ABSTRACT

Trenchless construction is the use of construction methods to install and repair underground utility systems with minimum open cut excavation. This includes the use of pipe jacking, micro tunneling, horizontal direction drilling, and guided boring systems. This was adopted to replace the aging utility infrastructure and install new facilities, while minimizing disruptions to traffic communities and business, reducing environmental impact and lowering the high costs of pavement removal and site restoration. Critical areas of a trenchless application include crossing of conduits beneath highways, streets, railroads and other transportation arteries. Chapter one: Introduction which gives the general background of the study, statement of the problem, significance of the project, project objectives and scope of the project Chapter two: Literature review, which reviews documents, related to the study topic. Chapter three: Methodology which contains the primary and secondary data, quantitative and qualitative evaluations of trenchless method to the obtain best applicable Trenchless method to use for installation of the designed concrete duct and procedures how to install the duct. Chapter four: results, discussions and findings obtained in the test results and traffic count. Chapter five: challenges, the conclusions and recommendations.
