Install Practice.

It lurks below

A two-lane optical-turnstile install in a downtown high-rise stopped before the first hole when we found the floor had already been x-rayed and marked. The slab was post-tensioned — and the people telling us to drill didn't know what that meant. The story is about the rule that kept us off that floor, and what's actually stored in the concrete under your boots.

You want to be responsible?

Four installs across as many years where the right answer was no — a CRT we shouldn't have lifted by hand, a hospital wall spec that ignored physics, a basement wall that moved when I touched it, and a brand-new bank office that wasn't a room yet. The thread running through all of them is the same question.
