AGENDA MEMORANDUM                        Item No.          8e 
ACTION ITEM                            Date of Meeting       April 12, 2022 
DATE:     April 4, 2022 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Eileen Francisco, Interim Director - Aviation Facilities and Capital Programs 
Wayne Grotheer, Director - Aviation Project Management Group 
SUBJECT:  Concourse C Temporary Air Handling Units (CIP#801149) 
Amount of this request:               $1,000,000 
Total estimated project cost:          $2,980,000 
Request Commission authorization for the Executive Director to (1) increase the project budget
for the Concourse C Temporary Air Handling Units project in the amount of $1,000,000; (2)
prepare, advertise, and execute a major works construction contract; and (3) use Port crews
and small works contracts to assist with the project. The total estimated cost of this project is
The existing Air Handling Units (AHUs) on Concourse C are at maximum capacity and are no
longer able to meet current demands. Additional air is needed for tenant buildouts of
additional Airport Dining and Retail (ADR) spaces and new restrooms. Two additional AHUs will
be added on the roof of Concourse C to provide additional air until a planned future project will
upsize all the existing AHUs on Concourse C. These temporary units are needed now to meet
existing lease agreements with tenants and to support the new restrooms that are currently
under construction. As the project progressed with design, it identified the need for additional
funding because of current market conditions and increased material costs, specifically in the
piping and AHUs. 
Three ADR leases have been signed to replace a single existing restaurant space. The new leases
consist of two restaurants and a retail space which requires additional air capacity as compared
to the previous single restaurant. The restrooms on Concourse C are being replaced to provide
better passenger experience and are increasing the turnover rate of air in the restrooms from
eight times per hour to twenty times per hour. These modifications exceed the existing
system's capacity. Restrooms in public buildings typically require ten to twelve times per hour

air change rate for standard use, so a higher turnover rate for the Concourse C restrooms will
maintain fresh air and lower odors for the improved passenger experience. 
Adding the two temporary units will provide the additional capacity for the next five to ten
years until the future project to upgrade all the air handlers, including the addition of smoke
control, can be completed. This larger project will also replace and upgrade all the AHUs on
Concourses B and D which are at the end of useful life. 
Multiple cost drivers regarding materials have increased the budget need. These additional
materials include HVAC components, seismic upgrades, roofing costs, chill water piping and
piping costs, and an increase in the cost of demolition. Both the air handling units and
associated piping have doubled in cost in the last 18 months. Lastly, a 10% market contingency
was added based on current conditions. In total, the construction bid estimate will increase by
around $1 million. 
Diversity in Contracting 
The project team with the Diversity in Contracting Department determined a six percent
aspirational goal for WMBE participation for the major works construction contract. 
This project installs two new energy efficient AHUs to provide additional air capacity to
Concourse C to improve passenger experience. 
Scope of Work 
The project requires additional air capacity in two zones at Concourse C. To accomplish the
(1)   Two, 4,900 CFM AHUs will be installed on the roof of Concourse C and have heating
and chilled water connected from the campus systems, along with direct digital
controls wiring for control and monitoring of the equipment. A major public works
construction project will be used to perform the work.

Alternative 1  Defer the project 
Cost Implications: Approximately $200,000 would need to be expensed. 
(1)   No capital investment. 
(1)   Does not provide the needed air for new restrooms currently under construction. 
(2)   Does not provide the needed air for ADR spaces that are currently leased and soon to
be constructed. 
This is not the recommended alternative. 
Alternative 2  Approve the increased budget. 
Cost Implications: $3,000,000 
(1)   Provides the air required for restrooms and ADR spaces. 
(1)   Highest capital investment. 
This is the recommended alternative.
