    Hospitality projects typically reserve 15–25% for I/O expansion at commissioning. AO/AI are control-critical (PID loop tuning, future setpoint additions) and receive higher reserves. DI/DO are status/command and grow less. Project maturity at proposal stage is early-concept (Construction Bulletin No.8 still being revised), so the upper end of the hospitality range is appropriate.
