COMMISSION AGENDA                Item No.     5b
Date of Meeting  November 10, 2009

SUBJECT: Modification of scope for barge layberth improvements at Terminal 25,
Pier 28 and Terminal 46
ACTION REQUESTED
Request for Port Commission to modify the scope of previous authorizations to complete
construction of necessary improvements to the fendering and terminal systems at
Terminal 25 (T25), Pier 28 (P28) and Terminal 46 (T46) for no net change in the current
$300,000 authorization.
SYNOPSIS 
This request falls under and is part of the "Industrial Moorage Initiative" which was
presented as a Policy and Staff Briefing in public session on June 3, 2008.
The Capital Development Division (CDD) received authorization on March 10, 2009 for
$300,000 in funding for improvements at three sites identified in the Seaport Planning
Barge Layberth study of July 2008.
The original scope included the replacement of deteriorated fender piles at both Terminal
46 & Pier 28, and security fencing and site improvements at Terminal 25.
The security improvements at T25 were completed in May 2009. This vessel berth and
adjacent dock area located at the south end of T25 has been leased to Olympic Tug and
Barge. Design, permitting and cost estimates have been completed for the other two
sites. Total cost to date for planned improvements on all three sites is $109,784.
However, staff has discovered additional damage and deterioration to piling, chocks,
walers and walkway systems at Pier 28 and Terminal 46. Staff is now forecasting total
cost of these improvements to be above the original approved budget to complete all
required remaining work.

Staff recommendation is to concentrate the remaining authorized funds on expanded
repairs at Pier 28, and to forego repairs to the fender system at the north berth at Terminal
46. This revised approach would improve the fender system at Pier 28 while remaining
within the original $300,000 authorization.
PROJECT SCOPE OF WORK AND SCHEDULE: 
Expand scope of repairs at Pier 28: The revised scope proposed at Pier 28 would
include repair to the eight piles originally identified in the condition survey, plus two
additional broken piles identified since the survey, and associated chock, waler and
walkway repairs to upgrade the condition of the berth, and improve safety for line
handling and vessel berthing operations.
Replace two fender piling at the NE corner of Terminal 46 for the Pilots: Staff also
recommends the installation of two fender piles at the NE corner of Terminal 46
North to provide protection of the pier structure and the ladder used by Puget Sound
Pilots. Installation of these two fenders could be performed economically by the
contractor with minimal mobilization/demobilization costs, and can be performed
under the existing permits in place for fender improvement work.
Do not repair fenders at the North berth at Terminal 46 at this time: While this
revised scope would not address the fender pile improvements along the berth at the
NW face of Terminal 46 the recommendation to defer this fender work is based on
additional information received from barge industry representatives that this berth
area represents the least useable of the three original sites identified due to inclement
weather exposure that occurs on the face of T46.
It should be noted also that this revised scope would not repair all damage of the Pier 28
fender system. As originally expected, these repairs would extend the life of the existing
system five to ten years. Staff expects the fender system will still require full
replacement or upgrade beyond 5 years, based on the current condition assessment,
continued deterioration of timber piles and level of vessel layberth activity.
STRATEGIC OBJECTIVES: 
This work, if authorized, is aligned with the Industrial Moorage Initiative as it is
intended to preserve and expand berth facilities in the harbor to provide for a vibrant
Seaport that adequately serves the requirements of all essential sectors of the
maritime community.
Best management practices will be deployed in selection of materials, work practices
and ongoing total cost of ownership.

BUSINESS PLAN OBJECTIVES: 
Completion of this work will provide up to 1,100' of usable barge layberth moorage in
time for the cruise activation in 2010.

Project Cost Breakdown 
Design and Permitting                                     $60,000
Construction                                          $240,000
Total                                                $300,000
Source of Funds
This project is included in the 2009 Operating Budget in the amount of $250,000. Due to
subsequent changes in the construction schedule, the 2009 portion of project costs are
expected to be $283,000. Actual 2009 costs in excess of the budgeted $250,000 will create an
unfavorable expense variance.
This project will be funded from the general fund.

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1: Do nothing. Complete no further work on the layberth improvements.
With the displacement of barge layberth space at T91 during periods of overlap between
the cruise and fishing industry seasons, the Port would not have adequate barge layberth
space for current and future tenants. For these reasons, Alternative 1 is not
recommended.
Alternative 2: Repair and improve the three originally proposed facilities at T-25, P-28
and T-46, and the two additional piles at the NE face of Terminal 46. This would require
additional funding authorization. For this reason, Alternative 2 is not recommended.
Alternative 3: Concentrate remaining improvement e fforts at the Pier 28 site, and include
two piles at the NE face of Terminal 46 to address most pressing potential operational
and safety requirements, and accommodate current barge layberth moorage demand.
This is the recommended alternative. 
OTHER INFORMATION: 
The Seaport's harbor has been constrained seasonally from meeting the berthing
requirements of some maritime sectors, forcing vessels to berth elsewhere in Puget Sound
at additional cost and creating additional vessel emissions in the process. Moreover, it
makes for a less efficient harbor for our customers, large and small. The advent of
TWIC, in February 2009 has placed additional capacity constraints on the Seaport's
moorage capacity. Repositioning cruise from T30 to T91 will further displace moorage
available in our harbor.
