SUBJECT:  Baggage Optimization Capacity Acceleration (CIP #C800612) 
Amount of this request:                 $637,000 
Total estimated project cost:        $445,050,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) authorize additional design 
and project management funds to expand the capacity of the baggage system at Seattle-
Tacoma International Airport to 60 million annual passengers (MAP); (2) use Port crews and
small works contracts to perform additional construction work; and (3)   amend Service
Agreement P-00317641 to add $10,160,000 for a total contract value of $31,160,000 to design
this additional capacity. The amount of this request is $637,000. 
EXECUTIVE SUMMARY 
This request is to incorporate a future capacity expansion of the Baggage Optimization project
now in order for the new outbound baggage system to accommodate 60 Million Annual
Passengers (MAP). The Baggage Optimization project was scoped in 2012 to accommodate 45
MAP with an expandable design to accommodate future growth. At the time, growth forecasts 
were flat and predicted 45 MAP would be adequate through 2027. The decision was made to
proceed in building an expandable 45 MAP system with the expectation that an expansion
would occur in the future in time to accommodate growth up to the 60 MAP level. Due to
unprecedented growth at the airport, the 45 MAP threshold was met in 2016, over ten years
earlier than anticipated. 
The cost associated with the Requested Action is $24,937,000. The project returned savings in
April 2017 in the amount of $24,300,000 (due to favorable Phase 1 Construction bids), which
will offset this request so that the total amount of this authorization request at this time is
$637,000. 
By designing and building the system to accommodate 60 MAP the Port can be assured that the
existing terminal will have enough baggage screening capacity until new facilities can be

brought online pursuant to what is currently being advanced in the Sustainable Airport Master
Plan (SAMP). The 60 MAP baggage system will have the ability to potentially tie into a new
passenger terminal in the future. To meet near and long term baggage demand for the airport,
we are currently requesting to incorporate the planned expansion at this time. The nature of
baggage systems does not allow for small incremental capacity additions, therefore this request
is to build the system to its full capacity of 60 MAP.
This request seeks authority to increase the amount of design funding in order to accommodate
a baggage system capacity expansion, to amend a baggage consultant agreement to include
this additional capacity design, and to make equipment purchases and perform preliminary
enabling work to clear areas and speed up the coming contractor activities in future phases. 
This baggage system capacity acceleration would achieve the following outcomes: 
Increased outbound system capacity to 60 MAP 
Increased system redundancy and, therefore, increased system availability 
JUSTIFICATION 
One of the main objectives of the Baggage Optimization project has been to design and build a
system that can be efficiently expanded to 60 MAP in the future. While the current scope is to
build a system capable of servicing 45 MAP, the system was designed with future growth and
expansion in mind. 
After experiencing multiple years of compounding higher than projected passenger growth,
initiating the expansion previously expected in the future will minimize service disruptions to
airlines and passengers. Authorization at this time will allow the expansion to be efficiently
incorporated into Phase 2 and Phase 3, with no rework required to the Phase 1 scope currently
under construction. 
The airlines have been briefed about the proposed capacity expansion at the last five
Airline/Airport Affairs Committee (AAAC) meetings, and are aware that it will be on the next
Majority in Interest (MII) ballot for the amount of $150M. 
DETAILS 
The authorizations requested and actual project costs associated with this request are to: 
Authorize $19,937,200 additional design and project management funds to expand the
capacity of the baggage system to 60 MAP 
Authorize $5,000,000 to utilize Port crews and small works contracts to perform
additional construction work 
Authorization for these two items totals $24,937,200. 
The Port has contracted with BNP Associates for design of the baggage optimization
project. It is necessary to amend this contract to add an additional $10,160,000 for
design and construction support thru 2024. This Service Agreement P-00317641

