The 5" slab reinforcing had #4 bars at 18" on-center each way. The thickened slab exterior wall footings had (3) continuous #5 bars, with #5 transverse bars at 15" on-center. The interior wall footing had (4) continuous #5 bars, with #5 transverse bars at 12" on-center. The exterior wall verts were #5 bars at 12" on-center inside face and 15" on-center outside face. Interior and knee walls had #5 verts at 12" on-center. All reinforcing was found to be of correct grade, size, location, spacing, lap, clearance and secure, and was in-compliance with approved plans and specs. 2) Concrete:: MTC witnessed the placement of 100 yards of Miles concrete mix #18400F, 3000 psi minimum required strength. The concrete was placed by pump and mechanically vibrated for consolidation. One set of five 4x8 cylinders was cast for compressive strength testing. To the best of MTC inspector's knowledge, the above-described work was performed in general accordance with project specifications and approved plans.
