Case Study: Drees & Sommer achieves faster, more accurate defect reporting and stronger construction standards compliance with LetsBuild (APROPLAN)

Drees & Sommer Uses APROPLAN to Strengthen Construction Standards Compliance with Tailored Defect Survey Digital Reports

Drees & Sommer, an international consulting and project management firm in the building and real estate sector with 2,400 employees, faced time-consuming manual defect surveys and the challenge of maintaining compliance with multiple regional and national standards. To digitise onsite inspections and speed up reporting they adopted APROPLAN, using its mobile defect-survey and reporting tools to attach photos to plans, export data to Excel, and avoid post‑inspection photo captioning and manual data consolidation.

APROPLAN implemented a structured database of country-specific rules and categorised elements so that when an inspector annotates a point the app immediately flags the applicable standard (for example linking to DIN in Germany), fully digitalising Drees & Sommer’s reporting workflow. The APROPLAN solution produced faster, more accurate inspection reports, eliminated manual exporting and post‑inspection photo referencing, and reduced time spent on defect surveys while improving compliance traceability.
