Accelerated Bridge Construction Utilizing Precast Pier Caps On State Highway 69 Over Turkey Creek, Huerfano County, CO

摘要

The purpose of this report is to document Accelerated Bridge Construction (ABC) techniques on IBRD (Innovative Bridge Research and Development) project 102470 for the construction of Bridge N-16-Q on State Highway 69 over Turkey Creek. The construction work was done on project FBR 069A-022, PC 15772, and was completed in July of 2011. During the course of the project, participants were able to: (1) develop a design methodology, (2) develop universal details, and (3) demonstrate how fast the bridge could be constructed using this technique. The project demonstrated faster pier erection by utilizing precast pier caps to eliminate concrete cure time from the critical path in the construction schedule.
