Applying industry-standard project management structures — WBS, OBS, CBS, and RBS — using Oracle Primavera P6 to plan, schedule, control, and deliver complex engineering projects in the oil & gas and energy sectors.
Effective project management on engineering programmes relies on four interrelated breakdown structures. Together they define work scope, assign accountability, control costs, and manage risk.
In Primavera P6, these structures are integrated into a unified framework — ensuring a direct, traceable relationship between schedule, resources, cost, and risk at every work package level. This is the backbone of Earned Value Management (EVM) and project performance reporting.
A hierarchical decomposition of the total project scope into smaller, manageable work packages. The WBS is the foundation of all planning — defining every deliverable and task required to complete the project. In P6, each WBS node maps directly to activities, resources, and costs.
A hierarchical map of the project organisation — outlining roles, responsibilities, and reporting relationships. The OBS links people and departments to WBS work packages, ensuring every task has a clear owner and accountability chain within the project hierarchy.
A hierarchical breakdown of all project costs by work package or cost category. The CBS links directly to the WBS — each work package maps to its associated budget — enabling precise cost tracking, EVM calculations, and financial reporting throughout the project lifecycle.
A hierarchical representation of project risks organised by risk category. The RBS connects risk owners to specific WBS work packages — enabling systematic risk evaluation, response planning, and ongoing monitoring across the full project schedule in Primavera P6.
Applied Primavera P6 across engineering and construction projects in the oil & gas and power sector — from initial WBS setup and baseline scheduling through progress updates, EVM reporting, and final project closeout.

Building detailed activity networks with logical relationships (FS, SS, FF, SF), assigning durations and constraints, running CPM scheduling, and identifying critical path activities for construction, erection, and commissioning phases of OHTL and UGC projects.
Loading budgets, tracking actual costs against planned values, and generating EVM metrics — BCWS (PV), BCWP (EV), ACWP (AC), CPI, and SPI — to give clients and project managers real-time visibility into cost and schedule performance.
Weekly and monthly progress updates — recording actual dates, percent complete, remaining duration, and physical quantities. Generating S-curves, lookahead schedules, and executive dashboards for Aramco and SEC project reporting.
Maintaining a structured risk register linked to WBS work packages, assigning probability and impact scores, identifying risk owners, and tracking mitigation actions throughout construction and commissioning phases — integrating with the project RBS in P6.
Analysing schedule delays caused by terrain, weather, material procurement, or scope changes — producing time impact analyses (TIA), revised baselines, and recovery schedules to bring projects back on track within contract requirements.

How I apply Primavera P6 across the full project lifecycle on engineering programmes.
Define project scope, build WBS hierarchy, configure OBS, set calendars, and create project in P6 aligned to contract structure.
Create detailed activities, assign durations, set logical relationships and constraints, then run CPM to identify the critical path.
Assign resources to activities, load budgets, link CBS cost accounts to WBS work packages, and set the approved baseline.
Populate RBS categories, link risks to WBS work packages, assign owners, score probability and impact, and document mitigation plans.
Weekly/monthly progress updates — recording actuals, percent complete, and remaining duration. Generate S-curves and lookahead schedules.
Produce EVM performance reports — CPI, SPI, variance at completion — and present findings to Aramco, SEC, and project stakeholders.
Available for project planning, scheduling, EVM reporting, and Primavera P6 support on engineering, construction, and oil & gas projects — based in Saudi Arabia, working globally.
