Prepare a location-and-duty schedule supported by current project records, assignment letters and relevant contracts. Identify the legal entities associated with each site and the employer personnel responsible for supervision.
Explain uncertainty honestly
A realistic anticipated schedule can distinguish confirmed phases from contingencies without pretending every travel date is fixed. Describe the specialised work at each material phase and how it relates to the company’s product or service. Reconcile this map with filing forms and manager descriptions.
If a location is a client site, include the facts needed to assess control and the commercial arrangement. Ask each contracting party for the document naming the responsible manager, not merely the one naming the price. A master services agreement, a purchase order and a site access form often say different things about supervision, and those differences are worth resolving before filing rather than in response to a question.
Mark each phase confirmed, probable or contingent, and say what would settle a contingent one. A schedule presenting every future date as fixed invites scepticism; a schedule that distinguishes them reads as a working document. Where a customer’s security process assigns your employee a site supervisor for safety purposes, record that this role covers site conduct and does not transfer direction of the technical work.
That distinction is easy to state now and awkward to reconstruct later.
