RECOMMENDED ACTION:

ENG MODULAR PROJECT TO BE RE-BID
Adopt Resolution No. 7773 making the finding that the Public
Contract Code does not need to be complied with and authorize '
Concepts of San Diego and Scibila & Sons of Escondido or instri
the City Manager to further investigate the leasing of needed
space and report back to the City Council with a recommendatior
or order the modular project to be re-bid.
City Manager to enter into contract with Modular Building
ITEM EXPLANATION:
On August 14, 1984, the City Council authorized advertising foi
the City Hall Modular construction. The Bid opening was
scheduled for September 12. No bids were received.
Per the Public Contract Code 20166, "If no bids are received, 1
Legislative Body may have the project done without further
complying with this Chapter .I1
Therefore, it is recommended that the City Council make the
finding that the Standard Bid Procedure was followed and ROW tI-
Public Contract Code governing bid procedures no longer need tc
be followed.
Staff has investigated alternative means of completing the
construction. Staff has contacted contractors and obtained
separate bids for construction of the modulars and parking lot.
The lowest of three bids for the modular building was by Modul:
Building Concepts of San Diego in the amount of $102,766. The
lowest bid for the parking lot construction was by Scibilia &
Sons of Escondido in the amount of $14,700. It is estimated tk
an additional amount of $3,000 will be needed for soil
compaction.
The total estimate therefore, is:
$102,766 Modular Building
Parking Lot 14,700
Soil Compaction 3,000
10% Contingency 12,047
TOTAL: $1 32,513
An alternative for the City is to lease space in a private offi
building. It is estimated that such space can be leased for three years at about the same cost as constructing the modular.

More accurate cost figures for leasing will be presented to the
Council at its meeting.
A final alternative is for the Council to order the project to I
re-bid, either as before, or separating out the modular buildin!
and the parking lot. About three weeks of additional time woulc
be needed for such process.
FISCAL IMPACT:
The City Council has already appropriated $145,000 (Acct. 81-18-10-3165) for this project. Thus the cost of any
alternative is provided for.
