Utility Construction Services

7NT is currently performing Utility Construction Services under a Master Service Agreement (MSA) for Citizens Energy Group.  This work involves bringing manhole structures to specifications.

In the last 6 months 7NT has completed 5 work orders under our MSA involving repair and reconstruction of approximately 150 manholes. 7NT is currently under contract for another 8 work orders involving repair and reconstruction of approximately 300 additional manholes.
