Measured surveys

Measured surveys

Measured surveys involve taking measurements of sites or buildings in order to produce accurate data that is then represented at a reduced scale. They are usually specified to an agreed level of detail, to acceptable accuracy tolerances, scale, delivery times and costs.

An initial collection of accurate site data will provide the 'building block' of core information on which all subsequent phases of planning, design and development are based. This was recognised in 2011 by the government initiative for building information modelling (BIM) whereby 3D spatial information about a building is tagged with feature intelligence and then shared between users throughout the building’s lifetime, design through to demolition.

The systematic measurement processes involved in measured surveys in recent times will include the use of sophisticated survey equipment, but that situation may not necessarily infer accuracy. Irrespective of the methods of data capture, once dimensional data is published, there is some risk that it will be regarded by all potential data users as being complete and accurate and entirely ‘fit-for-purpose’. This is most likely to be the case through the use of appropriate professional services.
