Slide #11 Project Title: 95th Terminal Justification of Need: The terminal is functionally obsolete and does not allow for optimal bus operations and pedestrian flow. Priority of Project: High Total Project Budget: $240,000,000 Construction Contract Value: Advance Package 1 (AP1) $2,491,291 and Advance Package 2 (AP2) $23,058,838. Earned to Date: AP1: 90% AP2: 30% Percent Change Orders to Construction Contract: 0% Percent Time Used through End of November: AP1: 100% AP2: 64% Funding Source: Federal, State, Bond Estimated Start Date/Estimated Length of Project: AP1: June 6, 2014 (180 days) and AP2: July 24, 2014 (300 days). Designer of Record: Parsons Brinckerhoff Construction Manager/General Contractor: Walsh/II In One JV Project Manager: Grace Ohs, Brittany Dyra (GM) Detailed Overview of Scope: The 95th Terminal Improvement Project will create new south and north terminal buildings at 95th on the Dan Ryan Red Line. The new terminal buildings will create a functional and efficient intermodal facility to enhance bus service and improve pedestrian safety. Scope includes the replacement and expansion of the terminal and platform and the addition of bus and pedestrian bridges. New administrative office space will be built and new bus bays will be provided around the terminal buildings. Slide #12 Project Title: 95th Terminal Impact on Customers: Track closures and weekend station closures during construction. Temporary relocation of certain bus operations to nearby streets during construction phasing. Benefit to System: Improved customer circulation and safety by relieving congestion. Improved bus service and improved pedestrian safety. Benefit to Community: Improved pedestrian safety with new pedestrian bridge over 95th Street, longer train platform extending to the new South Terminal Building. Impact on Accessibility: New south and north terminal buildings with improved accessible routes to buses. Estimated Number of Jobs Created: 3,120 (direct, indirect, and induced), 652 (direct). Customer Communication Need: Required periodic track closures and possible station closures with bus shuttle service. Bus Operations may be relocated to adjacent streets during certain phases of construction. Comparable Projects: Wilson Station. Slide #13 Project Title: 95th Terminal Construction Progress Design: * 90% Design - January 20, 2015 (Ongoing) Pre-Construction Services (Ongoing): * Walsh/II in One JV participates in design meetings and provides constructability reviews, schedules, and estimates for each design phase. Construction - Advance Package 2 Dan Ryan Retaining Walls (Ongoing): * Continued work on the southwest retaining wall. * Installed support of excavation (SOE) for northwest retaining wall. * Jacking pits are being excavated for the jack and bore of fiber optic and electrical ducts under 95th Street on the east and west sides.
