This is a new foundation job. What you are looking at is a footing with 4 rows of rebar with 12 inch anchor bolts and plywood forms. The next step would be to pour the concrete into the footings.
New 4x6 Beams, new 4x4 posts, and newly installed precast concrete piers.
Structural 1 Plywood with Ventilated Holes, and earthquake anchor side plates for a positive connection to the foundation.
