I don't know what the footage is. As you can see this continued on to the chiller rooms, cooling tower yard and boiler room. This work was done in two major phases this being the first. We have a backhoe sub that does allot of electrical underground work. They did s good job on the back fill. I am aways real adamant they don't knock the risers out of plumb. There is nothing worse than spending all this time precisely positioning them to have the backhoe tweak them with a sheep's foot or a whacker. If I remember right this portion took 120 CU yards of 2 sack concrete to cover. They spent two more days backfilling to grade.
