I am building a rather large prison all at once, and have run into a problem. I built cell blocks en masse, and then built the utilities. This is causing this to happen:
The builders cannot reach the pipe to build it because of walls, and end up deleting the job.
While I could remove a wall to let the Workers in to every pipe, that might take 30 minutes+ and would be expensive. Is there any way to force a Worker to build on these corners?
