1. In order to purchase an item from a qualified product list (QPL), prior to award what has to be obtained?


2. Which law is most applicable to contract for construction?
Davis Bacon Act
Sevice Contract Act
Walsh Healy Act
Competition in Contracting Act

Question 1: Look up QPL in the FAR manual. Check out Subchapter B, Part 9 and I believe you will find the answer to your question.

Question 2: The Davis Bacon Act applies to contracts for construction. You can find further information in the SAP manual, it will probably reference a FAR clause.

Hope the helps!
