Photogrammetry

Photogrammetry

As part of Listed Building Consent many renovations or refurbishments require documentation of the current use and condition of a building prior to work being carried out. This can be addressed through a photographic record of each room or specified areas that are of cultural and historic significance. As well as the visual recording of the room for prosperity, the images can also act as a record for the condition that a building was in prior to work. This is particularly relevant should features become damaged accidentally during refurbishment or, as a point of reference going forward to identify where damage might be increasing.

High resolution photogrammetry and orthophotography can also be used as an initial starting point for scoping repairs to major projects. Images taken on-site can be scrutinised in further detail from an office location, reducing the costs of site-time labour to document a defect schedule. GBG has recently being involved in several large-scale projects where photography may form the first part in a larger scope of surveying and investigation and enables consultants to target their resources to those areas most in need of intervention.
