• Performed electrical, instrumentation, and pneumatic engineering studies including material take-off,
manhour estimation, design calculations, and preparation of DERF, CWO, and engineering deliverables.
• Designed and developed MV/LV and instrumentation systems based on P&ID, including electrical
drawings, simulations, and integration with PLC-SCADA systems.
• Supported procurement and construction activities by preparing PRF, reviewing vendor quotations,
coordinating multidisciplinary teams, and supervising detailing works.
• Supported site execution including SAT, pre-commissioning, commissioning, safety toolbox meetings,
progress reporting, and coordination with vendors and subcontractors.

• Supervised subcontractor activities for electrical installation works including cable tray, grounding,
switchgear, transformers, panels, duct banks, lighting, and cabling in accordance with approved
drawings.
• Coordinated with multidisciplinary teams and vendors to resolve site deviations through RFI and FCN
processes, ensuring compliance with Basic Engineering Design and Electrical Design Criteria.
• Ensured HSE compliance by enforcing PTW, JSEA, toolbox meetings, inspections, and monitoring
quality through IPMT inspections, NCR, and PMAR closure.
• Monitored installation progress, verified typical installation details, supported SAT and commissioning
activities, and prepared daily, weekly, and monthly progress reports.

• Designed electrical and instrumentation drawings for control panels and field installations, reviewed
P&ID and GA drawings, and ensured compliance with applicable electrical standards prior to
manufacturing and assembly.
• Coordinated with clients on electrical, instrumentation, PLC, and software requirements; prepared
BOM, performed technical and cost evaluations, selected instruments, sensors, and pneumatic
components, and confirmed control and assembly design.
• Verified PLC logic, I/O configuration, and VFD parameters; maintained AutoCAD Electrical databases
including schematics, panel layouts, cable schedules, terminal mappings, and system architecture.
• Supervised panel assembly and testing, supported sensor calibration, electrical safety tests, FAT,
commissioning, and site installation, including management of design changes through PCN and UL
inspection compliance.
