The research paper is based on a case study of residential buildings where Value Stream Mapping (VSM) is used in the process of construction. It helps in aiding the visualizing and improving process flow to reduce time and enhance efficiency. Through extended site visits, close observations, etc. various forms of waste were identified. Key contributors included insufficient planning, ineffective coordination, and suboptimal methods. Data collection involved on-site monitoring, consultations with engineers, and physical inspections, providing insights into the work schedule and operations. VSM was applied to assess the activity flow of the slab cycle. A Current State Map (CSM) was developed highlighting inefficiencies like material delays and rework primarily arise from conventional methods during the execution phase. A Future State Map (FSM) was proposed by strategically adjusting current processes and identifying value-added and non-value-added activities. Through FSM, site logistics can be enhanced, and the inefficiencies can be significantly reduced. This results in productivity gains by optimizing flow and eliminating waste. The efficacy of the suggestions of the FSM was analyzed by taking the executive’s opinion on the “column casting” activity, and the executives reported potential of significant savings of time and resources by identifying and eliminating non-value-adding activities. By strategically modifying processes and enhancing site logistics, productivity, etc. has markedly increased, achieving up to a 30% improvement. The findings showed immense potential VSM holds in driving transformative results when implemented at construction sites.
