EXECUTIVE SUMMARY 
As part of the Port's long-termcommitment to communities surrounding the airport, it is
necessary to offer sound insulation for up to 140 single-family homes, 903 apartment units within

individual construction contract procurements as designs are completed for each of these
programs.

Meeting Date: December 15, 2020 
On February 25, 2020, the Commission was briefed on the status of the Sound Insulation Program
(SIP) and instructed staff to complete these programs by the end of 2026. 
JUSTIFICATION 
Resolution No. 3683 was adopted by the Commission on October 22, 2013 and included all
recommendations from the Part 150 Study, including sound insulation for eligible structures
within the Noise Remedy Boundary. The goal of this program is to meet the requirements of
Resolution No. 3683 to conduct an ongoing SIP. In February of 2020, the Commission instructed 
the SIP to accelerate this work with the goal of completing work on these programs by the end
of 2026. 
Diversity in Contracting 
Since the SIP is anticipated to be up to 80% FAA grant funded, the Port's Diversity in Contracting
department will establish a Certified Disadvantaged Business Enterprise (DBE) requirement for
subconsultants on this procurement. DBE requirements will also be established for each of the
follow-on construction procurements. DBE program efforts will be administered in accordance
to United States Department of Transportation's small business program via 49 CFR Part 26. 
DETAILS 
The Port will provide funding and a limited number of FTEs to oversee the selected consulting
firm's activities, for the sound insulation of eligible properties, within the Noise Remedy
Boundary. These services will include assisting with SIP program management, property owner
outreach and prequalification, acoustic testing, project design, project management, and on-site
construction management. 
For a property to be eligible for participation in the SIP, it must be located within the FAA
approved Noise Remedy Boundary and must have been built prior to the establishment of local
jurisdictional building codes enacted to either meet, or exceed the FAA standards for noise
reduction. These dates include December 3, 1986, for the City of Des Moines and September 6,
1987, for all other areas of King County. 
In 2012, the FAA implemented an acoustic testing qualification requirement for all properties
participating in FAA-funded SIP based on pre- and post-construction noise audits. Each structure
must be tested pre-construction to ensure the interior noise level is 45 dB or greater with a
minimum reduction of 5 dB that can be achieved through sound insulation treatments. Some
structures  may not qualify  for participation in the SIP  because of the  acoustic testing
requirement. 
The primary goal of the SIP is to achieve the FAA standard 45 dB or less interior noise level. This
work includes installing new Sound Transmission Class (STC) rated windows, doors and storm
doors as well as providing supplemental exterior ventilation, upgraded smoke and fire detectors
and other items as required by code for each location. It is anticipated that up to approximately

Meeting Date: December 15, 2020 
80% of eligible costs will be funded by FAA Airport Improvement Program (AIP) grants assuming
the availability of grant funding is consistent with the Commission's February 2020 motion
concerning acceleration of the sound insulation program. 
The selected consulting firm will have experience in FAA sound insulation work with oversight
provided by the Port. This consulting firm will help determine whether a property within the
noise remedy boundary meets FAA eligibility and owner participation requirements. 
The pre-construction acoustic testing and design of potentially eligible properties will allow the
consulting firm to more fully define the scope of each project and develop detailed cost estimates
prior to Port staff seeking authorization for the procurement of construction contracts. 
There are 140 potentially eligible single-family homes within the Noise Remedy Boundary, 
however based on historical participation data, staff expects a maximum of 80 owners to enroll. 
Scope of Work 
The Port has overall responsibility for the SIP and is the sponsor of each program/project. The
selected consulting firm will regularly report to and communicate with various members of the
Port's SIP team and other program/project stakeholders, as required by the Port. 
The selected consulting firm will provide support during the following program/project phases,
to include: 
1.  Program Development and Planning 
2.  Program Participant Outreach and Pre-qualification including but not limited to acoustic 
testing for eligibility and obtaining required homeowner documents 
3.  Construction Project Design 
4.  Construction Contract Procurement 
5.  Pre-Construction 
6.  On-site Construction Management 
7.  Construction Project Closeout 
8.  Construction Project Warranty Phase and post-construction acoustic testing 

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Procure individual consultant support Service Contracts for the Single-Family,
Apartment and Places of Worship SIP. 
Cost Implications: $200,000 more than the preferred alternative during the life of the contracts. 
Pros: 
(1)   Provides flexibility if a consultant fails to perform well. 
(2)   Allows for the work to be distributed to multiple consulting firms.

Meeting Date: December 15, 2020 
Cons: 
(1)   Coordinating and administering three contracts will complicate program acceleration. 
(2)   Three contracts require more Port resources, time and money to administer and
manage. 
(3)   Three contracts do not encourage continuity and consistency between programs. 
(4)   Consultant staffing augmentation is more difficult with three contracts. 
(5)   There is less interest from the consulting community in smaller contracts. 
This is not the recommended alternative. 
Alternative 2  Procure two consultant support Service Contracts and divide them between the
Single-Family, Apartment and Places of Worship SIP. 
Cost Implications: $100,000 more than the preferred alternative over the life of the contracts. 
Pros: 
(1) Provides flexibility if a consultant fails to perform well. 
(2) Allows for the work to be distributed to two consulting firms. 
Cons: 
(1) Coordinating and administering two contracts will complicate program acceleration. 
(2) Two contracts require more time and money to administer and manage. 
(3) Procuring two contracts does not encourage continuity between programs. 
(4) Consultant staffing augmentation is more difficult with two contracts. 
(5) There is less interest from the consulting community in smaller contracts. 
This is not the recommended alternative. 
Alternative 3  Procure one larger consultant IDIQ contract for the Single-Family, Apartment and
Places of Worship SIP. 
Cost Implications: $40 million. 
Pros: 
(1)   Supports acceleration and continuity across all programs. 
(2)   Is less expensive and time consuming to procure. 
(3)   Is simpler for the Port to administer and manage. 
(4)   Allows more consultant resources to be committed to a larger contract. 
(5)   Enables consultant to react more efficiently to fluctuations in staffing needs. 
(6)   Is consistent with the best practices learned from recent peer reviews with other
airports/municipalities and is recommended by the Executive Review Panel. 
Cons: 
(1) Increases risk if there are difficulties with the consultant's performance. 
(2)   Work is not distributed to multiple firms. 
This is the recommended alternative.

FINANCIAL IMPLICATIONS 
There is no funding request as part of this authorization. Funding for the associated scopes of

service directives will be executed to authorize the consulting firm to perform any specific work
on the contract against the approved program/project or spending authorizations and within the
total contract amount.
