MRC Rail & Bridge Rehabilitation Phase IMRC I 01_Cr.jpg

MRC Rail & Bridge Rehabilitation Phase I

Civil Design Inc (CDI) was the designer and contract manager for the project.  The project was broken up into 4 separate phases.  Each phase was bid separately and with its own strategically stipulated completion date. The first phase, tie supply, had 3 separate contracts and 2 suppliers.  The second phase, rail and OTM (other track materials) supply, had 6 contracts with only 3 suppliers. The third phase, rail rehabilitation, consisted of the prime contractor responsible for the installation of all materials and reconstructing the track.  The fourth phase, material salvage, consisted of a single contract for which the contractor picked up all removed rail and OTM. In all, CDI prepared and managed a total of eleven contracts for four phases of work, reaching $30 million in construction over a period of two years.. 

The volume of materials required to complete the project is unlike quantities experienced on any other railroad project completed within the State of South Dakota.  17,860 tons of steel were delivered in the form of rail and OTM.  That is equivalent to almost 750 loaded semi-truck loads. Over 106,000 crossties were installed as part of the project.  The project also installed 63,980 tons of ballast and 17,860 tons of rail and OTM. Ten reconditioned switches were installed along the rail line for access to useable existing sidings and new industries. 

The reconstruction of the MRC introduced several challenging issues.  The first challenge was that the original condition of the line was a sod railroad.  Typically sod railroads are not rehabilitated because they are typically not used for substantial rail traffic. There was no design information or previously constructed projects that were similar to this project. Very few contractors were willing to get involved in such a large project with unfamiliar conditions.  

Since the project was partially funded by a U.S. Department of Transportation TIGER II Grant (Transportation Investment Generating Economic Recovery), many additional stipulations were required such as only American made materials could be used. This condition required each length of rail, joint bar, bolt and tie plate to be inspected upon arrival to the site. That required each of the over 18,000 lengths of rail to be visually inspected prior to installation. 

The project was completed on November 26, 2012 and the rail line returned to the State of South Dakota and Dakota Southern Railway Company for operation.
