Surveillance cameras have become increasingly significant in the field of construction safety monitoring. With visual information, these cameras support safety managers to identify the potential hazards and deliver prompt feedback. However, developing the surveillance camera plan remains challenging in considering the workspace of working at height activities and the dynamic nature of the construction site. This study proposes a camera installation plan considering different site layouts with time during the optimization to resolve this problem. An approach for Generating Planning for Construction Safety Surveillance Camera Installation in 4D BIM Environment, called SCI4D. The SCI4D comprises three modules: The site profile module (SPM), which extracts the spatial and temporal information from a 4D BIM; Parametric modeling module (PMM), which simulate cameras and calculate the performance of surveillance systems, Installation planning module (IPM) suggests the appropriate solutions that meet the requirement. The efficiency of the SCI4D approach is validated through the test of a building project of 3000 square meters. SCI4D determined 45 solutions with optimal coverage within budget, $2500. The contribution of the proposed approach is to proactively aid project teams in preparing surveillance plan that ultimately supports construction safety monitoring using vision intelligence.
