Commencement orders and schedule letters: wording aligned with contract procedure

Point to the contract’s commencement conditions, state facts showing what is satisfied or not, and give planned start date and site representatives.

If preconditions are disputed, separate “planned start” from “actual readiness to start” and propose engineer/owner coordination rather than unilateral calls.

For schedule-network-related mail, briefly note whether critical-path activities are impacted to support later delay analysis.
