fabricator when he goes to do fit-up.” Braun said “getting off on the right foot” was important
for the project. Te metalcaster didn’t want to get far along and find out the finished component did not match expecta- tions. Representatives of different parts of the project’s chain were invited to see the castings and provide feedback. “Getting that first article done and understanding that
you’ve laid the part out properly, and have machined it within the plane is why we do the 3-D overlay,” Braun said. “Or we’ll lay it out and then send them the file, and they will then put it in the envelope to make sure that it complies. Once you’ve got that locked down, then you can be sure your subsequent parts are going to yield the precision that’s required in the dimensional component.” Other manufacturing processes theoretically could have been used to create this component. Casting, however, brought many distinct advantages. Beyond the aesthetics, it holds an ability to handle a bigger range of challenges, not to mention the absence of weld joints, leading to more capability to handle stresses. “One of the advantages is the ability to make shapes that
are aesthetically pleasing to an architect,” Braun said. “If you combine those with the various grades and strengths that steel offers in addition to its weldability, it really gives you a number of options that allow you to cast shapes that are extraordinarily difficult or almost impossible to fabricate.” Projects like these have another advantage: it can help a firm
like Bradken continue to make its mark in the architectural world. Bradken is a member of the American Institute of Steel Construction, and Braun and de Oliviera have given co-talks on the use of steel castings and the benefits they can bring. “We can say not only do we believe this, we’re actually doing it and we’ve done it in this example, this example and this example,” Braun said. “You don’t want somebody who’s never done one before that says ‘Yeah, I think we can cast that shape,’ because it’s about understanding what you’re casting, why you’re casting and what’s important on that casting.”
