Environmental risk assessment for construction sites is a systematic process used to identify, analyze, and control environmental hazards arising from construction activities. It ensures that projects are carried out responsibly while protecting ecosystems, workers, and surrounding communities. The process is often aligned with frameworks developed by organizations such as International Organization for Standardization and regulatory expectations from agencies like Environmental Protection Agency and World Health Organization, which emphasize sustainable and safe industrial practices. The first step is screening and scoping. In this phase, construction planners determine whether a full environmental risk assessment is required and define the boundaries of the study. This includes identifying project activities such as excavation, demolition, material storage, and transportation. The environmental components likely to be affected—such as air, water, soil, vegetation, wildlife, and local communities—are also identified. Clear objectives and assessment criteria are established to guide further analysis. The second step involves baseline environmental data collection. Before construction begins,
