City of Sunny Isles Beach —Acoustical Engineering Services for the Town Center skate Park — Phase I Assessment 2. Field monitoring will be performed to establish background sound levels (Skate Park closed) and ambient readings during regular and peak Skate Park usage operational hours. Field monitoring will be conducted with a two (2) person team on Monday, Wednesday and Saturday (peak usage), Weather conditions and schedule demands may require an adjustment in the field monitoring days. 3. CadnaA Computer Modeling — Modeling of the ambient existing conditions for when the Skate Park is open and when the Skate Park is closed will be performed. Modeling and results for three different mitigation options (to be discussed and determined by our team) will be performed. Sound level contour exhibits will be generated for the three residential buildings' ambient conditions and the three mitigation options evaluated. A full enclosure (building) is not a mitigation option to be. evaluated by this study, 4. Draft and Final Report —A well documented report that will include: • Discussion of general sound levels and sound information including examples of typical sound levels associated with common sources or activities • Summary of the methodology, process and analysis used for the sound evaluation • Results of the field measurements and observations for ambient existing background sound levels and other sources of background noise observed in the vicinity of the Skate Park • Results of computer modeling (ambient and mitigated) with sound contours and associated sound level reduction at multiple receptor points within the three (3) residential buildings of the Salem House, 300 Winston Tower and 600 Winston Tower • A table providing a comparison of the mitigation options with sound reduction and construction material cost estimates • Basic drawings /engineering exhibits of the three (3) sound mitigation design options • Discussion of the benefits and drawbacks of the three (3) sound mitigation options • A recommended mitigation option and conclusion • Appendix with Photograph Log 5. Structural engineering review of the proposed mitigation options. 6. Construction Cost Estimating of the proposed mitigation options. 7. Presentation to the City Commission — PowerPoint presentation and three (3) exhibit boards with the proposed sound mitigation options. Participation by the three (3) key team members. Page 2
