(Silver Award) Wood County I-75 Reconstruction, Perrysburg, Ohio
Contractors: E&B Paving, Inc. | E.S. Wagner Co
Owner/Engineer: Ohio Department of Transportation – District 2
The Wood County I-75 reconstruction project began in July 2014 and continued to late 2016. The project included replacing and widening of pavement, drainage, signage, pavement marking, and new paving. The project also involved construction of one bridge, plus overlaying and replacing decks of existing structures.
E.S. Wagner* was awarded the project and E&B Paving* was the low bidder on the proposed alternate bid paving package, which included 369,203 SY of concrete, including 145,977 CY of 13.5 in. concrete.
The project required meeting annual milestones, a situation impacted by wet weather that threatened the schedule for the first two years.
In the first year, E&B Paving used concrete for temporary 9 in. pavement, which was constructed adjacent to the existing southbound lanes to allow all traffic to be placed in the southbound lanes, which in turn, enabled full width construction of the northbound concrete pavement in 2015.
With the exception of the SR582 on and off ramp and the mainline pavement through the ramps the full width pavement was able to be completed with no outside traffic maintenance.
The SR582 concrete ramps and associated concrete mainline were completed in only 38 days of a 45-day scheduled closure. After the pavement was completed, all four lanes of traffic were switched to the northbound lanes before winter. This set the stage for southbound lanes to be constructed during the third year of the project.
In 2016, the third year of the project, the southbound lanes were built in a mirror image to the previous northbound lanes completed in 2015. Work progressed more quickly because only minimal weather days were experienced. The SR 582 concrete ramps and concrete mainline were again constructed under a 45-day closure, and once again, the work was completed in only 38 Days.
A major challenge was the consistent delivery of wet batch concrete to the paving operations because of car accidents that occurred, sometimes daily, in the bi-directional traffic configuration. In response, the contractor was able to establish a secondary route to allow production to continue in case of other delays.
Trucking also was an issue on the entire project. The DOT had several other projects progressing in northwest Ohio simultaneously, which made it difficult to find enough wet batch to make good productions. Working together, E&B Paving, E.S. Wagner and the DOT we were able to find alternative haul routes and more trucks from E.S. Wagner to assure the highest quality product possible.
In spite of the challenges, E&B Paving was able to achieve 31 percent of incentive dollars for smoothness based on average IRI readings of 54.31 for total project.
Local commuters, truck drivers, and the traveling public will benefit from the added travel lanes, as well as the more durable and sustainable concrete. The smooth ride and the noise reducing longitudinal tines also will provide added benefits for years to come.
(Gold Award) South Lawrence Trafficway (K-10), Douglas, Kan.
Contractor: Emery Sapp & Sons, Inc.
Owner: Kansas Department of Transportation
Engineer: HNTB Corp.
The South Lawrence Trafficway Project (K10) project scope entailed a six-mile, four-lane freeway that moved existing K-10 onto a new alignment, beginning at the south junction of U.S. 59 and the K-10 interchange and reconnected with existing K-10 on the east side of Lawrence.
Emery Sapp & Sons, Inc.* was awarded the project, which also included the creation of more than 300 acres of new wetlands, as well as, bike paths. Also included were relocated sections of Louisiana Street, 31st Street, and Haskell Avenue that run alongside the Wakarusa Wetlands. On the east side of the city, 31st Street was also extended.
The challenges of this project proved to be no match for ESS, which along with 14 subcontractors and 13 suppliers completed the project on time and within budget. The project scope included 21 bridges; 4.35 million CY of grading; 527,000 SY of concrete paving; and 102,000 sq. ft of noise wall. The project also included large scale earthworks, drainage, soil stabilization, and utilities.
The 9.5 in. concrete pavement spanned 6.33 miles or a total of 43.23 lane miles. ESS self-performed approximately 70 percent of the $138 million project. Although the project schedule spanned almost three paving seasons, careful planning, phasing and hard work allowed ESS to complete more than 85 percent of the contract work including paving within the first two construction seasons.
In terms of sustainability, the project used a combination of new technology and old-fashioned hand work to meet two objectives. The first was to meet environmental protective measures for the 927-acre Baker Wetlands.
The contractor worked to avoid disruption to this area that resided within the project parameters in order to protect and preserve the wetlands ecosystem. Special measures included clearing and grubbing by hand, as well as placing recycled timber mats over the wetland area when hauling.
Another critical component was that all equipment used to place foundation stabilization and lower the embankment was required to have less than 5 psi of ground pressure. Also, noise walls and landscaping were added to help create a barrier that would provide increased protection to the ecosystem.
The contractor also turned to state-of-the-art stringless paving to meet the second sustainability objective, which was to use energy-saving equipment/processes.
The project is expected to have an economic benefit to the region of $3.7 billion, the largest of any project under the 10-year, $7.9 billion Transportation Works for Kansas (T-WORKS) transportation program.