increase is within Commission authorized project spending. In accordance with RCW
53.19, the Commission is notified that this amendment exceeds 50 percent value of the
original contract and this memorandum will be made available for public inspection. 
The total (all phases combined) project schedule would be extended 14 months and
total cost is estimated at $445,050,000. 
Scope of Work 
The requested capacity acceleration will include the following additions in order to expand the
capacity of the baggage system to 60 MAP: 
1)  Installation of additional CTX Machines (TSA provided) 
2)  Ticketing mainlines 
3)  Sortation mainlines 
4)  Additional recirculation lines 
5)  Building infrastructure to accommodate additional BHS capacity 
6)  Additional baggage inspection tables in Central Screening Area 
7)  Additional conveyor queues in Central Screening Area 
8)  Two South Satellite make-up devices and associated sortation lines 
9)  South Satellite tunnel make-up feed line addition 
10) Two new outbound make-up devices in International Arrivals Facility (IAF) and mainlines 
11) IAF manual encode station 
12) Necessary demolition of temporary IAF baggage system to allow this work to be
installed 
Much of the 60 MAP scope can be performed concurrently with the original Phase 2 and 3 
work, but portions cannot be done concurrently and will add 14 months to the total project
duration. 
The additional makeup units included in the 60 MAP scope (2 units in the new IAF and 2 units at
South Satellite) maximize the amount of makeup units that will fit within the current airport
footprint. Even with these additional makeup units the system will still have a shortage of 27
cart positions and would function more efficiently if these cart positions could be added in the
future, either by utilizing space created by future footprint expansion or potentially adding an
early bag storage facility. 
The following work has been designated for Port Construction Services to perform in order to
streamline the transition between Phases. This streamlining is not necessitated by the capacity 
expansion and will be necessary for either 45 or 60 MAP construction. This "pre-work" will
consist of the following items: 
1)  H-line wall code compliance for Phase 2 permit 
2)  Claim 13 conveyor input installation 
3)  Right of way clearances

4)  Right of way conveyor, MCP and conduit demolition 
5)  Change order alternative 
6)  Portering of bags to maintain operations during construction 
7)  Shutdown support 
8)  Equipment movement and TSA/contractor support 
9)  Tenant, TSA, Airline and Port move support

increased capacity scope at the end of the project as a fourth phase. 
Cost Implications: $180,000,000 
Pros: 
(1)   Bid and construction of Phases 2 and 3 would continue as originally anticipated, while
designing and bidding the increased capacity would be added as an additional project
phase. 
Cons: 
(1)   Overall costs will be higher as it is more efficient to construct the expanded design
concurrently with Phases 2 and 3. 
(2)   The reliability of service for the airlines and travelers will be compromised until this
scope of work is completed. 
(3)   Fourth phase would extend current project schedule 2-1/2 years. 
This is not the recommended alternative. 
Alternative 3  Authorize increased scope of the Baggage Optimization project in order for the
new outbound baggage system to accommodate 60 MAP. 
Cost Implications: $150,000,000 
Pros: 
(1)   This will allow the new baggage system to meet airport growth. 
(2)   Results a cost savings versus designing and performing this work in the future due to
efficiencies gained by combining work with existing phases. 
(3)   Reduction in cost escalation compared to performing this work in the future. 
Cons: 
(1)   Increases the complexity of Phase 2 and Phase 3 construction. 
(2)   Adds 14 months to project versus original 45 MAP schedule.

ADDITIONAL BACKGROUND 
Baggage Optimization Project Update: 
The Baggage Optimization project increases the screening capacity of the Baggage Handling
System to process growing baggage volumes, increases flexibility to allow bags to be checked in
anywhere in ticketing and be conveyed to any makeup device, meets a minimum-connect-time
goal, and increases energy efficiency.  Meeting travelers'  baggage needs will significantly
contribute to increased customer service. 
This project will be constructed in three phases.  Project Phase 1 construction contract was
executed in March 2017 and notice to proceed is expected to be granted in May 2017. 
Phase 1 construction was advertised and bids were opened in Q4 2016. Three bids were
received; the lowest bidder was PCL Construction Services Inc. with a bid amount of $52M.
The bid amount was $28M below the Engineer's Estimate of $80M. The project returned $24M
due to the low bid. 
Pre-work began in December 2016 with Port Construction Services crews and small works
electrical contractors. A new makeup unit has been installed. Horizon moved their operations
to this new device in April 2017. The PCS crews are now working to complete a new odd-size
device, from which TSA will begin to operate at the end of June 2017. 
Small business requirements were also evaluated and set for the Phase 1 construction contract.
The requirement for this contract is that 15% of the total contract value, including change
orders, be performed by Small Business Enterprise(s). Within the 15% total requirement, at
least 5% of the total contract value work shall be performed by one or more Certified Small
Businesses.
