Survey of main post office Doha (Qatar) by use of PointCab

In 1979, the main post office of Doha in the Arab sheikdom Qatar has been designed and constructed by the British architects Twist + Whitley Architects. Beside the counters, the post building houses about 25.000 post office boxes. The building is characterized by many remarkable semi-monocoque roof elements. They bring light into the building and still shadow it well. At temperatures of over 50 degree in summer, this is necessary.

 

Laser scanning for conversion of production facilities

In the course of an extensive project of Intercem Engineering GmbH (www.intercem.de), a leading provider of comprehensive solutions for cement industry, 3D laser scanning technology has been applied to accomplish the survey.

The project was composed of comprehensive tasks: a conversion of an existing filter on a concrete building on the one hand, and the integration of a new cyclone with filter system in the existing concrete structure of a heat exchanger on the other hand.

PointCab for Dimensional Sketches in Accident Documentation

Using 3D technology, traffic accidents can be documented and afterwards reconstructed. For this purpose, the traces and the final positions of the involved vehicles are preserved and documented with all details in a scaled sketch. The dimensional sketch serves for reconstruction of the sequence of events leading to the accidents whereby not only the vehicles’ directions but also the collision and driving speed are determined. Using the results, the injury severity of the occupants can be found out.

Measurement of a Facade via Laser Scanning

Job

For the heritage-protected reconstruction of an ancient industrial building in Magdeburg (Germany), 3D laser scanning has been applied as method of measurement. The survey of three facades of the mentioned building was accomplished via laser scanner and the analysis and interpretation of data by means of the software PointCab and Geograf on a scale of 1:50.

 

Cost-effective survey of towers and complex buildings

Measuring complex building structures as well as buildings which are difficult to access, like the tower in the example, are very demanding with traditional measurement methods.

In addition, difficult conditions for setting scaffolding and a restricted time period for the measurement often occur.

In this case, laser scanning is often a sensible alternative to the traditional survey with tachymeter.

3D Survey of an Historical Industrial Building

3D Survey of an Historical Industrial Building with PointCab and AutoCAD Architecture for Analysis and Interpretation

The in situ scanning was realized without physical contact by a FARO 3d laser scanner within a time frame of about three hours. This approach allowed a thorough visual and geometrical analysis of the scanned areas. Analysis and interpretation were completed in only one day.
