2004 Noise Study Construction Noise Control Options
1. Operational noise limits for construction equipment
2. Approved exhaust mufflers
3. Acoustic shields/shrouds on pavement breakers and jackhammers
4. Prohibiting construction from 8 PM to 7 AM if 5 dBA over background
5. Contractor to coordinate with facility users to reduce conflicts
6. Demolition near Stillwell Hall and Cavalry Stables to use quieter methods
7. Reduce the amount of pile driving
8. Use rubber-tired equipment rather than tracked vehicles
9. Storage and equipment located away from noise-sensitive sites
Additional Construction Noise Options
1. Construct a temporary noise barrier between the Crissy Field Centerand Doyle Drive
2. Conduct a building noise reduction analysis for the Center
CURRENT CONSTRUCTION NOISE CONTROL PLANFOR THE CRISSY FIELD CENTER
Temporarily relocate the activities of the Crissy Field Center to another location within the area until noisy construction activities within the areaare completed.
Benefits of the Crissy Field Center Relocation
1. Reduce potential for disruption of activities
2. Eliminate disruption from building insulation study
3. Eliminate the costs associated with a temporary barrier
4. Improve safety of Crissy Field Center users
CONCLUSIONS
• Construction noise control planning is an iterative process
• A general construction noise mitigation plan is a good starting point.
• Coordination and cooperation with interested parties aids in theidentification of concerns and leads to workable solutions.
• Keep the issues in perspective and keep the solutions simple!
