Long & Cross Sections

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.

Detailed Highway Surveys are generally conducted along main roads and streets, require great attention to detail. Along with our normal survey considerations, there are usually issues such as traffic, personnel and the public safety to consider. This especially where large amounts of time are required in the road, due to extra detail required such as; road markings, lane delineation and central reservation information. Roads are normally surveyed to extents of highway boundary, although clients sometimes require, with permission from property owners, to give them information on adjoining building, positions of trees and other relevant detail when planning, large ‘above road’ structures.

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.

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.
