Dulles Corridor Metrorail Project

Phase 1 & Phase 2 Updates

Dulles Corridor Advisory Committee

June 15, 2015

Charles W. Stark

Executive Project Director


Phase 1 Budget Update

• A final contract amount has been negotiated and agreed

with Dulles Transit Partners

• As this agreement amount represents more than 2/3 of the

Phase 1 Project cost, we have been able to forecast the

final cost with a high degree of confidence

• Increased Phase 1 Budget to $76M

• The increase is due to:

100+ Scope changes

Extended completion and testing schedule and resultant longer

staffing durations

Safety & reliability improvements

March Expenditures $ 4.2 Million

Total Expenditures

(Thru March 31, 2015)

$ 2.741 Billion

Forecast at Completion $ 2.982 Billion

Phase 1 Cost Summary

Schedule Extension

• Negotiation Includes 13-month extension for all 153 changes

Includes contractor delay time only; costs to be substantiated

Precludes any contractor constructive acceleration of work based

on design changes

• Cost of Extension Cost impact expected to be known by the end of 2015

• Project has analyzed schedule impacts Major changes occurred in 2013 and early 2014

Schedule Extension

• Revised design work is time consuming

• Unforeseen design changes could result in an additional

modification to the schedule

Goal:

Minimize/stop further changes
