Dynamic Space Conflict Modeling for Construction Operations

Site planning is critical for efficient and safe construction operations. Current industry practice primarily relies on highly experienced planers and their personal judgment to anticipate and prevent space conflicts during construction operation. Inaccurate and unreliable site space planning not only leads to major loss of time and cost, but also negatively impact safety performance. Recent research has introduced new planning methods during the pre-construction phase to enhance site safety and productivity. This paper proposes a site spatial planning solution called Dynamic Space Conflict Modeling (DSCM), which can model dynamic field operations on a construction job site in a 3D model format based on the space demand of each activity and each resource. DSCM provides a process in which schedulers use time, crew information, and space demand of resources as inputs and capture the live space conflict as the output.
