Site preparation for a construction project involves getting the site and surrounding areas ready for construction activities. This includes cleaning up the site, ensuring it looks presentable to neighbors and passersby, managing water runoff to prevent issues, and determining the placement of facilities like portable toilets. It is important to consider the impact of construction on neighbors, traffic, and the environment to ensure a smooth and successful project.
