Perhaps not with building properties, but very small errors can cause catastrophic failure.

One of the most famous ones would be the Hyatt Regency collapse, where a contractor accidentally doubled the load on a walkway because he used two shorter beans attached to the top and bottom of a slab, rather than a longer beam that passed through it.

In electrical engineering, it's very common to have ICs that function as a microcontroller at 5.5V, and an egg cooker at 5.6V.

Microsoft lost hundreds of millions of dollars repairing the original Xbox 360 because the solder on the GPU cracked under thermal stress.

It's definitely not to the same extreme as software, but tiny errors do have catastrophic consequences in physical systems too.
