Groundbreaking will occur in late 2019 with completion expected in 2022. Subsequent phases of development may include the expansion of both structures and the construction of a second manufacturing building. The project team includes architectural firms Graef and Eppstein Uhen Architects with Hunzinger Construction as general contractor.
