How do you hide the pipe between point A and point B?

Have you ever seen one of these statues where it appears that water is pouring from a faucet without a supply pipe?



Unfortunately on our projects to get water from point A to point B we need a pipe (and a wall to hide it in).  Thanks to BIM we were able to identify an area on our Icon project where plumbing was designed to run down to a sink where there wasn’t a wall to hide it in.  Finding this issue early now gives us the option to look at other walls and ways to get the water supply to the sink without impacting the cost and schedule of the project.
