This paper describes the state-of-the-art review for trenchless pipeline rehabilitation being conducted under the Construction Productivity Advancement Research (CPAR) program. For the purpose of this study, the existing trenchless rehabilitation methods will be classified into six groups: cured-in-placed pipe (CIPP), sliplining, in-line replacement, deformed & reshaped, point source repair, and sewer manhole rehabilitation. For each group, specific rehabilitation procedures will be provided and advantages and disadvantages of each method will be discussed. This information is being obtained through literature search and survey of manufacturers, utility owners and contractors of sewer rehabilitation products and services. However, the state-of-the-art review provides additional information such as an overview of design techniques with plastic pipes, the rehabilitation costs as a percentage of new installation and also to the amount of open-cut required for different methods. The intent of this state-of-the-art review is to provide information on capabilities of existing trenchless rehabilitation systems to assist design engineers and city officials to plan and conduct pipeline rehabilitation when dealing with a specific system.
