In collaboration with Tektor, ARCh oversaw cadastral reorganisation and technical drawing updates for three WZH hospital sites in The Hague. The main Sammersbrug site covers 16,000 m², ranking among the largest hospital complexes in Europe. Work included floor plan revision, fire escape redesign, and identification of high-risk zones. A second assignment at Bezuidenhout required historical reconstruction from archival documents. A third commission followed at Nieuw Berkendael, a 7,000 m² facility, confirming WZH's trust in our methodology.
