Location (On-site, Remote, or Hybrid?): Pasadena, TX (onsite)
Contract Duration: until 06/30/2027
Working hours - 6AM - 4:30PM

Position Summary
The 2027 Turnaround Scheduler is responsible for developing, maintaining, analyzing, and controlling the integrated turnaround schedule using Oracle Primavera P6. The Scheduler works with Turnaround
Management, Maintenance, Operations, Engineering, Planning, Procurement, Materials, and contractors to ensure scope is logically sequenced, schedule-ready, and aligned with execution requirements.
This position is the schedule-control focal point from immediate readiness activities through turnaround execution and closeout. The successful candidate will convert planning and field information into clear
forecasts, risk visibility, look-ahead schedules, and recovery recommendations.

Required Qualifications
• Industrial turnaround, shutdown, outage, or major maintenance scheduling experience.
• Advanced Oracle Primavera P6 knowledge, including WBS, relationships, calendars, constraints, baselines, activity codes, filters, layouts, resources, and schedule calculations.
• Strong Critical Path Method, float, variance, progress-measurement, and forecasting knowledge.
• Experience updating schedules during active field execution.
• Strong Microsoft Excel and reporting skills.
• Ability to communicate across Operations, Maintenance, Engineering, Planning, Procurement, Materials, contractors, and leadership.
• Ability to work 100% onsite and support some overtime based on turnaround needs.

Preferred Qualifications
• Petrochemical, chemical manufacturing, refining, or process-industry turnaround experience.
• Working knowledge of SAP maintenance work orders and work-order readiness.
• Experience with resource-loaded schedules, manpower histograms, schedule comparison, and look ahead reporting.
• Experience integrating contractor and discipline schedules into a master schedule.



Application Profile
Candidates should provide a resume identifying Primavera P6 experience, turnaround or shutdown
assignments, schedule size and complexity, execution-update experience, SAP familiarity, and examples of
critical-path, manpower, look-ahead, or recovery-plan reporting.

Responsibilities:
Primary Responsibilities
Schedule Development and Maintenance
• Develop and maintain the integrated 2027 Turnaround schedule in Primavera P6.
• Integrate maintenance work orders, Operations activities, inspections, engineering and capital nscope, contractor work, pre-turnaround activities, shutdown, execution, startup, and post-turnaround work.
• Build and maintain the WBS, activity coding, calendars, durations, relationships, milestones, constraints, and logic required for a credible Critical Path Method schedule.
• Identify and correct open ends, excessive constraints, unrealistic durations, improper logic, and other schedule-quality issues.
• Maintain approved baselines and controlled revisions as scope and execution plans develop.
SAP Work Order and Readiness Alignment
• Coordinate the P6 schedule with the 2027 Turnaround SAP work-order population and approved scope.
• Reconcile discrepancies among work orders, schedule activities, materials, services, contractor requirements, and execution dates.
• Track dependencies involving procurement, materials, equipment availability, engineering deliverables, Operations preparation, contractor mobilization, and pre-turnaround work.
• Highlight work that is not sufficiently planned, resourced, or ready for execution.
Schedule Analysis and Progress Measurement
• Maintain the data date and update cycle established by turnaround leadership.
• Collect and validate actual starts, actual finishes, remaining durations, progress, and forecast dates.
• Analyze Schedule % Complete, Performance % Complete, total float, critical and near-critical paths, milestone status, and baseline variance.
• Perform schedule diagnostics and troubleshoot incorrect activity, WBS, resource, or progress rollups.
Critical Path, Risk, and Recovery
• Monitor critical and near-critical paths and communicate impacts to overall turnaround duration.
• Assess schedule impacts from scope growth, discovery work, delayed materials, resource
constraints, equipment conditions, and field productivity.
• Develop what-if scenarios, resequencing options, and recovery plans.
Resource and Manpower Planning
• Maintain labor and resource requirements in P6 where applicable.
• Develop manpower forecasts by craft, shift, area, or contractor.
• Identify resource peaks, conflicts, and competing work fronts.
• Support resource leveling and sequence optimization while protecting milestones and the critical path.
Execution Support and Reporting
• Perform frequent schedule updates during execution using validated field progress.
• Support daily schedule-review meetings with planners, supervisors, Operations, contractors, and turnaround leadership.
• Produce 24-hour, 48-hour, 72-hour, and other look-ahead schedules as required.
• Integrate approved discovery and emergent work while preserving traceability and change control.
• Report progress, critical path, milestones, manpower, delays, recovery opportunities, and forecast completion.
Closeout
• Maintain the final as-executed schedule with actual dates, durations, and sequencing.
• Support post-turnaround review, benchmarking, lessons learned, and closeout reporting.
• Recommend improvements to future scheduling standards, templates, updates, and reporting.
