Deformation survey and monitoring

To analyse and illustrate the deformation of buildings three-dimensional measuring data is used to calculate surface models. The required data is collected by photogrammetric evaluation of stereo images, totalstation measurements or with a laser scanner. Using these digital surface models, sections and heights are construed.

The continuous vertical movement of buildings is monitored at intervals. For that purpose precision levelling is performed using durably marked control points with digital levels and DNA levelling staffs. Inclinations and deformations are determined by a totalstation survey of control points and monitored. These metric surveys are repeated over several years and their results are presented in a suitable form as tables or graphics.

metric survey during the construction period  

Large building projects at historic monuments are attended by complex metric surveys. Beyond the deformation-true totalstation survey as a basis for planning the changes in the building (documentation prior to demolition, monitoring measurement) are documented and specialised surveying during the construction phases can take place (stake-out, levelling and control measurements).

In addition to metric surveys of buildings, site plans and contour maps as well as tree population plans can be provided for a complex planning of reconstruction and conservation measures, disposal and supply plans and last but not least landscape planning.

Metric surveys of buildings by totalstation   (Brochure: 1,747 kB)
Metric surveys of buildings by totalstation

The metric building survey is achieved predominantly with a reflectorless electronic totalstation in a uniform coordinate system. A software interface specifically developed for coded totalstation survey of buildings ensures the combination of photogrammetry and metric building survey with a high level of detail.
Profile heights and axis can be marked in the building by meter markers, so that additional measuring by hand is possible. The measurements of all floor plans, cross and longitudinal sections, developed surfaces of walls, elevation drawings of facades etc. are evaluated in a CAD system.
