The scope of a project is to replace the street signs within a 10-km radius.

When a client requests a scope change, such as extending the project radius by 1 km, the project manager should first obtain formal acceptance for the work that has been completed within the original scope. Following this, the project manager should submit a change request to address the new requirement. This process is in line with the PMBOK Guide’s Change Management Process, which includes identifying the change, analyzing its impact, documenting it, and presenting it to the Change Control Board (CCB) for approval1.
