Today’s architectural interns don’t have it easy. Compared to when I entered the profession, they have to know a lot more stuff—and a lot of different kinds of stuff. For one thing, they have to learn 40 years of architectural history that I didn’t. And they have to know about accessible design, sustainable design, and resilient design—all of which we should have been paying attention to 40 years ago but mostly weren’t. And then there’s the technology. Just the number of software programs that interns need to master is daunting. With all this additional knowledge they need, it’s understandable that a few things that used to be considered basic skills might fall into a crack in the Sidewalk of Experience. Things such as dimensioning.
