About Graves Construction Co INC
From gravesconst.com
Four Graves brothers, Fred, Bill, Lou and Amiel founded Graves Construction in 1920. The Company, originally a partnership, was known as Graves Brothers Construction. The early deaths of two of the brothers left Bill and Lou to continue operations in Iowa, South Dakota and Minnesota. In 1942 Bill and his son Kenneth took company equipment and personnel to Alaska for major structure work on the Alcan Highway.

Flatbed driver who delivered 50’ steel beams here! Overnight parked in their yard, friendly employees who unloaded me! They started at 6am and wasted no time getting the job done! Nice job guys! Appreciate it!
