ITEM TITLE: Resolution ,/{ ,,J Approving Change Order No. 2, removal
of underground fuel tanks at various locations in the City and
authorizing the City Engineer tLcute
SUBMITTED BY: Director of Public Works/City Engineer
REVIEWED BY: City Manager < (4/5ths Vote: Yes No X )
On April 10, 1987, the City Council by Resolution No. 12940 awarded a contract
to American Processing Co. , Inc. for the removal of underground tanks at
various locations in the City.
The specifications for the project state "If a small amount of contaminated
material is found, the City may have it removed and disposed of as extra
work. " This provision needs to be applied now as contaminated soil has been
excavated at four of the five sites amounting to about 80 cubic yards.
RECOMMENDATION: That Council adopt the resolution approving the change
order and authorizing the City Engineer to execute it on behalf of the City.
BOARDS/COMMISSIONS RECOMMENDATION: Not applicable.
DISCUSSION:
American Processing Co. , Inc. has removed the eight (8) underground fuel tanks
at five (5) locations in the City in accordance with the contract for this
project.
Unfortunately, four of the eight tanks had leaked and contaminated soil was
found. The contaminated soil was stored and covered with plastic flexible
material at the following locations:
a) Fire Station No. 1 c) Police Station
b) Fire Station No. 2 d) Public Works Yard
The total contaminated soil volume is estimated to be about 80 cubic yards.
Based on an assumed average unit weight of 1 .34 tons per cubic yard, the
material is estimated to weigh about 107 tons. The contract specifications
provided for the removal of the soil via execution of a contract change order
covering this extra work.
Accordingly, we received a proposal from the contractor to remove and dispose
of the contaminated material at a cost of $186.57 per ton. Based on this per
ton price, we estimate this change order to be between $20,000 and $25,000.

Meeting Date 6/9/87
To ascertain the contract average soil weight, a one (1 ) cubic yard random
sample of soil will be weighed. In addition, the contractor will be required
to submit weight tickets to verify tare weights with the final billing.
Although this change order will increase the contract amount to between
$45,175.00 and $50,175, there are sufficient funds to cover the increase. On
November 11 , 1986, Council appropriated $94,000 for the removal of the eight
tanks and the installation of two new 1 ,000 gallon tanks at Fire Station No.
2. Staff prepared a report which discussed how the $94,000 amount was to be
allocated to accomplish the project. In essence, we estimated the removal
phase of the project to cost about $54,000 and the new tank installation phase
about $40,000. Thus, even with the increase, we are still within the budgeted
amount allocated for the removal of the tanks. This is in part attributable
to the great cooperation we have obtained from both the contractor and the
County Hazardous Material Management Unit Inspector.
FISCAL IMPACT: This change order will increase the contract amount between
$20,000 and $25,000. However, there are sufficient funds available in the
fund balance for this project (600-6000-GF37) to cover the increase.
