Construction noise related to transportation projects is typically addressed in the project's noise analysis report and in the project environmental document. Most projects will not require modeling or any form of analysis associated with construction-related noise. In many cases, construction noise may be adequately addressed through a narrative discussion.
Some projects may require application of a simplified manual calculation technique. For projects that require compliance with local ordinances, more detailed analysis techniques may be called for. Use of the most sophisticated and complex modeling techniques are typically required for the most complex projects such as the Big Dig in Boston, MA, or the TREX in Denver, CO. Such projects may require in-depth analysis including modeling, operation scheduling, continuous noise monitoring, and enforcement.
Regardless of the type of project, it is important that any abatement techniques developed to address construction noise consider cost-effectiveness. Also essential is that construction noise criteria are attainable, easily understood, and well communicated to contractors and the public.
