Section 8: Noise/Sound Walls
TxDOT will
ensure compliance with commitments made for the project regarding noise abatement. If necessary, do the following as required in the contract:- Ensure the Contractor isaware of the commitments pertaining to noise abatement as proposed in the traffic noise analysis report and as implemented in the PS&E.
- Ensure the noise/sound walls required by commitments are installed to provide mitigation to adjacent impacted noise-sensitive receptors.
- Ensure that district environmental staff and ENV are notified and/or given an opportunity to review change orders that affect noise abatement included in the PS&E. ENV submits inventory information on constructed noise barriers to FHWA every three years and needs accurate information about changes.
If phasing or timing regarding noise/sound walls are not specified in the general notes or traffic control plan of the PS&E, contractors are encouraged to schedule and perform work related to noise/sound walls early during construction. This provides mitigation for noise impacts to communities adjacent to the project.
Upon completion of construction of one or more noise/sound walls, the Engineer will notify District Environmental Staff and provide information to complete ENV's "
". District Environmental Staff will then upload this information to ECOS under the "Perform Noise Mitigation", activity. Ensure all components of the spreadsheet are completed in accordance with the instructions in the spreadsheet template. Information about completed noise barriers are provided to FHWA every three years for the noise barrier inventory.
