SUBJECT:  Rental Car Facility (RCF) Pavement Remediation (CIP #C800977) 
Amount of this request:              $ 6,845,000 
Total estimated project cost:          $ 8,303,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to advertise and execute a major
works construction contract for the Rental Car Facility  Pavement Remediation project at
Seattle-Tacoma International Airport. The amount being requested under this authorization is
$6,845,000 of a total estimated project cost of $8,303,000. 
EXECUTIVE SUMMARY 
Several RCF assets need renewal or replacement sooner than anticipated due to greater usage
and potential design errors and omissions or construction latent defects. The assets that will be
addressed include the floor expansion joints and topping slab, the helices, S. 160th St. driveway,
and the weatherproofing membranes in the car wash areas. Since the previous authorization 
for design, the scope of the project has increased to include the replacement of the existing
perimeter fence and resealing the employee and visitor parking. 
The RCF Lease Agreement between the Port and the Rental Car Operators ("Operators")
includes provisions for major maintenance improvements during the life of the facility.
According  to  the  Lease,  the  Port  is  responsible  for  completing  major  maintenance
improvements, which are to be funded from a major maintenance fund supported by Customer
Facility Charges (CFCs).  Major maintenance is generally classified as the full replacement of
certain assets, as defined in the Lease Agreement, or for repairs and replacements exceeding
$341,087.37, which is adjusted annually. CFCs are collected from rental car customers and the
funds are restricted for capital and operating costs that support the RCF and rental car
operations at the airport. This project is included in the 2019  2023 capital budget and plan of
finance. The current estimated project cost will result in budget savings of $2,184,000 from the
previously identified budget of $10,487,000.

COMMISSION AGENDA  Action Item No. ____                                Page 2 of 5 
Meeting Date: April 23, 2019 
The parallel effort that is looking into whether the need for remediation of any of the assets
being renewed could be attributed to design (Error and Omission) or construction (Latent
Defect) is still ongoing. Additional information on the progress of this effort is provided in the
"Additional Background" section of the memo. 
JUSTIFICATION 
The project scope includes several major maintenance improvements for the facility that the
Port has the responsibility to complete under the terms of the RCF Lease Agreement. The
Operators have requested that the Port complete these improvements as expeditiously as
possible since many are essential to their operations. Completing the perimeter fence in a
timely manner is also essential to ensure the safe and secure operations of the facility. This
project supports the Port's Century Agenda strategy of advancing this region as a leading
tourism destination and business gateway by meeting the region's air transportation needs at
Sea-Tac Airport for the next 25 years. 
DETAILS 
The project will be completed in two phases. Phase one consisted of the early replacement of
critical portions of the fifth floor topping slab in support the Operators' request for expeditious
action and was completed in October 2018 by Port Construction Services (PCS). Phase two
includes the remaining scope. 
The project scope has been modified during the design phase. The scope decreased with the
reduction in area for the replacement of the fifth floor topping slab since testing proved it was
not as damaged as originally thought. The scope  increased to include the replacement of
existing perimeter site fencing with a 10-foot no-climb fence to address site security concerns 
and resealing the fifth floor employee and visitor parking areas to address weather proofing
and safety concerns at these locations. 
Diversity in Contracting 
Project staff worked  with the Economic Development Division   Diversity in Contracting
Department and determined this contract will have an eight percent WMBE aspirational goal. 
Scope of Work 
The project will complete the major maintenance improvements described below. 
(1)   Replace and upgrade the fifth floor expansion joints in the bus operation area 
(2)   Replace and upgrade portions of the fifth floor topping slab in the bus operation area
due to excessive cracking and spalling 
(3)   Route and seal cracks in the deck and beams of both Helices 
(4)   Complete pavement rehabilitation on the existing S. 160th St. driveway 
(5)   Replace the weatherproofing membrane at carwash areas at the RCF located on the
second and fourth floors of the facility 
(6)   Replace existing perimeter fence with a 10-foot no-climb fence

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  No major maintenance improvements are completed for the RCF. 
Cost Implications: $0 
Pros: 
(1)   Capital investment not required. 
Cons: 
(1)   The Port does not meet its obligations under the terms of the RCF Lease Agreement. 
(2)   The facility could suffer further damage that could make portions of it unusable by the
Operators and significantly reduce its asset life.

This is not the recommended alternative. 
Alternative 2  This alternative includes the original project scope that was authorized by the
Commission. 
Cost Implications: $3,000,000 
Pros: 
(1)   The Port meets its obligations under the terms of the RCF Lease Agreement. 
(2)   The improvements are completed that maintain or prolong the asset life of the facility. 
Cons:

(2)   Significant impacts to facility operations during construction. 
(3)   A key security concern at the RCF would continue without being addressed. 
(4)   Does not reseal the employee and visitor parking areas to address weatherproofing
and safety concerns. 
This is not the recommended alternative.

Future Revenues and Expenses (Total cost of ownership) 
According to the terms of the RCF Lease Agreement the Operators are responsible for majority of
the on-going operating and maintenance costs of the facility. 
ADDITIONAL BACKGROUND 
Staff is separately investigating whether any of the deterioration of the assets being renewed is 
due to design (errors and omissions) or construction (latent defects) of the facility. To date
discoveries associated with this effort have led to: 1) the completion of the Bridge 2 structural
improvements through a three-party agreement with the Port, Contractor, and Designer of
Record, 2) reductions in scope of the fifth floor topping slab replacement, and 3) reduction of
number of carwash areas requiring replacement of the weather proofing membranes. These
findings reflect a savings of just over $1,000,000 to the project. 
Staff continues to work on determining the root cause of the severity of the helix cracking and
the waffle pattern radiating at the fourth floor carwash area. Both efforts are expected to be
completed by end of second quarter of  2019.   If the Port does ultimately receive
reimbursement by either the Designer of Record or Contractor, those funds will be used to
replenish the CFC Fund to the extent the costs reimbursed were paid for with funds from the
CFC Fund.
