Subject Cost Estimate for Completion of Newport Beach Water Main Project,
Reach No. 3 Punch List Items, C.K. Construction
Dear Mr. Sinacori:
I
Per our discussion last week, attached is AESE's cost estimate for completion of
the punch list items for C.K. Construction's Reach No. 3 project. This is the same
estimate I sent to the surety, TIC, back in May. I have based the pricing on the
attached punch lists and on the meeting and site inspection we had with you on
Wednesday, April 30'h. As we discussed at that meeting, the bulk of the reau-tiring
work involves re-grading of the west levee road and placement and compaction of
AC grindings on the road, along with some street repairs per the Fountain Valley
b.
punch list. As you can see by the cost estimate, I have included an allowance for
some minor block wall repair, gate and fmcu repair- disposal of excess soil. etc.
In our discussions during the job walk, you indicated that CNA may be
perthrming most, if not all, of die wall repair. Obviously, this item could be
removed from our estimate if CNA or others have completed this work.
The placement of the AC grindings; will include regrading and cutting the levee
road using a mono- grader and loader, loading and hauling of the grindings; from the
Fountain Valley y. in
yard rising I 0-wheal dump trucks, spreading of the grindings
using a loader and moto-grader, and compacting the grindings using a smooth-
wheel roller. We will have a water truck on-site at all times To provide dust
control and moisture conditioning. We will also provide a loader at the Fountain
Valley yard to load the grindings from the stockpile. We will use subcontractors
to complete the street repairs, fence repairs, and block wall repairs, as necessary. .
Aftcr our phone conversation today, we have located a copy of the Reach No, 3
contract. I would suggest that we take the relevant portions of Section 1, Scope
and Control of the Work, and modify them appropriately to reflect the remaining
punch list items. We will need to agree on acceptable language for payments,
liquidatod damagag, and warranty. We are prepared to provide performance and
payment bonds and proof of the required insurance coverage prior to commencing
the work. I suggest that we schedule a meeting at your earliest convenience to
discuss the completion of the work iron
and out any contractual details.
From a scheduling standpoint, I estimate that the grading and placement of the AC
grindings will require approximately 3 weeks to complete (I week per section

between the main east -west streets). The other minor repair work to the fences,
gates, and block walls will be performed once the grindings have been placed in
each section. The street repairs can be performed concurrently with the placement
of grindings. Therefore, I estimate that the total duration of the field work should
be 4 -5 weeks, depending on the amount of miscellaneous repairs (walls, etc.)
which may be necessary in each section. As we discussed, we will plan on
completing all of the punch list work within one section before moving on to the
next section. we can sequence the work for each section in whatever manner you
feel is appropriate. On the frontend, we will need approximately one week from
NTP for mobilization.
The cost estimate assumes that we will be able to obtain the asphalt grinding
material from the City of Fountain Valley's maintenanco yard. I have included
two months of storage L $1.500 /month in my cost estimate.
I have included three separate mobilizations in the estimate because, at the time it
was originally prepared, the grindings were not going to be available at one time.
However, it may be that sufficient grinding have now been accumulated so that we
can perform. die work during a single period. If this is the case, you will realize
some savings in terns of the mobilization costs.
I have also included a cost for completing ac -built drawings for both Reach 2 and
Reach 3. The price assumes that we will be able to obtain all of the necessary
information from C.K. and that our CAD staff will take the information provided
and generate a set of drawings. If we cannot obtain adequate information from
C.K., the cost could be substantially higher.
If we are able to get a contract in place and begin the work by mid- August, we
should be able to complete the work by the end of September at the latest,
provided the asphalt grindings are available. If you have any questions, please
foul freu to contact me at (8 18) 786 -2373.
