Section 38/109 Drawings

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.

Verticality Measurements

The ‘plumbness’ of structures is very important especially when lift shafts have been installed or changed. This also applies to a new build between flank walls on another property. CD Surveys Ltd can provide verticality measurements prior to the build and will establish whether remedies are required to avoid the clash with adjoining buildings in relation to the proposed construction.

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.

DJI Aerial Drone Survey Systems

Our aerial surveying capabilities have been expanded with two professional, survey-grade DJI platforms: the DJI Matrice 4E and the DJI M300 RTK. These state-of-the-art systems enable rapid collection of highly accurate aerial data, making them well suited for construction, land development, and infrastructure projects.

Aerial imaging offers a safe, precise, and efficient way to capture detailed site information from above. Drone surveys significantly reduce time spent on-site and allow access to hazardous or hard-to-reach areas without risk. The resulting high-quality datasets integrate seamlessly with ground surveys and CAD deliverables, providing reliable and efficient project outcomes.
