3. Specifications 096519, Action 3.2.B.4 calls for moisture testing on the floor prior to installation. Does contractor need to include the cost of this testing in the bid?

Moisture testing is required because it is a standard requirement for manufacturer’s warranties. It is especially important to test old/existing slabs - older adhesives were much more tenacious than current ones and could stick to high-moisture slabs, encapsulating the moisture. Opening it up 40 years later could expose a wet slab that never completely dried. This is true for both slabs-on-grade and elevated slabs.
