permeability, requiring testing for every placement. The designer also specified corrosion-resistant reinforcing (CRR) steel. A requirement in Virginia, CRR steel adds to the long-term durability and less steel can be used because of the higher-grade steel used to satisfy the CRR requirements. " A s t h e o w n e r 's C E I c o n s u l t a n t , RS&H understands its role with long- term durability by embracing these innovations and providing the level of oversight to ensure they are met," says Sweeney. "We understand that our clients rely on us to make sure they are getting what they paid for." I n n o v a t i o n s c o n t i n u e w i t h e v e r y project, such as the Wekiva Parkway Section 6 project just getting underway in Orlando, Fla. Site conditions and environmental concerns made a cast-in- place segmental box-girder design the best choice, Barry says. The 2068-ft-long structure will be the first in the country to use new post-tensioning technology involving flexible filler instead of grout. "It was significant for us to be chosen to provide construction oversight for this project, as it signifies our commitment to the industry and our service to our clients to help further the industry by embracing new technologies," Barry says. "It also expands our segmental and major concrete bridge resume, positioning us for further growth." Geiger also looks forward to digging into this new concept. "The segmental industry continues to move forward with new technologies, and we're right there with them. We take pride in the fact that FDOT is showing great faith in us to oversee this new technology. It could be the future; we don't know yet. But it'll be exciting to see how it works." ____________ For additional photographs or information on this or other projects, visit www. aspirebridge.org and open Current Issue. RS&H was founded in 1941 by engineers George B. Hills and John F. Reynolds and architect Ivan H. Smith. They decided to combine architectural and engineering capabilities to create a firm that would be more efficient than their separate small firms. With World War II imminent, they focused on military projects, including what would become NASA's Cape Canaveral facility in Florida. After the war, the firm designed power plants, airports, and industrial facilities, adding offices throughout the Southeast. In the 1960s, it worked closely with NASA's manned spaceflight program and the U.S. Air Force's missile program. Over the next 20 years, it added several subsidiaries and affiliates, increasing staff and offices across the United States. RS&H returned to an employee- ownership model in 1990. Today, the firm has 1089 employees in 50 offices focused in six markets: transportation, aviation, aerospace, corporate, defense, and health and science. It ranks 70th in Engineering News Record's Top 500 Design Firms. It also ranks 11th in Roads & Bridges' Top Bridge Design Firms.
