Site Engineer (Mechanical & Piping)

We seek a competent and safety-focused Mechanical & Piping Site Engineer to ensure the flawless field execution of mechanical and piping systems for a major natural gas project in Singapore. The ideal candidate will have strong technical and supervisory skills, with experience in coordinating complex construction activities in a live plant environment. Experience in planning or supervising lifting operations is a distinct advantage for coordinating critical equipment installation

Bachelor’s Degree in Mechanical Engineering or a related field

Minimum of 5 years of hands-on site engineering experience in mechanical and piping construction within the oil & gas, petrochemical, or related heavy industries.

Proven experience working on natural gas projects (e.g., pipelines, meter stations, terminals, processing facilities) is highly preferred.

Robust understanding of construction sequencing, heavy equipment handling, and interface management.

Practical experience with lifting operations—such as reviewing lift plans, supervising crane operations, or coordinating rigging activities—is a significant advantage.

Possession of a valid Lifting Supervisor Certificate (Singapore MOM-approved) is a strong plus but not mandatory.

Familiarity with Singapore's WSH (Lifting Operations) Regulations and lift planning processes.

Proficient in mechanical/piping codes (ASME, API).

Competent in reading isometric, general arrangement, and P&ID drawings.

Understanding of welding, NDE methods, and pressure testing procedures.

Excellent communication, leadership, and problem-solving skills. Strong interpersonal skills with excellent written and verbal communication abilities

Strong commitment to safety, quality, and environmental standards.

Ability to work independently in a fast-paced and dynamic, multicultural site environment.

Proactive, detail-oriented, and results-driven.

Supervise and inspect the installation, alignment, testing, and pre-commissioning of mechanical equipment (pressure vessels, heat exchangers, pumps, compressors, tanks) and piping systems.

Ensure all work is performed in strict compliance with project specifications, approved drawings (P&IDs, Isometrics, GAs), and relevant codes (ASME B31.3, API, SS).

Review and approve contractor Method Statements, Inspection & Test Plans (ITPs), and work procedures.

Monitor daily work progress, quality, and productivity of contractors. Prepare and submit daily progress reports.

Resolve technical and engineering issues at the site level in coordination with the design office and vendors.

Conduct systematic inspections of materials, fabrication, welding, and installation work.

Witness and sign off on critical tests, including hydrostatic/pneumatic tests, leak tests, and equipment functional tests.

Manage non-conformance reports (NCRs) and ensure timely corrective actions.

Maintain accurate and timely quality records, test packs, and as-built documentation.

Enforce strict adherence to site safety rules, Permit-to-Work (PTW) systems, and Singapore's Workplace Safety and Health (WSH) Act.

Conduct regular safety and workmanship inspections.

Coordinate effectively with other construction disciplines (Civil, Structural, E&I) to ensure seamless workflow and interface management.

Liaise with client representatives, consultants, and equipment vendors.

Utilize your experience to review and provide input on contractors' lift plans and rigging studies for major equipment installation.

Support the site lifting team by offering practical insights during pre-lift meetings for complex mechanical equipment.

Supervise the mechanical aspects of lifts to ensure equipment is correctly prepared, supported, and landed.

Note: Primary responsibility for certified lifting supervision remains with dedicated Lifting Supervisors
