Key Responsibilities

 1. Design & Technical Oversight

  • Integrated Building Services: Manage the end-to-end mechanical design process during tender and delivery, focusing on HVAC/Mechanical Ventilation, Fire Suppression/Detection systems, and Hydraulic (Plumbing, Drainage & Sewage, Rainwater Water Harvesting) System.
  • Metro & Infrastructure Expertise: Lead the design coordination for specialized environments, including tunnel ventilation, station cooling, and fire safety systems for Metro/Rail projects.
  • Technical Review: Review tender and delivery design documents, drawings, calculations (e.g., heat load, hydraulic pressure drops, smoke modeling), and reports produced by consultants for technical compliance, constructability, and cost efficiency.
  • Value Engineering: Lead value engineering exercises to optimize equipment selection (chillers, pumps, fans), simplify installation methodologies, and identify alternative technical solutions that balance CAPEX/OPEX without compromising safety or performance.
  • Interdisciplinary Coordination: Coordinate and interface with Architects, Electrical, Civil, and Structural teams to ensure BIM integration and resolve spatial clashes in complex plant rooms and service corridors.
  • Lifecycle Awareness: Propose design solutions that are cost-conscious regarding construction, Testing & Commissioning (T&C), and long-term Facilities Management (FM).
  • Continuous Improvement: Conduct post-tender and post-completion design reviews to capture lessons learned and improve future delivery benchmarks.

2. Consultant & Stakeholder Management

  • Consultant Oversight: Manage and coordinate with external design consultants during all project phases, ensuring alignment with Gamuda’s project objectives and international standards.
  • Contractual Management: Develop and manage consultant Scopes of Work (SoW), deliverable schedules, and performance metrics.
  • Conflict Resolution: Lead design coordination meetings to resolve interdisciplinary technical clashes and ensure seamless system integration.
  • Tender Support: Support tender submission activities, including Fire Engineering/HAZOP studies, risk assessments, and the preparation of Bills of Quantities (BOQ).

3. Team & Leadership

  • Mentorship: Provide technical guidance and mentorship to junior mechanical engineers, fostering a culture of technical excellence.
  • Innovation: Stay updated on emerging technologies in building services, such as District Cooling Systems (DCS), smart building automation, sustainable/green building technologies (LEED/GBI) and IoT-enabled solution.

Qualifications

  • Bachelor’s Degree in Mechanical Engineering or equivalent.
  • Competency in AutoCAD, Revit (BIM), and mechanical modeling software (e.g., Carrier HAP, Bluebeam).
  • Strong technical writing skills and the ability to communicate complex engineering concepts to non-technical stakeholders

Skills & Abilities

  • Proven track record in Metro or Underground Rail infrastructure projects, or comparable large -scale infrastructure large scale development.
  • Familiarity with Australian Standards (AS/NZS) or international building codes relevant to the ANZ region.
  • Experience in complex high pressure hydraulic systems for high-rise or infrastructure assets.
  • Knowledge of smart HVAC controls, Building Management Systems (BMS) and/or Energy Management Systems (EMS).
  • Experience with tunnel ventilation system for rail or road tunnel.

Expected Minimum Years of Experience

  • Minimum of 8-10 years of experience in building services design or construction.
