ITEM TITLE:
RECOM.1ENDATION: That Counci 1:
1. Authorize the expenditure of $84,090.00 from the Lorna Verde
Solar-Contract Construction fund.
2.

BOARD/COM.1ISSION RECOMMENDATION: Not applicable.
DISCUSSION:
The City Council by Resolution 9820 approved an agreement with Mitchell-
Webb Associates, Inc. for the preparation of plans and specifications
for the construction of a solar heating system at Loma Verde Park.
Final construction plans were prepared using glazed collectors. This
system will provide 21% of the current energy needs for heating the pool
water and 6% of the current energy needs for heating the water for the
showers. This system provides 13% of the total current energy needs for
the Loma Verde complex provided by natural gas.
Based upon the assumption that the price paid for natural gas will
increase at an annual rate of 15% for the next 5 years and 10%
thereafter, the cost of energy per unit from the solar system will equal
that of natural gas by 1986. Every year thereafter, the solar system is
expected to provide energy at a lesser cost than natural gas.
The plans were recently completed and staff advertised for bids for the
construction of the solar heating system. Bids were received from two
contractors as follows:
1. Parnell & Leonard, Inc. - San Diego
2. Specialty Systems, Inc. - Spring Valley
$77,861.00
$124,900.00
The low bid submitted by Parnell & Leonard,. Inc. is below the Engineer's
estimate of $88,589.85 ~~ $10,728.85 ~r 12.1%. .
