Building Elevations

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.

Provision of long and cross sections from, for instance ditch or river surveys can be provided preferably from a digital terrain model (DTM) of the site. This information could then be used for calculations of flows and volumes in a hydraulic model.

Any land (or elevations) with contours depict the ‘undulations’ on the surface of the site or area in question and these are normally shown at quarter or half metre intervals related to the site or Ordnance Survey Grid System and height datum. On elevations these can show irregularities with the contours depicted at 5 − 10mm and could show ‘sags or bulges’ in the façade or structure. Data supplied by CD Surveys or by a third party can be processed, then presented as a fully edited three dimensional Digital Terrain Model (DTM) for the use in Engineering Design on Micro station MX (MOSS) or the PDS design systems.
