Two RS&H design-build transportation projects have earned National Awards of Merit from the Design-Build Institute of America (DBIA).
These two projects – the Sisters Creek Bridge replacement in Jacksonville, Fla., and the Rogersville Project Freeway in Greene and Webster Counties in Missouri – are now eligible to win DBIA’s Project of the Year and Excellence Awards, which will be announced in November.
“This year’s DBIA National Design-Build Project/Team Award winners are truly the best of the best. Design-build projects like the Rogersville Freeway Project will not only improve the lives of millions of Americans nationwide, they also provide innovation, time and cost savings at the same time,” said DBIA Executive Director and CEO Lisa Washington. “DBIA is thrilled to honor the Rogersville and Sisters Creek projects among this impressive list of design-build winners while also recognizing these projects’ contributions to their communities.”
The Rogersville Project Freeway in Missouri consisted of converting four miles of U.S. Highway 60 into an access-controlled freeway to facilitate safe and efficient traffic movement. The Missouri Department of Transportation (MoDOT) used a unique procurement strategy that allowed maximum innovation. The RS&H-Radmacher Brothers design-build team devised two grade-separated interchange concepts, which enhanced traffic operations, improved safety, and significantly reduced right-of-way acquisition costs.
For the Sisters Creek Bridge, the RS&H-Archer Western design-build team overcame numerous project challenges, such as poor soils, pedestrian safety concerns and a constrained project site to deliver solutions that the community supports. The team replaced an existing bascule bridge over the Atlantic Intracoastal Waterway (Sisters Creek), with a new 3,300-foot, high-level, fixed-span structure along State Road 105/Heckscher Drive.
“We started out by polling the client (Florida Department of Transportation) with a series of questions to determine what was most important to them, and we also met with stakeholders like the BAE Systems shipyard to understand their concerns and items that were important to the local community,” said RS&H Project Manager Morgan County. “With this knowledge, we worked in partnership with FDOT to establish the project goals and develop the approach and solutions.”
The RS&H-Archer Western team had a solution for every challenge. The crew provided a consistent design speed during construction – a top safety priority for FDOT – by reconfiguring temporary alignments and intersection layouts. The group was also able to develop a plan to keep hundreds of BAE workers, who use a nearby pedestrian bridge daily, grade separated from State Road 105 traffic throughout construction.
To accommodate the mucky soil, the finished bridge is 300 feet longer than it would have been, providing FDOT with a durable corridor that is free of settlement issues. By giving all stakeholders a voice and employing a versatile design-build strategy, RS&H and Archer Western were able to deliver a project that exceeds expectations.
“It was important to ask all the questions and identify the most important issues,” County said. “We ultimately ended up with a bridge that is a win-win for drivers and boaters alike.”
