~: On October 27, 1988, sealed bids for the design and installation of District
Project No. 10037, Pumping Stations Telemetry, were received and opened. The Board of
Directors must award a contract or reject proposals within 60 days.
BACKGROUND: The Plant Operations Department Maintenance Engineering staff has completed
preliminary design for a pllllping stations telemetry system. This project will connect
the pumpi ng stati ons al arms to a central monitori ng unit at the treatment pl ant. The
telemetry system will upgrade and replace an existing telephone signal ing system and
enable an operator to identify specific alarms at each of 14 remote sites. The central
monitoring unit, located in the Treatment Plant Computer Room, will interface with the
existing plant mainframe computer for all data logging and operator input functions.
The project was readvertised on October 5, 1988, because the original bi ds were decl ared
non-responsive and were rejected. Four new bids were received (listed on Attachment 1).
Bids provided for the final design, furnishing the system hardware and software, and
installing the treatment plant central monitoring unit. Installation and field wiring
of the remote telemetry units (RTUs) will be performed by District forces.
The requi rements for the tel emetry system's hardware (compati bil ity with the pl ant's
mainframe) limited the number of vendors of this equipment. The apparent low bid of
$72,128 received from Pipeline Systems Incorporated meets all of the requirements of the
specifications. The engineer's estimate for this equipment and installation was
$80,000.
This project was budgeted for $130,000 in the 1987 - 1988 Capital Improvements Budget.
An additional $30,000 is requi red to cover additional requi rements, which were not
identified in the original project. The original cost estimate did not include the
telemetry of data from the Concord North meter or the Concord Pumping Station, which has
been added, or the full level of equipment redundancy needed for stand-alone operation
of the central monitoring unit. A project estimate is provided in Attachment II.
This project is included in the 1988 - 1989 Capital Improvements Budget, page CS-I08.
District staff has concluded that the proposed project will have no significant
environmental impact and has filed a Notice of Exemption.
RECOtIENDATION: Authorize award of contract for Di stri ct proj ect No. 10037, Pumpi ng
Stations Telemetry, to Pipeline Systems Incorporated.

ISSUE: Sealed bids for District Project No. 20070, Influent Gate Opera~ors, were
received and opened on November 9, 1988. The Board must authorize award of a
contract or reject all bids within 60 days of opening of bids.
BACKGROUND: The existing influent gates control the raw wastewater flow to the
inlet building. If one or more of the influent pumps fail during a peak wet
weather event, the wastewater level in the inlet building rapidly rises and
creates a dangerous condition for District personnel working in the building and
also ,threatens equipment in the room. The existing gate operators do not provide
adequate closure speed to protect equipment or personnel. This project includes
the installation of two new gate operators which close at a faster speed along
with electrical and instrumentation modifications for both local and remote
control. The two gate operators were prepurchased by the District in August 1988.
This project is described in the FY 1988-1989 Capital Improvement Budget, page
TP-82.
Plans and specifications for the project were completed, and advertisements
inviting the submission of sealed bids were placed in the Contra Costa Times on
October 25 and 31, 1988. Two bids were received and opened on November 9, 1988.
The bid tabulation is shown in Attachment 1. The two bids received were $66,302
and $69,800. District staff reviewed the bids and has determined that the lowest
responsible bidder is Amelco Electric of San Leandro, California with a bid of
$66,302. The Engineer's Estimate for construction cost was $78,000.
A Post Bid/Preconstruction Cost Estimate is presented in Attachment 2. The
estimated total project cost is $145,400 which includes all design and
construction work. An additional authorization of $93,800 is required to complete
the construction of the project. Funds for this project are included in the FY
1988-1989 Capital Improvement Budget.
This project has been evaluated by staff and determined to be exempt from the
California Environmental Quality Act (CEQA) under District CEQA Guidelines Section
18.2. A Notice of Exemption was filed with the Contra Costa County Clerk on
July 28, 1988.
RECOMMENDATION: Authorize award of the construction contract for District Project
No. 20070, Influent Gate Operators, to Amelco Electric, the lowest responsible
bidder.

Repair Project, Martinez COP 3885), and the work is now ready for acceptance.
BACKGROUND: This storm damage repair project replaced an eight-inch public sewer
main at Vista Del Diablo in Martinez that was damaged during the winter storms of
1983. The work included the replacement of the damaged existing eight-inch sewer
main with approximately 400 linear feet of eight-inch ductile iron pipe and the
installation of two manholes, as well as the repair of an existing downstream
eight-inch sewer main that was found to be cracked in three locations. The slide
restoration work was completed by others prior to the District's project. This
project is described in more detail on pages CS 85 and 86 in the FY 1988-89
Capital Improvement Budget.
Silva's Pipeline of Hayward was issued a Notice to Proceed on October 6, 1988.
The contract completion date was November 5, 1988. Due to favorable weather and
diligent contractor efforts, all contract work was completed prior to that date.
There were no change orders issued on the project.
It is appropriate to accept the contract work at this time. A detailed accounting
of the project costs will be provided to the Board at the time of close-out.
RECOMMENDATION: Accept the contract work for constructi on of the Vista Del
Diablo Storm Damage Repair Project, Martinez <DP 3885), and authorize the filing
of the Notice of Completion.

