Abstract:ODOT has used a commercial program, GRLWEAP, very successfully in the field over the last fifteen years to estimate the load bearing capacity of piles during driving and to finalize pile depth. Starting in 2007, states were required to use a new design method on structures called Load and Resistance Factor Design (LRFD). The LRFD design method required users to multiply the nominal load bearing capacity of piles estimated by the GRLWEAP program by a default resistance factor to conservatively account for unknowns. This default factor produced more conservative pile designs than those prior to LRFD. In essence, the new design code forced ODOT to build foundations beyond the high level of safety achieved with the previous design method resulting in more expensive bridge construction.
