consistent policy under which certain physical aspects of construction
management will be implemented on the Gorsuch Haus Project. The
approved Construction Management Plan will be kept onsite.
1.2 APPLICABILITY
This construction Management Plan shall govern the construction of Gorsuch
Haus.
1.3 DEFINITIONS AND TERMS
Construction Management Plan – A Construction Management Plan is a
combination of diagrams, documents, drawings, and specifications that
clearly define the steps that will be taken to demonstrate how the impacts to
the community will be minimized. How the impacts associated with any
construction project will be managed. Herein described as “Plan” throughout
the remainder of this policy.
Construction Mitigation Officer – An appointed employee of the City of Aspen
whose charge is to ensure that all aspects of a Construction Management
Plan are followed, and to further ensure that the impacts associated with
construction activities within the City of Aspen are effectively managed and
impacts associated with those projects are the least necessary to accomplish
the project.
Disturbance Area – A portion of land where topsoil or native soils have been
removed for purposes of construction (development).
Best Management Practices (BMP’s) – Schedules of activities, prohibitions of
practices, maintenance procedures, and other management practices to
prevent or reduce the pollution of waters of the state. BMP’s also include
treatment requirements, operating procedures, and practices to control site
runoff, spillage or leaks, waste disposal, or drainage from material storage.
Tree Dripline and Protection Zone - Use the longest branch of the tree as a
radius from the center of the tree and make a circle. The circle is then defined
as the dripline and thus is the tree protection zone.
Final Stabilization – Uniform vegetative cover has been established with a
density of at least 70 percent of pre-disturbed levels.

30 days prior to anticipated discharge.
9.0 FUGITIVE DUST CONTROL
9.1 FUGITIVE DUST CONTROL PLAN
RA Nelson will follow the dust control measures as outlined below. The scope of
work will meet the requirements set for in the State of Colorado Fugitive Dust Control
(APEN) permit as needed.
9.2 REQUIREMENTS
The following processes will be implemented to help minimize the impact of dust and
debris during the construction process:
A Filler Hydrant permit will be obtained from the City of Aspen Water Department
and water will be obtained from one of the approved filler hydrant locations as shown
in Appendix B & H of this document.
Trucks entering and exiting the site will be required to cover loads onsite to help
mitigate dust and debris migration
Vehicle speeds on site will be restricted to 10 MPH on construction access roads to
help minimize dust pollution.
Construction equipment and vehicles will be restricted to temporary access roads
and staging areas unless required to be off of these roads for construction related
activity.
Shuttling and Carpooling plans will be will be utilized to eliminate unnecessary travel
on temporary roads within the jobsite.
Access roads will include a gravel base to minimize dust from construction
equipment traffic on these roads. These roads will be maintained with watering truck
as required, to mitigate dust a result of these temp roads. See attached Site
Management Plan located in Appendix B.
Ground cover measures shall be installed in staging and entrances to prevent dust
and soil tracking. This will include temporary gravel material that will be removed at
the end of the construction phase as needed or when a temporary staging area is no
longer required.
Material stockpiles heights will be kept to a minimum practicable heights and
managable slopes.
Material stockpiles will use water misting/sprays as appropriate
Page 11 of 54
12 02.25.20 DRAFT PRINT
Stockpiling of materials will be located away from the project boundary when feasible
and downwind of sensitive areas to help minimize dust pollution.
A wheel washing station and/or anti-tracking material (Yellow Poly Pad or Gravel) will
be laid at the entrance/exit from the construction site as necessary.
The tracking pad will construction will be reviewed with the engineering department
for approval. Laborers and pressure washers will be utilized to clean truck and
equipment tires when leaving the site when needed..
A street sweeper will be utilized to keep the existing roads, up to and outside of the
construction fence, clean from construction debris, mud or other undesirable
materials, resulting from the project construction activities. Cleaning of existing roads
inside the site boundary will be carried out daily; however frequency will increase if
necessary. It is important to recognize that this needs to be monitored consistently
throughout the day, in light of site operations and weather conditions. All trucks will
exit through the provided wheel washing station and/or anti-tracking material
(gravel), which is located at the exit of the site. The street sweeping operation will
include all of the pavement areas as necessary.
10.0 EMISSIONS
10.1 GENERAL
All subcontractors will be required to verify that all vehicles meet the City of Aspen
Emissions requirements. Any vehicle that does not meet the requirements will be
asked to leave until verification that they have improved the vehicles emissions to
standards.
10.2 EMISSIONS FROM DIESEL POWERED ENGINES
RA Nelson will enforce that emissions from diesel engines operated within the City of
Aspen shall be of a shade or density no darker than 40% opacity, except for starting
motion no longer than 10 seconds or for stationary operation not exceeding 10
seconds.
11.0 NOISE SUPRESSION
11.1 GENERAL
Every reasonable effort will be made to minimize the noise impact of construction
activities. Noise limits for construction activities is 70 decibels during the summer on
season (6/1-Labor Day), 80 decibels all other times. All construction equipment shall
be adequately muffled and maintained to minimize project noise.
11.2 NOISE SUPPRESSION PLAN
See Appendix D for the Noise Suppression Plan. The plan includes information on
noise blocking methods, techniques, and common equipment and activities that
require noise suppression.
Page 12 of 54
13 02.25.20 DRAFT PRINT
11.3 REQUIREMENTS FOR ACTIVITIES EXCEEDING 80 DECIBELS
1. Any work producing noise levels over 70-80 decibels is not permitted to
commence until after 9:00 am and is not permitted on Saturdays. That includes but
not 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.
2. RA Nelson will 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. RA Nelson
will provide a phone number where the foreman can be reached prior to the start of
the job.
3. Equipment will be operated in accordance with manufacturer's specifications and
with all standard manufacturers’ mufflers and noise-reducing equipment in use and in
properly operating condition.
4. Notices will be posted to inform workers, including sub-contractors, about the
basic noise requirements, as well as specific noise restrictions, to the project.
5. Noise barriers will be installed around all equipment/activities specified in Table 1
of Appendix D. 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.
Additional equipment requiring Noise Suppression that will be used on site , to be
added to the City of Aspen Table 1, include a rock crusher and soil screener.
6. Portable loud equipment including generators, compressors, and cement mixers
will be moved to different sides of the property to reduce impacts on individual
neighbors.
7. The use of music radios on the site are not allowed.

