For 140 years, Chevron has been enabling human progress through reliable, affordable, and ever cleaner energy solutions. However, even industry leaders face operational complexities that challenge traditional decision-making approaches. Nick Wan, Project Execution Advisor at Chevron’s capital projects organization, recognized a fundamental problem: major capital projects were being managed through intuition-based decisions rather than data-driven insights, limiting the company’s ability to optimize complex engineering and construction systems.
Chevron’s remote construction environments present unique operational challenges that traditional planning methods struggle to address effectively. The company’s mine reclamation projects exemplify this complexity, where teams spend decades reconstructing landscapes that took over a century to mine. These operations involve intricate material movement patterns, equipment coordination requirements, and safety considerations that compound throughout the system.
The mine reclamation project featured a particularly challenging area known as “Stairway to Heaven” - an extremely steep section where fully loaded dump trucks descending must coordinate with empty trucks ascending to maintain speed for hill climbing. This operational constraint created queuing patterns and safety risks that required sophisticated analysis beyond conventional planning approaches.
Critical Operational Constraints:
Complex haul truck routing through challenging terrain
Equipment utilization optimization across multiple work areas
Traffic interaction management at critical junctions
Stormwater management under variable operating conditions
Safety protocol coordination between ascending and descending vehicles
Production targets requiring precise resource allocation
Traditional planning methods proved inadequate for modeling these interdependent variables. The Construction Simulation challenge extended beyond simple capacity calculations to encompass dynamic interactions between equipment, terrain, weather conditions, and safety protocols that could significantly impact project outcomes.
Parallel to construction challenges, Chevron faced significant inefficiencies in engineering document production processes. The company’s engineering teams struggled with traditional capacity calculations that failed to reflect the true impact of variability in knowledge work environments. Standard approaches assumed linear task completion and uniform resource utilization, creating unrealistic expectations for project delivery timelines.
The engineering document production workflow involved complex interdependencies where task time variation, resource availability fluctuations, and work-in-process bottlenecks created cascading delays throughout the system. Traditional methods could not accurately model these dynamic relationships, leading to persistent scheduling conflicts and resource allocation inefficiencies.
Engineering Workflow Challenges:
Task time variation that traditional calculations could not accommodate
Resource utilization patterns that deviated from theoretical models
Work-in-process limits that created unexpected bottlenecks
Quality control requirements that introduced additional variability
Interdependent deliverables requiring precise coordination
Client review cycles that disrupted linear workflow assumptions
The need for advanced Workflow Optimization became apparent as Chevron recognized that engineering productivity improvements required sophisticated analytical capabilities that could model the messy realities of knowledge work rather than idealized linear processes.
Chevron partnered with Simio to implement discrete-event simulation technology that could accurately model both construction operations and engineering management workflows. This Construction Simulation approach enabled the company to move beyond intuition-based decision-making toward data-driven insights that revealed system behaviors often hidden from traditional analysis methods.
The construction operations solution utilized Simio’s discrete-event simulation capabilities to create detailed digital representations of Chevron’s mine reclamation activities. The modeling approach incorporated real-world constraints including terrain challenges, equipment limitations, weather variability, and safety protocols that traditional planning methods could not adequately address.
The simulation model accurately represented the mine site layout, including the challenging “Stairway to Heaven” section where traffic coordination proved critical for both safety and productivity. The model tracked individual truck movements, load distributions, and timing relationships that enabled comprehensive analysis of operational scenarios without disrupting actual construction activities.

The Simio implementation explicitly modeled the factors that traditional capacity calculations overlooked, providing accurate insights into actual system performance.
The simulation incorporated realistic task duration distributions, resource availability patterns, and quality control requirements that created the variability characteristic of engineering work environments. This approach enabled identification of actual system bottlenecks rather than theoretical constraints assumed by conventional planning methods.

The simulation models operated as comprehensive testing environments where operational changes could be evaluated without risk of disrupting actual project activities.
The Construction Simulation implementation delivered significant operational improvements across both construction operations and engineering management workflows. Chevron’s data-driven approach revealed system behaviors that were often counterintuitive, leading to safer operations and measurable productivity enhancements that validated the strategic value of advanced simulation technology.
The mine reclamation project achieved a remarkable 6% production improvement through optimized traffic flow management and equipment utilization strategies identified through simulation analysis. While 6% may appear modest, this improvement translates to months of schedule acceleration for a project spanning two decades of reconstruction work.
The simulation analysis revealed that reversing traffic flow patterns to reduce vehicle interactions at critical junctions actually improved overall productivity despite longer individual route distances. This counterintuitive finding demonstrated the value of sophisticated modeling capabilities that could identify optimization opportunities hidden from conventional analysis approaches.

The simulation provided confidence in operational changes that might otherwise have been considered too risky to implement.
The engineering document production analysis identified actual system bottlenecks that differed significantly from theoretical capacity calculations. The simulation revealed that variability in task completion times created work-in-process accumulations that constrained overall system throughput more than individual resource limitations.
The Workflow Optimization analysis enabled Chevron to evaluate targeted improvement strategies that addressed root causes rather than symptoms of productivity constraints. Scenarios exploring variability reduction, resource adjustments, and work-in-process control demonstrated how strategic changes could significantly increase throughput while reducing cycle times.
