3D Laser Mapping equips Scantech

Scantech International, a specialist 3D laser scanning service company, has selected a state of the art laser scanning system from 3D Laser Mapping. The system is based on a Riegl LMS Z390 scanner and was chosen after extensive field trials that impressed with the speed and accuracy of data capture; the device can capture up to 12,000 measurements per second to 5mm accuracy.

The system was initially used by Scantech to complete a full building survey of Leicester General Hospital in the UK producing as-built drawings, plans and elevation models of every room in the Victorian and more recent buildings. The hospital was originally opened in 1905 to house 512 patients and is now a leading national centre for renal and urology patients and home to the headquarters of the University Hospitals of Leicester NHS Trust. After a competitive tendering process, the project to undertake a full measured building survey was awarded to Scantech International in two parts. Scantech completed the first phase, approximately 10,000 square metres, in 2006 using both traditional survey and laser scanning methods however it was apparent that this method was not ideal for remaining 70,000 square metres.

The second phase of the survey was completed in just 10 weeks and using the measurements captured by the Riegl LMS Z390. Scantech produced plans, elevations and sections of all the rooms in the hospital to allow the hospital’s condition survey consultants and architects to carry out their work using accurate as-built drawings and if required 3D models.

“3D Laser Mapping was able to successfully demonstrate the capabilities of the Riegl LMS Z390,” said Keith McCrory, Managing Director of Scantech International. “The speed of data capture meant that we could minimise disruption to the patients, nursing and medical staff at Leicester General Hospital. A distinct benefit of using the Riegl scanner was that we could complete surveys of each of the surgical theatres in the 90-minute period before operations commenced. This minimised our impact on the day to day workings of the hospital and avoided the problems of out of hours access.”

The Riegl LMS Z390 uses laser beams to record the position of features and surfaces with unrivalled speed, precision and repeatability making it an ideal tool for architectural, archaeological, heritage and engineering projects. The scanner, together with an integrated Nikon D200 12.3MPixel camera for the capture of digital images of the scene being surveyed, can be operated by any standard PC or Notebook and allows wireless data transmission for remote working.
