Lead HVAC/mechanical scope end-to-end: design, coordination, site execution, commissioning, and handoverDevelop HVAC design deliverables: load calculations, duct/piping sizing, layouts, schedules, and specificationsReview IFC/client drawings and site conditions; raise RFIs and drive technical resolutions with consultants/clientsPrepare and review shop/coordination drawings and as-builtsPlan and manage on-site implementation: sequencing, daily supervision, quality control, and safety complianceCoordinate HVAC controls and interfaces and ensure system performance requirements are metLead testing & commissioning activities and coordinate integrated commissioning when requiredManage handover documentation: O&M manuals, test reports, warranties, and close-out of snag/punch listsSupport commercial matters for mechanical scope: variations, re-measurements, and technical clarifications

Install, service, and troubleshoot HVAC systems (AHU/FAHU, FCU, split/VRF as applicable)Perform ducting and insulation works; support chilled water/refrigerant piping worksDiagnose faults (airflow, controls, valves, dampers, sensors) and complete rectification efficientlySupport testing & commissioning activities: flushing/pressure tests, balancing support, functional checks, and punch list closureRead drawings and follow method statements; ensure work meets project specs and safety requirementsMaintain daily work reports and coordinate with the site engineer on materials and priorities

For Engineers - site coordination , sales, execution. For Electrical technician - Electrical related site works.
