Program Objective & Scope
Increase passenger, employee & freight mobility
and convenience
Increase system reliability and availability
Bring all vertical transportation up to latest
technology
Renew and replace equipment that is beyond its
service life
Implement a comprehensive and systematic
renewal and replacement program
Ensure the integrity and continuity of operations
and systems
Enhance operational reliability
Lower on-going operational costs
3

Sea-Tac Vertical Transportation
Equipment Issues
Aging equipment requires more maintenance
Parts become obsolete and hard to obtain
Technological obsolescence
Longer downtimes
More disruptions to operations
Aging equipment presents reliability concerns
Increasing passenger traffic places increasing
loads/demands on the equipment
Service Life Factor:
Equipment age/expected service life (25 yrs)

4

Equipment Service Life Factors

Number of elevators and escalators with a
service life factor greater than 1.0
(expected service life is 25 years)
32 elevators  39.5% of total
48 escalators  60.8% of total



5

Corrective Maintenance Cost Trend




2009 Costs are prorated from the first 5
months actual costs.

Projects In Process
Seven Garage Elevators
"A" Bank    Upgrade includes:
P18    Solid state drive
P19    Solid state logic
P20    Fireman's service phase I & II
Seismic restraints for guide
P21    rails, machines & controllers
P22    Central monitoring

Six Garage Escalators
Code Improvements    9

Projects In Process

Replacement of 42 Escalators
Severed drive shafts prompted a survey of all
the escalators at SeaTac.
This survey identified 42 escalators that are
of equivalent age and construction.
The survey also found several escalators
needing emergency repairs to prevent
similar failures.
