Lean and BIM based flight planning for automated data acquisition of bridge structures with LiDAR UAV during construction phase

Abstract: In the execution phase, the acquisition of information is crucial. A key challenge in BIM-based flight plan-ning with unmanned aerial vehicle (UAV) is to de-sign, simulate, verify, possibly optimize and execute the model-based acquisition based on a 4D BIM as IFC. The presented “lean data acquisition process” (LACP) triggers the acquisition event-based and de-mand-oriented (Pull principle) for relevant activities and exclusively acquires the associated components. Then, the LACP comprises model-based planning (Plan), realistic simulation (Do), validation and uni-form evaluation (Check) as well as adjustment (Act). This ensures that only relevant data and information from the construction process are acquired.
