About PCEM

The Authoritative Guide for Queensland Infrastructure Cost Estimating

The Project Cost Estimating Manual (PCEM) is the definitive framework for developing cost estimates across all Queensland transport infrastructure projects. Published by the Department of Transport and Main Roads (TMR), the 9th Edition (November 2025) establishes mandatory standards, processes, and methodologies that ensure consistency, accuracy, and reliability in project cost estimation.

PCEM applies to all project phases from initial planning through to finalisation, covering roads, rail, maritime, public transport, active transport, and intelligent transport systems (ITS). It integrates seamlessly with Queensland's investment frameworks including QTRIP, the Project Assessment Framework (PAF), and OnQ methodology.

PCEM Lifecycle

Project Lifecycle Phases

PCEM aligns with Queensland's five-phase delivery framework. As scope tightens from strategic options to as-built actuals, accuracy bands compress from ±50% to final.

1
Strategic Options

Planning Phase

Establish project need and viability. Develop strategic options and high-level cost ranges to support investment decisions and QTRIP submissions.

Accuracy −30% / +50%
Estimate Type Order of Magnitude
Primary Method Parametric / Analogous
2
Concept Refinement

Concept Phase

Refine options and develop preferred concept design. Produce more detailed estimates to support business case development and preliminary approvals.

Accuracy −20% / +30%
Estimate Type Preliminary
Primary Method Parametric with Analogous
3
Detailed Design

Development Phase

Finalise design to sufficient detail for construction. Develop comprehensive detailed estimates to support final investment decision and budget allocation.

Accuracy −10% / +15%
Estimate Type Detailed
Primary Method Bottom-Up / Takeoff
4
Construction

Implementation Phase

Execute construction and delivery. Monitor actual costs against budget, manage variations, and update forecasts to completion throughout project delivery.

Accuracy −5% / +10%
Estimate Type Control Budget
Primary Method Actuals + Forecast to Complete
5
Closeout

Finalisation Phase

Complete project closeout and capture lessons learned. Reconcile final costs, document variations, and conduct post-implementation reviews to inform future estimates.

Accuracy Final Actuals
Estimate Type As-Built
Primary Method Final Cost Reconciliation

PCEM-Compliant Cost Estimating You Can Trust

As a CE1 pre-qualified consultant under the Department of Transport and Main Roads, Cenex delivers cost estimates that fully comply with PCEM 9th Edition standards. Our team of experienced cost estimators applies PCEM methodologies rigorously across all project phases, ensuring your estimates meet TMR requirements for QTRIP submissions, business cases, and investment decisions.

Our PCEM Capabilities

  • Full Lifecycle Coverage: We develop estimates from Planning phase order-of-magnitude through to Development phase detailed bottom-up estimates, all aligned with PCEM accuracy requirements.
  • P90 Confidence Levels: Our probabilistic risk analysis ensures estimates meet the mandatory 90% confidence level for investment decisions, using Monte Carlo simulation and risk quantification techniques.
  • UNEX Cost Classification: All estimates are structured using the standardized UNEX cost breakdown structure, ensuring consistency with TMR reporting requirements and industry standards.
  • Integrated Risk Management: We embed comprehensive risk identification, assessment, and contingency calculation throughout the estimating process, complying with PCEM risk management protocols.
  • Quality Assurance: Every estimate undergoes rigorous peer review and validation by senior cost estimators, ensuring compliance with PCEM governance and documentation standards.
  • Market Intelligence: We leverage Queensland-specific cost data, contractor feedback, and market trends to ensure estimates reflect current conditions and procurement realities.

PCEM Compliance Deliverables

Our cost estimates include all PCEM-mandated documentation:

  • Comprehensive estimate report with scope definition, assumptions, exclusions, and basis of estimate
  • Detailed cost breakdown by UNEX classification
  • Risk register with quantified cost impacts and contingency calculations
  • Estimate validation checklist demonstrating PCEM compliance
  • Supporting documentation including quantity takeoffs, rate build-ups, and benchmarking data
