Role purpose

The Commissioning Operations Manager is responsible for the effective management, coordination and utilisation of commissioning resources across multiple projects. The role ensures that commissioning personnel and specialist subcontractors are deployed efficiently in line with project programmes and operational priorities, whilst maintaining high standards of safety, quality and productivity.

The post holder will oversee workforce planning, manage the approval of timesheets, analyse and report on resource utilisation, and manage subcontractor programmes, deliverables, timesheets and invoices. The role also supports project delivery through the coordination of site personnel, logistics and equipment. Technical commissioning decisions remain with qualified Commissioning Engineers, who provide technical support to the role.

Responsibilities & Duties

Resource Management

• Lead and manage the allocation of Commissioning Department personnel across all projects, in line with project programmes and business priorities.
• Maintain the department resource plan, covering live projects, confirmed work and the tender pipeline.
• Monitor future staffing requirements and identify skill shortages or capacity gaps early enough to address them through recruitment, contract labour or re-sequencing of work.
• Support recruitment, onboarding, resource planning, training coordination and operational performance management of commissioning personnel. Technical competency assessment remains the responsibility of Head of Commissioning.
• Maintain competency records and confirm that personnel hold valid qualifications, training, authorisations and site access before deployment.
• Arrange the mobilisation and demobilisation of personnel, including travel, accommodation, vehicles and equipment.

Workforce Planning and Time Management

• Plan and monitor employees’ working hours, rotas and shift patterns to make efficient use of available resource.
• Manage holiday requests and absence records so that availability is accurately reflected in the resource plan.
• Manage the weekly timesheet process for the department, ensuring timesheets are submitted by the agreed deadline.
• Review and approve timesheets against the resource plan, site attendance records and the correct project and activity codes, resolving any discrepancies with the individual.

Time Utilisation Analysis and Reporting

• Collect and analyse approved time data to measure the utilisation of commissioning personnel.
• Monitor productive and non-productive hours, travel time and standby, and identify opportunities to improve resource utilisation.
• Compare actual deployment against the resource plan to measure and improve forecast accuracy.
• Produce regular management reports on resource utilisation, availability, deployment efficiency and workforce planning metrics.
• Develop and maintain the tools and processes used for time recording and reporting, improving the quality and accuracy of data.

Subcontractor Management

• Support Head of Commissioning to agree the scope, named personnel, programme and deliverables with specialist subcontractors before mobilisation, and include their resources in the department resource plan.
• Monitor subcontractor progress against agreed programmes and milestones, escalating any slippage to the relevant Project Manager and Head of Commissioning.
• Track submission status of subcontractor deliverables including test records, reports, RAMS and competency evidence. Review and acceptance remain the responsibility of qualified Commissioning Engineers and Project Management.
• Review and approve subcontractor timesheets against site attendance records and the agreed scope of work.
• Validate subcontractor invoices against approved timesheets, accepted deliverables and order terms, and pass validated invoices for approval to Head of Commissioning and after approval to the Commercial team for payment.
• Record subcontractor performance on safety, quality and timeliness to inform future selection.

Project Coordination

• Monitor issues reported by site personnel and elevate them promptly to Project Managers, setting out the nature of the issue and any likely consequences or impact on the project.
• Work closely with Project Managers and Site Managers to align resource availability with project needs and site readiness.
• Coordinate the maintenance, availability, logistics and calibration status records of commissioning test equipment, materials and specialist resources required by project plans.
• Run regular resource coordination meetings to resolve conflicts between projects and agree actions.
• Act as the operational point of contact for Omexom Business Units on resource matters, including named personnel and site access.

Health, Safety, Quality and Compliance

• Promote a strong safety culture throughout commissioning operations.
• Ensure operational arrangements comply with company procedures, client requirements and relevant legislation.
• Coordinate incident reporting and track corrective actions through to close-out.

• Experience managing subcontractors, including their programmes, deliverables, timesheets and invoices.
• Excellent organisational and coordination skills.
