Do find the process entertaining.
First had the equipment taking off the soil, they go away, another crew comes back and contours they go. The hoes come in they do the sewer lines, backfill and go. Oh, lets dig it up again for the water. These guys for the side walk, then after they leave someone else to back to pave. If as the other areas, still will have 3 more separate crews (gas, power, comm). Not finished yet, need to cut the new pavement for the manholes, wait no fire hydrants or street lights. Can't forget to get the concrete guys back to redo the sidewalks at the corners for ramps. Once the houses start, more digging to bring the utilities from the curb.
