CEVP®• A risk-based estimating process.

• A statistically valid method for expressing cost and schedule estimates as a range.

• Comprised of two components: base and risk/opportunities.

• Base estimate and schedule if project goes as planned.

• Risk register.

• Scalable.

• Use independent subject matter experts to minimize bias.

Construction strategies workshop members review materials from the WSDOT project team.

Outcome = Risk based budget

PM Lessons Learned

• Develop Project Risk Register and update regularly

• Develop effective contracting structure.

• Account for risks and inflation in estimates.

• Manage project as a strong owner.

• Identify and develop risk management plans.

• Engage experts with national and international tunneling experience in urban environments.

• Continue risk management beyond design

Managing

RISK

PM Lessons Learned

• Ensure that design reviewers have a comprehensive understanding of the project.

• Be accurate in coordinating design management personnel.

• Ensure that design-builder’s design and construction personnel coordinate after the contract award.

• Require the design-builder to provide design definition submittals.

• Involve all the project stakeholders and educate them about the project and design build procedures.

Design-Build Contracting Lessons Learned

PM Lessons Learned

• Use of risk-based cost estimating (CEVP) allowed better understanding of cost drivers and informed risk allocation.

• Having the right owner team and experts was essential.

• Pre-qualification and best value selection process critical.

• Risk sharing, shared allowances and incentives structured protection for the contractor, reduced bid contingency.

Design-Build Contracting Lessons Learned

• Draft to final RFP allowed a very interactive and fair process for the project.

• “Upset price” forced contractors to be very competitive.

• Contracted with “best value” bidder.

PM Lessons Learned

• Right of Way Cost and Schedule Risk

• Settlement and vibration

• Buildings

• Major structures

• Utilities

• Environmental

• Noise

• Historic/Cultural resources

• Contaminated soil & groundwater, HAZMAT, UST’s, etc.

ROW Acquisition and Construction Impacts Analysis

PM Lessons Learned

Future Development Above the Tunnel• Load limit would allow development that

exceeds current land use regulations.

• Future development or redevelopment would be unique to each property and depend on:

• Development size and design.

• Tunnel alignment below property.

• Distance between ground surface and top of bored tunnel subsurface parcel.

Industry Resource and Workforce

PM Lessons Learned

• Forecast scarce skill sets. Labor rates will be higher than normal

• Plan for timely / most efficient means of contracting for scarce labor

• Think globally when getting true experts; peer projects

• Create a staffing or “workforce” plan for the program

Cost Estimate and Risk Validation Process

PM Lessons Learned

• Cost Estimate – Decentralized vs Centralized

• Risk Development and Unification of cost and schedule through Probabilistic Risk Review (CEVP®)

• Establishing Baseline

• Identify changes to:• Scope (Configuration Change)• Cost• Schedule

• Formally document changes.• Study change impacts.• Bring changes to management attention.• Formalize decisions on changes.• Update baselines & implement the change.

Configuration and Trend/Change Management Program: Objectives

Configuration and Trend/Change Management (Baseline Control)

Progress Measurement

PM Lessons Learned

• Management Support & Communicating the Business Need

• Project Management Factors• Prior Development of Other

Supporting Project Controls Capabilities

• Early Establishment of Procedures• Integration of Contract Language to

EV Requirements• Not all Work Scopes are Suitable for

EV Measurement

Reporting - Stakeholder

PM Lessons Learned

Reporting – Risk Retirement and Contingency Drawdown

PM Lessons Learned

Expert Review Panels / External Experts/ Oversight

PM Lessons Learned

• You can count on external oversight on major programs• Be open and transparent. Admit problems; they should be on the

risk register• Supporting systems can quickly retrieve information• Review reports from oversight groups and look for issues concerning

which you’ll have to answer

Tunnel features:• Two 11-foot lanes in

each direction• 8-foot and 2-foot

shoulders• Modern safety and

traffic systems• No mid-tunnel

entrances or exits

Final product: SR 99 tunnel
