During execution of a construction project, a neighboring business complains that the current building height does not match the initial plans. What should the project manager do first?

The project manager's first step should be to request the neighbor file a formal complaint documenting their concerns. This is crucial for several reasons: it creates an official record of the issue, provides specific details that can be investigated, and ensures the complaint is handled through proper channels. Without a documented complaint, the issue remains an informal conversation, making it difficult to address or escalate effectively. Telling the neighbor the complaint will be escalated to the sponsor is premature without understanding the specifics. Informing the neighbor that documentation has been approved dismisses their concern without investigation. Asking the neighbor to leave is confrontational and does not address the underlying issue.
