construction manager. in Marulan, Australia

Are you a site-focused Construction Manager or Commissioning Lead who excels at pulling together complex brownfield construction packages, managing live-plant interfaces, and driving safe, flawless system startups?

Join a nationally recognised leader in heavy industrial manufacturing and building materials as we deliver a flagship capital transformation program at our major processing facility in the Southern Highlands, NSW.

As part of a multi-million-dollar capital upgrade program focused on plant modernisation and sustainable technology integration, we are seeking a practical, delivery-minded Construction Manager – Site Integration & Commissioning for a 2-year fixed-term contract.

Reporting directly to the Senior Project Manager – Capital Projects, you will take total ownership of late-stage construction completion, multi-package system integration, staged tie-ins, energisation, and operational commissioning. Operating within a contractor-based delivery model, you will bridge the gap between engineering construction and live site operations.

Key Responsibilities

• Site Integration & Commissioning Leadership: Lead site integration and commissioning across Alternative Fuels and Alternative Raw Materials project workstreams, ensuring all equipment, power, and process systems are ready for testing, energisation, and operational handover.
• Shutdown & Tie-In Coordination: Plan, sequence, and manage critical brownfield shutdowns, staged physical tie-ins, energisation routines, system startup, and initial plant ramp-up without disrupting ongoing baseline production.
• Multidisciplinary Interface Management: Drive daily operational alignment across mechanical, electrical, process, and PLC/SCADA control system interfaces, working closely with Package Project Managers, Site Operations, and Engineering teams.
• Punch-Listing & Quality Close-Out: Oversee construction completion, drive punch-list completions, manage defect resolution, and verify all commissioning documentation, procedures, and safety sign-offs ahead of operational turnover.
• Contractor & Site Execution: Manage daily site activities and work sequencing across multiple tier-1 and specialist contractors, resolving site execution conflicts and driving contractor accountability.
• Safety Leadership: Enforce strict compliance with site safety standards, Permit-to-Work (PTW) protocols, isolation procedures, and high-risk activity planning (energisation, hot works, lifting, working at heights) across all contractor teams.

What We Are Looking For

We are seeking a hands-on, proactive construction professional who thrives in fast-paced brownfield environments and possesses the authority and practical problem-solving ability to guide multiple contractors through critical commissioning windows.

• Experience: Minimum 5–10 years’ experience in construction management, commissioning, or capital project delivery within heavy industry, continuous process manufacturing, mining, steel, cement, or heavy industrial infrastructure.
• Brownfield Expertise: Proven track record leading site execution, staged tie-ins, plant shutdowns, energisation, and commissioning in live operating facilities.
• Contractor Management: Demonstrated capability coordinating multiple concurrent trade contractors and specialist equipment vendors across complex physical and operational interfaces.
• Technical Depth: Solid understanding of heavy mechanical handling systems, high/low voltage power distribution, piping/ductwork tie-ins, and PLC/SCADA control system integration.
• Qualifications: A tertiary qualification in Engineering (Mechanical, Electrical, Process, or Civil/Construction) or an equivalent technical/trade background with extensive industrial commissioning leadership experience in Australia is highly regarded.
• Mindset: Exceptional communication, clear decision-making under operational constraints, and an uncompromised commitment to Zero Harm safety leadership.

This is offered as a 2 year fixed term contract. You will join an experienced & knowledgeable leadership group who have sign off to take on two Construction Managers for the captial projects business unit.
