SUBJECT:  Baggage Optimization Phase 3 Enabling Construction Work 
Amount of this request:               $7,500,000 
Total estimated project cost:        $955,000,000 

ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) authorize an early work
construction contract for Baggage Optimization Phase 3 including construction of D1 and C94
transfer lines, (2) procure long lead items, and (3) increase the project authorization by
$7,500,000.
EXECUTIVE SUMMARY
Baggage Optimization is an airport-wide public safety and security program that improves
customer service for both airlines and passengers. This is a long-term, three-phase program that
is anticipated to be completed in 2027. The program allows the flexibility for bags to be checked
in from any ticket counter and be conveyed to serve any gate.  The project is being bid and
constructed in three separate phases.  Phase 1 has been completed, Phase 2 is under
construction, and development of Phase 3 began in Q3 2022.  Phase 2 is approximately 88%
complete and is expected to be substantially complete in Q3 2024.  Due to the lack of
interconnectivity until the project is complete, near continuous operation, and a fixed footprint,
this project has various constraints requiring detailed construction sequencing plans. A General
Construction/Construction Manager (GC/CM) was selected for Phase 3. To leverage the benefits
during the preconstruction period, procuring long lead essential conveyor material as part of
enabling work will allow for construction to stay on schedule. This request is a limited initial
request to support the procurement of long lead items, and authorize the construction for two
key pieces of work that require early action. The project will return to Commission in Q4 to
request full authorization of the program.

JUSTIFICATION
Early Work Construction Contract:
The baggage handling system is a complicated system that requires detailed and methodical
sequencing plans for minimal disruptions to airline and airport operations. Enabling construction
work packages and construction of the D1 and C94 transfer lines will allow the project to perform
work that will prepare the construction groundwork for minimal disruptions. The project team
is  working  closely  with  the  Contractor,  Airline  Technical  Representative  (ATR),  and  Port
stakeholders to develop the sequencing plans.
Procure Long Lead Items: 
Procurement of essential long lead conveyor material as part of the enabling work package is
critical to the project’s schedule. Currently the lead time for the conveyor material is upwards of
40 weeks. In collaboration with the Contractor, the long lead essential conveyor material has
been identified for the initial steps in the sequencing plan and planned for an on-time material
delivery allowing for construction to start on time.
Project Authorization Increase: 
The cost of the early work construction package including the purchase of conveyor material is
within our current budget and estimated at $7,500,000.  We are requesting authorization for
this initial request to support the procurement of long lead items, authorize the construction for
two key pieces of work that require early action, and allow for the contracting of the special
inspection firm. The project will return to Commission in Q4 to request full authorization of the
program. 
Diversity in Contracting 
Baggage Optimization Phase 3 construction contracts have a 4% Women and Minority Business
Enterprises (WMBE) goal.
DETAILS 
Scope of Work
Baggage Optimization Phase 3 will conclude the Baggage Optimization Program allowing for
complete baggage flexibility to check in any bag into any ticket counter and be delivered to any
airplane. It also accommodates passenger volume growth and meets TSA safety mandates. This
phase will tie-in all the south end systems into the centralized screening, including the
International Arrivals Facility (IAF), and finalize the sortation and ticket counter connections. 
Schedule
Phase 1 was completed in 2020. Phase 2 is currently under construction and scheduled to be
completed in Q3 2024. Phase 3 design is under way along with GC/CM preconstruction activities 
and construction is scheduled to complete in Q2 2027.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Do not proceed with approval of early work construction contract. Proceed with
approval of only the procurement of essential conveyor material that have long lead times.
Cost Implications: $4.3M for the initial purchase of long lead items.
Pros:
(1)   Procurement of essential conveyor material with long lead times allows the Port to get
into the manufacturing queue in hopes of on time delivery for construction to start. 
Cons:
(1)   Early work construction contract not being approved could cause more construction
shutdowns to be more impactful to Airline and Airport operations.
This is not the recommended alternative. 
Alternative 2 – Do not proceed with approval of purchasing of essential conveyor material with
long lead times.
Cost Implications: $4,500,000.
Pros:
(1)   No further project budget would need to be approved at this time.  Design would
continue until construction is ready to begin and full construction authorization is
needed.

Meeting Date: March 26, 2024
Cons:
(1)   A delay of 40 weeks or more waiting for essential conveyor material to arrive will delay
our construction schedule and have budget impacts. 
This is not the recommended alternative. 
Alternative 3 – Approve the request to proceed with the authorization of enabling construction
work and early work packages for Baggage Optimization Phase 3 including construction of D1 and
C94 transfer lines, procure long lead items, and increase the project authorization by $7,500,000.
Cost Implications: $7,500,000.
Pros:
(1) Authorizing the Contractor to perform enabling work allows for work to be performed in
a less impactful manner for airport and airline operations. 
(2) Authorization for the Contractor to purchase long lead items aids in ensuring the
essential conveyor material is ordered and under production for on time delivery to start
construction. 
Cons:
(1) If the project and General Contractor do not negotiate and come to terms with a
Maximum Allowable Construction Cost. The Port would have to warehouse and store the
pre-purchased material for an extended duration. The monthly charge for the warehouse
space is estimated at $30,000 per month. 
This is the recommended alternative.
