Operating Expense Budget and will result in a negative variance in 2011. T he 2012 Operating
Expense Budget contemplates expenditures consistent with this Request.
PROJECT JUSTIFICATION: 
The Pilot Project will undertake repair and maintenance affecting approximately 270 linear feet 
on up to four (4) existing cast-in-place pile cap beams at Terminal 18 as a means of providing
practical guidance to: 
1.  Understand the extent and rate of deterioration of pile caps within our pier structures; 
2.  Analyze site conditions and more precisely determine when further repairs are required; 
3.  Prepare specific design documents and detailed project specifications on future scopes of
work; 
4.  Identify means to reduce risk to the Port associated with overly conservative or overly
aggressive bids on similar future Major Works contracts;

PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
The repair and maintenance scope of work includes repairing up to four (4) pile caps at T-18.
The Pilot Project's sample is representative of conditions identified on other pile caps, and
selected alternative repair techniques will be performed to gain field experience with each, which
will be useful when preparing to undertake future, larger, scopes of work to repair and maintain
pile caps at T-18 and other marine terminals. Alternative repair techniques may include any or
each of the following: 
Removal of cracked and corrosive concrete from the lower portion of the pile caps 
Cleaning the exposed concrete surface 
Abatement of corrosion to existing reinforcing steel 
Application of bonding agent to existing concrete 
Casting or shotcrete application of new concrete or mortar 
Epoxy injection

Source of Funds 
The T-18 Pilot Pile Cap Repair Project was not anticipated in the 2011 Operating Expense
Budget. The design and permitting efforts for this project are expected to be completed in 2011
for approximately $100,000 and will create an unfavorable expense variance. This 2011
variance in the Seaport Division has been offset by increased revenue and through expense
reductions in other areas. 
Based on the May 24, 2011 Commission action approving $300,000 for design and permitting of
this project, the funding to complete construction on the T-18 pile cap pilot project has been
included in the proposed 2012 Operating Expense Budget in the amount of $700,000. Due to
timing differences in project spending, the current estimated project costs for 2012 is $900,000,
which will create an unfavorable operating expense variance of 200,000 in 2012. The Seaport
Division will again work to find offsets to this unfavorable variance through either increased
revenue or through expense reductions in other areas. There is no anticipated unfavorable
variance in the overall project cost of $1,000,000. 
This project will be funded from the General Fund.

ECONOMIC IMPACTS AND BUSINESS PLAN OBJECTIVES: 
Proceeding with the construction phase of the Pilot Project will ensure continued use of the
repaired pile cap portions of the terminal by the tenant and preserve existing revenues for the
port. 
STRATEGIC OBJECTIVES: 
This project supports Seaport Economic Vitality by analyzing and evaluating the service-life
requirements of aging infrastructure assets and implementing repair and maintenance solutions in
a cost-effective manner, while minimizing and avoiding potential disruption of tenant cargo
operations. 
ENVIRONMENTAL SUSTAINABILITY AND COMMUNITY BENEFITS: 
Project construction will include practices to avoid and minimize potential negative
environmental effects. The pilot project will identify repair and maintenance methods,
materials, and practices for effective under-pier work while avoiding release of deleterious
materials to the environment and reducing the potential for adverse effects on aquatic area
natural resource values. 
Timely repair and maintenance extends the service life of existing infrastructure, as an
alternative for avoiding more environmentally disruptive and resource/materials consumptive
large scale structure replacement actions. 
TRIPLE BOTTOM LINE: 
Extending the useful service life of our existing assets defers eventual replacement costs for a
longer period of time, supporting the economic vitality of our operations.

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
1.  Conduct a pilot repair and maintenance project and use the results of design, planning and
construction experience to improve efficiency of similar projects in the future, including
cost-effectiveness, schedule, and operational impacts on working terminals. This is the
recommended alternative. 
2.  Complete major repairs without the benefit of a pilot project. This alternative would reduce a
portion of the costs associated with a stand-alone project and get the work done sooner, thus
avoiding further deterioration and more extensive repairs in the future. Key risks include:
scheduling and performing work in areas beneath existing piers in the intertidal elevations at
low tide; variable productivity rates for differing repair solutions; accurately determining the
extent of repairs based on surveys of damage; and other risks that can be better understood by
performing a pilot project. This alternative was rejected due to the high risk of unknowns for
a full-scale repair project.
3.  Monitor the pile cap distress over time and defer the cost of the pilot project and major
repairs until a later date. Further delay is likely to result in costlier repairs in the future as the
rate of deterioration in the pile caps accelerates over time. This alternative was rejected due
to higher anticipated costs, and risks of greater interruptions to terminal cargo operations.
