11.1 GENERAL
The noise limit for construction is 80 decibels measured at the property line of
the construction site. All construction equipment will be adequately muffled and
maintained to minimize project noise. The installation of noise barriers is the
minimum technique to suppress noise, especially when jack hammering of
concrete occurs.
11.2 NOISE SUPPRESSION PLAN
All activity that generates noise in excess of 80 decibels at the property line
would require a plan and would be restricted to operating hours identified
below.
11.3 REQUIREMENTS FOR ACTIVITIES EXCEEDING 80 DECIBELS
Any work producing noise levels over 80 decibels is not permitted to commence
until after 9:00 am and is not permitted on Saturdays. That includes but not
8
limited to the use of compressors, generators, jackhammers, power equipment,
nail guns, drilling machinery, earth moving equipment and similar loud
construction activities. This does not restrict quiet work inside and outside that
does not require a power source, including a battery, on Saturday.
Notify neighbors within two hundred fifty (300) feet of the project informing
them of the kinds of equipment, expected noise levels and durations of loud
work. Including the variation of noise levels during a typical construction days
may be helpful. Such notification must be in writing and be done seven (7) days
prior to the starting time of the project. Communication with neighbors can
prevent complaints from arising, and resolve concerns before there is a problem.
Provide a phone number where the foreman can be reached prior to the start of
the job.
Operate equipment in accordance with manufacturer's specifications and with
all standard manufacturers’ mufflers and noise‐reducing equipment in use and in
properly operating condition.
Post notices to inform workers, including sub‐contractors, about the basic noise
requirements, as well as specific noise restrictions, to the project.
The use of radios on the site before 8:00 am is not allowed.

City of Aspen Construction Noise Suppression Plan
As the General Contractor for this construction project, I Barrett Cyr, hereby agree to the
following restrictions and will provide the necessary noise suppression (outlined below), such
that it will lessen the impact to the properties within 300 feet of the project located at 535 E
Hyman Avenue, Aspen CO 81611. I understand that if any construction activities exceed 80
decibels and are not covered by this document I will contact the City of Aspen Environmental
Health Department to design a specific noise suppression plan for those activities.

Many activities on construction sites are noisy. Although some noise may be unavoidable, it can
often be controlled using improved work practices. Builders should make all reasonable efforts
to minimize noise. Noise Suppression plans are required for all construction projects where
activities will generate noise that exceeds 80 decibels. Section 18.04.050(A)(2)(d)
Specific noise suppression requirements for all activities exceeding 80
decibels at a construction site include:
1. Notify neighbors within two hundred fifty (300) feet of the project informing them of
the kinds of equipment, expected noise levels and durations of loud work. Including the
variation of noise levels during a typical construction days may be helpful. Such
notification must be in writing and be done seven (7) days prior to the starting time of
the project. Communication with neighbors can prevent complaints from arising, and
resolve concerns before there is a problem. Provide a phone number where the
foreman can be reached prior to the start of the job.
2. Operate equipment in accordance with manufacturer's specifications and with all
standard manufacturers’ mufflers and noise‐reducing equipment in use and in properly
operating condition.
3. Post notices to inform workers, including sub‐contractors, about the basic noise
requirements, as well as specific noise restrictions, to the project.
10
4. Install noise barriers around all equipment/activities specified in
Table 1: TYPICAL CONSTRUCTION EQUIPMENT REQUIRING NOISE SUPPRESSION. Noise
barriers not only significantly reduce construction noise, but they also provide an extra
benefit of “hiding” the noise producing sources, thus increasing a neighbor’s tolerance.
(See also the attached list of noise blocking methods for details on approved noise
barriers.)
5. Move portable loud equipment including generators, compressors, and cement mixers
to different sides of the property to reduce impacts on individual neighbors.
What can you do about construction noise?
The use of radios on the site before 8:00 am are not allowed: remind laborers and sub‐
contractors.
Noise suppression plans will not allow noisy machines such as brick cutters or
jackhammers to be operated before 9.00 am.
Noisy equipment such as cement mixers should be placed on the site to maximize the
distance from neighboring houses and/or rotate location so as to not impact just one
neighbor. Noise levels drop quickly with distance from the source.
All equipment should be properly maintained, with special attention to mufflers and
other noise control devices.
Between work periods, builders are required by city ordinance to shut down machines
such as backhoes, bobcats, loaders and generators.
When dropping materials from a height—for example, into or out of a truck, or when
loading or unloading scaffolding, noise suppression plans require a chute or side baffles.
All vehicular movements to and from the site must only be made during the scheduled
normal working hours. This includes off‐site noise that is associated with a specific
project such as staging of concrete trucks.

