A $20 million "sequencing" facility for Ai-Genesee, a GM supplier, is going up in Flint, made possible by union labor and union pension dollars.

The 407,500 square-foot facility is being erected near West Maple and Linden roads. It is a project of Corvus International with partial financing by The Build Fund, a real estate fund that uses union pension dollars to build projects 100 percent union while providing competitive returns for investors.

The new building, expected to be complete later this year, will provide a facility for Ai-Genessee to assemble and sequence modules and components for the GMT Medium Duty Truck, which is assembled at the GM Flint Truck Assembly Plant.
