Leica Geosystems TruStoryUsing the Leica 3D Disto for planning a lift in an historic building

A lift was to be fitted as part of the renovation of an historic building. The building itself was a three-storey timber-framed construction with vaulted cellar. It was subjected to a total reno-vation, which involved temporary removal and renewal of many of the ceilings and walls. However, the historic timber construction made it impossible to break through all the ceilings at the same time, in order to construct the lift shaft. The renewed floor slab of the ground floor already had the opening for the lift, but the exact position of the hoist itself had to be planned, taking into account a half-timbered wall on the top floor.

No problem for the Leica 3D Disto: The instrument was set up in front of the building in such a manner, that the 4 points of the lift foundation and 2 points of the wall on the top floor could be measured. The result was displayed immediately, which enabled an immediate decision to be reached on site. Subsequently the measu-re-ments were exported as a DXF file. In the architects‘ CAD system the location of the lift could now be fixed to comply with the required distance to the wall. Using the plumbing function, an application from the Disto toolbox, the corners of the lift foundations were easily able to be transferred from a station point outside the building

to all floors. Using the scanning function, the cellar vault, which had to be included in the structural calculations for the location of the lift, was able to be measured. Without the Leica 3D disto, one would have had to have broken through all the ceilings in order to take the measurements using a plumb. Due to the vault and asymmetric geometry, taking the measurements of the cellar using conventional aids (measuring tape, level, laser) would have been extremely complicated.

Result: exact location of wall and foundations in the layout. The lift can now be located accurately to the millimetreMeasuringofwallsandliftfoundations
