Abstract

The deterioration of municipal underground infrastructure systems and a growing demand for utility services have increased the necessity for more efficient installation, inspection, repair, rehabilitation, and replacement of underground utilities. Taking social and environmental factors into account, open-cut methods have adverse impacts on the community, business and commuters due to undesirable pollution and traffic disruptions. Trenchless technologies that are used to repair, upgrade, replace, or install underground infrastructure systems with minimum surface disruption offer a viable alternative to existing open-cut methods. The objective of this paper is to explore a methodology of trenchless construction for an underground infrastructure, which would be more efficient by review of various trenchless technologies that had been completed so far.

It is suggested that decision makers shall combining these costs with direct capital costs so that the best alternative is selected, which in certain cases, we can make trenchless technology the most economical alter native. Moreover, productivity, workers’ safety, and structural issues have shown that trenchless technology is a more efficient method for underground infrastructure systems. Managerial aspects are also considered for the best accomplishment of this technique. Asset management is one of the best techniques for management of trenchless technology productivity.
