Double digging

I could not believe it when on Monday morning I observed Scottish Water digging up Kirk Brae in Liberton, a section of road which has just been completely resurfaced at considerable expense and great inconvenience to road users, as the road was closed for many weeks while the work was done.

Could Scottish Water not have done its work before the resurfacing work was started?

Why do the different departments not speak to each other?
