All construction equipment est of shall be adequately muffled and maintained to minimize project noise. The installation of noise barriers is the r. minimum technique to suppress noise, especially when shoring and performing other specific localized area tasks. 11.2 Noise Suppression Plan All activity that generates noise in excess of 80 decibels (65 decibels during the summer season) requires a noise suppression plan and is restricted to operating between the hours of 9am and 5pm Monday through Friday. Koru will install noise reduction panels to the perimeter site fence (Behrens and Associates STC-25 Acoustical Blankets or approved alternate) and utilize portable sound blocking panels (Echo Barrier, acoustic noise barrier, or similar) to further mitigate sound as needed at specific localized areas, e.g.: surrounding compressors, mixers, shoring drill. The noise reduction panels will remain on the perimeter site fence from project initiation through the completion of foundation. Throughout the course of the project, the portable sound blocking panels will be placed in the following locations: See Appendix C - Noise Suppression Plan. • Shoring — in front of/ above the drilling rig, alongside the auger at its point of entry into the earth, and along ide the drilling rig. • Mixer—on all sides other than one slot for access to and from the mixer. The opening will be oriented towards the center of the site. • Concrete Saws and Coring —on all sides during cutting/coring. • Compressors—on all sides when outside of the structure. • Table Saws/ Cutting Areas—on all sides when outside the structure other than one slot for access to and from the cutting area. The opening will be oriented towards the center of the site. 11.3 Continued Noise Monitoring In addition to the standard practices agreed to within the signed Noise Suppression Plan, the table below from the City of Aspen's complete packet has been included for quick contractor/subcontractor reference in Appendix C— Noise Suppression Plan. 11.4 Requirements for Activities Exceeding 80 Decibels Activities exceeding 80 Decibels will be scheduled, communicated to neighbors, executed and minimized according to City requirements. Large scale works such as excavation will utilize a temporary noise barrier (Behrens and Associates STC-25 Acoustical Blankets with integral panels or approved alternate) located at the perimeter of the site. Smaller, more localized activities producing excessive noise such as compressors, and mixers,will utilize portable sound blocking panels (Echo Barrier, acoustic noise barrier, or similar). These barriers will be placed to protect the neighboring properties. The barriers will be built and maintained per the City of Aspen's guidelines 11.5 Specific Restrictions Related to Manufacturing on Site Activities exceeding 80 Decibels will be scheduled, communicated to neighbors, executed and reduced according to City requirements. 417 Ltd RECEIVED 417 Main St.,Suite Y �l Carbondale,CO 81623 Construction Management Plan Page 1 8 Phone 970.963 0577 1 130 Black Birch Drive 04/20/2018 ASPEN BUILDING DEPARTMENT Appendix A - Required Project Sign Dimensions— 36"W X 24"H koru Growth .

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.
