The birthplace of General Motors

The automotive giant salvages the place from which it sprang, 131 years ago.

November 27, 2017 |

When William Crapo “Billy” Durant and Josiah Dallas Dort leased a cotton mill in Flint, Mich., in 1886 for their new carriage-building business, no one could have predicted that, 22 years later, Durant would gain control of Buick Motor Company from its founder, David Dunbar Buick, and form General Motors Company. The old cotton mill, known as Durant-Dort Factory One, is regarded by historians as the place where GM was born.

Over the years, Factory One went through hard times. Four years ago, General Motors formed a collaboration with the Durant-Dort Office Carriage Company Foundation, the Genesee County Historical Society, and Kettering University to save this important piece of Flint and automotive history. GM bought the 30,184-sf building and brought in SmithGroupJJR and Brencal Contractors to turn the building into offices, an archival center, and event space.

By 2014, the National Historic Landmark had seen better days. The grade of the building had fallen 18 inches. Runoff submerged the first floor and eroded the brick masonry bearing walls, causing foundation settling. The project team replaced 17,000 damaged bricks with color-matched substitutes. Five thousand linear feet of mortar, representing 20% of the mortar on the building, was carefully blended to match the color of the existing mixture.

A new roof, new doors, and custom mahogany divided-pane windows were installed. The windows were painted green to match the historic Durant-Dort Carriage Company building across the street.

Portions of the second level dipped 9½ inches. These areas were leveled with a new raised subfloor in which power and data communications were installed. The renovation of the second story now provides a workspace, kitchenette, and meeting areas for GM employees. Factory One also provides space for community groups to rent for events.

The building houses a GM carriage-building and vehicle-manufacturing collection of more than 100,000 documents, some of which date to the late 19th century. To protect the archives from temperature variation and humidity, SmithGroupJJR designed a glass-encased, vapor-sealed room in the center of the building. A mechanical system maintains a temperature of 72° F (plus/minus two degrees) and a relative humidity of 50% (plus/minus 5%).
