LIRR'S West Side Yard
  ACS Underground Solutions had the task of working at the busiest train tracks in New York City during the relocation of the New York Jets New Stadium in 2004- 2005. The project was to clear over 200 test bores in and around the railroad tracks during the massive redevelopment of the site. ACS made sure that all electric, water, gas, sewer and communication utility lines stayed intact and running during this project. The most challenging task was working with DC Power from the tracks; the electrical power generated from the 3rd rail track made locating and marking out some utilities quite difficult. This by far was the most dangerous aspect of working at this site. Before work began at LIRR, ACS Underground Solutions technicians had to undergo 3rd rail safety training. They learned all the possible hazards of moving trains with high voltage tracks and all safety precautions were taken to reduce the risk of injury. Safety is one of our top priorities at ACS. We also take pride in completing all of our projects on schedule.


ACS Underground Solutions continued locating utilities at LIRR West Side Yard until the test bores needed clearing on the tracks. This task created some problems due to the 3rd rail and DC power supply. Our specialized technicians used GPR (ground penetrating radar) in some locations when they could. However, the railroad ties were blocking signals for the GPR is most areas. So ACS had to bring in specialized equipment to eliminate the interference from the DC and 3rd rail.


We chose to use a Vector Bar which eliminated all the interference that was causing the problems. The Vector Bar locates utilities at a very low frequency with high output from the transmitter. Test holes were excavated on site proving the accuracy of the ACS technicians utility markouts. This enabled LIRR West Side Yard to expose utilities, verify the mark outs and proceed with confidence on this site.


In 2008-2009 ACS Underground Solutions were contracted to the same site to clear an additional 55 test bores for a new developer. With our prior site knowledge and experience we successfully conquered this project with no mishaps or underground utility damage.
