Anyone planning a renovation or refurbishment needs a reliable basis that reflects the actual condition of the existing building. But what if up-to-date as-built plans are missing, existing documentation is outdated, or no digital building survey has been carried out yet? Not every project starts with an up-to-date point cloud – and not every project requires a new laser scan. Depending on the documentation already available and how the data will be used, as-built plans and 3

Reliable renovation planning starts with having the most accurate possible understanding of the existing building. However, particularly in older buildings, existing plans are often incomplete, outdated, or no longer reflect the actual as-built conditions. A BIM model based on up-to-date survey data provides a reliable digital foundation for planning and can help identify discrepancies at an early stage and reduce risks in later project phases.

How many buildingSMART-certified tools are there today? 10, 50, or more than 100? Anyone working with BIM quickly encounters a growing number of software solutions, certifications, and standards. In many discussions, the focus shifts away from the actual goal - a consistent and usable model - toward the question of choosing the “right tool.”

When Point Clouds Exist but the Target Model Is Undefined In many projects, a high-quality point cloud is available after surveying, but the question of the “right” next step remains unanswered. Should the data be turned into a BIM model, or are conventional 2D plans sufficient? This is exactly where decisions are often made that later result in unnecessary effort, unsuitable data structures, or models that cannot be used effectively.

The City Hall of Thun is a historic municipal administrative building. To support building operations as well as future planning and development activities, a BIM model at LOD 200 was created for the city administration. The model includes architectural elements, sanitary installations, and the roof structure. Existing structural deviations and deformations were also taken into account.

The Drei Tannen retirement home in Wald, Switzerland, consists of a seven-storey main wing, two two-storey side wings, and two single-storey extensions, all surrounded by extensive green areas. A detailed modeling of the terrain and access roads was therefore an important part of the modeling process, ensuring that the building could be accurately represented and realistically integrated into its surroundings.

The project involves the creation of a comprehensive BIM model and detailed 2D documentation for a care home facility located in Switzerland. The building has a wave-shaped floor plan, composed of two curved wings connected by a central entrance block that houses vertical circulation cores (staircases and elevator halls).

Digitalization is making facility management easier. The focus here is on two key technologies: Building Information Modeling (BIM) and Computer-Aided Facility Management (CAFM). Together, they enable the management of buildings and their operation. In this blog post, we explain how the combination of BIM and CAFM works, how it can improve building operations and the benefits of integrating the system.
