• Lead baseline and re‑baseline processes, ensuring schedule alignment with scope changes and project control procedures.
• Monitor and report progress through earned value analysis, S‑curves, KPIs, and critical path tracking to support performance management.
• Identify schedule risks and opportunities, integrating mitigations into project plans and advising project teams on schedule impact.
• Coordinate closely with multi‑discipline teams (engineering, procurement, production) to validate planning assumptions and logic.
• Mentor junior planners and support continuous improvement, driving planning standards and best practice across the business.
• Ensure compliance with client requirements and internal governance, including support for audits, reporting, and security standards.

In Addition

• You will take ownership of the planning lifecycle from initial baselining through to project closeout.
• Develop and manage detailed schedules in Primavera P6, incorporating engineering, procurement, construction, commissioning, and client interface activities.
• Lead critical path analysis and ensure timely identification of schedule risks and mitigation actions.
• Maintain and report progress using S‑curves, earned value (EVM), and forecasting tools.
• Manage the baseline and re‑baseline process, ensuring all changes are controlled and auditable.
• Collaborate with Project Managers and functional leads to validate assumptions and schedule logic.
• Prepare and present project planning reports and dashboards to internal and client stakeholders.
• Integrate planning with risk management activities and incorporate mitigation plans into the schedule.
• Support planning process improvements and continuous development across the project planning function.
• Provide mentorship to junior planners and contribute to team development.
• Support integration with ERP systems for resource and cost tracking.

Bid & Tender Support

• Work closely with the bidding and estimating teams to develop realistic, resource‑loaded bid schedules aligned with project execution strategies.
• Analyse tender documents and client requirements to ensure alignment of bid plans with project scope and constraints.
• Conduct scenario planning and schedule optimisation to support commercial strategy during the tender phase.
• Provide schedule inputs for bid submissions, including programme narratives, integrated planning approval and planning slide pack containing the noted risks.
• Support handover from bid to project execution teams, ensuring smooth transition and continuity of planning information.
