For the construction (and home owner) folks - our cold room is under the front porch (concrete slab) and we never removed the wood framing/plywood the builder used when pouring the foundation and porch concrete slab. It's located on the ceiling of the cold room (under the porch concrete slab).
Is there a reason to keep this wood installed or was it only needed during the build/concrete pouring process? One small area got wet with a small leak from a pillar on the front porch which I'll be water sealing but the wood in the cold room needs to be addressed - not sure if I can just safely remove all the wood (2x4's and sub-floor plywood sheets) or if removal could cause longer term problems (ie. if the wood is actually a support structure at this point).
