.
The agreement secures a bond for the cost of the works, to enable completion of the works by the authority upon default by the developer, usually for reasons of insolvency but occasionally in instances where the developer has failed to complete the works within a specified or ‘reasonable’ period of time. The agreement also identifies fees payable for supervision by the adopting authority. Any developer or his consultants must enter into a process of submitting detailed design proposals to the authority for approval prior to construction works and sometimes the agreement will not be entered into until the highway authority has been satisfied that all of its criteria can be met.
