The H-JAIA Noise Insulation Program (NIP) – an Overview
The City of Atlanta/Department of Aviation, owners
and operators of Hartsfield-Jackson Atlanta International Airport is undertaking
a new Noise Insulation Program (NIP). The NIP is a voluntary program approved by
the Federal Aviation Administration (FAA) to make noise-sensitive properties located
in close proximity to airport boundaries compatible with aircraft noise. By providing
an array of extensive acoustical treatments to an eligible property, interior noise
levels can be greatly reduced, improving the quality of life for all occupants.
The NIP will provide these treatments at no cost to the property owner.
What Properties Are Eligible to Participate in the NIP?
To be potentially eligible, properties must meet two criteria: (1) they must be
located within the currently FAA-approved noise contours; and (2) they have not
been treated in a previous NIP. The currently approved contours are those contained
in the 2007 Noise Exposure Map (NEM). This
NEM was developed using the most recent operations data to include aircraft flight
paths, aircraft types, number of aircraft operations, times of operations, and runway
assignments. Properties contained within the NEM boundaries are located within the
cities of Atlanta, College Park, East Point, Forest Park, Hapeville, and Fulton
and Clayton counties, and they encompass a wide variety of property types including
single family, multi-family, schools, daycare, community centers, healthcare/retirement,
churches, and fire stations.
What Are the NIP Noise Reduction Goals?
Noise enters a building by the infiltration of air through doors, windows, roof
penetrations, and any opening connecting the interior living space of a building
with the exterior. The goal of the NIP is to reduce the infiltration of the exterior
noise into the interior living space by a minimum of five decibels.
What Types of Modifications Are Typically Provided to Eligible NIP Properties?
Given differences in property types, architectural design elements, and pre-existing
conditions, the NIP modifications will be property-specific. Modifications may include
some of the following treatments:
Prime entry door replacements
Sliding glass door replacements
Roof vent baffling
Addition of cellulose insulation
Addition of exhaust ventilation fans
Air conditioning modifications
Gas appliance venting modifications
Asbestos & lead paint abatement
How Will the NIP Be Implemented?
The Department of Aviation(Department), with assistance from it's consultant THC, Inc., will implement the NIP. The NIP will follow
THC's proven "Bid Cycle" methodology. A NIP Bid Cycle will contain all implementation
activities required to acoustically treat eligible properties to include property
owner orientation, property inspection survey, design survey, design development,
bid process, product procurement, and construction. A Bid Cycle will contain individual
Bid Packages, each containing designs and specifications for pre-assigned eligible
Once program startup is completed, the Department will implement a Bid Cycle to assure
that all processes provide maximum quality assurance. Upon completion, a new Bid
Cycle will begin every four to six months. This Bid Cycle methodology will provide
an efficient program implementation process where work is performed with maximum
attention from the Department and THC. In addition, this Bid Cycle methodology will provide
a NIP implementation pace that essentially eliminates work stoppage and maximizes
both administration and construction cost efficiency.
How Will the NIP Be Administered?
The NIP will be implemented as a traditional "Design-Bid-Build" project, where the
Department and THC, Inc. will be responsible for overall program management and design
and the Department will be responsible for the bid and construction processes. Local subcontractors
will contract with the Department's established Managing General Contractors to perform
the construction services.
