Ohio Department of Transportation John R. Kasich, Governor Jerry Wray, Director PIAC HAM-275-10.57; PID 82976 Major Rehab - Design Build Project Letting Date: Sept. 26, 2013 Completion Date: Nov. 1, 2015 Estimate: $33 - $35 million Jennifer Elston, Brandon Collett, Scott Kraus District 8 March 29, 2013
6 BRIDGE: HAM-275-1070R Proposed Work which will impact Traffic: Replace both approach slabs Replace both expansion joints Replace portion of both backwalls Deck overlay Other work with minimal/no Traffic Impact New Pressure Relief joint west of the structure Reface/replace parapets Refurbish beam bearings Trim beam ends Structure Sealing and Painting
10 BRIDGE: HAM-275-1070R HAM-275-1070R Costs, MOT, and impacts Total Bridge Costs: $6 Million (8 structures) Lane closures will be in accordance with PLCM, except for bridge work Original scope bridge work – Abutment replacement; 90 day part- width closure; excessive queue. MOTEC, OSE, District, OGE- Benefit to not replace abutment worth Risk. Revised scope bridge work – 2 MOT options 7 day part-width closure PRO’s = Reasonable Cure times, better end product. Not reconstructing abutment saves $230,000 CONS’s = 12 mile queue. Multiple weekend part-width closures; queue is within threshold limits PRO’s = Queue is within threshold or very close to threshold limits. CON’s = Accelerated Construction and reduced Cure, cracking and shorter service life is at risk. Not reconstructing abutment only saves $130,000 District Choice – Weekend closures maintaining one 11’ lane
11 BRIDGE: HAM-275-1070R Revised HAM-275-1070R Bridge Scope (Assumes work is limited to weekends only) Changes to scope are shown in orange Remove 1” of original deck and replace with 1 ¾” SDC overlay using weekend overlay specifications. Replace Reface non-crash tested GM shaped barriers. Replace sliding plate expansion joints with strip seal expansion joints including top of backwall and portion of deck. Replace rear abutment that has moved laterally and longitudinally. Widen beam seat by 6”. Relocated bearings forward 3”. Trim beam ends by 2” and set new expansion joint to accommodate 2” of movement. Replace approach slabs using MS Concrete. Construct Pressure Relief Joints. Sleeper slabs may be precast or FS concrete. Seal concrete with EU and paint steel with OZEU.
12 Communications Plan Outlets to Communicate with the Public Establish a webpage for the I-275 project with the following information: Project Timeline Link to sign up for project updates by e-mail Project info including closures, detours and alternate routes Contact info for PIO Short videos showing closure/detour routes and what motorists can expect to see when encountering the closures and ease of following detour. Video to be posted a week in advance of any closures/detours. Communications Plan
13 Communications Plan Message Boards/ Dynamic Message Signs Media Blitz Contact local media and invite to a location near the project to explain the upcoming work required by the project and impacts to traffic. Social Media Communicate impacts via social media, provide a link to the webpage and link to signing up for e-mail updates. E-mail Blast Provide updates to e-mail groups as often as necessary through completion of the project. Communications Plan
