SUBJECT:  Tenant Network Demarcation (DMARC) Upgrade - C800841 
Amount of this request:        $672,000 
Total estimated project cost:     $2,815,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to prepare the design and
construction documents for the Tenant Network Demarcation project at Seattle-Tacoma
International Airport to standardize the Port's tenant communications network demarcation for
an amount not to exceed $723,000 of a total estimated project cost of $2,815,000. 
EXECUTIVE SUMMARY 
This project will standardize the Port's tenant communications network demarcation or
"DMARC packages" for existing tenants with outdated legacy communication infrastructure and
provide needed new infrastructure in vacant offices within the Airport in preparation for future
tenants. Current legacy communications infrastructure does not allow the Port to troubleshoot
and support any tenant communication challenges.
The project's scope includes communications network equipment installation in approximately
50 locations throughout the main terminal and South Satellite to (1) upgrade spaces that do not
have  communications  infrastructure  installed  or  (2)  replace  existing  outdated
telecommunications infrastructure cabling that is no longer supported by CenturyLink, which is
the lone telecommunications provider at the airport.  With a forthcoming "Meet Me Room"
capital project, the Port will be providing additional communications infrastructure to allow
multiple telecommunication service providers into the Airport so that tenants can have more
choices for the telephone, internet and cable TV services. But c urrently, if a tenant needs to
move into a space that does not have this updated communications DMARC package, it can
take several months to bring in a new service. This leaves the tenant without phone or internet
service for an extended period of time, which is not an acceptable practice or level of service
for a landlord. Once this project is complete, however, these flexible DMARC packages will

allow for quick, efficient "plug-in" portability for new or existing tenants, and provide for
expansion as technology and communications adapt and change. 
JUSTIFICATION 
Voice and internet data communications is an integral part of facility infrastructure supporting
modern business. In modern communications infrastructure, the DMARC is the point at which
the publicly switched internet/telephone network ends and connects with the customer's onpremises
wiring (the wall plugins). It is the dividing line which determines who is responsible for
installation and maintenance of wiring and equipmentcustomer/subscriber, or telephone
company/provider. 
Today we have an unacceptable level of service for new tenants: a tenant can lease an office
space, but has to wait for several months for Internet or telephone service while the legacy
systems are upgraded. Each lease agreement may require an "ad hoc project" to add required
infrastructure. This project identifies the remaining areas not already converted to modern 
telecommunications DMARCs, so in the end, all leasable tenant spaces will be on modern
communications infrastructure. 
DETAILS 
The project scope will accomplish various objectives for both the airport and tenants, such as: 
(1) Provide efficient "plug-in" portability when required by new or existing tenants 
(2) Remove existing legacy vendor equipment without disrupting any tenant connectivity 
(3) Keep the main terminal free of unsupported cabling 
(4) Eliminate service interruptions for tenant communications 
(5) Provide less cumbersome hard-wire connections for tenant communication networks 
(6) Create demarcation point between existing Port communications rooms and tenant
spaces (which will allow tenants greater choices in telephone/internet providers,
currently limited to CenturyLink) 
(7) Provide Port-managed Infrastructure which allows the quick provision of requests 
(8) Provide quick technology activation from one leased space to another as tenants
move 
Scope of Work 
(1) Design of each tenant DMARC installation package 
(2) DMARC and network equipment installation in approximately 50 locations throughout
tenant spaces in the main terminal 
(3) Targeted demolition or removal of obsolete legacy network infrastructure and
equipment 
(4) Trace existing legacy vendor cable pathways from tenant spaces that will receive a
DMARC to their source, identifying branches of legacy vendor cabling that support
other tenant spaces that do not lie within the scope

(5) Remove legacy vendor cabling from the tenant spaces identified to receive DMARC
without interrupting service to tenants 
(6) Construction of conduit and network pathways from communication rooms to tenant
lease spaces 
(7) Installation and testing of Port provided telecommunication DMARC packages 
Small Business 
Elements within the scope of work above will provide opportunities for small businesses. The
project team is partnering with the Port's small business group to outreach to interested small
and MWBE businesses of the project through the Port of Seattle's Small Business Generator
(PortGen) program efforts.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Install each tenant DMARC package as each tenant prepares to occupy space in
the airport leased properties. 
Cost Implications: $3,550,000 
Pros: 
(1) Pushes out larger portions of the capital investment into the future 
(2) Incrementally eliminates the necessity of telecommunication carriers and tenants 
from running new proprietary cabling throughout the airport 
Cons: 
(1) Ultimately costs the Port more money because of the incremental approach, negating
any efficiencies of scale, as costs are likely to increase in the future. 
(2) Follows current practice of delayed, incremental small jobs projects to install DMARC
packages in lease spaces, which require long lead times on installation of voice and
data communications, and does not meet our tenants' needs 
(3) Legacy vendor is no longer managing their legacy wiring in-house

(4) Incremental Small jobs projects will be more costly than a scheduled, planned
program of improvements 
(5) If a tenant encounters a problem, the Port can't trouble-shoot, and given legacy
vendor's decision to not manage their cable/fiber, the tenant would be in a situation
where we would likely need to do an emergency DMARC project to keep them
connected 
This is not the recommended alternative. 
Alternative 2  Install Port standard tenant telecommunication DMARC packages in vacant
areas of the airport only (leaving legacy systems with existing tenants). 
Cost Implications: $700,000 
Pros: 
(1) Eliminates the necessity of telecommunication carriers and tenant from running new
proprietary cabling throughout the airport 
(2) Provides flexibility for new tenants in new spaces to meet emerging technology
requirements which change as business opportunities expand within the airport 
(3) Provides the Port the ability to move tenants into new lease spaces quickly 
(4) Infrastructure is Port managed which allows us to quickly provision requests for new
tenants only 
(5) Ability of quick technology activation from one lease to another lease space as tenants
move to different lease spaces (assuming it doesn't involve a legacy system office) 
(6) Provides flexibility for new, non-legacy tenants to order telecommunication carrier
circuits as their data requirements change 
Cons: 
(1) Does not address outdated legacy tenant communication infrastructure; limiting their
ability to expand services and respond to changing technology needs 
(2) Does not address risk from legacy vendor communication problems and support 
(3) Requires a future project to remedy existing outdated legacy communications in
spaces as they are vacated in the future 
This is not the recommended alternative. 
Alternative 3  Install Port standard tenant telecommunication DMARC packages in 50 existing
tenant locations with outdated legacy communications and vacant tenant leased areas. 
Cost Implications: $2,815,000 
Pros: 
(1) Eliminates the necessity of telecommunication carriers and tenant from running
proprietary cabling throughout the airport for new and legacy tenants 
(2) Provides flexibility for new and legacy tenants as their technology requirements
change and business opportunities expand within the airport

(3) Provides the Port the ability to move new and legacy tenants into new and legacy
lease space quickly, improving customer service and maximizing revenue 
(4) Infrastructure is Port managed which allows us to quickly provision requests 
(5) Ability of quick technology activation from one lease to another lease space as tenants
move to any different leased spaces 
(6) Provides flexibility for new and legacy tenants to order telecommunication carrier
circuits as their data requirements change 
(7) Prepares for the future opportunity of multiple telephone/internet service providers
anticipated as part of the future "Meet Me Room" project which will allow for
expanded tenant communication choices and services. 
Cons: 
(1) Requires a larger capital investment up front, versus spreading the capital out over
several years. 
This is the recommended alternative.
