WBS Road Engineering Access Road

The document outlines a Work Breakdown Structure (WBS) for the construction of an access road to a 4-storey classroom block, detailing ten main phases including planning, site preparation, earthworks, and final inspection. Each phase includes specific tasks such as conducting surveys, excavating, constructing pavement, and ensuring quality control. The WBS emphasizes environmental management and compliance with local standards throughout the project.
