Needing to improve reliability and remain competitive, NYSEG turned to TRC to help guide the timely construction of this 5-mile long pipeline through upstate New York.

Project Location

Chemung County, NY

TRC was retained by New York State Electric and Gas (NYSEG) to provide Construction Oversight/Management services during the construction of this 5-mile long, 8” high-pressure natural gas line with the objective of improving reliability and keeping natural gas prices competitive. Two new meter and pressure regulating stations (M&R) were also constructed as part of the project. The pipeline route crossed an estimated 10 streams and 7 public roads. Horizontal Directional Drilling (480’) and open-cut methods were used to install the pipe.

TRC’s field staff, consisting of a Construction Manager and Field Office Manager/Inspector, reported directly to NYSEG’s Project Manager and assumed direct oversight responsibility for the contractor’s activities and all QC and craft inspection services. They also chaired weekly progress update meetings; ensured daily safety tailboards; collected and maintained all required field inspection reports and paperwork; monitored and managed the project schedule; and regularly discussed critical path activities with the contractor. When delays occurred, alternative means and methods were suggested to accelerate the schedule without incurring additional cost. To enhance communication, TRC developed a web-based collaboration site that provided access for TRC and NYSEG to store field documentation and related correspondence so that information could be retrieved and reviewed as it was needed.

To safeguard the environment, TRC field staff ensured full compliance with all Article VII ordering clauses, the project’s Stormwater Pollution Prevention Plan (SWPPP) and Water Quality Certificate, the US Army Nationwide Permit and all other associated regulatory documents. TRC additionally suggested that the Nitro Test method be used to test the transfer station piping rather than the Hydro (pressure water) Test, a decision which ultimately helped gain two (2) weeks in the project schedule for the client.
