VERNON, IOWA — The Tilt-Up Concrete Association (TCA) — a nonprofit international organization that serves to expand and improve the use of Tilt-Up as the preferred building system — has announced the election of new board members and the slate of officers for the 2013 year. Glenn Doncaster, president of Citadel Contractors, Inc. (Apex, NC) will continue to serve as president of the TCA Board of Directors. Doncaster specializes in taking projects intended for traditional masonry and transforming them using tilt-up technology. He has been a member of the construction industry for several decades and a TCA Board of Directors member since 2004. Other officers serving the Board for 2013 are: • President elect: Kimberly Corwin of A.H. Harris & Sons (Newington, CN) • Secretary: James Williams, P.E., C.E., S.E., AIA of ae urbia and J.M.

• Mike Denson of Innovative Brick Systems, LLC. (Broomfield, CO) • Frank Adames of Contratistas Civiles y Mecanicos (CCM) (Santo Domingo, Dominican Republic) • Jeffrey Brown, AIA, of Powers Brown Architecture (Houston, Texas) • Andrew S. McPherson of Seretta Construction (Apopka, FlL; Charlotte, NC or Austin, Texas) • Tom Stecker of Thermomass (Boone, Iowa) • Shannon D. Stucker of AML, Inc. (Floyds Knobs, IN) • James Williams, P.E., C.E., S.E., AIA of ae urbia and J.M. Williams and Associates, Inc. (Salt Lake City, Utah) Ex-officio members of the Board from related associations are: • Lionel Lemay, director of Applied Engineering for the National Ready Mix Concrete Association • Douglas Sordyl, managing director for Industry Affairs of the American Concrete Institute • Tony Johnson, regional manager for the Concrete Reinforcing Steel Institute • Larry Novak, director of Engineered Buildings for the Portland Cement Association Elected to three year terms to the Board for the first time are: • Scott Collins, P.E., chief engineer for Meadow Burke, selected by the Global Associates Council

• Matthew Bell, P.E., Structural/Field Engineer with LJB, Inc.’s Facilities Division (elected by the membership by mail ballot) Collins has been a strong leader on the TCA’s technical committee for the past several years as well as a member of ACI 551 — Tilt-Up Concrete. Most recently, he coauthored the TCA’s new bracing guidelines and he has contributed to multiple articles for TCA over the years. He was responsible for the lifting and bracing design of the Korean War Veterans Memorial that was dedicated at the 2010 TCA Convention in Kansas City. Collins is also serving on the 2014 TCA Convention (San Francisco) host committee. “I’ve been on the receiving end of using the benefits from TCA practically my entire career, and I welcome the opportunity to serve on the board. Hopefully my background in lifting and bracing on the engineering side can bring a new perspective to the board,” said Collins. Bell provides complete building shell design of low rise commercial structures, including a specialty in the design of tilt-up construction. As lead field engineer supporting the LJB’s CON/STEEL Alliance, Bell is also responsible for training contractors in the means and methods of tilt-up construction. He facilitates both classroom training and onsite in the field training.

Further, he is currently serving as the chairperson for the subcommittee overseeing the Tilt-Up Engineering Manual development. As chairperson, he is responsible for gaining consensus on the Table of Contents from the subcommittee members; managing the delivery of the Chapters from the co-authors; coordinating the review activities of the subcommittee and communicating progress reports with the chairperson of the Technical Committee and with the TCA Board of Directors “It is a great privilege to be selected for the TCA Board of Directors and to represent the tilt-up industry as a whole. I hope to bring a unique perspective to the board by utilizing my experience at LJB as a project manager, structural engineer and lead field engineer, supporting the CON/STEEL AllianceTM with hands-on tilt-up construction training,” said Bell. TCA was founded in 1986 to improve the quality and acceptance of site cast Tilt-Up construction, a method in which concrete wall panels are cast onsite and tilted into place. Tilt-Up construction is one of the fastest growing industries in the U.S., combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650-million-square-feet, are constructed each year using this construction method. For more information, visit or contact TCA at 319895-6911.

Martin from 19 in any of the countries in which the firm does business. Customers will benefit from regional engineering, manufacturing and service in virtually any location. “There are many suppliers who provide off the shelf solutions, and we will continue offering conventional vibrators in a wide range of sizes and force outputs,” Nogaj continued. “But for the builders of next generation equipment, we can now deliver design options that engineers have never had before. Instead of being limited to an off the shelf vibrator, manufacturers can specify the exact sizes and parameters they need to suit new and emerging designs.” Nogaj said that the designs are likely to find utility in high frequency vibratory screens, sizing equipment, dewatering operations and other vibratory equipment for the oil and gas industries, as well as processing of coal, iron ore, gold and other elements, silica sand, pharmaceuticals and even food applications. While traditional designs will remain a cornerstone of Martin Engi-

neering’s family of vibration products, the company is now able to custom engineer the size and shape of the drives, torque curves, weight and many other features, in both electrical and mechanical units. “This will allow OEMs to build equipment that hasn’t been available in the past,” Nogaj continued. “Rather than being handcuffed into using the stock designs that are on the market now, they can order the exact vibrator properties, profile and output that they need.” An important component in the decision to offer custom engineered vibration is Martin Engineering’s extensive new R&D capabilities in the CFI. For example, the firm has recently added four massive, spring mounted 10,000 pound test blocks specifically for development and trial of new vibrator designs. “This kind of capability is intended to serve the OEM who has vibration needs that are presently unmet,” said Global Vibration Development Manager Brad Pronschinske. “It will be a huge competitive advan-

tage for manufacturers trying to develop new products, giving them a design freedom that wasn’t possible before.” Martin Engineering’s new capabilities also include sophisticated dynamometer testing that allows the company to map the shape and values of an electric motor’s torque curve. “The dyno testing helps us analyze existing designs, but it also means that customers can come to us to obtain a specific torque curve,” continued Pronschinske. “That can be an extremely valuable asset for new product development, and until now it’s been a service that has been nearly impossible to find without investing huge amounts of money.” Further supporting Martin Engineering’s commitment to the custom engineering concept is an endurance testing station located outside the CFI, where engineers can evaluate new vibratory drives and screen designs on any of five different shakers. A similar station at the company’s China facility also features two shakers. “The outdoor test stations are

intended to duplicate tough real-world operating conditions,” Pronschinske added. “The setup at CFI has one shaker design with a four pole drive unit that can develop as much as 10 Gs of force, helping us to engineer the highest quality, longest lasting vibrators in the world.” Martin Engineering will offer an extensive range of designs and features for specific applications, including explosion proof models, vertical shaft units, flange mounted designs and even low profile vibrators that can be incorporated as part of a support structure. “This capability allows us to take a huge leap beyond the conventional four footed designs that dominate the market today,” Pronschinske said. Martin Engineering vibrators deliver the highest force to weight ratio of any electric vibrator manufacturer. Founded in 1944, Martin Engineering is the world leader in making bulk materials handling cleaner, safer and more productive. The firm is headquartered in Neponset, IL, offering

manufacturing, sales and service from factory owned business units in Brazil, China, France, Germany, Indonesia, Mexico, South Africa, Turkey, India and the UK, and under exclusive license with ESS Australia. For more informa-
