tSUBJ: Approve Revised Plans and Specifications for Utility
Telemetry System, Authorize Advertising for Bids
IProject No. 90-3
As will be recalled, the City Council rejected bids for the
I utility telemetry system on June 4, 1990 and authorized the
preparation of revised specifications to consider a radio-based
system as well as to more thoroughly research the system
I expansion potential . The firm of Orr-Schelen-Mayeron &
Associates was contracted to prepare the revised specification.
Staff has been actively involved in visiting similar
1 installations and some of the system suppliers to further define
the appropriate system for the City. Although painful and
time-consuming, I believe this has been very beneficial and the
system that we are currently specing will be a much better
Isystem, although more expensive initially.
A copy of the bid proposal form is attached and the overall
I system plan is also provided for information. The biggest
modification to the proposal has been the decision to go with
radio telemetry for communicating between the remotes and the
base station. Our radio propagation sub-consultant, Mr. John
DuBois , has made _a preliminary review of the system and feels
comfortable that the 900 megahertz (MHz ) band which is reserved
for data and signal transmissions of this nature is suitable for
I the City ' s installation and the integrity and reliability of the
radio communication will benefit us in the long run. When an
operating license is granted, the operating frequency is then
1 protected.
The radio element is expected to add approximately $110,000 to
the installation cost of the system; however, it is expected that
I the City would see a five-year payback of this initial cost based
on the savings in monthly telephone charges which we would have
incurred using telephone lines .

' We have also upgraded the automatic dialer system in the spec
from that which was originally proposed to provide for discreet
' alarms to be transmitted to on-duty personnel to identify what
specific site(s ) are experiencing problems allowing staff to
respond directly to the site instead of to the central computer
to interpret the alarm status. This will shorten response time
' and more effeciently allow staff to respond to system problems.
This has added approximately $5 ,000 to the cost estimate.
The specification will provide one integrated system with new
remotes at all stations. It also has built-in flexibility for
the future for allowing additional analog inputs and outputs. In
' an effort to avoid price gouging with future system add-ons, the
specification calls for bidders to provide their protocol
language for the central processing unit such that additional
RTUs (remote telemetry units ) can be acquired from any of a
' number of manufacturers in the future and the City will not
experience sole source price gouging as a result.
' The current cost estimate for the system ranges from $210 ,000 to
$225,000 . As noted, $110 ,000 of the increase is due to the radio
telemetry. The City had budgeted $100 ,000 between the sewer and
water expansion funds for this project. Fortunately, due to the
revised scope and low bid received for the Murray Hill water
tower painting, only $65 ,000 out of the $120,000 budget will be
needed for painting the water tower; therefore, $55 ,000 remains
in Fund 402 from this element. Similarly, staff had budgeted
$60 ,000 for watermain expansion on County Road 17. Due to some
mapping and as-built inaccuracies, the computer modeling of the
' County Road 17 watermain was in error and a more recent modeling
with the accurate system configuration indicates no need for this
watermain improvement. Therefore, an additional $60 ,000 for this
element is available from Fund 402. This provides total
available funding of $215 ,000 which could be dedicated to this
project.
' The specification has also been prepared to require the bidders
to guarantee their pricing for a period of one year such that if
budget restrictions dictate, the City could pare back the amount
' of the award and add on additional elements of the telemetry
system in the 1991 budgetary year and still take advantage of the
current pricing obtained through the bidding.
' It is therefore recommended that the revised plans and
specifications for the City 's utility telemetry system as
prepared by OSM be approved and authorization given for bidding.
The bid opening date is scheduled for July 27 , 1990 .
