Outline • Background • Methodology • Data Collection & Results • Issues • Procedure Guide • Discussion
Background • State highway agencies problems with project cost escalation. • Phase I of NCHRP Project 8-49 • Focused on cost escalation relative to general project cost estimating • Product - Guidance, Report 574, focuses on estimating strategies, methods, & tools

Phase II of NCHRP 8-49 • Targeted – Right of Way • Cost estimation and • Cost estimation management

Research Objective Develop inclusive right-of-way cost estimation and cost estimation management procedures based on literature and current practice, that integrates with the cost estimate steps documented in NCHRP Report 574
Framework • Phase I Implications • Project development phases • General project cost estimation & estimate management steps • Cost estimating & cost management flowcharts • Tool appendix approach
Framework • Impact of Phase I on Phase II • Focus on creating a ROW Cost Estimating & Cost Management Procedures Guide – a “how to” • Create more detailed processes for cost estimating & cost management for ROW to support procedure guide
Framework • Impact of Phase I on Phase II • Use some Phase I tools but created additional tools focused on ROW using same format and structure as in the NCHRP Report 574
Data Collection 1. Literature review 2. On-site interviews Interview Protocol Six areas of interest that focused on different aspects of the cost estimation & estimate management process
Data Collection Interview Process Who? SHAs and other organizations that acquire ROW Central Office and Region/District perspectives How? Ask questions relative to project development phase
Data Collection Documents collected • ROW manuals • Unique tools used in practice (i.e. cost estimating systems, estimate documents, spreadsheets) Early flowchart feedback
Data Analysis • Review of Practices • Critical issues to ROW cost estimation • Successful practices and tools
Data Analysis • Flowchart technique • Data subdivided into four categories: • Inputs (primary and secondary) • Process steps • Outputs • Decisions and loops(cycles within the process)
Limitations • Small sample size • Differences between agencies: • Large verses small • Organizational make-up ― centralized verses decentralized • Project development phases • Terminology and acronyms
Results Problem Areas • Damages • Condemnations • Appreciation & market conditions • Risk analysis & contingency • Early scope definition • Estimating tools • Estimator experience & knowledge
Right of Way Issues • Current practices lack structure and organization. • Communication between ROW personnel and project development team needs to improve. • The ROW estimation is highly dependent on scope definition.
Right of Way Issues • ROW planning estimates typically not prepared by ROW staff. • SHAs do not utilize risk analysis and the application of contingency to all estimates. • Cost estimation management and cost control are underutilized.

Risk Analysis Analysis of Risk and Uncertainty Analysis of uncertainty involves quantifying identified risks. Risk analysis is used to prioritize identified risks for mitigation, monitoring, and control purposes. Risk analysis can be extremely helpful for understanding project uncertainty and setting appropriate contingencies.
Risk Analysis What Is It? In the context of cost estimation, this tool quantifies project risk and uncertainty to provide a better understanding of contingency and the ultimate project cost.
Risk Analysis Why? Highway project delivery, particularly the estimation of right-of-way cost, is a complex task heavy with uncertainty. What Does It Do? This tool quantifies the effect of potential risks in terms of their consequences to cost and schedule.
Risk Analysis When? Risk analysis can be used throughout the project development process. Examples Caltrans has documented a qualitative risk analysis procedure: Project Risk Management Handbook: Threats and Opportunities,May 2007
Risk Analysis Tips Conduct the risk analysis early in the project development process. Resources Project Risk Management Handbook: Threats and Opportunities, Caltrans, www.dot.ca.gov/hq/projmgmt/guidance_prmhb.htm
Guide Conclusions Structured Approach Collaborative Atmosphere Key Principles • Create an environment for success • Create procedures for establishing a Baseline ROW Cost Estimate
Guide Conclusions Key Principles • Create processes to identify risk and for setting contingency • Require ROW reviews • Create ROW cost control mechanisms • Support good communication practices
Magic Bullets Stick to the process ―a process that: • Considers risk – identify and mitigate • Requires reviews and approvals • Involves updating the estimate when new or more detailed information is available.
Communicate estimate consistency and accuracy to the project team and management
