NiSource-Columbia Gas – Relief and Reconstruction after Gas Over Pressurization

Gilbane Reconstruction Services (GRS) assisted with the relief and reconstruction effort to over 9,000 residential and commercial customers that were currently without gas following an incident in early September 2018 of an over-pressurization of a gas-line.

The GRS team comprised of more than 350 individuals from around the country and managed the entire project from assessment to remediation through reconstruction. Overall there were 2,000+ people from a variety of companies that worked together to assist in the recovery efforts after this disaster.
