How should a contractor respond to a specification requirement that “the nominal dry film thickness of the coating shall be 3 mils?”

From George Musterer of Hecate Painting & Sandblasting on July 2, 2014:
Three mils is a defined single thickness that would be impossible to achieve. The best answer is to request clarification from the consultant. They need to provide a suitable range (i.e., 2-4 mils) recommended by the manufacturer. Nominal means "in name only" such as a 2x4, which is actually 1 1/2" x 3 1/2". It is hard to determine what the intent was when using the term "nominal." Using a range is the best way to define coating thickness.

From david cuthbertson of savcor on June 20, 2014:
If the coating is IOZ, no problem.

From James Albertoni of CA Department of Water Resources on May 28, 2014:
Generally, nominal is used in place of average; therefore, the minimum and maximum allowable thickness would be based on the referenced standard, such as SSPC-PA 2. However, as Russell pointed out, if it is not defined, then request clarification through the RFI process.

From Russell Draper of Group 10 Engineering on May 13, 2014:
If the meaning of the word is not defined in the specification or contract, the contractor should request a clarification.
