Subject:Contract Change Order Nos. 26 - 28 and increase Contingency Fund to $3,827,871.30 for Bethel Island
Bridge Replacement Project
BACKGROUND: (CONT'D)
for the construction of the portion of the project located over Dutch Slough. The County
attempted to negotiate a resolution to the claim but was unsuccessful. The claim was
pursued by the contractor to the Dispute Review Board (DRB) that was established for
the project as set forth in the project specifications. A hearing was held before the DRB
on April 30th, 2010 with a decision being rendered by the DRB on June 11, 2010. The
County requested reconsideration of the DRB decision which was responded to on July
14th, 2010. The DRB found that the contractor was due additional compensation. Cost
$751,968.43
CCO No. 27:
The project was also delayed for 18 working days due to a utility relocation issue by
AT&T. AT&T had a major trunk communications line serving all of Bethel Island
located in the old bridge. Those lines had to be replaced by new lines in the new structure
before the old bridge could be demolished. AT&T was given adequate notice for the
relocation but failed to begin work in the time frame agreed to prior to the project. They
began relocating their facility on June 15, 2010, completing the work on July 9, 2010,
delaying the project an additional 18 working days. The County intends to seek
restitution from AT&T for the cost impacts to the schedule. Cost $255,290.57
CCO No. 28:
Various delays during the first in-water construction season prevented the execution of
certain elements of the original project schedule. The most significant delay was an issue
with the soil plug and seal course for the cast-in-steel shell piles. The seal courses failed
and material entered the steel shells. After much analysis and discussion it was
determined that some phenomenon at the pile tip occurred, which led to a determination
of differing site conditions. Another delay included time spent analyzing the partial
demolition of the existing bridge, which was ultimately determined to be infeasible.
These delays prevented the contractor from constructing Phase 2 of the bridge
construction during the first in-water construction season. The County obtained an
extended work window for the first season to allow completion of the Stage 1
construction. The County attempted to obtain an extension of the second season in-water
work window, however the regulatory agencies would not provide an extension without
going through a formal consultation process, which would have taken too long to be of
benefit to the project. The Stage 2 and Stage 3 construction of the project were then
combined into a single activity in the second and final in-water work window. The
addition of the Stage 2 work to the second in water season along with the cumulative
delays necessitated the acceleration of the project to achieve a completion of in water
work prior to October 31, 2010. Cost $767,741.00
CONSEQUENCE OF NEGATIVE ACTION:
The lack of approval would prevent successful completion of this contract and preclude
payment to the contractor for compensation due to them for completing the required work.
CHILDREN'S IMPACT STATEMENT:
Not Applicable.
