Abstract:

Despite possessing several advantages, drilled shafts are used infrequently ; in Iowa. The soil conditions in several regions of the state are ideal for ; using this foundation option. The reasons for the limited use of drilled ; shafts can be attributed to the following: ; • Lack of a formal process for selection of appropriate foundation types, ; especially in evaluating the advantages of drilled shafts over driven ; piles ; • Limited design guidelines and details for drilled shafts in the Iowa ; Bridge Design Manual ; • Absence of standard construction inspection checklists for drilled ; shafts ; Furthermore, the resistance factors for drilled shafts recommended in ; the American Association of State Highway and Transportation Officials ; (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design ; Specifications (2010) were determined based on a general national ; database that does not reflect local design and construction practices and ; the regional soil conditions.
