RE: Administrative Change Order No. # 1
Reservoir No. 2 - Test Production & Monitoring Well Project
RECOMMENDED ACTION: Approve Administrative Change Order No. #1 to Thompson Well &
Pump, Inc., of Deland, FL, for the "Reservoir No. 2 - Test Production & Monitoring Well Project" (06-
0055-UT), increasing the contract by $68,420.50 for a new contract total of $858,946.81.
BACKGROUND: This is for the purpose of decreasing contract of unused items; increase contract
with overrun items; increase contract with additional items; and increase the existing contract for an

1. Increases do not exceed 10% of the Council approved amount on a cumulative basis.
2. Change does not change the scope of the project.
3. Price increases do not require additional appropriation to the project.
4. Contract price decreases may be approved without limitation.
5. Completion date is not extended more than 60 days.
