SUBJECT:  Terminal 91, C-175 Building Roof Replacement - Design 
(CIP# C800430) 
Amount of This Request:  $190,000        Source of Funds: General Fund 
Total Estimated Project Cost:  $2,445,000 
ACTION REQUESTED:
Request authorization for the Chief Executive Officer to proceed with executing service
agreements, preparations of construction documents, project management and permitting tasks
for the design phase of Terminal 91, C-175 Building Roof Replacement Project. The amount of
this request is $190,000, bringing the current authorization for the project to $240,000 for a total
estimated project cost of $2,445,000.
SYNOPSIS:
CityIce Cold Storage, LLC, (CityIce), is the tenant of the C-175 Building at Pier 90 and operates
a cold storage operation in the building. The building lease with CityIce expires in 2039 and has
options for two additional 10 year extensions. In accordance with the terms of the lease, the Port
has responsibility for the replacement of the 90,000 square foot roof. The building was built in
the early 1990's and is in good condition. The roof is approximately 18 years old, has performed
well during this time period and is currently not leaking but is nearing the end of its 20 year
design life.
Two roof inspections have been performed on the building. The first in November 2009 was
sponsored by the tenant and the second inspection in February 2010 was sponsored by the Port.
Both the reports from the inspections have similar findings. The reports indicate the roof is
beginning to show signs of deterioration with membrane shrinkage, tenting, and uplift during
strong winds. Both reports recommend replacement of the roof. The tenant sponsored report 
states replacement should occur in two to three years (2011 to 2013) and the time frame in the 
Port-sponsored report is two to four (2012 to 2014).

BACKGROUND: 
While minor leaks can be repaired with increased maintenance, the major concern is if large
sections of the roof membrane are damaged during wind storms. Should this occur, the building
and contents would be exposed to the elements disrupting tenant operations and requiring
emergency repairs. As the roof ages, the roof membrane will continue to deteriorate increasing
the likelihood of a major failure. With the building located on a pier, the risk of damage due to
higher open-water wind exposure also increases. 
Additionally, the white coating applied to the black membrane has failed in many areas on the
roof. While the failure of the coating does not affect the waterproof integrity of the system, it
does increase the thermal adsorption of the building. Replacing the reflective coating with a new
roofing system will restore the building to the initial energy efficiency. 
This project will remove and replace the existing roof membrane and related roofing elements.
This authorization request of $190,000 is for the design development phase of the project. The
design is scheduled to be completed in March 2012. During the design phase, different roofing
system alternatives will be evaluated to determine which system has lowest cost of ownership.
The roofing alternatives include: membrane, built-up and metal with design lives ranging from
20 to upwards of 45 years. 
The planning level estimated cost range of the project, including future construction
authorizations is between $1,864,000 and $ 2,445,000. The total estimated cost of the project
has increased from the $1.2 million shown in the 2011 Plan of Finance for the following three
reasons. Costs of $340,000 have been included to investigate and incorporate environmentally
sustainable processes and practices components. These costs were identified for this project in
the 2011 Committed CIP #C800160. Secondly, a more detailed cost estimating process was
utilized increasing the direct and indirect construction costs by roughly $300,000. Thirdly, the
initial estimate was for a roof system with a 20 year design life, an additional $600,000 has been
included in the estimate range for roofing systems with a longer design life that more closely
matches the length of the lease. Additional analysis will be performed during the design process
to determine if the longer design life will provide the lowest cost of ownership to the Port.
Ultimately the roofing system with the lowest total cost of ownership will be selected. 
In addition to the removal and replacement of the roofing system, the project provides an
opportunity to investigate and implement environmentally sustainable practices and processes as
part of the new roof systems. As the design develops, environmentally sustainable options will
be evaluated utilizing criteria identified in EX-15, that include total cost of ownership,
environmentally-sustainable development, conservation of resources and possible grant
reimbursement as a method of determining which sustainable elements will be included in the
final project. Potential sustainable elements may include; rainwater harvesting, passive solar
system, reduction in roof heat adsorption, and wind generation.

Port staff will consult with the Office of Social Responsibility to determine what opportunities
exist for small business on the project. Where opportunities exist, small business participation
will be encouraged. 
PROJECT JUSTIFICATION:
As the roof membrane is near the end of its service life, replacing the roofing system now will
avoid costs for future repairs and potential water damage to the building insulation, structural
elements and tenant operations. The lease agreement between the Port and CityIce has the
maintenance and repair of the roof as an obligation of the Port.

ENVIRONMENTAL SUSTAINABILITY AND COMMUNITY BENEFITS: 
No negative environmental impact is anticipated as a result of this project. However, the
roofing project does provide an opportunity to investigate and include environmentallysustainable
construction practices and processes and has funding from the Green Port
Initiative budgeted for this purpose. 
The initiative money will be used to investigate and implement environmentally sustainable
components and/or processes that are above and beyond what would be considered standard
construction practices and processes and in compliance with EX-15 and CPO-2.
The development and analysis of viable options will occur during the design process and may
include; rainwater harvesting, passive solar system, reduction in roof heat adsorption, and
wind generation. 
TRIPLE BOTTOM LINE: 
Replacing the roof maintains a Port facility supports the commercial fishing industry at Pier 90.
The project will not have any adverse impacts not the environment and will incorporate
environmentally-sustainable building practices and processes where feasible.
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1: Do nothing. T he roof is currently functioning; replace the roof system after it
leaks or fails. The risk of waiting until the roof leaks or fails is that emergency repairs would
need to be performed during the period when the new roofing system is being designed and bid,
potentially increasing the costs. Damage to the insulation and roof support structure could also
occur increasing the replacement cost as well as having the potential of disrupting the tenant
operations. 
Alternative 2: Proceed with the design and complete it by the spring of 2012.  Delay the
replacement for one to two years to extend the existing service. During this time period , perform
additional monitoring and spot repairs as needed. The risk of selecting this alternative is
twofold. The first is the combination of increased costs for inspection and maintenance and
unknown escalation costs of construction may exceed the savings gained by the extended service
live of the existing roof. The second risk is design may no longer be valid and would need to be
redone in part to address any potential changes in the building code or materials. 
Alternative 3: Proceeding with the design and replacement of the roof system now will reduce
future risks of a major roofing system failure, restore the energy efficiency of the roof and reduce 
the risk of emergency repair costs. This is the recommended alternative.
