Construction Update #20

The sides of the building by the elevator needs compacted fill to support the foundation and slab for the middle level. Slabs need 85% compaction. Foundations need 95%. Yeah, whatever. The problem we faced was # 1 being unable to get any heavy equipment bact there and #2 not being able to compact against a concrete wall until after the next floor is poured.

Kind a chicken and egg thing. Cant pour the floor until ground gets raised and compacted. Can’t compact against the wall until the floor gets poured.  So, we are going with CDF, a pourable structural fill that goes up in 2’ lifts with no lateral force after each day.

Judging by Eric’s pant leg, we must have poured slightly over two feet!

Adding magic to the mystery, Golden Air converts 8 CY of CDF to 12 CY with only one quart of the potion. I say put in the whole gallon and be done with it!
