The Backbone of Project Delivery

What is Project Planning & Scheduling?

Project planning and scheduling is the discipline of developing, maintaining, and managing the time-based roadmap that governs how an infrastructure project will be delivered. It encompasses the creation of logic-driven construction programmes, the identification of critical path activities, the allocation and levelling of resources, and the ongoing monitoring of progress against baseline targets.

A well-developed construction programme is far more than a Gantt chart or a contractual obligation. It is the primary management tool that connects every aspect of project delivery, from procurement and resource mobilisation through to commissioning and handover. The programme defines what work will be performed, in what sequence, by whom, and by when. It establishes the framework for measuring progress, identifying potential delays, and making informed decisions about recovery strategies when issues arise.

At Cenex, our planning and scheduling services are delivered by professionals with deep experience in Queensland infrastructure delivery. We develop programmes using Oracle Primavera P6, the industry-standard scheduling platform required by major infrastructure clients including the Department of Transport and Main Roads (TMR) and Queensland Rail. Our schedules are built on sound logic, realistic durations derived from production rate analysis, and genuine resource constraints, ensuring they function as reliable management tools rather than aspirational timelines.

Whether you need a baseline programme for a new project, an independent review of a contractor's schedule, forensic delay analysis to support an extension of time claim, or ongoing schedule management throughout delivery, Cenex provides the planning expertise that infrastructure projects demand. Our integrated approach connects scheduling with risk modelling and cost estimating to provide a complete picture of project delivery performance.

Deliver With Confidence

Why Planning & Scheduling Matters

Robust project planning is the foundation of successful infrastructure delivery. Projects with professionally developed and maintained schedules consistently outperform those relying on informal or poorly structured programmes.

Schedule Certainty

Realistic programmes built on proper logic, production rate analysis, and genuine resource constraints provide genuine schedule certainty for project planning, stakeholder commitments, and funding milestones. A well-developed baseline programme establishes achievable targets that the entire project team can work towards with confidence.

Early Warning of Delays

Proactive progress monitoring against a properly maintained baseline identifies potential delays and critical path impacts early, enabling corrective action before minor slippages compound into major programme overruns. Regular schedule updates provide the visibility needed to manage delivery proactively rather than reactively.

Resource Optimisation

Resource-loaded schedules enable efficient allocation of personnel, equipment, and materials across project activities. Resource levelling ensures that the programme reflects genuine delivery capacity, preventing unrealistic concurrent activities and enabling accurate workforce and equipment mobilisation planning.

Commercial Protection

A properly maintained baseline programme provides the essential foundation for delay analysis and extension of time claims. When delays occur, a well-documented schedule history enables rigorous forensic analysis that protects your commercial position in dispute resolution, adjudication, and arbitration proceedings.

Informed Decision-Making

What-if analysis and scenario modelling enable informed decision-making about acceleration options, sequencing changes, and recovery strategies. When project circumstances change, a robust schedule allows rapid evaluation of the impact of different options on cost, resources, and completion dates.

Stakeholder Communication

Well-structured programmes provide clear communication tools for stakeholders at all levels. From detailed look-ahead schedules for site teams to executive summary milestone reports for project boards, a properly developed programme supports effective progress reporting and expectation management throughout the project lifecycle.

Timing Your Engagement

When You Need Planning & Scheduling Services

Professional scheduling support delivers value at every stage of the project lifecycle. The optimal time to engage depends on your project phase and specific requirements, but early engagement consistently produces the best outcomes.

Pre-Construction: Getting the Foundation Right

During the business case, procurement, and pre-construction phases, a professionally developed programme establishes realistic delivery timeframes, informs funding decisions, and provides the baseline against which all future progress will be measured. Investing in quality scheduling at this stage prevents the cascading problems that arise from unrealistic programmes being set as contractual benchmarks.

During Delivery: Maintaining Control

Throughout construction delivery, ongoing schedule management provides the progress visibility and early warning capability that project managers need to keep complex projects on track. Regular schedule updates, critical path analysis, and look-ahead planning ensure that issues are identified and addressed before they become costly delays.

