Key Responsibilities

Lead the design development of electrical building services systems, including HV/LV power distribution, substations, transformers, standby generation, switchgear, cable containment/routing, lighting, small power, earthing, and lightning protection.
Prepare and review electrical design calculations, load schedules, single-line diagrams (SLDs), cable sizing, protection coordination/discrimination studies, and voltage drop calculations.
Produce and check design drawings and specifications using AutoCAD/Revit MEP (BIM), ensuring compliance with SS 638 (Code of Practice for Electrical Installations), SS 531, Singapore Standards, BCA, EMA, SCDF, and other relevant statutory and regulatory requirements.
Coordinate with architects, C&S engineers, mechanical/ACMV engineers, and other M&E disciplines to ensure clash-free, buildable, and coordinated designs.
Review and respond to tender and contract drawings, specifications, and Bills of Quantities for electrical scope support tendering and cost estimation as needed.
Liaise with authorities (e.g. SP PowerGrid/EMA, SCDF, BCA) for submissions, approvals, and licensing of electrical installations.
Provide technical support during construction, including reviewing shop drawings, method statements, and material submissions from subcontractors/vendors.
Conduct site inspections, testing, and commissioning oversight to ensure installed works conform to design intent and applicable codes.
Investigate and resolve technical issues arising on site, proposing practical and cost-effective design solutions.
Mentor and guide junior/graduate electrical engineers and draughtsmen, reviewing their output for technical accuracy.
Keep up to date with new technologies, energy-efficient design practices, and evolving regulatory requirements (e.g. Green Mark, sustainability standards).
Support project handover documentation, including as-built drawings, O&M manuals, and testing/commissioning records.
