MEMORANDUM 
COMMISSION AGENDA    Item No.   5d
Date of Meeting   February 9, 2010
DATE:   February 3, 2010
TO:     Tay Yoshitani, Chief Executive Officer
FROM:   Ralph Graves, Managing Director, Capital Development Division
SUBJECT: Change Order #004 for the Terminal 115 Berth 1 Modifications Project Contract
MC-0316208
AMOUNT OF THIS REQUEST: $437,000   SOURCE OF FUNDS: Project Contingency
ACTION REQUESTED:
Requests authorization for the Chief Executive Officer to issue Change Order Number 004 for
the Terminal 115 Berth 1 Modifications Project for the Not to Exceed Net amount of $437,400.
SYNOPSIS:
This project is for the construction of a new berth at T-115 and the site has had various uses over
its history. The project includes:
The demolition of existing pier structures and infrastructure.
The installation of approximately 473' of new sheet pile seawall.
Dredging the new berth to accommodate barge loading in all tidal conditions.
Install new mooring system including winches, dolphins and fender piles.
Install a new cargo loading ramp and ramp lifting system.
Upgrade new water and power/communication services.
During sheet pile installation for the construction of the new seawall, an extraordinary amount of
underground obstructions were encountered due to previous dock remnants and debris (e.g.
lengths of chain, logs, boulders, etc.). Many more hours were spent driving the sheet piles to the
proper depth than anticipated. As a result, the contractor was asked to accelerate other activities
due to the closing of the permitted in-water work period on February 15. The contractor
proposed using a land crane in addition to the derrick barge in order to work on more activities
concurrently. It was initially thought that the cost of the land crane versus the derrick would
result in no additional costs; however, as more underground obstructions were encountered,
those costs also increased over the bid item prices for this work. Since many of the sheet piles
did not reach the proper depth, additional work was required by divers to trim the excess length
of those sheets so that the fishnet guards could be installed.
A change order is required to compensate the contractor for these increased costs. Because the
final magnitude of the change will not be known until all the in-water work is completed, the

change order will be issued for a not to exceed additional cost of $437,400. Since some of the
work was performed in a different manner than bid, a credit was requested for the relevant bid
items. Including those credits, this change order has an estimated absolute value of $812,600.
The funds to pay for this change order are part of the project contingency funds that were
included in previously approved authorizations of $35,219,410. No additional project funds are
being requested as a result of this change order.
CHANGE ORDER DESCRIPTION AND JUSTIFICATION:
The following information relates to the pending change order scope and cost:

piles and acceleration of work necessary to complete all in-water work by February 15,
2010. Bid Items 24, 25 & 30 are related to CB's 5, 7, & 3 respectively and will be
deleted since the work associated with these bid items will be incorporated into this
change order. The contractor shall proceed for a total amount NOT TO EXCEED
$437,400.

CB #7: Use Land Crane to Drive Fender Piles (est.)                 $85,000.00
FD #3: Accelerate work by working 4 Saturdays in January (est.)       $85,000.00
FD #5: Cut off excess lengths of the sheet pile wall (est.)               $70,000.00
FD #6: Mobilize a larger pile driving hammer (est.)                  $20,000.00
Delete Bid Item #24: Drive 16" D Fender Pipe Piles                ($37,200.00)

Net CO Not To Exceed Amount                       $437,400.00
Justification: The delays encountered due to the underground obstructions would keep
the work from being completed prior to the end of the in-water work window.
Consequences of not proceeding: Possibilities include Berth 1 not being completed this
year rendering it unusable to the tenant, Northland Terminal Services, until the next inwater
work period; or that the unfinished in-water work would violate Environmental
Protection Agency or tribal agreements.
