COMMISSION AGENDA – Action Item No. _10c__ Page 2 of 5
Meeting Date: December 15, 2020
Template revised June 27, 2019 (Diversity in Contracting).
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
