In 1987, AASHTO-initiated research on the application of Load and Resistance Factor Design (LRFD) to bridge foundation design. The research was administered by the National Cooperative Highway Research Program (NCHRP) to develop NCHRP 24-4 and was summarized in report NCHRP 343, titled, “Manuals for the Design of Bridge Foundations.” Florida Department of Transportation (FDOT) first reviewed the research in 1992. However, the priority then was on converting the department’s practices to metric units. When the LRFD specifications were available in 1994, the FDOT looked at this issue more seriously. In early 1995, when FHWA’s LRFD training class was available via satellite broadcasting, FDOT had its engineers trained in some of those sessions. After the training, FDOT drafted an implementation plan in late 1995 and set up a timeline for the plan. The preliminary timeline was as follows: Oct 1995—Implementation Preparation; July 1997—Training; and July 1998—Implementation. This paper presents a brief case study of the FDOT implementation of LRFD specifications.
