TRAFFIC SIGNAI INSTALLATIONS AND MODIFICATIONS - BID AWARD
DEPARTMENT: Public
BACKGROUND
On December 11, 1990, Council authorized the advertisement of the subject
project. The project provides the following traffic signal installations and
modifications:
1. Avenue Stanford at Avenue Scott - New Signal
2. Seco Canyon Road at Guadilamar Drive - New Signal
3. Soledad Canyon Road at Sand Canyon Road - Signal Modification (Left -Turn
Phasing)
On January -8, 1991, the following bids were received by the City Clerk:
Comoanv Bid Amount
Steiny and Companyi Inc. $147,683.00
Paxin Electric, Inc. $148,891.00
These projects were identified separately in the FY 90-91 Budget; however, to be
cost effective they were advertised as one project. The Engineer's estimate for
this project is $198,500. A total of $325,000 has been budgeted under Account
No. 25-96060-227 for design, contract administration, inspection, and
construction of this project. A forecast for expenditure for left turn phasing
was included in the Capital Improvement` Program concept for the new signals.
During the design of the project, as explained below, the left -tum phasing for
the new signal installations were omitted which reduced the -associated costs.
Combining the three projects into one project also resulted in substantial
savings. Upon completion of the project, excess funds will be reprogrammed -to
fund other Public Works projects.
During the traffic and design analysis of any proposed signalization, left -tum
phasing is. considered. Since left -turn phasing reduces the capacity of an
intersection because through movement must wait for left -turning vehicles, it -is
only proposed when there are insufficient gaps in traffic to allow the left
turns. When the number of left turns and through traffic movements. are
significantly high would left -tum phasing be installed.
ApGnONIED Agenda Item:—

The new signal at Guadilamar is at a tee intersection with a local street and
would likely never need left -turn. phasing; therefore, it is not being
installed. The signal at Avenue Stanford/Avenue Scott can be converted to
left -turn phasing by merely changing the .mast arm. Since traffic patterns do
not justify its installation at this time, left -turn phasing is not proposed for
this signal.
Staff recommends that the project be awarded to Steiny and Company, Inc., the
low bidder. Steiny and Company, Inc. possesses the necessary State Contractor's
license and is a member in good standing.
Award the contract to Steiny and Company, Inc. in the amount of $147,683.00.
