Outline • Background • Methodology • Data Collection and Results • Issues • Procedure Guide • Discussion
Background • State highway agencies (SHAs) have identified cost escalation to be a consistent problem • Phase I of NCHRP Project 8-49 • Focused on the larger issue of cost escalation relative to general project cost estimating • Produced Guidance, Report 574, which focused on strategies, methods, and tools • Phase II of NCHRP 8-49 • Target specific area for elaboration – Right of Way
Research Objective Develop an all-inclusive set of right-of-way cost estimation and cost estimation management procedures based on literature and current practice, which integrates cost estimate and cost management steps documented in NCHRP Report 574 to support the right-of-way process.
Research Tasks • Task 1. Update Literature Review • Task 2. Examine and Document Successful Right-of-Way Estimating and Management Practices • Task 3. Develop Methods and Tools for Right-of-Way Estimating and Management • Task 4. Develop Procedures on Right-of-Way Cost Estimating and Management • Task 5. Prepare Report and Right-of-Way Cost Estimating and Management Procedures
MethodologyFramework • Phase I implications • Project development phases • General project cost estimation and estimate management steps • Cost estimating and cost management flowcharts • Tool appendix approach
MethodologyFramework • Impact of Phase I approach on Phase II • Focus on creating a ROW Cost Estimating and Cost Management Procedures Guide – a “how to” • Create more detailed processes for cost estimating and cost management for ROW to support procedure guide • Use some Phase I tools but created a few additional tools focused on ROW using same format and structure
MethodologyData Collection • Literature review • On-site interviews • Interview Protocol • 15 questions • Six areas of interest which focused on different aspects of the cost estimation and estimate management process • Interview Process • Who? • SHAs and other organizations that acquire ROW • Central Office and Region/District perspectives • How? • Use the protocol as a roadmap during interviews • Ask each question relative to the development phase
MethodologyData Analysis Approach • Review of Practices • Critical issues to ROW cost estimation • Successful practices and tools • Flowchart technique • Data was subdivided into four categories: • Inputs (primary and secondary) • Process steps • Outputs • Decisions and loops (cycles within the process)
Data Collection • Interview participants • 7 State Highway Agencies (40 individuals) • 2 Local Public Agencies (5 individuals) • Interview process • Open discussion • Protocol as a checklist • Documents collected • ROW manuals • Unique tools used in practice (i.e. cost estimating systems, estimate documents, spreadsheets) • Early flowchart feedback
Limitations of the Research • Small sample size • Differences between agencies being interviewed: • Large verses small • Organizational make-up – centralized verses decentralized • Project development phases • Terminology and acronyms
ResultsProblem Areas • Damages • Condemnations • Appreciation and other market conditions • Risk analysis and contingency • Early scope definition • Estimating tools • Estimator experience and knowledge
Right of Way Issues • Current practices lack structure and organization. • Communication between ROW personnel and project development team personnel needs to improve. • The ROW cost estimation process is highly dependent on the level of scope definition.
Right of Way Issues (continued) • Planning estimates do not typically involve ROW personnel. • SHAs underutilize risk analysis and the application of contingency in all estimates. • Cost estimation management and cost control are underutilized.
