Verticality Measurements

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.

Topographical Surveys are used to establish and describe the ‘undulations’ or contours of the ground being surveyed including exact positioning of features on and around the area being mapped. Features such as trees, buildings, pathways, roads, gullies, manholes, utility poles, walls, etc are accurately surveyed. Topographical Surveys are commonly used for; record mapping, boundaries, building positioning, property sale, planning permission and many more. 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.

We carry out all topographical surveys in accordance with the standard ‘Topographical Survey Specifications’ as set by The Royal Institution of Chartered Surveyors (RICS), the Land Surveyor and the Architect (LSA) and the Manual of Contract Documents for Highways Works, Volume 5, Section 1, Highway Agency and Department of Transport.

Once the ‘building’ survey has been completed with elevations and floor plans the ‘section’ lines are selected (if not established from the client, Architect or Engineer) and a ‘Cross Section’ is formed from this information. However now that we are ‘Laser Scanning’ more and more buildings and sites the supply of cross sections are more concise.
