In a building or construction project, the client has the overall responsibility for health and safety issues. The developer is responsible for ensuring that the work environment is safe and secure for everyone involved in the project, both before and during the construction process. Together with BAS-P, it is the developer's responsibility to create a work environment plan before the project begins. The plan should include a risk assessment and a description of measures to minimize the risks. By following the work environment plan and taking responsibility for work environment issues, the developer can reduce the risk of accidents and illnesses on the construction site.
