RE PROPOSAL TO PROVIDE INSPECTION SERVICES
PROJECT 1112100-130
RECONSTRUCTING FORCE MAIN FOR ELDEN PUMPING STATION (PHASE I )
Gentlemen
The following proposal is submitted to provide the necessary
engineering services during the construction phase of said
project
Although the major portion of Phase I has not yet been put out to
bid the District authorized the City to construct the portion of
Phase I under Newport Blvd where the City s repaving project
will take place Since this construction will take place soon
the inspection proposal for all of Phase I is being submitted at
this time Also enclosed for additional information are pages 3
and 4 of the 1992-93 capital improvement program review
Engineering 80 hrs @ $ 59 00/hr = $ 4 720 00
Draftsman 8 hrs @ 47 00/hr = 376 00
Inspection 160 hrs @ 42 00/hr = 6 720 00
Surveying 16 hrs @ 170 00/hr = 2 720 00
TOTAL $14 536 00
The above are maximums and billing will be only for actual time
worked

Project 1112100-130 Dick Sherrick
Reconstructing Force Main for Elden Pumping Station (Phase I)
The project entails replacing or constructing a new parallel
force main for the Elden Avenue Pumping Station The existing
force main (otherwise called a pressure main since the flow is
being forced by a pump causing it to be under pressure) is made
of techite pipe which was briefly used by various agencies in the
mid 1970 s Techite pipe is very brittle and does not stand up
to wear The District has experienced approximately seven breaks
in the line due to various circumstances the last being in
January 1992 which cost over $9 000 to repair Adding to the
problem is the size and flow characteristics of the line the
line is 18 in diameter by far the District s largest and the
flow is in excess of 3 500 gallons per minute (gpm) Therefore
any break in the line causes an immediate large sewage spill
Also once a break occurs the techite becomes very hard to
repair
The District has already taken steps to replace portions of the
techite line with ductile iron pipe the choice material used in
all new installations When CALTRANS constructed the Mesa Drive
overcrossing bridge over the Costa Mesa Freeway (CMSD 1112100-
110) the District specified ductile iron pipe Also when the
Elden Avenue Pumping Station was reconstructed (CMSD 1112100-99)
the District replaced the section between the station and the
bridge with ductile iron pipe The remaining section to replace
begins at the west side of the bridge and runs in the Costa Mesa
Freeway across the Fairgrounds property to Fair Drive and in
Fair Drive to the main fairground entrance where it discharges
into a gravity sewer The length of line is approximately 2 200
feet

The budget for the project was obtained by proposing a new
appropriation of $300 000 and combining it with the unused
$250 000 from last years Pump Station Abandonment Project (CMSD
1112100-127) The abandonment project is being delayed due to
the County Sanitation District prioritizing other projects ahead
of their proposal to construct the downstream portions of the
abandonment network
It is not clear whether the $550 000 is sufficient to cover the
cost of design, construction and inspection of the entire 2 200
feet due to the expensive nature of working in the CALTRANS
right-of-way therefore, the project will be designed in its
entirety but most likely be constructed in two phases The
second phase will be proposed in the 1993-94 budget
An estimate of the project costs is as follows
Design (includes research field surveying design $ 19 500
soils engineering preparation of project
plans and specifications plan processing and
advertising for bids)
Construction 465 500
Inspection (includes administration construction 15 000
staking and inspection)
Reserve or Contingency 50 000
TOTAL $ 550,000
