ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to advertise for bids, award,
and execute a major works construction contract to repair the Pier 69 roof beams for an estimated
cost of $2,694,000, bringing the total authorization to $3,024,000. 
SYNOPSIS 
The header beams that support vertical window frames within the Pier 69 sawtooth roof continue
to exhibit occasional concrete spalling (small pieces breaking loose). A design has been
developed to perform preventive maintenance measures, stabilize the window frames, and
protect occupants from the potential hazard of future spalling. 
BACKGROUND 
The interior roof beam surfaces have exhibited occasional concrete spalling since the Port
occupied the building in 1993. Maintenance measures have been ongoing, including visual
inspections and removal of loose concrete.  However, recent inspections have indicated that
rebar corrosion in the 85-year-old beams will continue to pose a risk of concrete spalling with the
related risk to occupants. The inspections also revealed that the clerestory window frames were
improperly installed and require stabilizing. 
KPFF conducted an investigation and provided a report dated May 15, 2014, summarizing their
observations and outlining a preliminary list of  recommended repairs. Recommendations
included preventive maintenance measures to preserve the roof beam structure, the installation of
new bracing to stabilize the clerestory window frames, and installation of removable metal mesh
beam covers that will facilitate visual inspection of the beams while protecting occupants from
potential concrete spalling.

Following 60% design, a hands-on inspection was performed by KPFF on April 23, 2015, to
provide a further  basis for repair types and quantities  required for the project. Marine
Maintenance performed a demonstration of the repair in the conference center lobby to test the
design concept and visual appearance. A Lessons Learned meeting was held afterwards to
identify key considerations to carry forward into 90% design. 
The design documents are now complete and we are ready to move to the construction phase of
the project. 
PROJECT JUSTIFICATION AND DETAILS 
This project has been approved as part of the CIP budget #C800689. On July 1, 2014, the
commission authorized $330,000 for the project design phase. The overall project estimate range
determined at that time was from $2,300,000 to $3,300,000. 
All construction activities will take place  during non-office hours, and the work will be
conducted in five (5) phases to reduce operational impacts to the office area. Due to the number
of phases and other restrictions, the overall timeline of the project has been estimated at 300
calendar days, or approximately ten (10) months from contract execution to physical completion.
The project team will keep occupants informed of operational impacts throughout construction. 
Project Objectives 
Ensure continuity of operations for the Pier 69 facility. 
Protect occupants from concrete spalling. 
Provide preventive maintenance treatments for the concrete beams that will facilitate
future inspections. 
Stabilize clerestory window frames. 
Scope of Work 
Condition assessment of the roof beams. 
Concrete spall repairs, to include epoxy injection of concrete cracks. 
Installation of protective metal mesh covers. 
Installation of stabilizing braces for clerestory window frames. 
Schedule 
Advertisement - November 2015. 
Notice to Proceed Q1 2016. 
Physical completion Q4 2016.

Budget Status and Source of Funds 
This project was included in the 2015 Approved Capital Budget and related Plan of Finance as
Committed-Authorized CIP #C800698 in the amount of $2,310,000. The additional funds
required in the amount of $714,000 are available due to underutilization of funds in other
projects such as preliminary planning and technology projects. Since Pier 69 is the corporate
headquarters for the Port, the funding for the project is allocated between the General Fund for
Maritime (27.08%) and Economic Development (8.33%) and the Airport Development fund
(64.58%).

TRIPLE BOTTOM LINE 
Economic Development 
Economic benefits include the prevention of future operational interruptions and the related costs
of emergency repairs, and preservation of the value of the Pier 69 facility. 
Activities at Pier 69 will be minimally impacted during the project. 
Environmental Responsibility 
Contract provisions require the contractor to contain demolition activities and to perform 
regulated materials work with adequate protection in accordance with regulatory requirements.
The Port will perform secondary testing in the office space during the project to ensure the
Contractor's containment system is functioning properly and that indoor air quality remains safe
and suitable for occupants. 
Community Benefits 
Performing the project in accordance with the schedule will preserve use of the building and
second floor atrium for holiday and other common uses for the public and Port staff. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Do not perform repairs. 
PROS 
A $2,694,000 short-term cost savings. 
CONS: 
Increased risk of injury to building occupants due to concrete spalling. 
Increased hands-on inspections by  Marine Maintenance at regular intervals to
mitigate risks. 
Access for maintenance and inspection will remain difficult and will likely need to be
contracted, generating significant costs. 
Temporary relocation of staff may be necessary if spalling occurs. 
Clerestory windows will remain unbraced at many locations. Without installation of
bracing, frames will continue to deflect during high winds resulting in window
breakage. 
Decreased value of the Pier 69 facility. 
Alternative 2)  Perform proposed repairs to protect occupants and ensure continued use of the
Pier 69 facility. 
PROS 
Risks of occupant injury will be reduced.

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer 
October 20, 2015 
Page 5 of 5 
Clerestory window frames will be properly braced and risks of future window
breakage will be reduced. 
The value of the Pier 69 facility will be preserved. 
CONS 
The expense of $2,694,000 and the related increase in depreciation. 
Construction related activities, include scaffolding, will be an inconvenience to some
occupants. 
This is the recommended alternative.
