In the context of a construction fee structure, what characterizes a per-diem fee?

A per-diem fee is characterized by a daily charge for time spent on the project. This fee structure is typically used in situations where services are billed based on the amount of time an engineer or professional dedicates to the project on a daily basis, rather than through a flat fee for the entire project or payment tied to specific deliverables or milestones.

This arrangement allows for flexibility, accommodating changes in project scope or duration, and it accurately reflects the true cost of labor as it accumulates daily. Clients value this approach for its clarity in billing time and effort directly associated with the ongoing work.
