Pump House Foundation on Rock
Pump House Foundation on Rock
(OP)
We are designing a new booster transfer station and a new precast concrete pump house. How do you build a concrete foundation on top of rock? Do you drill and set rebar into the rock, then make your concrete forms and pour the concrete? Or can you simply make the forms. The weight of the pump house and pump station is approximately 45,000 lbs. over a 11'x14' footprint.

However, if your site is relatively flat, I guess you would have to ask yourself where the structure could migrate to in a seismic event. That being said, being a pumphouse, how much "walking" could your piping system tolerate without rupturing and system failure?

msquared48: I think that the tolerance could have a large range dependent upon how I design the suction/discharge pipe connections to the pump house. It could be designed rigid or flexible, I would suppose; I vote flexible - to maximize pipe "walking" and minimize failure.
