The history and development of tall buildings is intrinsically connected with the history and development of lifts for the efficient vertical transportation of people and goods. This is true during the normal operation of a building as well as during building construction. The vertical transportation of resources between floors, such as labor equipment and materials, impacts the overall construction schedule and especially the work of the subcontractors for interior specialty work. This becomes more important and more challenging for taller buildings that are typically served by banks of multiple lifts where construction operations must be scalable to represent spatial repetitions. This paper presents the “LiftSim” multi-floor multi-elevator simulation framework that includes multi-lift control logic, preprocessor replacement, and automatic code generation, that facilitate the development of scalable simulation models in STROBOSCOPE. The “LiftSim” framework can model the floor-to-floor movement of resources and personnel and obtain statistics for different building sizes and designs of operations. The resulting models can analyze and optimize the operation of multiple lifts and hoists (in banks that may not span the entire building height) in very tall buildings. These are illustrated by examples.
