Route 1 through North Attleborough was the old Boston-to-Providence post road, and it still carries the town's business — plazas, offices, lots that have to be open the moment the doors unlock. Case Facilities Management Solutions plows and clears those properties, working the hours after a storm stops and before anyone has touched the pavement. Lots get pushed toward the same corners every time, so banks stay out of the parking and out of the sight lines. Walkways and entries are shoveled and treated, with de-icer down ahead of the overnight refreeze. The measure of it is a place that opens at its usual hour, as though the night had been an ordinary one.
