Dunbar and Sullivan Dredging Company records

 Collection
Identifier: GLMS-0003

Collection Organization

This collection contains files regarding construction projects at port facilities on the Great Lakes and along the Mississippi River undertaken by the Dunbar and Sullivan Dredging Co. of Cleveland, Ohio. Most of the construction estimate files are from projects completed before the merger of Dunbar and Sullivan with Merritt, Chapman and Scott by the latter company's predecessors, Whitney Bros. Co. and Merritt, Chapman and Whitney. Within the files are series on construction estimates, photographs, and correspondence. The files span the years 1891-1964. Of particular significance are the approximately 1,005 photographs of construction sites for docks, dams, and bulkheads. These items date from 1902-1982 and record the construction and maintenance of the technical support facilities for waterborne commerce in the United States for much of the twentieth century. Published materials have been separated for cataloging in the HCGL's library materials collection.