ISSUE: At the request of LAFCO, the resolution which the Board passed on October
20, 1988, ordering the territory contained in Rassier Ranch Boundary
Reorganization to be annexed into this District, should be revised to also order
the territory to be annexed into East Bay Municipal Utility District (EBMUD).
~ACKGROUND: Pursuant to the Local Agency Formation Commission Resolution (LAFCO
88-27), the Central Contra Costa Sanitary District (CCCSD) Board of Directors is
responsible for the completion of the Rassier Ranch Boundary Reorganization. This
includes ordering the territory to be annexed into both the CCCSD and EBMUD.
This is the first boundary reorganization in which this District was designated as
the conducting authority and, as such, the Board action was intended to include a
change to both the boundaries of CCCSD and EBMUD. This fact was not fully
understood by staff when the original resol ution was prepared. The resol ution
passed by the Board did not include any action with respect to the annexation of
the territory to EBMUD. A new resol ution has been prepared which compl ies with
the intent of LAFCO.
RECOMMENDATION: Rescind Resolution No. 88-140, and adopt a new resolution
"orderi ng the Rassier Ranch Boundary Reorganizati on" which i ncl udes orderi ng the
subject territory be annexed to both the CCCSD and EBMUD.

BACKGROUND:

need for a
Construction
Unanticipated subsurface conditions have been encountered during the
of the I-680/SR-24 Sewer Relocation Project which have created the
change order in excess of $50,000 to the contract with Dalton
Company (DCC).
This project is being implemented under a Ut1l1t1es Agreement with CalTrans and
all related costs associated with the project are reimbursable from CalTrans. As
part of the project, DCC is required to jack approximately 350 feet of 24-1nch
diameter pipe casing from the Elk's Lodge on Creekside Drive in Walnut Creek
across the flood control channel and under the I-680 freeway to South Main Street.
In DCC's f1 rst attempt to jack the cas1 ng, at approx1matel y 30 feet 1 nto the
embankment of the I-680 off-ramp, hard sandstone was encountered and the cas1 ng
became firmly wedged in place. Efforts to withdraw the casing were unsuccessful.
The casing was abandoned and the work resumed three feet away from the abandoned
casing with a rock cutting auger. Jacking commenced at the second location. At
approximately 50 feet into the embankment, an unknown reinforced concrete
obstruction was encountered. DCC core drll 1 ed the obstruction for th 1 ckness
investigation and found that it is at least 22 inches thick. The investigation
could not proceed further because the maximum length of the coring equipment was
reached. The origin of the concrete is unknown at this time. The work on this
portion of the project has been temporarlly suspended to allow for evaluation of
al ternat1ves.
Staff has evaluated eight alternatives in an attempt to resolve the construction
problem. Five of the eight viable alternatives were selected as feasible and
quotes were obtained from DCC. A joint review of the quotes was made by the
District staff and CalTrans' representatives. Based on the cost and risk factors,
the alternative of rerouting the sewer line between the flood control channel and
the I-680 freeway and el 1m1 nat1 ng the need for j ack1 ng under the freeway was
selected for negotiation with DCC. DCC's original quote for this work was
$162,479.00. The negot1 ated cost 1 s $138,000. D1 strict Counsel has conf1 rmed
that bidding is not required since the work is incidental to the carrying out of
the original scope of work.

POSITION PAPER
PAGE 2 OF 2
DATE
November 10, 1988
The negoti ated cost excl udes the cost cl aimed by DCC for encounteri ng hard
sandstone in the first attempt to jack the casing. District staff and CalTrans'
representatives are maintaining the position at this time that the problem with
sandstone does not fall within the stipulations of the differing site condition
portion of the contract.
Easements from both the county and the Elk's Lodge are required for this
alternative. The required funds for the easements are available from the project
contingency budget.
The total change order cost is $138,000, which is 74 percent of the allocated
project contingency budget of $185,800. Since the total construction work is less
than 10 percent completed at this stage, additional contingency budget is
requi red.
A total authorization of $75,000 from the Collection System Program Contingency
Account is requested which will be added to the project contingency budget.
Si nce Cal Trans reimburses in arrears, the Board must authorize funds for the
