11. Q: Per Section 10.1 Experience -Submission Requirements, “The offeror shall submit up to three

(3) examples of substation transformer removal and installation, low voltage power circuit breaker retro fill and low voltage switchgear bus re-bracing projects which best illustrate the experience of the contractor on projects of similar function and scope.” However in section 11.1 Past Performance - Submission Requirements, ” The Offeror shall submit at a minimum description of five (5) supply and installation contracts for substation transformer removal and installation, low voltage power circuit breaker retro fill and low voltage switchgear bus re-bracing projects performed as a prime contractor in recent years.”

Since we are submitting three (3) project per section 10.1, shouldn’t the same projects be provided for section 11.1?

If this is the case are three (3) Past Performance Information (i.e. PPQ’s) acceptable for this section?

A: Experience is stating that you’ve done this work, past performance is relevancy to the proposed work and how well you’ve done it. They are two different things, however, the 3 projects you submit for Experience can also be used for Past Performance.
