milestones. • Take overall responsibility for the mechanical commissioning strategy and execution., • Lead and coordinate Mechanical Commissioning Engineers, subcontractors, vendors and specialist commissioning providers., • Develop and maintain the mechanical commissioning programme aligned with the overall project master programme., • Drive mechanical systems through the agreed Level 1–5 commissioning process, where applicable to the project., • Ensure commissioning activities are planned, sequenced and executed safely and efficiently., • Establish clear system and area priorities based on energisation, cooling availability and IST requirements., • Lead daily and weekly commissioning coordination meetings., • Provide clear reporting on progress, constraints, risks and recovery actions., • Chilled water systems, • CRAHs / CRACs, • AHUs and ventilation systems, • Pumps and pump skids, • Pressurisation and expansion systems, • Heat exchangers, • Dry coolers / heat rejection equipment, • Mechanical plant rooms, • Control valves and actuators, • Flow, pressure and temperature instrumentation, • Leak detection interfaces, • Water treatment systems, • Drainage systems, • BMS-controlled mechanical equipment, • Packaged mechanical plant and associated controls, • Work closely with the Mechanical Construction Manager to establish a structured transition from construction completion to commissioning., • Define and manage mechanical completion requirements at system and subsystem level., • Ensure installations are inspected and sufficiently complete before commissioning activities commence., • Review outstanding construction snags and identify items that prevent or impact commissioning., • Drive completion of commissioning‑critical snags., • Ensure equipment is correctly installed, labelled, accessible and ready for testing., • Confirm all required utilities, permanent power, controls and communications are available before testing., • Pipework flushing and cleaning, • Pressure testing, • Chemical cleaning and treatment, • Filling and dosing, • Water quality verification, • System venting, • Pump alignment and rotation checks, • Strainer inspections, • Valve position verification, • Equipment start‐up checks, • Sensor and instrumentation verification, • TAB / air and water balancing, • Flow verification, • Equipment vendor start‑up Ensure all
