ABSTRACT
As more and more municipalities and other governmental agencies engage in the use of trenchless technologies, questions are arising concerning the effect(s) that these operations may have on the surrounding infrastructure. Subsequently, requirements for monitoring and instrumentation are beginning to be implemented in contracts for projects employing trenchless methods. This paper presents an overview of various types of devices and installation procedures that may be employed for the insitu monitoring of Horizontal Directional Drilling (HDD) and Pipe Bursting projects. Lessons learned from a number of completed HDD and Pipe Bursting projects are also discussed along with suggestions for implementing a successful monitoring and instrumentation programme.
