DATE:    November 7, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Ralph Graves, Senior Director, Capital Development 
Jeffrey Brown, Director Aviation Facilities and Capital Programs 
SUBJECT:  Capital Development Department (CDD), and Central Procurement Office (CPO)
Major Works Department move to the SeaTac Office Center (CIP #C800982) 
Total Authorization Request:         $9,057,000 
Estimated Project Cost:             $2,145,000 
Estimated Lease Cost:              $6,829,000 
Estimated Expense Cost:              $83,000 

ACTION REQUESTED 
Request Commission authorization for the Executive Director to (1) execute a lease amendment
for office space for the Capital Development Department (CDD) and Central Procurement Office
(CPO) Major Works Department to move into the SeaTac Office Center (STOC) for $6,829,000
and (2) execute contracts to purchase office furniture, and design and install communications
infrastructure to support business needs for $2,228,000. 
EXECUTIVE SUMMARY 
This project will lease additional office space in the STOC where the International Arrivals
Facility (IAF) project team currently holds a lease. This additional office space is needed to
accommodate growth in both the Aviation Division and CDD because there is no additional
capacity in the Airport Office Building (AOB) to accommodate anticipated staff growth over the
next five years.
Beyond the need to accommodate growth, the additional leased space allows CDD and related
departments to reorganize staff areas by project team versus traditional departmental lines.
This reorganization of staff will facilitate greater efficiency in project delivery and
communication for the capital program that continues to expand at Sea-Tac. The action
requested includes costs for communications design and construction, office furniture, and
relocation of staff to support business needs.

Meeting Date: November 14, 2017 
Staff is working on the development of a long-term plan to accommodate the increased staff
growth for Aviation and CDD. A follow-on study is budgeted in 2018, and is anticipated to be
completed in Q4 of 2018. This follow-on study will develop the Aviation Division and CDD's
longer term staff growth forecast, which will help determine the long-term sizing of a future
facility. The study will also include a sighting study, as well as determine if a purchase, new
development, or continued lease of office space is the best approach going forward. 
JUSTIFICATION 
The AOB is at capacity with the existing furniture and footprint and cannot accommodate
projected staffing growth. Projected building occupancy growth for employees and consultants
is estimated at an average of 30 people per year over the next five years, but does not yet fully
factor in projects anticipated to be part of the Sustainability Airport Master Plan (SAMP).
Beginning in January 2018, there will be new employees who will not have an available desk or
office. Temporary and shared spaces will need to be set up to accommodate the growth until a
proposed solution can be implemented later in the year. 
In early 2017 an office space study was conducted for the Aviation Division to determine how
to accommodate 5-year projected staffing growth in the AOB. Based on the study, and per the
direction of Aviation and CDD leadership, we determined the best option to meet the needs of
the projected growth was to move a large group of people out of the building and into an
expanded leased space in STOC. 
Moving CDD and CPO would provide the opportunity to co-locate project teams. Project teams
will occupy space in STOC as well as the off-site offices currently being used by these work
groups including the West Side Office, Water Tower Office, and Logistics Office. Grouping
project teams allows them to work more collaboratively and efficiently.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Densify AOB to accommodate growth 
Cost Implications: $12,021,000 
Pros: 
(1)   All current departments within the AOB stay in the AOB 
(2)   Provides room for 2-3 years of growth 
Cons: 
(1)   Each floor would need to be vacated for 1-2 months during construction 
(2)   Facilities & Infrastructure Library is eliminated and the contents are redistributed into
open areas and consolidated 
(3)   New cubicle and conference room furniture will be required 
(4)   All costs would occur in one year 
(5)   Based on information received from the Aviation staffing study conducted subsequent
to the AOB office space study, this option is not viable to accommodate 5-year
growth. 
This is not the recommended alternative.

Meeting Date: November 14, 2017 
Alternative 2  Purchase an existing building to accommodate growth 
Cost Implications: Unknown 
Pros: 
(1)   Could potentially offer greater long-term value and flexibility to the Port's capital
investment 
(2)   Could provide a longer term solution to office growth needs 
(3)   Would be a Port-owned asset 
Cons: 
(1)   Timing associated with acquisition of building could not meet the immediate need 
(2)   No location proximate to the Airport is currently available for sale 
(3)   Cost associated with a potential purchase is unknown

Alternative 3  Construct a new building to accommodate growth 
Cost Implications: Unknown 
Pros: 
(1)   Could potentially offer greater long-term value and flexibility the Port's capital
investment

(3)   Would be a Port owned asset 
Cons: 
(1)   Timing could not meet the immediate need 
(2)   Port owned real estate is limited and would require a siting study (currently included
in study budgeted in 2018) 
(3)   Minimum time frame to implement a construction solution would be five to six years 
This is not the recommended alternative. 
Alternative 4  Lease additional space in STOC to accommodate growth. Would require the
relocation of  Capital Development Departments  located at the AOB  and the Central
Procurement Office  Major Works Department located at the Logistics Office. 
Cost Implications: $2,228,000 Capital and Expense, $6,829,000 Lease 
Pros: 
(1) Provides the opportunity to collocate project teams at STOC, Water Tower, Westside
and Logistics office locations 
(2) CPO  Major Construction Department will be collocated with their major customer, 
CDD 
(3) Can be implemented in 2018 and should meet the anticipated five year need for space
in the AOB
