D/2 supplied a volunteer crew cleaning stonework at the Quartermaster's office and Married Officer’s Quarters at historic Fort Wayne in Detroit, Michigan. The fort is situated on the Detroit River at a point where it is about a mile to the Canadian shore. The original 1848 limestone barracks still stands, as does the 1845 star fortification (renovated in 1863 with brick facing). Outside the original star fort are additional barracks, officers quarters, hospital, shops, recreation building, commissary, guard house, garage, and stables.
On Sunday, September 10, 2017 the National Trust HOPE project and the Historic Fort Wayne Coalition held a volunteer work day at historic Fort Wayne. Nearly 175 volunteers worked on the site in one day. The volunteers were divided into small work groups teamed with preservation trades professionals, many of them members of the Preservation Trades Network. Work consisted of rebuilding and carpentry repair, painting, window repair, repointing masonry, and masonry cleaning with D/2 Biological Solution.
