2 Presentation Outline Overview of the Project Scope ABC Project Planning ABC Design & Construction Construction / Contractor Perspective

3 FHWA Every Day Counts Initiative Designed to identify and deploy innovation aimed at shortening project delivery, enhancing the safety of our roadways and protecting the environment.

4 RIDOT Goals Safety Innovative Using Accelerated Bridge Construction Methods Precast substructure, PBE s Minimize Time Road closure eliminated phasing Cost Effective Balanced accelerating construction with user costs Efficient Intermodal Transportation Network Restored link from East Bay to Providence Crossing

5 RIDOT Goals (Continued) Public Attentiveness Minimize Public Impact Replace in 20 days with ABC, 2+ years conventional Increase Public Awareness City Officials Attended Council Meeting Outreach through multiple media venues: radio, social, paper, internet, link to web cam on DOT website, door to door with handouts

6 Overview of the Project Scope Accelerated Replacement of Bridge No. 465 I-195 On-Ramp (DR-2) over Warren Avenue

7 Site Location WB I-195 EB I-195 TAUNTON AVE N Bridge 465

8 Summary of Existing Bridge BRIDGE SUPERSTRUCTURE: Precast Prestressed Concrete I-beams and Reinforced concrete Tee beams BRIDGE SPAN: 3 simply supported spans of /8 (span 1) 61-1½ (span 2), /8 (span 3) BRIDGE WIDTH: SUBSTRUCTURE: 23 0 curb to curb, 28 2 out to out Unreinforced concrete gravity abutments on piles and two column reinforced concrete bents on piles BRIDGE SKEW: 25 o 9 6 BRIDGE SIDEWALKS: ROADWAY SURFACE: Safety walks on both sides 3 bituminous wearing surface

9 Existing Bridge Condition

10 Overview of Project Scope Bridge 465 Replace Superstructure & Piers Evaluate Abutments Consider Feasibility of ABC Methods I-195 Westbound On-Ramp Approaches Full Depth Construction for Bridge Replacement Guardrail Replacement Pavement Milling & Overlay Warren Avenue Sidewalk Replacement Wheelchair Ramp Upgrade Pavement Milling & Overlay WARREN AVE ON-RAMP TAUNTON AVE Bridge 465 N

11 Why ABC for New Bridge? No phase construction option due to narrow 23 0 roadway width Significant reduction of bridge closure time Detour options available Reduce impact to traffic and the public

12 ABC Project Planning Accelerated Replacement of Bridge No. 465 I-195 On-Ramp (DR-2) over Warren Avenue

13 FHWA Framework for Decision-Making

14 Rapid Onsite Construction Factors High Traffic Volumes YES Emergency Replacement Necessary YES Evacuation Route NO Required Lane Closures / Detours YES Impact on Total Project Critical Path YES Use Prefabrication

15 Closure of I-195 On-Ramp (Bridge 465) One Month Duration Closure of On-Ramp over Warren Ave

16 Closure of Ramps Two Weekends Closure of I-195 Off-Ramp (Exit 5) Two Weekends Closure of On-Ramp over Warren Ave & Closure of Warren Avenue below Bridge 465 (including sidewalks)

17 Milestones #1 Weekend Closure Demolition Re-Open Warren Ave and Exit 5 Ramp #2 Weekend Closure Place Superstructure Re-Open Warren Ave and Exit 5 Ramp #3 One Month Duration - Complete Bridge Construction Re-open On-ramp Traffic Over Warren Avenue #4 Substantial Completion Complete All Work for Bridge 465 And Warren Avenue.

18 Incentive / Disincentive #1 Completion of Weekend Closure #1 - $400 Per Hour Maximum Incentive $20,000 #2 Completion of Weekend Closure #2 - $400 Per Hour Maximum Incentive $20,000 #3 Bridge Open to Traffic $12,000 Per Calendar Day Maximum Incentive $120,000 Liquidated Damages Substantial Completion $1,500 Per Day
