Dutra Progress Schedule Update, Nov 20, 1996
Serial Letter No. CESPN-CT-95-C-0003-0014
Dear Mr. Johnston:
Reference is made to your contract DACW07-95-C-0003 for (-)42' Navigation
Improvement, Oakland Inner and Outer Harbors, Alameda and San Francisco
Counties, California.
This confirms understandings from the meeting with Tom Keesling on November 13,
reviewing your proposed updated schedule provided with your transmittal letter
dated November 8, 1996. We received this information on November 12, 1996.
Preliminary review was set out in the notes of the Progress Meeting on November
12 so that you can begin thinking about our objectives and concerns. The review
meeting held with you on November 13, 1996 presented an initiative and
highlighted steps needed to carry it forward. You are hereby directed to meet
with COE on November 21, 1996 at 0900a in the office of Max Blodgett on
performing the following steps:
1. This letter modifies the understandings from the November 13 meeting where
Dutra asked that COE develop details from the survey performed by Dutra's
subcontractor, GB Star company, on the distribution of the 4M CY reported by GB
Star as remaining to be dredged in order to reach plan grade, as of the survey
date, several weeks ago. Upon review, COE has determined that there is no
evident support for the quantities in each acceptance area Dutra proposed in
its Nov 8, 1996 schedule submission. Dutra should coordinate with its
subcontractor, GB Star, to determine such details as are necessary in order to
calculate the amount to be dredged and the consequent level of effort with
respect to time, equipment, labor and all other resources to dredge the
remaining material to plan grade in each acceptance area Dutra proposes.
Accordingly, you are directed to do so, and further you are directed to notify
us in advance if you expect to incur any additional expense in order to comply
with this direction. Based on such research as you determine necessary to
prepare a practicable schedule to dredge the project to grade, Dutra shall then
submit a schedule for accomplishing this objective.
2. You are directed to change the order of performing your proposed acceptance
areas so the schedule provides continuity of adjacent areas with the exception
of completing the Galbraith disposal site.
3. You are directed to include in the schedule the activities for the Navy
Sewer Line, showing the time alotted for completion of your shoring design to
construct the crossing beneath the Union Pacific Railroad, procurements and
construction, including the relationships with other work activities. Any
other known obstructions or interferences should be shown on your revised
schedule.
4. You are again directed to submit a Contract Management Plan, as specified
in COE serial letter #0013 dated November 4, 1996, which plan you indicated
during the meeting on November 13, would be submitted to us on November 15, but
which was not submitted. We need this plan to evaluate Dutra's ability to
perform its proposed schedule, and to complete this contract. A key aspect of
the Contract Management Plan is the assignment of qualified personnel to
prepare the weekly Plans of Dredging Operations called out in secton 02480 para
4.2, which Dutra has not been able to perform. These plans show Dutra has
adequately planned the daily implementation of its project completion schedule,
as intended by the contract.
5. You are directed to show a single completion date for the project based on
the GB Star survey dated 30 October 1996 entitled Complete Condition Survey of
the entire project area for Modification #P00030, and the revised acceptance
plan you propose. Your letter of November 8, 1996 says the job will be
finished on October 4, 1997, but your schedule documents indicate the
completion date is July 30, 1997. Your revised schedule should correct this
discrepancy based on the amount of material to be dredged.
6. Submit an explanation of how the average daily production rates for
dredging for the Paula Lee and the Antone were calculated based on the record
of dredging to date.
7. Address the observation by GB Star at the November 12, 1996 Progress
Meeting that the cut depth over the remaining project area is smaller than the
depth of areas where dredging has been performed in recent weeks, with the
evident consequence that production rates should decline. How do you expect to
maintain production at the proposed rates under the conditions forcast by GB
Star of smaller cut depths in the remaining acceptance areas?
8. You are directed to include in your schedule the proposed dates of
performing the items shown in the Gahagen & Bryant list dated October 30, 1996,
which list was submitted to you attached to our serial letter #0013 dated
November 4, 1996. Items on the G&B list which you object to performing shall be
so identified and an explanation made of why you believe it is not responsible
for performing such tasks.
9. You are directed to adequatley identify any and all schedule documents in
your re-submission. This includes the plan drawing of the revised acceptance
areas, the Schedule sheets, the Production sheets, so that each document is
dated, shows it was produced by you for the Oakland Harbor project, shows the
name of the person who prepares it and the source for the information it
contains, including any calculations needed to convert source data for the
information in Dutra's schedule documents. Activities shown on the schedule
need to be numbered and identified on the Acceptance Areas plan sheet. The
Acceptance Areas plan sheet should be color coded so that the proposed order of
acceptance reflects the broader pattern of progress on useful areas of the
project, all to facilitate effective evaluation of the practability of your
schedule.
Sincerely
Thomas Benero