Noise Blocking Methods Contractors shall require all subcontractors and vendors to
use:
Quieter vs. Louder equipment
“Residential” grade combustion engine exhaust silencers
Electrical vs. pneumatic hand power tools: All pneumatic tools operated in the
City of Aspen must be fitted with an effective silencer on their air exhaust port.
Hydraulic vs. air powered rock drills
“Silenced” pile drivers vs. Diesel pile drivers
In general, noise reduction equipment and materials may include, but not be
limited to:
1. Shields, shrouds, or intake and exhaust mufflers.
2. Noise‐deadening material to line hoppers, conveyor transfer points,
storage bins, or chutes.
3. Noise barriers using materials consistent with the Temporary Noise
Barrier Materials Section.
4. Noise curtains
5. Plywood with concrete blankets at the height of the equipment and that
it surrounds the activity such that it directs noise up more than out from
the property.
6. Portable three sided enclosures made out of plywood to move with the
activity such as jack hammering.
7. Internal combustion engines are to be fitted with a suitable muffler in
good repair.
Specific Equipment:
12
Generators: The local power grid shall be used wherever feasible to limit
generator noise. No generators larger than 25 KVA shall be used and, where a
generator is necessary, it shall have maximum noise muffling capability.
Backup Alarms: All equipment with backup alarms operated by the Contractor,
vendors, suppliers, and subcontractors on the construction site shall be
equipped with either audible self‐adjusting ambient‐sensitive backup alarms or
manually‐ adjustable alarms. The ambient‐sensitive alarms shall automatically
adjust to a maximum of 5 dBA over the surrounding background noise levels. The
manually‐adjustable alarms shall be set at the lowest setting required to be
audible above the surrounding noise. Installation and use of the alarms shall be
consistent with the performance requirements of the current revisions of Society
of Automotive Engineering (SAE) J994, J1446, and OSHA regulations.
Compressors: The unit with the lowest noise rating which meets the
requirements of the job should be used where work is conducted in the City of
Aspen, installed with mufflers and/or enclosed in a noise barrier.
Jackhammer: All jackhammers and pavement breakers used on the construction site
shall have exhaust systems and mufflers that have been recommended by the
manufacturer as having the lowest associated noise and shall be enclosed with shields
or acoustical barrier enclosures.
Concrete crushers or pavement saws: Pre‐augur pile holes to reduce the duration of
impact or vibratory pile driving and tie to local power grid to
reduce the use of generators and shall be enclosed with shields or acoustical barrier
enclosures.
Pneumatic hand power tools: All pneumatic tools operated in the City of Aspen must be
fitted with an effective silencer on their air exhaust port.
Temporary Noise Barrier Materials:
Temporary barriers shall be constructed of 3/4‐inch Medium Density Overlay (MDO)
plywood sheeting, or other material of equivalent utility and appearance having a
surface weight of 2 pounds per square foot or greater. The temporary barriers shall be
lined on one side with glass fiber, mineral wool, or other similar noise curtain type
noise‐absorbing material at least 2‐inches. The materials used for temporary barriers
shall be sufficient to last through the duration of the construction project, and shall be
maintained in good repair. Prefabricated acoustic barriers are available from various
vendors. An equivalent barrier design can be submitted in lieu of the plywood barrier
described above.
13
Impact Equipment:
Impact noise is noise produced from impact or devices with discernible separation in
sound pressure maxima. Examples for impact equipment include, but are not limited to;
blasting, chisel drops, mounted impact hammers (hoe ram), and impact pile drivers.
Impact equipment is the loudest and most intrusive to the neighboring property. The
City of Aspen requires that this type activity have the strictest mitigation requirements
and requires a customized noise suppression plan specific to the site. General
contractors must contact the City of Aspen Environmental Health Department for an
application at 970‐920‐5039.
Noise Control
Replace worn, loose, or unbalanced machine parts that cause vibration.
Keep machine parts well lubricated to reduce friction.
Acoustical enclosures and barriers around generators
Sound absorbing material and vibration isolation systems on hand tools
Quiet work practices ‐ use rubber mallets to erect and dismantle formwork.
