ASCE MOP 133
Pilot Tube and Other Guided Boring Methods
|Publication Date:||1 January 2017|
This manual of practice was prepared by the Task Committee on Pilot Tube and Other Guided Boring Methods of the ASCE Committee on Trenchless Installation of Pipelines (TIPS), as part of the Utility Engineering & Surveying Institute (UESI). The manual describes the current pilot tube and other guided boring methods used by engineers and construction professionals in designing and installing pipelines to a design line and grade under roads, railroads, streets, and other constructed and natural structures and obstacles.
This manual of practice has been created by a group of engineers, owners, suppliers, manufacturers, and contractors fully knowledgeable of the method and its use. This manual takes into account many of the advances that have occurred over the years in the guiding of trenchless methods. Many of the sections provide a summary of the state of the industry as of 2016. The task committee acknowledges that the technology continues to change and that changes in construction continue to develop.
Sections have been written assuming the reader may be new to the various construction methods included in this manual. No document including this one can encompass all of the issues on a particular pilot tube or other guided boring project. Improvements in best practices and technology continue to evolve so quickly that consideration of this manual on any project must take into account not only the specific characteristics of the particular project but also further improvements in best practices and technology.
The engineer of a pipeline project is encouraged to consider all trenchless methods before concluding that the pilot tube and/or other guided boring methods are the most suitable construction methods available. Manuals and reports on engineering practice (known as MOPs) have been written by ASCE for different construction methods. A list of useful references is provided at the end of Chapter 1.
If the engineer responsible for the pipeline project does not have a strong background in trenchless design, an engineering firm that specializes in trenchless designs should be consulted to provide a peer review early in the planning/design process to help ensure good design choices are being made.
