Start with the work that stops
List the items that can halt a job: moisture-control equipment, personal protective equipment, fuel, disposal service, specialty cleaning products, laboratory testing or a trade contractor. For each, record the normal supplier, the last workable substitute, ordering cutoffs and any qualification or compatibility limits. The Ready Business program recommends planning for disruptions that can affect facilities, staff, suppliers and operations. Its guidance is a planning framework, not a guarantee that a backup will be available. Then identify the decision owner. A field supervisor may recognize the shortage, while an estimator, project manager or owner must approve a substitution that changes cost, scope or a customer commitment. Define the handoff and the authority level in advance. This prevents a familiar emergency pattern: several people call suppliers, no one records the result and the customer receives conflicting timing updates.Test the list in ordinary work
Use routine purchasing to test phone numbers, account status, delivery zones and lead times. Ask whether a substitute item requires different training, power, fittings or documentation. A lower-priced item is not automatically equivalent. Preserve the manufacturer instructions and job-specific safety requirements; a continuity list should not authorize unsafe use or bypass contract terms. For a hypothetical water-loss project, the list might show that the primary equipment supplier is closed on Sunday, a second supplier can deliver only within 40 miles, and a rental requires a manager’s approval. That information changes the promise made to the customer before a crew is dispatched. Review the list after a real delay. Add the failure point, the response that worked and a named owner for the correction. NDR’s Business archive covers related operations decisions. A small, current continuity list can protect both the schedule and the credibility of the update given to the customer.Keep the list short enough to use under pressure. A one-page table can include the material or service, normal source, confirmed alternate, after-hours contact, delivery area, expected decision owner and a note about any technical limitation. Store it where dispatch, estimating and field leadership can reach the current version. A spreadsheet that only one person can open is not a continuity tool during an interruption.
Communicate the substitution decision to the customer in plain terms. State what is changing, what remains uncertain and when the next update will arrive. Do not claim that an alternate source will meet the original schedule until its delivery and suitability are confirmed. This is a practical operating discipline, not a promise against all supply-chain disruption.
Make one person responsible for reviewing this record after each major job and recording what changed.
