AMENDMENT 0001

QUESTIONS & ANSWERS

1. QUESTION: Question: While the subject line and Scope of Services state, "Inspection", #4 details that there is to be an in-service cleanout. Are all tanks to be cleaned and inspected?

ANSWER: Yes, all tanks are to be cleaned and inspected. Please note, this Amendment #01 includes a revised Scope of Services and Price Schedule that removes the Chapin Mesa Tank - 100,000 gallon (Lat:

2. QUESTION: The general project description says that three (3) ground tanks and one (1) clear well were in scope. However, the RFQ listed four (4) ground tanks, one (1) clear well and two (2) raw water vaults. Also, on page 6 of the RFQ, the price schedule lists only a quantity of one (1) raw water vaults but the plural "s" of vaults would indicate two (2) or more.

ANSWER: Total of three (3) underground tanks. Clearwell is separate and the Raw Water Vaults are side by side in the same location sharing a wall.
