mechanical upgrades are designed, pre work items are designated, Historical
Preservation Issues are resolved, product selections are made and the homeowner
design package is completed. |
| Assessment
Team |
A
team of technicians, engineers and architects who will document floor plans,
review the electrical and mechanical equipment, examine the structure, make
treatment recommendations and discuss treatments and products with the homeowner. |
| Assessment
Visit |
Visit
of the residence by the Assessment Team when existing conditions are documented,
homeowner is made aware of pre-work items and chooses products, styles and
colors. |
| Avigation
Easement |
Legal
Document that provides a perpetual right of way to aircraft to fly over
a residence in return for the sound insulation program improvements, that
is permanently attached to the property deed. |
| Certificate
of Occupancy |
A
Document containing a certified statement that a residence is habitable
and meets all local and municipal codes. |
| Code
of Conduct |
A
system of rules that dictate the way a Contractor is to act or behave while
construction is under way at a residence. |
| Condensation |
The
result of high humidity (moisture in the air) that produces a "fog"
when it hits a colder surface, such as a glass window. |
| Construction
Phase |
A
period of time from the selection of a Contractor to perform the work at
a residence and the final acceptance of the work. |
| Construction
Schedule |
A
timetable of specific events that occur during the construction phase with
specified time frames. |
| Contractor
Pre-Walk |
Visit
to a residence by the Contractor and the Construction Manager within 48
hours prior to the start of construction. |
| Day/Night
Noise Level |
(DNL)The
noise exposure at the Airport, is presented in terms of the average annual
Day-Night Sound Level (DNL) for existing conditions. The DNL measure is
the annual average of the total noise energy that occurs at a location.
DNL is used in the Part 150 Studies and in documents prepared it demonstrates
compliance with the National Environmental Policy Act (NEPA). Noise levels
were computed using the Integrated Noise Model (INM).
The INM was developed under the auspices of the FAA for use in Part 150
studies. The distribution of the noise pattern on each map calculated by
the INM is a function of the number of aircraft operations during the period
evaluated, the types of aircraft flown, the time of day when they are flown
the way they are flown, how frequently each runway is used for landing and
takeoff, and the routes of flight used to an from the runways.
All noise impacts associated with existing and future noise scenarios were
automatically calculated by combination of the contour set with the Geographic
Information System base map. |
| Decibel |
(dBA)
The unit of measurement of the intensity of sound. A higher decibel level
is louder. For every 10 decibels the noise level is doubled. If the noise
level is decreased by 10 decibels, it will only be half as loud. |
| Design
Phase |
Period
of time from the placement of a residence in a group to the designation
of a contractor to perform the work at the residence. |
| Eligibility |
Qualification
of a property for participation in the Residential Sound Insulation Program
by being located in a designated treatment area as defined by the Department
of Port Control. |
| FAA |
Federal
Aviation Administration |
| Final
Acceptance |
The
act of the Construction Manger inspecting and certifying that all work at
a residence has been completed in accordance with the Contract. |
| Final
Inspection |
A
visit by the Contractor and the Construction Manager at a residence for
the purpose of inspecting the work that has been performed to ensure that
the work has been performed satisfactorily to designate a date of final
acceptance of the work. |
| Final
Measurements |
The
Contractor and a representative will visit each residence to take final
measurements for materials that will be used during construction |
| Frequency |
("hertz",
cycles per sound) Measures the rate of vibration of sound. High frequencies
have a high pitch, like a whistle, while low frequency sounds are more like
the rumble of a truck or airplane. |
| Habitable |
Livable
area that is occupied year round and meets all code and building construction
requirements with respect to mechanical and electrical systems, foundation,
wall, ceiling and roof materials and structure. |
| Ldn |
Day-Night
Average Sound Level. |
| Noise
Abatement |
Procedure
for the operation of an aircraft at an airport which minimizes the impact
of noise on the environs of the airport. |
| Noise
Reduction |
(NR)
The difference, in decibels, of the average sound levels between two areas.
It is also a measure of the noise relief provided by construction such as
walls and windows. |
| Noise
Study |
Investigation
of existing noise conditions, flight patterns and land use surrounding an
airport. |
| One
Year Warranty Period |
The
one year period following final acceptance of all work performed at a residence
during which the Contractor must warrant his work to the homeowner. |
| Operation |
An
aircraft arrival at or departure from an airport. |
| Pilot
Program |
A
test phase consisting of a cross section of homes in a new area utilizing
standard noise abatement techniques and procedures along with rigorous acoustical
testing. This provides an opportunity to test the techniques and products
being used to determine if changes will be necessary to deliver the best
sound insulation product available. |
| Pre-work
Items |
Special
conditions involving building codes, structural conditions or existing building
conditions that will affect proper installation of sound insulation improvements.
The property owner is responsible for addressing the designated pre-work
items prior to the start of construction. |
| Punch
List |
A
list of unsatisfactory or incomplete work items that are identified by the
Construction Manager during an inspection of the work. The contractor must
complete all punch list work items satisfactorily before the home will receive
final acceptance. |
| SHPO |

Historical Preservation Office |
| Sound
Insulation |
Refers
to acoustical treatments that reduce noise (in this case aircraft noise)
inside the home. |
| Substantial
Completion |
The
point in construction when the work is almost finished and the contractor
is no longer in the home on a daily basis. After substantial completion
the final inspection will be performed and a Punch List prepared. The contractor
will then return to complete the punch list items. |
