Re: Alternate Cold Joint Location

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bill, I would have 2 (potential) concerns:

1.  The finish at each side of the vertical construction joint may not match, especially since foundation construction tolerances don't often match floor construction/finishing tolerances.

2.  Detail B seems to provide limited resistance to vertical movement of the slab relative to the foundation, either downward or upward. 

The significance of these may depend on the use.

Dear colleagues,
A contractor has requested an alternate cold joint location. In the sketch found in the link below:
Alternate A is the method shown on the approved plans.
Alternate B is what the contractor wants to do.
The dowels match the slab bars.
Should I have a concern about the request?
