THE 



RAPIDAN 

 DAM 



AS AN EXAMPLE OF 

 EFFICIENCY 





December 29, 1910 



March 2, 1910 



The above dam was built in 

 1910 on the Blue Earth River, 

 for the Consumers Power Co., 

 under H. M. Byllesby & Co., of 

 Chicago, engineers. Height, 60 

 feet above water line; length 

 over all, 450 feet. It contains 

 a three-unit power house and 

 carries a highway bridge across 

 the crest, replacing the iron 

 bridge seen in the first cut. 

 The contract was signed March 

 2, 1910. Work began March 

 15th, on which day the upper 

 photograph (although taken De- 

 cember 29th previous) repre- 

 sents the site. 



The lower view was taken December 29th, 1910, showing the work practically 

 completed. The total construction period from signing contract was therefore 302 

 days, or almost exactly ten months. Current was delivered to the consumers on 

 March 1st, 1911. 



This is not our record job, in point of time, but i ; nevertheless an excellent 

 example of rapid construction and efficient administration.
