Construction is all about operations management. You have to get it done ASAP because every day costs money in permits and equipment leasing, if materials or equipment aren't on site then the site goes idle, and storage space is often limited.

If you are going to involve robots, you would have them operate to a central plan, not invent their own. This means temporarily fencing off nominally exclusive spaces would be relatively straightforward.

Incidentally, I have an acquaintance who is heavily (tens of millions USD) invested in scaling a new business in the custom building domain. The concept is that a site is surveyed, a design set, then they pre-fab the building structure, ship it (internationally) flatpack in shipping containers, and - though it's manual for now - eventually assemble with robotics, an area in which they have been aggressively inventing and acquiring patents. I haven't asked but I very much doubt they are focusing on inter-agent motion planning as a priority.

It's complex enough, and that's essentially an avoidable problem.

Sure, they would of course need coordination just would not need to be told about every movement and addition. Think agile vs. waterfall.
