Planning & Documentation (Pre-Commissioning Phase)

• Develop and implement mechanical commissioning plans aligned with ASHRAE guidelines.
• Review design documents, specifications, and IFC drawings while serving as Task Leader (TL).
• Create system verification checklists and detailed functional test procedures.
• Review, update, and enhance mechanical Sequences of Operation (SOO).
• Coordinate with Test and Balance (TAB) contractors to establish complete testing protocols.

Technical Execution (Commissioning Phases 2–6)

Phase 2 – Factory Witness Testing (ASHRAE Level 1)

• Lead factory acceptance tests (FAT) for mechanical, gas, and chemical equipment.
• Document test results and verify compliance with project specifications.

Phase 3 – Construction & Installation Verification (ASHRAE Level 2)

• Conduct visual inspections of gas and chemical installations, structural supports, and field routing.
• Verify compliance with mechanical codes and oversee pressure/hydrostatic and duct leakage testing.
• Confirm equipment access, service clearances, and installation of sensors and control systems.

Phases 4–5 – Operational & Functional Testing (ASHRAE Levels 3–4)

• Coordinate and oversee airflow and hydronic TAB activities.
• Test and verify chemical system controls, including chemical boxes, manifolds, and distribution systems.
• Perform Functional Acceptance Testing (FAT) in alignment with approved SOOs.
• Validate installation of gas systems including piping, tanks, controls, supports/hangers, labeling, and reporting documentation.
• Test and verify Life Safety Systems and ensure proper interaction with gas and chemical equipment.
• Any other duties or responsibilities that may be assigned to you in your role. 

Skills Required:

• 3+ years of experience commissioning gas and chemical equipment in semiconductor or other mission-critical facilities.
