Blind Drilling Down Under
Australia's largest blind drilled shaft is a 14 ft diameter fresh air shaft for the Agnew nickel mine 500 miles northeast of Perth. It was drilled in one pass using air-assisted...
Role of a Standard in the Production of Drilled Shafts
The preparation of drawings and documents that describe the details of the installation of drilled shafts for a project requires an up-to-date standard. The role of the standard in the...
Geotechnical Perspective?Proposed Drilled Shaft Standard
In the writer's understanding, a standard is an agreed upon manual of practice and as such, sets the level of performance and attainment considered adequate. A standard is...
A Structural Engineering Perspective for Drilled Shafts
This commentary is an attempt to close the gap between the Building Code Requirements for Reinforced Concrete (ACE 318-83) and the design of drilled shafts. The context of design includes...
ASCE Drilled Shaft Standard: University Perspective
A critique is presented of the proposed ASCE standard on drilled shafts. Areas where major work is necessary relate primarily to the shaft design sections, establishment of loads, and...
Standards and the Contractor
The International Association of Drilled Shaft Contractors have written their own standards and have cooperated with other groups in similar activities. The author gives his ideas about...
Government Agency Perspective on Standard for Drilled Shafts
Relative to the proposed ASCE standard for Design and Construction of Drilled Shafts, the Tennessee Valley Authority (TVA) would be considered an 'owner'. However,...
