NASSCO is pleased to offer the following Specification Guidelines as a service to our industry. These Guidelines have been prepared by NASSCO and have been peer reviewed by a committee consisting of suppliers, installers, engineers and system owners. It is our hope that you will use these guidelines as a reference point from which you will apply your own engineering judgments as project specific details are considered. It is out intent to add to, but not replace, the valuable input from professional engineers and experienced contractors while advancing the trenchless technology experience.
