Need a structural engineer

[Myka]

Talk to someone in the contractors department at a Home Hardware or Home Depot. They should be able to give you a name.

Side note...as long as the house is properly built, there shouldn't be a problem with 180lbs/sqft. As long as you go perpendicular across the floor joists, or the concrete is thick enough.

PS Didn't you post this same question a couple months back? Didn't we already disagree about it?
