Job Responsibilities
- Supervise and oversee installation of Bulk Gas (CDA, GN2, LOX, LAr) and Specialty/Toxic Gas distribution systems.
- Supervise high-purity and ultra-high-purity (UHP) stainless steel piping (EP/BA tubing), Gas Cabinets (GC), Valve Manifold Boxes (VMB), gas panels, regulators, and valve manifolds.
- Oversee automatic orbital welding, borescope weld inspections, and weld log documentation.
- Coordinate gas piping routes with process equipment, tool hook-ups, and other MEP services.
- Review gas piping isometrics, P&IDs, layout drawings, specifications, and method statements.
- Coordinate high-pressure pneumatic testing, helium mass spectrometer leak testing, moisture/oxygen analytical testing, and particle counting.
- Monitor purge sequences, nitrogen blanketing, and system pre-commissioning.
- Monitor subcontractor performance, manpower, workmanship, and construction progress.
- Enforce stringent hazardous gas safety standards, Permit-to-Work (PTW) protocols, and project quality requirements.
Requirements
- Diploma or relevant technical qualification in Mechanical, Chemical Engineering, or a related discipline.
- Minimum 3 years of relevant process piping, UHP gas, industrial gas, MEP, or EPC construction experience.
- Certified in MOM-accredited safety courses (e.g., BCSS / SSSC); possession of CSCPM, Confined Space Safety Supervisor, or specialized UHP piping/welding certifications will be an added advantage.
- Fluent in English and Mandarin is preferred to coordinate complex hazardous gas work with international clients and local subcontractors.
- Proven ability to oversee specialty/bulk gas system installation activities on site.
- Strong hands-on knowledge of orbital welding standards, borescope inspection, helium leak testing, and high-pressure safety procedures.
- Experience in semiconductor fabrication plants, gas distribution EPCs, or high-tech cleanroom projects is preferred.
- Able to read and interpret piping isometrics, P&IDs, and hazardous area classification drawings.
