Investigation Of Northeast Extreme Tee (Next) D Beam Bridges As An Alternative To Precast Hollow Core Bridges: An Exploration Of Appropriate Slab Design Forces, Daniel Deery
All Theses
Adjacent precast, prestressed concrete beam bridges have become a popular solution throughout the country because deck forming can be eliminated and construction is rapid. In South Carolina, adjacent beam bridges primarily consist of flat slab or hollow core sections, and they are currently only used on secondary, low-volume, short-span bridges. Durability and load sharing issues stemming from cracking, however, have caused concern with the longevity of these bridge types. Thus, the South Carolina Department of Transportation (SCDOT) has sought an alternative to the flat slab for short span bridges that can be used on high volume roads without an overlay. …

Evaluation Of Utility Relocation Costs And Best Management Practices, Michael Reinke
All Theses
In recent years, the SCDOT has experienced a significant variation in estimated costs for the relocation of utilities on many projects. This has led to cost overruns and caused concerns for the district engineers responsible for the projects. Through meetings with SCDOT personnel and utility company representatives it was determined that a standardized cost estimate form combined with improved change order management and cost management strategies was needed. Recently submitted estimates were analyzed and rated by a panel on multiple criteria to generate a list of 'poor', 'good', and 'excellent' estimates. The 'excellent' estimates provided insight into the development of …
