MTA & Heavy Infrastructure Monitoring

Our nations infrastructure is in a constant state of rehabilitation to keep up with current safety and expansion. The Big Apple Group's diverse team of Engineers and Technicians are well experienced in complicated heavy infrastructure advancement and have a phenomenal track record of assisting in the completion of difficult projects. Heavy infrastructure projects, such as roadway widening, utility upgrades, bridges, tunnels, and railway all require protection so that they are able to be completed safely and efficiently.

The Big Apple Group provides MTA, LIRR, SEPTA, NJ Transit, PATCO, MetroNorth, PANYNJ & Amtrak Railway and Tunnel Monitoring and Inspection Services. We develop specific Construction Monitoring Protocols to help avoid any adverse impacts on adjacent buildings and structures within the designated influence sone or construction boundaries caused by construction related ground-borne vibrations. Construction activities above the surface can affect underground structures and other transit systems. When a subway tunnel, bridge or railway is located within 75’ of the construction project’s influence zone, the following are required:

  • Pre-Construction Surveys
  • On-site Vibration Monitoring
  • Optical and Crack Monitoring

 

When monitoring New York City Transit Authority (NYCTA), NYDOT, NJDOT, PennDOT, DelDOT, SHPO, and countless other local angencie's structures, bridges, and tunnels; the requirements are different than other construction projects. Our Construction Monitoring Plans are customized to be project-specific to ensure a safe and efficient completion of your project.

Pre-Construction Surveys

The Big Apple Group delivers a combination of quick turnaround time and organized, detailed reporting that to ensure your project can start without delay due to lack of images or poorly documented pre-existing conditions. Our Track Certified inspectors work alongside Transportation Agency officials to ensure properly documented pre-existing conditions during surveys.

Vibration Monitoring

As mentioned previously, when monitoring transit-related structures, railways, bridges, and tunnels the requirements for monitoring vary from that of other projects in that remote monitoring is not permitted. All monitoring in these instances is conducted by our Track Certified Field Technicians. In addition, all of our technicians monitoring construction projects within the range of MTA, LIRR and Amtrak structures and transit systems are OSHA 10 Compliant.
