QUESTIONS_AND_ANSWERS.docx

Here are the responses to the questions received from the bidders on the Big Spring Replace Backflow Preventers. The question that was asked is listed first, and then the BOP’s answer is in bold. I have also identified whether it is just a mere clarification or an amendment item (something that has changed, been added or deleted). If you require further clarification, please advise John Holleman.

It is worth noting that the serial numbers listed above are “as read by the previous inspector” and FCI Big Spring does not guarantee their accuracy. It is the Contractors, responsibility to field verify existing conditions prior to ordering any materials. Clarification
