ACTION ITEM             Date of Meeting Date of Meeting    November 8, 2011 
DATE:    October 27, 2011 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    Rees Robinson, Project Manager, Marine Maintenance 
SUBJECT: Request for Funding Increase for the P69 Cooling Tower Replacement (Project #104505,
CIP C800359) 
Amount of This Request: $65,000       Source of Funds: Tax Levy 
Total Project Cost:     $340,000       State and Local Taxes Paid: $18,300 
No. of Jobs Created:    6 
ACTION REQUESTED:
Request Commission authorization for the Pier 69 Cooling Tower Replacement Project and for
additional funding to complete construction of the project at an additional cost of $65,000 for a total
project cost of $340,000. Additional funds for the project (Project #104505, CIP #C800359) are
available due to under-spending in other Real Estate projects. 
SYNOPSIS: 
The existing P69 cooling tower was installed during the building renovation in 1992. The cooling tower
is at the end of a typical service life of twenty years for a cooling tower. Additionally, the cooling tower
is on the roof of P69, placing it in a corrosive marine environment. This potentially reduces its expected
life.
The project is currently budgeted in the 2011 Real Estate Small Project CIP C800359. The authorized
budget for the cooling tower replacement project is $275,000. The authorized project cost was
estimated prior to engineering design and was based on a rough order of magnitude construction cost
determined in 2007. Subsequently, in-house engineering completed design, and the contractor was given
construction documents to provide an estimate for the work. The project cannot be completed within the
authorized budget. Port staff are requesting an additional $65,000 to complete the project. 
ADDITIONAL BACKGROUND: 
Performance of the cooling tower is essential to building operations. The tower serves all of the chillers
that provide cooling to the P69 building. Replacement of the P69 Cooling Tower has been identified as a
future small capital project since 2007.

Cooling tower replacement was included as a planned project in the Real Estate 2010 Small Project CIP
C800305. Since work did not begin on the project until 2011, the project moved to the Real Estate 2011
Small Project CIP C800359. 
During acquisition planning for this project, we decided to use in-house engineering for design and to
use an HVAC on-call small construction contract with Port electrician support for installation. Design is
complete and the on-call HVAC construction contract has been executed. 
The original project budget was based on a rough order of magnitude construction cost estimate of
$118,000. The preliminary estimate was provided by the chiller maintenance service provider in 2007, 
prior to any preliminary design. Following design completion, Port engineers provided a construction
cost estimate of $189,000. The contractor's not-to-exceed cost estimate for their portion of the work is
$192,000. 
PROJECT JUSTIFICATION: 
The P69 cooling tower is at the end of its service life. If it is not replaced before the spring of 2012, the
Port runs the risk of not being able to cool the building.  The inability to cool the building would result
in unacceptable indoor air quality as well as damage to data center and electrical service equipment. 
PROJECT SCHEDULE: 
Port Engineering has completed design. Construction is expected to occur in the first quarter of 2012.

Source of Funds: 
This project was included in the 2011 Plan of Finance under the Real Estate 2011 Small Project CIP
C800359 in the amount of $275,000. The additional $65,000 which is required to fund this project is
available due to lower than anticipated spending on other 2011 Plan of Finance committed projects such
as Real Estate technology projects.
This project will be funded by the Tax Levy.

ALTERNATIVES CONSIDERED/RECOMMENDED ACTION: 
Alternative 1: Do not replace the cooling tower. The cooling tower will eventually break down causing 
unacceptable indoor air quality as well as damage to data center and electrical service equipment.This is
not the recommended alternative. 
Alternative 2: Continue with the planned P69 Cooling Tower Replacement Project. Authorization of an
additional $65,000 for a total project authorization of $340,000 will allow replacement of the cooling
tower before the next warm weather season. This is the recommended alternative.
