I'm semi-retired now, but was a landscape and irrigation contractor for quite a few years, so we dealt with utilities on a regular basis - both underground and above.

Some of my accounts were 6 story condominiums.....and along with those a need for utilities. In my observations of the amount of coordination needed when they ran these - different kinds from different companies - and subsequent servicing needs for the future - I thought of a concept as follows:

Install a culvert pipe underground that runs from the utility source at the street to the structure. Have it come in underneath the building and into the parking garage. The pipe would be large enough for a human to stand up inside. In that pipe....run all the utilities.....fastened to the vertical walls of the pipe. This would keep it away from any excavation harm and also make it totally accessible for troubleshooting or service needs.

No need to send a locator out to flag the place whenever they need that. Just go into the pipe and there they are. Cost of installing pipe is shared by all involved. Probably never happen but it's the same idea of using conduit to pull electric through - only on a grander scale...
