Maintenance and servicing: still in the panel and the software

Two different jobs — they can sit on one contract. Scope, frequency and call-out time in writing. The operating shift can still call if the year-2–3 cover is live.

Scheduled

Servicing

Monthly / quarterly: clean, torque, measure, inspect, consumables. Keep the plant stable; catch drift before a fault.

Year 2–3

Maintenance

Still in the panel and the software: measure, clear faults, support the shift. Call-out time on the contract — not “we will try”.

Typical cover: switchboards, power / ATS / generator, UPS and batteries, HVAC, water and pumps, ELV, controls / BMS, fire-side MEP.

Send the running equipment list, any current schedule, and permitted plant-room hours. Contact.
