How can you really, really seal any gap between your pipe and the rest of the wall that just had a hole put in it to accommodate the pipe’s path? That’s a question we haven’t asked in these pages before. Learn about the available technology, bolt/nut combinations, and more to maintain a safe long-term relationship between these elements of your building systems and your building.

Follow one firm’s path from committing to BIM to climbing a learning curve in using it to serve clients, and even on to taking an unusual step to fill what it sees as a need in the market.

In the big picture, good enough isn’t good enough.
