FOCUS INSPIRING CREATIVITY PCL’s desire to tackle complex projects encourages creativity and innovation as it meets evolving challenges of risk management, project delivery methods, and others by Craig A. Shutt PCL has advanced considerably since its founding 110 years ago in Saskatchewan, Canada, but one aspect hasn’t changed: Its ambition and desire to take on new challenges and work on the most complex bridge projects possible. The philosophy leads most frequently to building concrete designs as the firm handles an evolving array of challenges. “We enjoy working on complex bridges, and we’re not ashamed to say that we think we’re pretty good at building them,” says Jim Schneiderman, area manager for the firm’s Mid-Atlantic office in Raleigh, N.C. “PCL has a very strong bench of technical expertise, so anything that is challeÿÿÿ Adds Ankur Talwar, district manager for the Transportation Infrastructure Group based in Seattle, “Our goal is to be a value-added company. That usually leads us to more sophisticated delivery methods that allow more contractor involvement and engagement.” Schneiderman agrees. “Just being the low-bidder on a design-bid-build project isn’t a good win strategy for us. We prefer more involvement in the design process so we can help innovate and create an efficient project.” Bridge owners are seeing the benefits of leveraging those talents, as more are using alternative delivery methods, including design-build, construction manager/general contractor (CM/GC), and public-private partnerships (P3). “CM/GC fits our culture very well,” says Gayle Grady, district manager in the Tampa, Fla., office. “It gives us the opportunity to plan and implement construction means and methods along with delivery of the project. The owner has the opportunity to gain knowledge of the project’s design and how it will be delivered to them. It absolutely aids constructability.” Grady currently is working on her third CM/GC project, in Hartford, Vt., in which the existing north and south bridges carrying Interstate 91 (I-91) over U.S. Route 5 are being replaced using the lateral slide technique. New bridge abutments will be built while traffic continues, then the new bridges will be slid into place over two weekends. The project will be completed in June 2016. “These ABC [accelerated bridge construction] techniques are a good example of the innovation and adaptability that our clients seek,” she says. She also is working on the I-91 Brattleboro Bridge improvement project, which involves replacing two steel-truss bridges over the West River in Brattleboro, Vt., with a single cast-inplace concrete segmental bridge built using balanced-cantilever construction with form travelers. The bridge, created under the design-build format, will have a design life of 100 years and feature a 515-ft-long main span and 263- and 258-ft-long back spans. It will be built on 66-in.-diameter drilled-shaft foundations with aesthetic piers replicating Vermont’s iconic stone. “Our goal is to develop an iconic, gateway structure that provides an aesthetically pleasing, high-quality, environmentally sensitive, sustainable bridge.”€ “We are capable of working in any format the client is most comfortable with,” says Talwar. “These new approaches require higher staffing requirements upfront, but the end result is a reduction in costs and faster scheduling. Those usually are the owner’s main drivers.”ð©1
