48” on center post and beam. 1 1/8 plywood. Late 70’s house.

Wife wants engineered hardwood. Currently carpet and linoleum.

Should I add 4 foot blocking every 16 or 24 inches? Or just cry? What would you do. This is post and beam. Beams are 4x6. There are no joists.

Thanks,
Bobby

This type of framing is suitable for any type of hardwood floor, going any direction. The floor will need to be checked for flatness. High spots sanded down and low areas built up.
Full sheets of plywood span two beams.

Not what I was expecting, as much as I would like to do nothing please take a look at this chat I found about a similar if not exactly the same subfloor. https://www.diychatroom.com/threads/hou ... sts.18294/

Some people think a zero deflection floor is best. I appreciate some deflection since the floor is being used for walking, as it is more comfortable. Tile floors on a slab can become uncomfortable to some people because there is no deflection..
I have recommended adding extra framing if the span is over 48 inch centers, in concentrate use, like a kitchen, or if the plywood does not touch 3 beams. A half sheet will not resist deflection as much. Adding 2X6 joists would help to get the floor flat if there is a substantial dip.
Adding half inch plywood will not increase resistance to deflection unless it is a full spread adhesive installation, in my opinion.
If you would like to get the full value from another hardwood floor over the top of the existing sub-floor, a full spred of adhesive will stiffen it.
