Long & Cross Sections

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.

We can provide details and plans of the project including the “as constructed” stage of works, i.e. these “as built” surveys are very useful to determine whether the construction tolerances have been met, for instance, lift shaft verticality, the levelling of floors and accuracy of the ‘service holes’ within the site are a few instances that come to mind.

A subset of the layout of buildings, but fundamentally distinct, piles are the stress points of any good design and precise location is crucial and cannot simply be corrected at a later stage. Naturally we take great care with all our work and consider thorough checking of all work and data to be a large part of the finished process. For this we prefer to have access to all electronic data from the architects and consulting engineers to verify that all the information “fits” together before we go to site.

Dependant on the purpose, an elevation survey can show either full detail or outlines for indicative window and door openings for the building. Again the most common plot scale for elevations are 1:100m