Post-Completion: Protecting Your Position

When projects experience delays, forensic scheduling provides the rigorous analysis needed to support extension of time claims, assess liquidated damages exposure, and quantify prolongation costs. Expert delay analysis that follows recognised methodologies is essential for protecting your commercial position in claims and dispute resolution proceedings.

How We Deliver

Our Planning & Scheduling Methodology

Cenex follows a structured approach to programme development that ensures every schedule we produce is logic-driven, resource-realistic, and fit for purpose as a genuine management tool.

1

Scope Definition & WBS Development

We begin by understanding the full scope of work and developing a comprehensive Work Breakdown Structure (WBS) that captures all project activities. This foundation ensures complete coverage and provides the framework for logical activity sequencing.

2

Logic Development & Sequencing

We establish logical relationships between activities based on physical dependencies, resource constraints, and construction methodology. Proper logic development is critical to producing a schedule that accurately reflects how the project will be built in the field.

3

Duration Estimation & Resource Loading

Activity durations are derived from production rate analysis, historical data, and crew composition, not arbitrary estimates. Resources are assigned to activities and levelled to reflect genuine delivery capacity, ensuring the programme is achievable with available resources.

4

Critical Path Analysis & Optimisation

We identify the critical path and near-critical paths, analyse total float distribution, and optimise the schedule to meet target dates where possible. This analysis reveals the activities that drive the completion date and where schedule risk is concentrated.

5

Baseline Approval & Ongoing Management

Once approved, the baseline programme becomes the reference point for all progress monitoring. We provide ongoing schedule updates, progress reporting, and critical path tracking to maintain schedule integrity throughout project delivery.

Comprehensive Capabilities

Our Planning & Scheduling Services

From baseline development through to forensic delay analysis, Cenex provides the full spectrum of planning and scheduling services that infrastructure projects require.

Baseline Programme Development

Development of comprehensive baseline programmes using Critical Path Method (CPM) scheduling in Primavera P6 or Microsoft Project. Our baseline programmes are built on sound logic, realistic durations derived from production rate analysis, and proper resource loading. We develop programmes that comply with client-specific scheduling specifications, including TMR and Queensland Rail requirements for programme submissions.

Programme Review & Audit

Independent review and audit of contractor programmes to assess logic integrity, duration reasonableness, resource adequacy, critical path validity, and overall achievability. Our programme reviews identify scheduling issues including open-ended activities, negative float, artificial constraints, unrealistic concurrency, and logic gaps that undermine programme reliability. We provide detailed reports with recommendations for programme improvement.

Resource Loading & Levelling

Assignment and optimisation of labour, equipment, and material resources across programme activities. Resource levelling resolves over-allocations to produce a schedule that reflects genuine delivery capacity. Resource-loaded schedules enable accurate cash flow forecasting, workforce planning, equipment mobilisation scheduling, and progress measurement using earned value techniques.

Progress Monitoring & Reporting

Regular schedule updates and progress reporting to track project performance against the approved baseline. We produce meaningful progress metrics including earned value analysis, critical path tracking, float consumption monitoring, and look-ahead schedules. Our reporting identifies trends and potential issues early, enabling proactive management rather than reactive crisis response.

Delay Analysis & Forensic Scheduling

Expert delay analysis using recognised methodologies including Time Impact Analysis (TIA), As-Planned vs As-Built comparison, Windows Analysis, and Collapsed As-Built analysis. Our forensic scheduling services support extension of time claims, liquidated damages assessments, prolongation cost quantification, and dispute resolution. We produce analysis that is rigorous, well-documented, and capable of withstanding scrutiny in adjudication and arbitration proceedings.

Recovery Schedule Development

When projects fall behind programme, we develop recovery schedules that analyse realistic options for acceleration and schedule recovery. This includes assessing the feasibility and cost of additional resources, extended working hours, revised sequencing, and scope re-prioritisation. Our recovery programmes are practical and achievable, providing a credible path back to programme compliance.

