Situation:

This 345 kV substation yard expansion was part of the Greater Springfield Reliability Project, designed to improve transmission system reliability and ease transmission bottlenecks in the greater Springfield and north central Connecticut. To deliver this critical project, BOND was engaged to perform several key upgrades. The scope of work included: the removal of the existing foundation and the construction of new equipment foundations within the existing 115 kV substation yard, a new gas insulated transmission line concrete envelope structure and associated support foundations within the 345 kV yard expansion area, the construction of 150-new equipment / bus support foundations within the 345 kV yard expansion area along with associated ductbank and grounding, and the placement of yard stone surfacing.

Challenges:

  • Severe weather events including Superstorm Sandy and the Blizzard of 2013
  • Challenging terrain including ledge, tight sites and sensitive environmental areas
  • Located across many residential and neighborhood communities
  • Aggressive construction schedule

Solutions:

  • Constant coordination and site management with state and local officials
  • Strict communication protocols with area residents to keep them informed of construction activities
  • Tight scheduling and safety management protocols in conjunction with weather tracking reports

Results:

  • Met stringent federal and regional reliability standards
  • Completed on time and within budget
  • Improves the flow of power in and around the greater Springfield, north-central Connecticut area, while connecting customers to less expensive, more efficient generation
