Water Line Construction Along North Highland Ave.

Hello Neighbors, We noticed during the last couple of days, construction crews were installing a water/sewer pipe line along N. Highland Ave. between Hampton & Bryant St. We were surprised that we were not contacted by the City of Pittsburgh about their plans, and the subsequent water shut-off. We didn't see any mention of the planned work on the Highland Park website, and curious if others were unaware as well. Also, we would like to know if the construction company/City of Pittsburgh will cover any repairs if damage occurs to the sidewalk, curb, or the affected property. Any information will be greatly appreciated. Thanks, George
