ASSESSMENT OF LOCAL ENVIRONMENTAL IMPACTS IN CONSTRUCTION PROJECTS USING A KPI-BASED APPROACH

The construction sector is a major global source of environmental pollution, with significant direct and indirect impacts on the environment.Environmental aspects are divided into nine categories, one of which is local issues.Construction causes a multitude of local issues that serve as significant sources of environmental, social, and economic challenges for workers and nearby communities.The insufficient research works and systems for measuring the adverse effects of environmental concerns, both qualitatively and quantitatively, create significant challenges for effective environmental management.To address the challenges, this paper aims to propose a Key Performance Indicators (KPIs)-based approach to assess and analyze local environmental impacts in construction projects by identifying relevant indicators, integrating them into 4D workflows, and enabling data-driven decision-making for sustainable practices.By integrating environmental KPIs with 4D Building Information Modeling (BIM), the model dynamically reflects how each task affects the identified KPIs throughout the project schedule, influencing environment, community well-being, and economic performance over the project lifecycle.The proposed approach provides a holistic understanding of local concerns and facilitates stakeholder collaboration through shared and quantifiable metrics.
