Acoustical Design Criteria Development

Preliminary Acoustical Specifications for Design Development Stage

• Wall construction (STC)
• Door and window construction (STC)
• Ceiling/Floor Construction (STC)
• Mechanical systems sound attenuation package (NC)
• Method for treatment of penetrations (electrical outlets, ductwork, plumbing, etc.) (STC)
• Interior Acoustics treatment (RT60)

Preliminary Report and Review

1. Submit a report including the results of the acoustical analysis and the construction specifications for review by the architect.
   
   
2. Review meeting to present and discuss the results of the report, address questions, and consider design modifications.
   
   
3. Submit revised report incorporating any changes agreed to during the review meeting.

Late Stage Review and Construction Administration Oversight

1. Acoustical Systems, Inc. will provide technical review of design changes made after the completion of the Design Development Phase. The review will consider the effect proposed changes may have on the acoustical integrity of the construction.
   
   
2. Acoustical Systems, Inc. will provide periodic construction site inspections to review construction methods as they relate to the acoustical criteria of the project.

Post-Installation Acoustical Testing

1. Upon completion of construction, Acoustical Systems, Inc. will perform Sound Transmission Class (STC) testing, Noise Criteria (NC) testing, and Reverberation Time (rt60) testing of to document the acoustical environments of the new interior spaces and compare the results to the design criteria of the project.
   
   
2. Submit a final report of the final measured acoustical values and a comparison with the project design criteria to validate the acoustical performance of the facility.

Sound Level Tests

Project Management

• Coordination of all interior and exterior activities.
• Submit progress reports as requested.
• Oversee the project for the successful completion of the noise control compliance program.
• Review concept drawings with production and maintenance personnel.
• Prepare the necessary construction drawings for all acoustical fabrication.
• Review construction drawings with project manager to determine what, if any, production ramifications may result.
• Make any necessary modifications resulting from the production, maintenance, and project manager input.
• Determine, along with maintenance personnel, what materials and hardware will be fabricated in-house.
• Secure final written approval of the construction drawings from production personnel.
• Procure competitive bids on all materials that will be supplied by outside vendors and update ASI contract price if necessary.
• Along with the purchasing department, select the supplier and provide the necessary delivery information to maintenance for installation scheduling.
• Review approval drawings with the vendor prior to any fabrication.
• Assist vendor’s installation supervisor to insure a complete material installation.
• Qualify the noise reduction achieved after installation has been completed and present a final report to all parties.
