Feb 11 The manual is directed to geotechnical, structural, and construction engineers involved in the design and construction of pile supported structures.
TxDOT Research Library – Design and Construction of Driven Pile Foundation – Volume I
Because of this project, States have achieved substantial cost savings on major bridge projects. Several agencies have implemented computerized design procedures and developed load test result databases.
Approximately 41 State agencies have used the pile driving analyzer, many now use routinely. In the early s, many pile design and construction monitoring practices resulted in unnecessarily conservative designs because they were based solely on experience and tradition with little theoretical background.
Design & Construction Manual
Volume II covers construction aspects including dynamic formulas, wave equation analyses, dynamic testing, static load testing, Statnamic testing, the Osterberg cell, as well 103 pile driving equipment, pile accessories, and pile installation inspection. Volume I of the manual addresses design aspects including subsurface exploration, laboratory testing, static analyses as well as specification and foundation report preparation.
An NHI course has been developed from these workshops and is available. Field demonstrations were often performed in conjunction with construction projects, providing a direct comparison with existing State procedures and opportunities for cost savings. Phase I was a comprehensive classroom demonstration on the practical aspects and economic advantages of rational pile design and construction monitoring. Step by step procedures, workshop problems and solutions are provided to demonstrate use of the manual material.
TPC – Design & Construction Manual
The manual has been completed and published in two volumes. Phase II field demonstrations of modern construction monitoring techniques included a wave equation computer program, the pile driving analyzer, rapid methods of static load testing, and the saximeter inspection assistance instrument.
Goble Rausche Likins and Associates, Incorporated. Approximately 30 State agencies have implemented the wave equation computer program. Approximately 20 percent of all funds allotted to fhwx construction by the FHWA and State and local transportation departments is spent on pile foundations.
The results of each field demonstration were documented in a report that provided specific recommendations for improvement in State practices. To achieve this goal, the 977 was developed in different phases.
Based on a survey, six impressive changes occurred in State transportation agency piling hj during the life of this project: Pilot workshop presentations were presented in Portland, Oregon in Octoberand Tallahassee, Florida in November The manual is intended to serve as a practical reference on driven pile foundations.
Design of Bridges and Retaining Walls; I This manual is intended to serve a dual purpose, first as a participant’s manual for the Federal Highway Administration’s FHWA’s National Highway Institute courses on driven pile foundations and secondly as Hj primary reference of recommended practice for driven pile foundations.
Approximately 30 percent of agencies have made major revisions to their standard specifications for foundations.
