Subject: Request for Amendment #1 to our Construction Management & Inspection Contract
Dear Tim:
We are writing to request an amendment to our original contract for inspection and construction management
services associated with the Gobbi Street/Oak Manor/Babcock Lane Intersection Improvement Project. Our
original contract was for the amount of $123,020 and we are requesting an additional $22,095. This request
for additional budget is to compensate Green Valley for additional work performed from October 25, 2010
thru the completion of the project. The project is estimated to be complete December 3, 2010 for the physical
work, with an additional 7 days needed for the closeout work (change orders, PG&E claim, Granite claims,
as-built drawings, final payments, project files). Factors that could impact this estimated completion date are
the weather and removal of the PG&E joint pole. In addition, based on conversations with the Contractor,
we have taken into account the fact that the project will be shut down on Thanksgiving week.
have estimated that inspection will average 4 hours per day for 10/25/10 through 11/1910 and 11/29/10
through 12/5/10.
Inspection = 25 days @ 4 hours/day @ $117/hour (includes vehicle) = $11,700.
1 have estimated that Construction Management will average 3 hours per day for 10/25/10 through 11/24/10
and 11/29/10 through 12/10/10.
CM = 33 days @ 3 hours/day @ $105/hour = $10,395.
Total for Amendment #1 is $22,095.
Additional Scope of Services
The following construction issues have resulted in delays to the project and added an increased number of
working days, which necessitated additional inspection and construction management time.

PG&E delayed removing the gas main from the creek channel from approximately May 2010 until the end of
October 2010. The gas line was so close to the wing-wall footing that the Contractor was forced to hand-dig
for the footing. The gas line was ultimately exposed and required the Contractor to pull it away from the
footing per direction of PG&E.
Additionally, Fish & Game and Water Quality permits required all work to be out of the stream area by
October 15, 2010. We were able to obtain a Fish & Game extension. In spite of numerous phone calls, e-
mails, & meetings, PGE delayed removing the gas main out of the stream until October 22, 2010. The PG&E
delay also delayed the Contractors work on the wing-wall & installation of rock slope protection (RSP) in the
stream area.
PG&E Joint Pole
PGE has delayed removing the joint pole from the middle of the intersection until November 19, 2010 from
the original date of May, 2010. The Contractor was able to do some work around the pole but this delayed
the overall completion of the project, pushed the project into the rainy season, and added change order costs
to the City.
Additional Design Work
There were changes to the project that required design work. In lieu of having the designer (in Eureka)
prepare these designs, we determined that the City could save money and delays to the project if Green
Valley did this design work. There were ten small design projects for adding new facilities and re-designing of
existing facilities. This design was tracked on a separate charge number although the time spent has been
charged against the CM budget.
Relocate Pedestrian Bridge at School
There is consideration for replacing the existing pedestrian bridge at Oak Manor School with the Gobbi
pedestrian bridge that was removed from the Gobbi Project. Our additional CM time has been for various
meetings with the school officials, Assistant City Manager, Green Valley survey crew, Contractor, and City
Public Works.
"Friends of Gibson Creek"
I received about eight a-mails from this environmental watch dog group that the City asked me to respond to.
In addition I was required to attend meetings with City Planning Department, on site with an arborist, and
prepare change orders for special tree protection measures.

During construction the Contractor installed the pre-cast bridge sections approximately 1" too high. Added
costs to the CM budget were for the Green Valley survey crew to check grades to determine if this affected
anything else, like the profile grade.
Electrical conduit
The City Electrical Department had the Contractor install new electrical conduit through the new Bridge and
connect to new vaults under a change order. I understand that that the Contractor's installation cost will be
reimbursed to Public Works. However the CM and inspection costs were charged against the original budget
and there were about 20 hours of my time for design and meetings and 6 days for inspection time.
If you feel that we have overlooked something or are missing any relevant information, please do not hesitate
to contact me.
Thank y r y r consideration in amending our contract.
