Re: Additional Services Associated with Water Main Improvements at Gobbi and State
Streets
Dear Rick:
Per your request of April 14, 2008, we have enclosed a brief scope of services and associated fee for
the changes associated with the modifications to the original water main project that we have been
working on.
Our Understanding
We understand that due to budget constraints it is necessary to modify the City's original scope and
direction of designing and advertising water main replacement work at four (4) separate locations -
to be advertised at once under one contract. At this time, each of the four locations will be designed
and packaged as individual projects to be advertised as budget allows. The City will proceed with a
modified scope of work at the Gobbi Street location - to be advertised in 2008. The remaining
three locations will be advertised at a later date. Project specifications are to address only the Gobbi
Street location at this time.
Modifications to the Gobbi Street location will include the deletion of the original 8" main
replacement between South Oak Street and State Street and instead extending the replacement of
the 12" water main in State Street by an additional 210 feet south from the original termination
point, which will take it to the joint utility point on the west side of State Street. City forces will
install a 12" gate valve in the existing 12" main as detailed in the aforementioned letter. City forces
will also install an 8" gate valve near the east end of Gobbi Street. We will be responsible for the
design of an offset to make the connection from the new 12" main to the existing 8" AC main in
West Gobbi Street.
Topographic Mapping
We need to extend the original topographic mapping that was obtained to pick up the limits of the
additional work on State Street. We will pick up surface features and any underground utilities that
are apparent.
Prior to field surveys, we will mark for USA to assist in identifying underground utilities that may be
in conflict. Mapping will include the project area covering a sufficient distance beyond the proposed
improvements to properly design the project.
Deliverables: Hard Copy of Topographic Survey Data and Mapping and
Diskette in AutoCAD 82006

75% Design and Improvement Plans
The 75% design documents will have enough detail to allow the City's Public Works Department to
review our approach to the revised project scope. The plan and profile sheets will indicate existing
right-of-way lines and any pertinent easements, topographic features, and existing utility systems. It
is expected that there will only be 1 improvement plan and profile sheet for the new work. Project
specifications will be completed for the Gobbi Street intersection to be used for subsequent
advertising.
100% Design and Improvement Plans
A 100% submittal of the plans will incorporate all comments from the 75% review, as well as results
of utility company reviews of the plans. Final horizontal and vertical alignment, any lateral and
services connections, and details will be included. Construction documents will be prepared in
accordance with the City of Ukiah Design and Construction Standards.
Fee for Additional Services $6,975
Thank you again for the opportunity to submit a proposal for our services. Should you accept our
proposed scope of services and associated fee, Green Valley can begin work upon authorization to
proceed. We look forward to hearing from you and please do not hesitate to contact us with any
questions you may have.
Sincerely,
Liz Ellis, P.E
