TO: City Council
FROM: City Engineer
APPROVE CONSTRUCTION CHANGE ORDER NO. FIVE (5) TO G & M CONSTRUCTION
RECOMMENDATION:
That the City Council approve Construction Change Order No. Five (5) to G and M
Construction, for a decrease of<$6,697.99> forthe Underground Storage Tank Removal
and Replacement Project, City Project 95-17.
BACKGROUND:
On January 21, 1998, City Council of the City of Palm Springs awarded G and M
Construction the contract for the Underground Storage Tank Removals and Replacement
project.
This change order consists of the following work:
Schedule A - City Yard (Site No. 1)
Bid Item 3, Removal and Disposal of Contamination Material,decreased($8,550.00).This
bid item is lump sum. The decrease amount was calculated from the contractor's actual
invoice to remove the contaminated soil. Item F, Grade Level Fills,was added($2,570.60)
due to a design change for fuel delivery safety, per the City's consulting engineer.
Originally, fuel delivery to the aboveground tanks was to be from the top of the tanks,
using a stairway. By adding these grade level fills at the bottom of these tanks, liability for
injury would be reduced. Item G, Gas/Diesel Pump and Shelf, was added ($2,700.00) to
provide an emergency backup fuel system in the event there is a power failure. By having
these fuel pumps mounted on the aboveground fuel tanks, City personnel can continue
to fuel their vehicles. Item H, Relocate existing waterline, was added($402.80) because
the existing water line conflicted with the removal of the underground storage tank, per
plans. Items 1-1 through 1-5, were added ($2,240.00) per Riverside County HazMat
Agency's new testing requirements. Item J, Relay for the Gate Controller, was added
($221.40) to make the proposed new gate system integrate with the electrical system of
the existing gate. Item K, Twin Diesel Dispenser, was added ($1,920.00)to provide more
fuel dispensing for vehicles and equipment per the recommendation of the City's
consulting engineer and Fleet Operations Supervisor. The original contract Plans and
Specifications called out for single diesel dispenser. In the revised plan where the
aboveground storage tanks were installed in one central location, it was recommended by
the City's consulting engineer and Fleet Operations Supervisor to upgrade the single diesel
dispenser to a twin diesel dispenser. Credit was applied for the single diesel dispenser.

Item L, Break away Hose, was added ($298.80) due to an accident. A vehicle drove off
with the fuel dispenser still in the fuel tank of the vehicle. The fuel management system
was not on line when this occurred and it could not be determined who was the
responsible person who broke it. Item M, Relocate Air and Water Dispenser, was added
($922.80) per the recommendation of the Fleet Operations Supervisor to keep the air and
water dispenser away from the fuel island,allowing only vehicles to fuel. Item N was added
($ 404.39) per the recommendation of the Fleet Operations Supervisor to have a spare
circuit board for the gate controller to insure that if the circuit board fails, City personnel
can still have access in and out of the City Yard at all times.
Schedule B - Palm Springs Airport (Site No. 2)
Bid Item 3, Removal and Disposal of Contamination Material,was credited to the contract
($350.00) due to no contamination found during the removal of the under ground storage
tank.

($350.00)due to no contamination found during the removal of the under ground storage
tank.

($300.00)and installed a day tank for the existing generator to insure start-up in the event
of a power failure.
Schedule E- Wastewater Treatment Plant (Site No. 5)
Bid Item 3, Removal and Disposal of Contamination Material, was credited to the contract
($700.00) due to no contamination found during the removal of the under ground storage
tank.
Schedule F - Wastewater Treatment Plant Lift station at the Golf Course (Site No. 6)
Bid Item 3, Removal and Disposal of Contamination Material, was credited to the contract
($700.00)due to no contamination found during the removal of the under ground storage
tank.

Items B-1 through B-3, Overfill Alarm, was added ($722.80) per the requirements of the
Riverside County HazMat Agency to upgrade the existing underground fuel tank with an
overfill alarm system which will detect a spill, in the event of a fuel leak.
Credit($6,976.58)was applied in Change Order No. 1 because the cost to purchase the
aboveground storage tanks for Schedules A, B, C. E and F did not exceed estimated cost
Credit($1,425.00)for Item A,A/C Unit,was applied to Change Order No. 3. This item was
deleted because the temperature in the Lift Station would not exceed the recommended
operating temperature for the Veeter Root system.

C. REASON FOR CHANGE:
Increase to Contract (New Items):
Schedule A-City Yard (Site No. 1)
Item F was added due to a design change.This changewas recommended bythe City's consulting engineer,
Tait&Associates,for fuel delivery safety to the Aboveground Storage tanks. Originally,fuel delivery to the
aboveground tanks was to be from the top of these tanks, using a stairway. By adding these grade level fills
at the bottom of these tanks, liability for injury would be reduced.
Item G was added per the recommendation of the Fleet Operations Supervisor to have an emergency
backup fuel system in the event there is a power failure.By having these fuel pumps mounted on the above
ground fuel tanks, City personnel can continue to fuel their vehicles.
Item H was added because the existing water line to the City's car wash conflicted with the removal of the
existing underground storage tank.
Item 1-1 was added due to strictertesting requirements for MTBE per Riverside County HazMat Agency.This
test is to ensure there is no contamination in the ground that might lead into the ground water table.
Item 1-2 was added due to strictertesting requirement for Metals per Riverside County HazMat Agency.This
test is for waste oil leaks.
Item 1-3&4 was added due to stricter testing requirements for Benzine and Volatiles per Riverside County
HazMat Agency. These tests are for regulating excess vapor for unleaded fuel.
Item 1-5 was added into all existing underground storage tanks prior to removal to eliminate the oxygen in
the tanks. By doing this, it eliminates any chance of an explosion during removal. This was per Riverside
County HazMat Agency.
Item J was added to make the proposed new gate system integrate with the electrical system of the existing
gates.
Item K was added per the recommendation of the Fleet Operations Supervisor and the City's consulting
engineer, Tait & Associates. The original contract Plans and Specifications called out for a single diesel
dispenser. In the revised plan where the aboveground tanks were installed in one central location, it was
recommended by the Fleet Operations Supervisor and the City's consulting engineer, Tait&Associates,to
upgrade the single diesel dispenser to a twin diesel dispenser.The contractor credited the City for the single
nozzle dispenser.

C. REASON FOR CHANGE:
Increase to Contract(New Items):

Item M was added per the recommendation of the Fleet Operations Supervisor to keep the air and water

equipment that are only using the air and water dispenser.
Item N was added per the request of the Fleet Operations Supervisor who requested to have a spare circuit
board for the gate controller to insure that if the circuit board fails, City personnel can still have access in and
out of the City Yard at all times.

day tank would work better to start-up the generator in the event of a power failure.

upgrade the existing underground fuel tank with a overfill alarm system, which will detect spillage, in the event
