SUBJECT:  Access Control in Communication Rooms (CIP# C800935) – Design Authorization 
Amount of this request:              $ 2,000,000 
Total estimated project cost:          $ 8,100,000 

ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) increase the project budget
by $5,207,000 for a revised total budget of $8,100,000; (2) prepare design and construction bid
documents for the Access Control in Communication Rooms project; (3) Utilize Port of Seattle
crews and small works contracts for pre-construction work; (4) procurement of long-lead owner
furnished equipment to include network switches, interface terminal boxes (ITB), and main
headend gear. The amount of this request is $2,000,000 for an estimated total project cost not
to exceed $8,100,000.
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.
When developing the preliminary budget for this project it was assumed core  security
infrastructure capacity was available and that the project could be completed at a relatively low
cost. Through preliminary design and field investigation completed this year, it was determined
that  substantial  additional  security  infrastructure  (local  power  supplies,  new  head  end
equipment and interface terminal boxes) would be required at each communications room. As
a result of the additional scope, project delays due to the Coronavirus disruption, rising material
costs, increased labor rates, and escalation  the project team is requesting an additional
$5,207,000 for a total revised budget of $8,100,000.

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 
these rooms. Existing key or cipher lock access does not meet the latest heightened security
requirements and access controls. The scope of this project will increase security measures to
meet current Port standards.
Diversity in Contracting 
The design services will be completed using an existing IDIQ contract that was established in 2022 
which has a 17% WMBE participation utilization goal.
DETAILS 
Scope of Work
For security purposes, key details of the Access Control in Communication Room project have
been intentionally omitted:
(1)   Design  services  will  evaluate  the  internal  audit-identified  Communication  rooms
needing access control devices, associated wiring, and infrastructure equipment.
(2)   Design  services  will  provide  communication  and  electrical  drawings  required  for
installing new access control devices, wiring, associated infrastructure equipment and
connection to existing STIA networks. 
(3)   Construction services:
a.  Modify room walls to accommodate infrastructure equipment
b.  Modify walls around door to accommodate access control devices 
c.   Modify doors as required 
d.  Install associated wiring and interconnections for access control devices 
e.  Installation of infrastructure equipment, access control devices, and surveillance
equipment.
f.   Connection to current STIA Access Control System and surveillance system 
g.   Set-up and removal of barricades for securing the rooms during construction

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1 –Status Quo. Do not proceed with project.
Cost Implications: Expense approximately $75,000 for notebook 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 sensitive rooms to
current Port standards.
(2)   Reduces the potential risk for 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 highly sensitive rooms.
Cons:
(1)   Capital Cost 
This is the recommended alternative.
