Limit state design (LSD), also known as load and resistance factor design (LRFD), refers to a design method used in structural engineering. A limit state is a condition of a structure beyond which it no longer fulfills the relevant design criteria.

Three in common usage are listed below: 1. Factor on load. The Geotechnical Design Manual focuses on geotechnical design, construction, The Geotechnical Design Manual focuses on geotechnical design, construction, and maintenance to ensure that the soil or rock beneath the ground surface can support the loads and conditions placed on it by transportation facilities.
Washington State State departments of transportation (DOTs) are at various stages of implementing the AASHTO. Load and Resistance Factor Design (LRFD) specifications (AASHTO LRFD, 2007) for the design of bridge foundations. Some DOTs still use the allowable stress design (ASD) method (AASHTO Standard Specifications, 2002) for the geotechnical Table 1043, Cut ERS Performance Limits at EE I Limit State. 1047 SCDOT Geotechnical Design Manual GEOTECHNICAL PERFORMANCE LIMITS August 2008 10iii GEOTECHNICAL DESIGN MANUAL Page 5 of 8 Embankment stability design should be consistent with stateofthepractice design guidelines, including but not limited to the referenced publications in Section 9.
