Paul Carpenter Associates, Inc. (PCA) was honored with the task of implementing a state-of-the-art remote monitoring system specifically for the World Trade Center (WTC) Redevelopment project. The monitoring program included four noise and five vibration monitoring terminals installed strategically within and along the perimeter of the WTC site that tracked compliance to Environmental Performance Commitments (EPCs).
PCA programmed the real-time noise and vibration monitoring equipment to transmit data continuously to an off-site server via wireless telecommunications technology. PCA delivered a customized user-friendly Compliance Website and provided training for Port Authority of New York & New Jersey (PANYNJ) inspectors. The website displayed current as well as historical data within graphs and tables, allowing users to quickly identify real-time noise and vibration compliance.
For additional support of the web interface, PCA also provided PANYNJ with instantaneous email alerts that warned of any vibration exceedance or equipment malfunction. Daily reports via email were also submitted by the system to authorized users. The noise monitoring terminals were programmed to record audio files once noise levels reached a specific trigger level and were automatically uploaded to the website. These audio files could then be played back by users directly from the website or downloaded for further review.
The system also provided a post-processing tool to allow PCA to filter monitored data against local meteorological data. Filtered noise and vibration data compiled during each month were generated by the system in an on-demand report submitted to the client. Noise and vibration monitoring terminals were routinely field-inspected by PCA staff and removed/reinstalled annually for accredited laboratory calibration. PCA also provided review and comments related to WTC-affiliated Noise Control and Mitigation Plans for various adjacent projects, such as the WTC Path Hall and Kowsky Plaza Water Pump House.
