Vibrations

Purpose

The purpose of this subject is to analyze construction related vibration and noise (low frequency) sources prior to construction and address traffic related vibrations following construction, collectively, to prevent damage to nearby structures, nuisance to property owners and, in some cases, settlement in unstable soils.

When to use this subject

You will need to contact the Geology Unit if:

  • The Cultural Resources Unit performed a study that identified historic properties that a project could impact
  • Activities such as pavement breaking, pile driving, vibratory compaction, or other construction-related, vibration-causing activities are anticipated in close proximity to structures and unstable soil
    • Complaints are received from public due to traffic-related vibrations and low frequency noise

For specific process information, contact Jason Richter or Beth Lauzon. Alternatively, see the other guidance page.

How this subject fits into the overall project development process

Contact the Geology Unit during the design phase if:

  • The Cultural Resources Unit performed a study that identified historic properties that could be impacted by the project
  • Activities such as pavement breaking, pile driving, vibratory compaction, or other construction-related, vibration-causing activities are anticipated in close proximity to structures and unstable soil

During DESIGN, the Geology Unit will perform predictive analyses within project schedules to assess the potential for proposed construction activities to create problematic vibrations and low frequency noise. Analyses will inform project managers to consider, for example, alternative construction methods or contracting with a consultant to develop a vibration monitoring and control plan. The Geology Unit can also assist by reviewing vibration related specifications/special provisions, scopes of work for vibration consultants, and data, analyses and recommendations generated by a consultant prior to and during construction.

Contact the Geology Unit after the construction phase if there are complaints from the public due to traffic-related vibrations and low-frequency noise.

After construction, the Geology Unit can assess traffic-related vibration sources (typically, pavement-related), perform vibration and noise (L-weighted) monitoring, communicate with property owners and propose solutions to vibration and noise causing problems (if deemed as such).
