Outdoor spigot issue [View all]

One of my outdoor spigots is next to the area that I had a concrete patio poured a couple of days ago. The worker even asked me where to turn it off. He said he just capped the sprinklers before pouring the concrete, but now I have no water coming out of the spigot. Did he screw something up? How can I get it back on? Would capping a sprinkler nearby stop the water? Help!
