Looked at new construction yesterday. The sill plate on exterior walls had 1/2 inch anchor bolts of the usual variety within 6 foot spans. Where sill plate boards were butt-joined together, shot-in anchors had been used about 4 inches from each end.
Are the shot-in’s sufficient, or should the sleeved ‘Red Head’ type anchors been used?

So right there we know that is not going to happen.
3000 psi concrete will take 14 days to achieve 75% strength. They usually have the house built by then. :mrgreen:
