Slide #4 Project Title: Howard Signals Project Managing Department: Power & Way Construction * Impact on Customers: During non-rush periods, reduced train speeds when workers are on the Right-of-Way. * Benefit to System: Improve signal system at Howard Interlocking to prevent delays to service. * Benefit to Community: More consistent travel times due to increased reliability. * Impact on Accessibility: N/A * Estimated # of Jobs Created: N/A * Customer Communication Need: Courtesy notification to the Alderman and community about the project. Train announcements about reduced speeds due to workers on the Right-of-Way. * Comparable Projects: Blue Line Signals Project, Loop Signals Project Slide #5 Project Title: Howard Signals Project Managing Department: Power & Way Construction Construction Progress * Printed circuit boards (PCBs) received and installed at Jarvis East, Jarvis West, Howard South and Howard Tower. Software upgrades for Jarvis East and West completed. Installation of the new control panel completed May 1, 2011. Installation of software upgrades at Howard South started 7/25/11 and was completed 9/23/11. Installation of software upgrades at Howard North started 9/26/11 and is forecast for completion 12/23/2011. * Wight-Hill started work 6/10/09, HVAC and roof work is substantially complete. * Paul Borg Construction completed Jarvis Wall Replacement and Abutment Repair. Delay Explanation: * All the DBO boards were returned to Alstom due to a defective component. CTA issued a directive requiring replacement of PCB boards in the fourth quarter of 2010. Delivery of replacement boards is forecast for the first quarter of 2012. The contractor has agreed to replace these boards at no additional cost to the CTA if they receive a time extension to manufacture and test the new boards. * Contractor has not met project milestone dates and CTA has reviewed a recovery schedule and is working with the contractor to determine an acceptable contract time extension at no cost to the CTA. Slide #6 Project Title: Loop Track Renewal Project Managing Department: Power & Way Construction * Justification of Need: The existing track system and the components are beyond their useful life. * Priority of Project: High * Total Project Budget: $53,026,306 * Construction Contract Value: $33,798,984 * Earned to Date: $0.0M * Percent Change Orders to Construction Contract: 0% * Percent Time Used to Date: 19% * Funding Source: 2010 State Capital Program * Estimated Start Date/Estimated Length of Project: NTP issued September 14, 2011, 476 days to Substantial Completion. * Project Manager: Barney Gray (GM); Grace Ohs (PM) * Detailed Overview of Scope: * The project consists of renewal of track on the Wells/Van Buren legs of the Loop, including Tower 18 and Tower 12 Junctions, and Hubbard Curve on the Brown Line. * New components shall include ties, running rail, rail fasteners, guard rail restraining rail, other track material, contact rail, contact rail insulators and anchors, footwalk, track access stairs, control panels, switch machines, rail lubricators, traction power and signal cabling. * Special Track Work includes Tower 12 junction, Tower 18 junction, new double crossover near Washington/Wells and replacement of Left Hand and Right Hand crossovers near Adams/Wabash. Slide #7 Project Title: Loop Track Renewal Project Managing Department: Power & Way Construction Construction Progress * Impact on Customers: 16 weekend line cuts and reroutes. 14 Nightly single tracks and reroutes. * Benefit to System: Reduced maintenance costs, improved headways for revenue service and improved safety. * Benefit to Community: Improved headways for revenue service and improved safety. * Impact on Accessibility: None. * Estimated # of Jobs Created: 140 * Customer Communication Need: Construction Activity Notices will be needed to alert businesses and residents to weekend and night work. Station signage and Customer Assistants will be needed to direct customers during weekend and night. * Comparable Projects: Dearborn Track Renewal, Ravenswood and North Main Line Tie Renewal, Loop Signal Project (Track Renewal on Lake and Wabash) Slide #8 Project Title: Loop Track Renewal Project Managing Department: Power & Way Construction Construction Progress * NTP was issued September 14, 2011. Contractor has made initial submittals including Safety Management Plan, Quality Control Plan, Baseline Schedule and Staffing Plan.

Slide #10 Project Title: Purple Line Viaducts Managing Department: Facilities Construction * Impact on Customers: During non-rush periods, reduced train speeds when workers are on the Right-of-Way. Bus shuttles to replace rail service during weekend line cuts for bridge roll-ins (2) * Benefit to System: Reduce Purple Line slow zones and upgrade aging infrastructure. * Benefit to Community: Faster Purple Line service, improved traffic flow through viaduct and improved aesthetics * Impact on Accessibility: N/A * Estimated # of Jobs Created: 40 * Customer Communication Need: Courtesy notifications to the local Evanston Alderman and community about the project. * Comparable Projects: Church and Main Street Viaduct Replacement Projects Slide #11 Project Title: Purple LineViaducts Managing Department: Facilities Construction Construction Progress * Construction NTP issued August 18, 2011. * H-pile foundations have been installed for the retaining wall located on the southwest side for Greenleaf. The Chicago Avenue retaining wall (1,514 feet) repairs are 98% complete. * Caisson installation at Grove and Greenleaf were completed this fall. One caisson remains to completed at Dempster. Final caisson will be completed in the first quarter of 2012. * New bridges scheduled for installation in the second quarter of 2012.
