New floor issues

New floor issues

New floor issues

(OP)
i am hoping to get some advice about an issue we have in a building we own. The floor was poured about 5 months ago and is approximately 5 or 6 inches thick. Has 2' rigid, insulation wire mesh and tubing for the radient heat. It is 24 X 32 and all poured at once. The building is built on a slope with one 32 ft side 9 inches above street level and the other 32 foot side has about 8 feet of foundation showing. The slope is about 8 ft in 24. Under the 32 foot side on the low side of the slope there is a mechanical room with 2 interior walls, a 16 ft one that goes from 1 corner to the center of the exposed 32 foot wall and another 8 ft one the goes towards the 32 ft side that is just above grade. This room is topped with 1/2 steel and the same pour that was done for the entire 24 X 32 floor. The steel rests on top of the interior and exterior wall that form the utility room. The 24 X 32 ft floor i belive is a 'floating floor' otherwise as it is not attached to the outside walls.
Now the problem. When they poured and finished the floor great effort was taked to keep it all level with a laser device. Now 5 months later the floor has a crack that starts at the point the mechanical room wall meets the 32 foot wall and extends on a diagonal the whole 24 ft across the room. The floor then slopes 1 5/8 from this crack towards the end of the 32 ft exposed wall. so the drop is 1 5/8 in 16 ft. at the street side of the same edge it is down 1 1/8. As a side note the building is not finished due to the late finish date and weather closing in here. It has no heat and no electricity as well.

Are there any standards and or procedures that describe what i need to do as an owner to get this corrected? If this description is not clear i can put up a drawing showing elevations and wall at a web site.
Any help would be appeciated.

RE: New floor issues

It just sounds like you have a consolidation of the underlying subgrade due to the fill.  Did you have a geotechnical engineer on this project?

The fix would have to be carefully worked out with a good knowledge of the soil conditions, types, compaction, etc as well as the physical construction elements of the building...i.e. we can't do the job from a website.

I would hire a structural and/or geotechnical engineer to study this in full.

RE: New floor issues

What local building code does your local inspector go by.  The code should state what is acceptable before a certificate of occupancy can be issued.
