Digital as-built

Measurements and 3D Models from one Source

Refurbishing, renovating or extending existing buildings has many advantages: those buildings are used more efficiently, land consumption and waste of resources are contained and current or future costs are reduced. Lacking basic documents can lead to a complex and long-lasting planning process which even in worst case faces unpleasant surprises.

In order to obtain a reasonable knowledge base about the condition of the building and the room details in the long term, Lindner offers digital as-built documentation with the latest 3D laser scanning technology.

The analogue construction archive goes digital!  In addition to classic surveying, we at Lindner also offer a digital measurement of buildings: Using the latest 3D laser scanning technology, we create a long-term adaptable knowledge base about the conditions of the building and the room details. This helps you to avoid planning errors, loss of time and high costs.

Our 3D scanner measures rooms and buildings simply, quickly and precisely at 360° angles. The resulting point clouds are then modelled and provided for various software tools – as required, in 2D, 3D or BIM-capable. These data serve as the basis for further planning. As a General Planner, we also offer architecture in conjunction with the necessary specialist planning services.

Advantages of Lindner’s digital as-built:

  • Measurements + 3D models from one source, applicable with various softwares (Revit, MicroStation etc.)
  • fast and precise measurements of complex objects 
  • Digitisation of existing building archives and plans
  • Scan-to-BIM: transfer of as-built data into BIM models
  • Simplified documentation (room book, areas according to DIN 277, determination of rental areas, etc. can be adjusted / recorded during the as-built)
  • Error avoidance during restructuring and renovations planning (e.g. collision check possible in advance)
  • Preparation of hazard prevention plans (e.g. points of attack for the fire brigade, escape and rescue routes)
  • Collection of building information (room numbers and designations, door numbers, door classifications, furniture, etc.)
  • reliable project planning at fixed prices (flat rate or according to m² GFA)

As-built Documentation in Transition

An as-built survey is required when the economic efficiency of construction projects needs to be determined, when buildings are renovated and when the specialist planner or architect needs a planning basis, e.g. for a building application or as a requirement from the heritage office. However, both existing buildings and historical buildings, as well as industrial plants or complex geometries, make a subsequent analogue surveying much more difficult – in these cases, using digital measurementtools like a laser scanner is the right choice.

Fast, Simple & Precise

A 3D laser scanner creates well-founded measurements at 360° and is significantly faster than a classic analogue building survey. In addition, the 3D survey saves costs and simplifies processes. Thanks to improved dimensional accuracy, higher information density in the plans and ascertainable masses, the digital measurement reduces the susceptibility to errors in construction and planning. Furthermore, two-dimensional documents such as floor plans, elevations or sections can be easily converted into vivid 3D models or panoramas with the appropriate software. These 3D models not only form the basis for further planning in the BIM standard, but can also be easily integrated into classic workflows: Thus, architects and specialist planners can expect a significant reduction of their workload.

Mobile or Stationary?

The key facts of laser scanning differ from a stationary to a mobile 3D scanner – especially with regard to time expenditure and precision: The mobile scanner scores above all in terms of user-friendliness and speed. It records distances of up to 100 m with an accuracy of 1 cm or more relatively quickly. The stationary scanner, on the other hand, has to be set up at regular intervals and is therefore more time-consuming to use. But the effort is worth it: an accuracy of up to 1 mm can be achieved.

Clear Procedure – Clear Result

However, the way the digital surveying works is similar for a stationary and a handheld 3D room scanner: the 3D scanner first throws an invisible laser beam onto the object to be measured. Then, the laser beams are reflected back and the scanner captures a point cloud. This point cloud can also be expanded with new scans at any time. With the help of suitable software – for example Revit, Microstation, AutoCad or PointCab – the point cloud is further processed into two-dimensional sections or floor plans or into three-dimensional models. Photo documentation is also possible.

Digitalisation offers numerous opportunities for both our company and the entire construction industry: with the help of suitable equipment and software, we integrate digital methods into our workflows and thus offer Add.Vantage (VERLINKUNG) ?? for architects, specialist planners and clients. 3D laser scanner surveying is an important part of this.
