Construction

7NT performs utility construction services for underground engineering and construction programs, including manhole repair, reconstruction, infiltration control, and lining systems.

7NT performs Utility Construction Services under a Master Service Agreement (MSA) for Citizens Energy Group, bringing manhole structures to specification.

The original 7NT service page referenced completed and contracted work orders covering approximately 450 manhole repairs and reconstructions, plus anticipated related work on the 34th and Voigt project and the Pleasant Run Consolidation Sewer Project.

7NT listed original public reference contacts for this service line as John Trypus and Tim Shutters with Citizens Energy Group.
