Attention:  Thomas Benero, Contracting Officer

Reference:  Contract No. DACW 07-95-C-0003

Subject:  Sewer Line Crossing


Dear Mr. Benero:


Attached, please find work description from our Consultant, GEI, drawings and
cost proposal for the additional shoring required at the Union Pacific
Railroad site where the pipeline makes landfall as described on the contract
drawings.




Also attached is our consultant's description of the work involved in changing
the alignment some 500 feet eastward, drawings and cost proposal for the work
that would be additive to the current item price.




Summaries of each element and net cost/savings for changing the alignment and
satisfying the demands of Union Pacific Railroad that slope stability be
assured.










As you are aware, this situation of instability at the proposed sewer line
interception whith land at the UPPR site has been known for many months.  We
have attempted to get the resolution without the formalties we are now
involved in, to no avail.




We have attempted to be as proactive as possible to help solve a problem.  We
believe there is a solution that will satisfy the demands of Union Pacific
Railroad while minimizing costs.  The alternate pipe route presents this
solution as shown in the attachments.




Your expeditous review is solicited.  If there are questions, please contact
us.




Sincerely,


DUTRA DREDGING COMPANY
