| 摘要： | As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE program, the South Carolina Department of Transportation (SCDOT) was awarded a $1 million grant to demonstrate the use of proven, innovative technologies for accelerated bridge replacement. This report documents the contracting methods and construction techniques used to replace four consecutive bridges over the Black River in Williamsburg County. This report includes construction details of A+B+C contract bidding with built-in no-excuse incentives and precast bridge beams made with self-consolidating concrete used to replace the existing bridges rapidly, safely, and with less negative impact on the traveling public than using conventional construction methods. Under conventional construction, the impact of this project on travelers was estimated at 28 months, but with the use of innovative contracting and construction methods, the impact was reduced to 14 months. This is a 50 percent reduction in the time required to complete the project. |