Schedule Risk Assessment

Probabilistic schedule analysis using Monte Carlo simulation to determine the likelihood of achieving target completion dates. Activity durations are modelled as probability distributions to produce a range of possible completion dates with associated confidence levels (P50, P80, P90). Integrated with our risk modelling services, schedule risk assessment provides a complete picture of project time and cost uncertainty.

What-If Scenario Analysis

Modelling of alternative delivery scenarios to support informed project decision-making. We evaluate the schedule impact of different sequencing options, resource strategies, design changes, and external constraints, enabling project teams to compare options objectively and select the approach that best balances programme, cost, and risk considerations.

Common Questions

Frequently Asked Questions

Answers to common questions about project planning, scheduling, and how professional programme management benefits infrastructure projects.

What is construction project scheduling?

Construction project scheduling is the process of developing a detailed, logic-driven programme that defines the sequence, duration, and interdependencies of all activities required to deliver a project. A properly developed construction schedule uses Critical Path Method (CPM) analysis to identify the longest sequence of dependent activities, enabling project teams to understand which tasks drive the completion date and where float exists for flexibility. The schedule serves as both a planning tool during pre-construction and a management tool during delivery, providing the basis for resource allocation, progress monitoring, and commercial management.

Why is Primavera P6 the preferred scheduling tool for infrastructure projects?

Oracle Primavera P6 EPPM is the industry standard for large-scale infrastructure project scheduling because of its advanced capabilities for managing complex, multi-project environments. P6 supports unlimited activity levels, sophisticated resource loading and levelling, multiple baseline comparisons, and enterprise-wide portfolio management. Major infrastructure clients in Queensland, including TMR and Queensland Rail, require contractors to submit programmes in P6 format. Its robust reporting capabilities and integration with risk analysis tools make it essential for projects requiring rigorous schedule management and probabilistic analysis.

What is delay analysis and when is it needed?

Delay analysis, also known as forensic scheduling, is the systematic assessment of what caused a project to be delayed beyond its contracted completion date. It is needed whenever a project experiences delays that may give rise to extension of time (EOT) claims, liquidated damages exposure, or prolongation cost claims. Delay analysis methodologies include Time Impact Analysis (TIA), As-Planned vs As-Built comparison, Windows Analysis, and Collapsed As-Built analysis. The choice of methodology depends on the quality of available schedule data, the contract requirements, and the complexity of the delays.

How does resource loading improve schedule reliability?

Resource loading assigns specific quantities of labour, equipment, and materials to each schedule activity, transforming a logic-driven programme into a resource-constrained schedule that reflects real-world delivery capacity. Without resource loading, a CPM schedule may show activities occurring simultaneously that cannot physically be performed concurrently due to resource limitations. Resource levelling adjusts the schedule to resolve over-allocations, providing a realistic view of achievable progress and enabling accurate cash flow forecasting and workforce planning.

What is a schedule risk assessment?

A schedule risk assessment applies probabilistic analysis to a project programme to determine the likelihood of achieving target completion dates. Using Monte Carlo simulation, activity durations are modelled as probability distributions rather than single-point estimates. The simulation runs thousands of iterations to produce a range of possible completion dates with associated probabilities (P50, P80, P90). This analysis identifies which activities and risks have the greatest influence on schedule outcomes, enabling focused mitigation efforts on the most impactful schedule drivers.

At what project stage should professional scheduling support be engaged?

Professional scheduling support delivers value at every stage of the project lifecycle, but early engagement provides the greatest benefit. During the planning and business case phase, a programme establishes realistic delivery timeframes. At the procurement stage, a detailed baseline supports tender evaluation. During construction delivery, ongoing schedule management provides progress visibility. Post-completion, forensic scheduling supports claims resolution. The cost of professional scheduling expertise is typically a fraction of a percent of project value, while poor scheduling can lead to delays costing millions in prolongation, liquidated damages, and lost productivity.
