The FHWA has released for download a comprehensive update to the O'Neil and Reese manual "Drilled Shafts: Construction Procedures and Design Methods", lovingly referred to in the industry as the "Brown Book" or the "Drilled Shaft Bible". (FHWA-NHI). This manual is the reference text used for the National Highway. FHWA-NHI 7 - Drilling Fluids Drilled Shafts Manual May resulting seepage into the formation cause a positive effective stress against the walls of the borehole, which acts to hold the membrane in place. It is the combination of membrane formation and positive. the scope of this manual, and can be found in Federal Highway Administration Publication, FHWA/NHI The subsurface investigation plays a critical role when drilled shafts are contemplated for a bridge.

FHWA-NHI 1 - Overview Drilled Shafts Manual May Although there has been a significant evolution of the drilled shaft industry over the past 40 years to the type of construction and design which is prevalent today (), machine drilled shafts became more widespread during the ’s and became increasingly used during the building boom after World War II. Drilled Shafts in Shale. Publication. FHWA-NHI, “Drilled Shafts: Construction Procedures and LRFD Design Methods” (FHWA-DS) was published in and presented updated methods for determining the geotechnical axial capacity of drilled shafts in rock. These updates have since been incorporated. This manual is intended to provide a technical resource for engineers responsible for the selection and design of drilled shaft foundations for transportation structures. It is used as the reference manual for use with the three-day National Highway Institute (NHI) training course No. on the subject, as well as the 10th in the series of FHWA Geotechnical Engineering Circulars (GEC).
