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
An NHI course has h developed from these workshops and is available. Several agencies have implemented computerized design procedures and developed load test result databases.
Because of this project, Thwa have achieved substantial cost savings on major bridge projects. Step by step procedures, workshop problems and solutions are provided to demonstrate use of the manual material.
The manual is intended to serve as a practical reference on driven pile foundations.
DESIGN AND CONSTRUCTION OF DRIVEN PILE FOUNDATIONS – VOLUME II
Pilot workshop presentations were presented in Portland, Oregon in Octoberand Tallahassee, Florida in November Volume I of the manual addresses design aspects including subsurface exploration, laboratory testing, static analyses as well as specification and foundation report preparation.
This manual is intended to serve a dual purpose, first as a participant’s 9 for the Federal Highway Administration’s FHWA’s National Highway Institute courses on driven pile foundations and secondly as FHWA’s primary reference of recommended practice for driven pile foundations. Volume II covers construction aspects including dynamic formulas, wave equation analyses, dynamic testing, static load testing, Statnamic testing, the Osterberg cell, as well as pile driving equipment, pile accessories, and pile installation inspection.
Design of Bridges and Retaining Walls; I Feb 11 Goble Rausche Likins and Associates, Incorporated. Approximately 30 percent of agencies have made major revisions to their standard specifications for foundations.
Based on a survey, six impressive changes occurred in State transportation agency piling practice during the life of this project: Field demonstrations were often performed in conjunction with construction projects, providing a direct comparison with existing State procedures and opportunities for cost savings.
The manual is directed to geotechnical, hu, and construction engineers involved in the design and construction of pile supported structures.
TPC – Design & Construction Manual
Phase I was a comprehensive classroom demonstration on the practical aspects and economic advantages of rational pile design and construction monitoring.
Approximately 41 State agencies have used the pile driving analyzer, many now use routinely. Phase II field demonstrations of modern construction monitoring techniques included a wave equation computer program, fha pile driving analyzer, rapid methods of static load testing, and the saximeter inspection assistance instrument. Approximately 20 percent of all funds allotted to bridge construction by the FHWA and State and local transportation rhwa is spent on pile foundations.
To achieve this goal, the project was developed in different phases. Approximately 30 State agencies have implemented the wave equation computer program. The results of each field demonstration were documented in a report that provided specific recommendations for improvement in State practices.
The manual has been completed and published in two volumes.
