EXECUTIVE SUMMARY 
Communication rooms at Seattle-Tacoma International Airport (STIA) house telecommunications
and data processing equipment that are critical for airport operations.  The Port of Seattle
updated the security requirements for communications rooms and a subsequent security audit
identified deficiencies in communications rooms in need of correction. This project will bring all
STIA terminal communications rooms up to the latest Port of Seattle security standards by
installing (details intentionally omitted) enhanced security measures.
JUSTIFICATION 
This project is designed to comply with findings from an internal audit of the communication
rooms at STIA. The locations were identified in the audit, several have since been updated as
part of other projects, the remaining rooms will be addressed with this project. These sensitive
rooms contain vital communication equipment and cable interconnection infrastructure. The
findings from the audit revealed the requirement for increased security and access control for

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 – Do not proceed with the project. 
Cost Implications:   Expense approximately $700,000 for Notebook and Design development
costs. 
Pros: 
(1)   Delays or defers capital investment. 
Cons: 
(1)   Audit findings remain unaddressed. 
(2)   Security of the communication rooms remain at current levels with no reduction in risk 
of unauthorized access. 
(3)   Change in software/hardware may happen during deferment. 
(4)   Potential for additional increase in costs for materials, labor, and/or inflation. … 
This is not the recommended alternative. 
Alternative 2 – Comply with Audit and secure STIA communication rooms. 
Cost Implications: $8,100,000 in capital cost. 
Pros: 
(1)   Complies with the Audit and brings the security access of these highly sensitive rooms
to current Port standards. 
(2)   Reduces the potential risk of unauthorized access onto critical STIA networks. 
(3)   Provides the owners of these rooms the ability to remotely monitor room and door
status. 
(4)   Provides better flexibility to control who has access to these very sensitive rooms. 
Cons: 
(1)   Capital Cost. 
This is the recommended alternative.
