Consideration of Final Completion for the SCADA Reliability
Improvement Project Phase 3
CONSENT
1. WHY THIS MATTER IS BEFORE THE BOARD
The SCADA Reliability Improvement Project Phase 3 is complete. A resolution
accepting the project as complete requires Board approval.
2. HISTORY
In August 2013, the Board awarded the construction contract for the SCADA
Reliability Improvement Project Phase 3 to Curtis and Sons Construction, Inc.
(CSC). This project involved the installation and testing of fiber optic cable to six
District facilities. CSC began work in September 2013 and completed the project in
December 2014.
The original bid price was $328,041. At the time of award, the Board also established
a 10 percent change order allowance for a total authorization not to exceed $360,845.
In December 2013 a progress report on Phase 2 of the SCADA Reliability
Improvement Project was presented to the Board. It was noted that several
deficiencies needed to be addressed for project completion. Terry Hanson Electric
(THE), the Phase 2 contractor, indicated they would not complete this work and a
deductive change order was negotiated with THE. The Phase 2 project was closed out
in January 2014.
The remaining Phase 2 work was transfered to Phase 3 requiring an increase in the
change order allowance for Phase 3. The Board approved an increase in the change
order allowance from $32,804 to $82,804 with the resulting contract total not to exceed
$410,845.
3. NEW INFORMATION
During the course of the project eleven change order requests were reviewed by staff
and accepted. These change orders totaled $66,499. This amount did not exceed the
$82,804 change order allowance established by the Board of Directors. The items
generally fell under the following categories:
Additional work for grounding;
Changes to vault and splice closures sizes;
Addition of a splice location;
Relocation and installation of equipment at the Donner Lake Substation; and
Testing and splicing fiber installed during SCADA Reliability Improvement
Project Phase 2.

The reconciliation of Bid Quantities vs. Actual Constructed Quantities results in a credit
of $15,683.16 to the District and payment of $422.40 to CSC. Attachment 1 shows the
differences between bid totals and the amounts actually constructed. The variances
are associated with over or under estimates in the bid quantities for fiber optic cable.
The resulting total contract price was $379,279.24, which does not exceed the
authorized contract amount of $410,845.
In December 2014 District staff performed a final walk through of the project and
determined that the project is complete. A draft resolution accepting the project and
directing that a Notice of Completion be filed is included as Attachment 2.
4. FISCAL IMPACT
The original bid price was $328,041. Once adjustments are made for the items
described above, the final contract price is $379,279.24. This total is below the
December 2013 Board authorization of $410,845.
5. RECOMMENDATION
Adopt Resolution 2015-02 accepting the SCADA Reliability Improvement Project
Phase 3 project as complete and authorize the filing of the Notice of Completion.
