Update of RCB Culvert Standards to LRFD Specifications, TR-620

The Iowa Department of Transportation (Iowa DOT) desires to utilize consulting engineering services to bring the current reinforced concrete box (RCB) culvert standards into conformance with the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor (LRFD) Bridge Design Specifications, 2007 Edition (including 2008 and 2009 interims). This project is subdivided into five (5) parts as defined in Proposal to Update cast in place (CIP) Reinforced Concrete Box Culverts to LRFD by Mike Nop, Iowa DOT. The objectives of this research project are to update RCB culvert standards and designs for single, twin and triple barrel culverts of various sizes and various fill heights, flared wing headwall designs for each barrel configuration, and outlet flume designs for various barrel heights. Details for bell joints, flume basins, baffles, and culvert extensions will also be included with the RCB culvert standards. The Iowa DOT will obtain updated RCB culvert standards. The proposed software is a Windows application developed using Microsoft Visual Basic program language and tools. This approach will provide the end user with an application that can be readily installed and run on a common desktop computer or over a network, will not require additional software to run other than Microsoft Windows and will have a simple and intuitive user interface.
