F O C U S Focus on new concepts being used around the world keeps IBT growing in its 10th year International Bridge Technologies (IBT), celebrating its 10th anniversary of operation this year, embodies its name in virtually every project it undertakes. Its record of accomplishments around the globe already has been notable, and it expects its approach to innovation and international work will continue. Some of that work will come via advancements in concrete material and construction techniques, which IBT uses in a high percentage of its projects. "We've found there's a lot of value in trying to be ahead of the curve of creating new ideas for bridge construction," says Chris Hall, one of IBT's three founders. "We've had considerable success in our 10 years and have seen a lot of growth. We believe it derives from our willingness to be open to new solutions. Everyone wants to be innovative, of course, but we've had many opportunities, especially through the design-build process, to work outside the box with contractors and not be told 'no.' " The company's expertise with concrete construction techniques has a strong foundation. IBT was founded in San Diego by Daniel Tassin, Michael Smart, and Hall. The three gained experience at Jean Muller International Inc. (JMI), whose founder developed the technique of precast concrete segmental bridge construction. "His focus was always on marrying new construction techniques to efficient designs," Hall says. Muller, in turn, studied under Eugene Freyssinet, the inventor of modern prestressing techniques. "Our historical relationship with design- build contractors has really created the framework for practical innovation." says Hall. "Being close to construction lets us understand the issues that need to be addressed in our designs. More important are the relationships built over time. Through successful collaborations, we have established the trust that allows our concepts to advance into practice." Five International Offices In just one decade, the company has grown to encompass employees working from five offices around the world: San Diego, USA; Bangkok, T h a i l a n d ; M e x i c o C i t y, M e x i c o ; Vancouver, Canada; and Abu Dhabi, United Arab Emirates. From those locations, the company has designed projects in Canada, Puerto Rico, India, Abu Dhabi, Mexico, Australia, Jamaica, and the United States. INTERNATIONAL BRIDGE TECHNOLOGIES Lives up to its Name by Craig A. Shutt The 2890-ft-long Second Vivekananda Crossing in Calcutta, India, uses the extradose concept, which features precast concrete box girders that work with low-angle stay cables. It provides a new and developing concept for medium-span bridges with clearance issues.