12.1 CITY CONSTRUCTION MITIGATION OFFICER
The City Construction Mitigation Officer shall be assigned to the construction project.
The City Construction Mitigation Officer will complete random site visits to determine
if the project is following approved Plan and City requirements. The officer is not
intended to take the place of a City of Aspen building inspector.
12.2 CORRECTIVE ACTION
The City of Aspen will enforce construction mitigation corrections as follows:
Page 13 of 54
14 02.25.20 DRAFT PRINT
1. The first corrective action is a verbal warning and explanation of the violation with
a timeframe for completion.
2. The second corrective action is a written warning or correction notice with
timeframe for compliance.
3. Third and final notice is a “Stop Work Order” (red tag). If a stop work order is
issued, no more work can be completed until the violation is corrected.
Failure to correct violations and/or any threat to public safety could subject the
owner, contractor or both to a fine of $1000 a day as determined by the municipal
court.

City of Aspen
Construction Noise Suppression Plan
As the General Contractor for this construction project, I ___________________ hereby agree
to the following restrictions and will provide the necessary noise suppression (outlined below),
such that it will lesson the impact to the properties within 300 feet of the project located at
________________________________. 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.
_______________________________ _____________________________
Signature Print name
On-site Contact Phone # ___________________
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)
Hours of operation
All construction activity is limited to the following days and times:
Monday thru Friday Saturday Sunday
7:30 am to 5:30 pm 9:00 am to 5:00 pm No construction work is allowed
Constructions activities producing noise greater than 80 decibels are limited to the following
days and times:
Monday thru Friday
9:00 am to 5:00 pm
Work that is over 80 decibels which by law requires a noise suppression plan will not be allowed
for Saturday work that includes but not 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.
Construction activity is not allowed during all federal holidays.
Due to the congestion in Aspen when town is completely full, noise suppression plans will not
be approved for the following dates: Christmas Week (December 25 through Jan. 1), Food
and Wine Week in June (Friday thru Sunday), 4th of July day and/or weekend if it falls on
a Friday or Monday, and Labor Day weekend.
Revised 01/09/2013
Page 28 of 54
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.
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:
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.
Revised 01/09/2013
Page 31 of 54
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.
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.
