For more than 35 years, the Federal Highway Administration (FHWA) has developed and maintained a document library in support of agency policy for the design and construction of structure foundations, earth retention, and other geotechnical features along highway alignments. An important goal with this effort is to provide sufficient information to allow an owner or transportation partner to assure reliability in a constructed feature and make a reasoned decision on acceptance and payment. The FHWA has funded an effort to develop a procedural methods framework for acceptance of structural foundations. The effort is intended to reduce tendencies for the misuse of construction control and acceptance tools, inequity in methods for different foundation types, and decision making based on incomplete information. This presentation will summarize this effort and demonstrate is applicability in practice.
