If you put some row-bolts into the concrete too soon, when you tighten the bolt it will fracture the concrete. (Similar to putting a nail too close to the edge on a piece of wood. ) The bolts to hold the seats are only small so they will not have as long to wait for curing.
4 weeks is the maximum, about a week in decent weather will probably be enough.
By the time they have finished the concreting, the first lot should have cured enough to drill.
Building a wall on concrete is a different matter as the load is spread across the top in a downward force. Bolting exherts the stresses from inside to the outside forcing the concrete to split.
