Hand drawings from 1915 became a BIM model

Digitising 2D material to BIM is a large – but necessary – task when beginning renovation projects or other types of projects linked to existing buildings. It is particularly important today, where energy renovation is becoming more and more relevant, to ensure that the digital foundation is correct.

Having a BIM project delivered that has been created on the basis of the 2D material that is available at the beginning of the project saves time and resources. The starting point can be from 2D DWG-drawings, but in the case of old buildings, the only existing drawing material is mostly hand drawings of fluctuating quality. But even these scanned hand drawings can actually become high quality models.

Digitisation as a service
BIM Equity offers digitisation as a service. We have for example provided an extremely detailed model of the former police station on Kildegårdsvej in Hellerup. Architect H.C. Rørdam has used the BIM model for sketching and designing the renovation of the building.

Work on the digitisation was based on scanned hand drawings from 1915, scanned hand drawings from the initial renovation in 1983 (which only contained the redeveloped elements), and photos taken of all the changes made since 1983. It was necessary to structure the drawing material before the modelling work began.

Development of the BIM model
BIM Equity produced the BIM model with the help of the Aidea design studio in the Philippines, which has extensive experience of BIM. The company has around 175 employees, the vast majority of them architects with advanced BIM competencies, which makes them ideal for digitising tasks of this size.

BIM models of existing buildings mean that the architect can immediately begin the design process, rather than spending time and resources on structuring the 2D material and modelling a complex 3D model – a process that often takes several weeks.
