Profiles and Testimonials: Bill Maize |

 | |
Bill Maize VP of Sales has been in the concrete industry since 1986; he began his career in aggregates then moved on to be the plant manager of a large concrete company. In 1991 Bill began his career in admixtures and soon found that his technical expertise would be heavily relied upon by customers, DOT's, and engineers alike. Bill has devoted much of his time to various industry Associations and Universities. He has been a guest lecturer at Bowling Green State University, the University of Toledo and many State association seminars. He has served as an adjunct professor at Rhodes State College in Lima, OH, as well as an ACI level 1 Concrete Certified Instructor. He has served on the Ohio Ready Mix Concrete Futures Board of Directors and assisted in youth education through involvement with the Concrete for Kids promotion committee. He is a NRMCA Level II technician, and ACI certified Flatwork Technician. Bill is also a member of ACI – International and is currently serving on ACI 201 Concrete Durability Committee. Bill has worked on projects of all sizes and shapes, from HPC bridges, super flat factory floors, color, & flowable fill, to a slip form silo 300 feet high that consisted of a 14 day continuous pour. Inside that silo 16 compartments were cast simultaneous to the walls. Prior to his employment with Premiere, Bill worked on the construction of the I-280 Veterans' Glass City SkyWay Memorial Bridge, which crosses the Maumee River in Toledo, Ohio. Bill considers that project to be one of the most challenging projects of his career. The bridge had many unique features; one was that it was a segmental unit requiring high strength, with a quick turnaround schedule. The precast requirements were 6000 psi in 3 days in order to keep up with scheduling demands. Another was the color specification. This bridge was a showcase that had incentives and deductions associated with color consistency. Bill and the producer analyzed many different options but settled in on one mix for the entire project. Different applications would be manipulated through different admixtures with different dosages, for example piers, drilled shafts, segmentals etc. The whole time it was important to maintain a consistent water cement ratio. The team decided on a heavy contribution of GGBFS to help enhance the desired white look of the bridge.. The Ohio Department of Transportation (ODOT) and the city of Toledo began planning the bridge in April 1999, and construction began in spring 2001. The project consisted of building an 8,800 foot (2,700 m) span across the Maumee River low-lying land. The main span over the Maumee River is a cable-stayed type bridge with a single pylon and two spans 612'-6" (200 m) on each side of the pylon. The main span approaches are approximately 4,000 feet (1,220 m) north of the river and 3,350 feet (1,020 m) south of the Maumee. The bridge opened to traffic on June 24, 2007. The bridge carries three lanes of traffic in each direction. The road surface reaches a height of 130 feet (40 m) above the surface of the Maumee River. The bridge is the most expensive project ever undertaken by ODOT, costing approximately $237 million. The main attraction of the bridge is the single pylon which contains 384 light emitting diodes (LEDs) that are capable of creating 16.7 million potential color combinations. The LEDs shine through all the glass facing on all four sides of upper 196' feet of the main pylon. These lights should be visible from up to 3 miles (5 km) away. The community selected a "glass" theme for the bridge design, choosing to honor the region's heritage in the glass manufacturing industry. The bridge was designed by FIGG (Figg Bridge Engineers, Inc.) for the Ohio Department of Transportation. The bridge is one of two installations of a new cable-stayed cradle system that eliminates anchorages in the pylon by carrying the stays from anchorages in the bridge deck, through the pylon and back to anchorages in the deck. Each strand acts independently, allowing for the selective removal, inspection and replacement of the strands. "The initial start of the project brought many challenges to us from quick turnaround on the precasting of the segments to stringent water-cement ratios and testing requirements. Each and every load of concrete that was delivered to the Glass City Skyway project was tested before it was allowed to be placed and sets of cylinders made every 50 yards. Bill's expertise and knowledge made for a flawless multi-year project. He spent countless hours, days and nights lending assistance to the project and through his efforts strengthened his integrity within the Ohio DOT. Without the ideas and creativity presented to us by Bill we could not have had such a successful project." |
