Case Study: technical due diligence for school building portfolio, Hungary, country-wide

1 000 BUILDINGS
150 PROFESSIONALS
3 000 000 M2
7 TB  DATA
8 MONTHS

The client, the Innovative Training Support Center of Hungary needed to survey it’s portfolio of school buildings countrywide in order to see which ones need renovating. A thorough assessment had to be made regarding the state of the buildings, which had 8 different components, of which only one was the LIDAR survey and the resulting floorplans.

The other components included the technical due diligence for each building, comprised of 4 different standardized documents, photo and thermal camera documentation among other things. We had to identify the needs of each institution and the budget for modernizing / renovating it. All the resulting data had to be handed over to the client in a digital database. Due to using the latest technology available in LIDAR scanning, drone mapping, the latest software and also developing our own software, online websites and forms, database, as well as innovating in certain areas of the usual, industry-standard workflows we were able to finish the fieldwork in only 5 months and the whole project in 8. To achieve this we coordinated approximately 25 subcontractors, over 150 professionals

Software & Automation

We developed an online platform to manage the substantial volume of field data received from multiple ground teams. This platform streamlines data access by granting each user permission to view specific data sets. Colleagues in the office can then ensure data quality and completeness using this platform and its integrated database. The next steps involve verifying the data, followed by the creation and completion of standardized documents using a Python script. These documents follow a naming convention and folder structure aligned with the international BIM standard, ISO 19650. This setup allows our client to review and provide feedback on the documents in real-time. Completion of the documents meant among other things, automated processing of the floor area measurements based on the floorplans, categorizing each room into 7 categories, then counting the number of rooms and the total area of each category.

We needed to have this information separately for every building to include it in the written documents. We also had an automated solution in place for sorting, managing the data, correcting folders and file names and to move files easily between our in house and the client’s cloud storage. Ultimately, the data is transferred to a final database that’s delivered upon the project’s completion.

Thermal Imaging

A vital aspect of our work involved analyzing buildings from an energy perspective. This required capturing detailed thermal images of the buildings. Optimal temperatures were essential for these thermal readings, adding a layer of complexity to our project management as our field teams had to time their visits accordingly. Using these images, combined with other field data, we estimated the renovation costs, determined the urgency, and calculated the cost-benefit ratio.
