Scope Of Work
Former MGP Site Remediation for major Michigan utility company:
Faced with a crumbling infrastructure and environmental concerns from a previous manufacturing gas plant (MGP) operation, a major Michigan utility company chose to remove and replace the existing storm sewers, water mains, asphalt and concrete pavements, site lighting and fencing. M.L. Chartier was selected as the contractor of choice for the project.
M.L. Chartier mobilized crews and equipment to the project in Flint, Michigan to perform the complete removal and replacement of existing parking lots, storm sewers, water main and site lighting. Major items of work performed by M.L. Chartier forces included dewatering, cleaning and removal of 2,500 lft of 24” steel gas lines, removal of 2,250 lft of 12”-18” storm sewer, removal of 16,500 syd of asphalt and concrete pavements, excavation, transportation and disposal of over 25,000 tons of MGP contaminated soils to a class II landfill, installation of 2,300 lft of 12”-18” storm sewer, installation of 1,485 lft of 4”-8” water main including hydrants and valves, and installation of 6,200 tons of aggregate base. Subcontracted work involving the installation of concrete pavements and curbs, electrical work for site lighting, asphalt pavement, fencing and gates and installation of pavement markings.
The project involved numerous challenges including maintaining pedestrian access to an existing customer service center and various below grade obstructions including concrete foundations and utilities. All groundwater encountered on the project had to be containerized on site and transported to a disposal facility due to MGP contamination concerns, this was accomplished by utilizing frac tanks and vacuum tankers that are owned and operated by M.L. Chartier. Crews worked 7 days a week and 24 hours a day on certain portions of the project to insure that customer access was maintained at all times with minimal disruption to the ’s daily operations. Through coordination with their subcontractors, M.L. Chartier the project without any injuries, below budget, in a timely manner, and to the ’s satisfaction.
