2008 AML Emergency Projects Report
In the spring of 2008 the AML Division conducted an emergency project in the right-of-way of State Highway 36 near Wilton to fill an underground mine sinkhole. This project was completed at a cost of $2,016.
In May and June, the AML Division conducted an emergency project to drill and pressure grout underground mine voids east of Williston. A large void was detected between the driveway and concrete floor of a building that is used for a metal crafting and landscaping business. The driveway and locations around the building were drilled to locate additional voids and more than a 1,000 yards of grout were used to fill the voids. This project was completed at a cost of $109,185.50. Since this amount exceeded the total amount of the emergency project award, $100,000, some construction funds were used for this project.
The AML Division carried out another emergency project in early July of 2008 to fill an underground mine sinkhole that was immediately underneath and alongside the basement of a home north of Parshall. A grout mixture was used to gravity fill the sinkhole; however, the concrete floor in the home was damage while filling the sinkhole and repairs were made and a structural survey of the home was conducted to check for any other damages. The total cost of this project including the cost of grout, repairs and structural survey was $16,699.34. Since the emergency grant amount had been expended, construction funds were used to pay for this project.
