FOCUS LOGISTICS EXPERTS Walsh Group excels at constructing complex projects, complicated designs to meet logistical challenges by Craig A. Shutt. The Walsh Group has gained a reputation for handling complex, signature bridges and creating innovative techniques that influence later designs. But project complexity often goes beyond unique designs to encompass scheduling issues and constructability challenges on major multi-bridge projects. Walsh also excels at those needs, as proven by its recent contract with the Pennsylvania Department of Transportation (PennDOT) to replace 558 bridges in the state by the end of 2017. Nearly all of them will feature concrete designs.

Walsh is part of Plenary Walsh Keystone Partners, comprising Plenary Group, Granite Construction Co., HDR Engineering, and Walsh (Walsh Investors, Walsh Infrastructure Management, and Walsh Construction). The group is not only designing and constructing the bridges, but it is also financing and maintaining them for 28 years. At least 548 of the bridges will feature concrete beams and concrete box culverts, says Arik Quam, project manager in the Pittsburgh office. Approximately 428 will consist of concrete box girders, spread girders, or I-beams, while about 120 will be composed of precast concrete box culverts. Walsh's concrete bridge design was a key to their winning proposal, he notes. "As we have to maintain the bridges, we wanted to ensure they were low
