“…This new technology has been used to solve underground problems without excavating large quantities of soil (Iseley et al 1999). The need for TT methods has become prevalent due to the inherent problems associated with the open-cut method, especially with respect to environmental impact and traffic disruption (Atalah et al 2002, Gangavarapu 2003. There are several TT methods, which are available in the market, such as micro tunnelling, pipe bursting, auger boring and directional drilling.…”

Canadian municipalities have noted that 59% of their water systems and 68% of their sewer systems required repair. To rehabilitate, replace or construct a water or sewer pipeline, several methods can be used: open-cut or one of several trenchless technologies (TTs). The selection of the method positively affects the surrounding environment. Therefore, the impact on environment (IoE) becomes a vital concern in selecting the appropriate construction or rehabilitation method for water or sewer pipelines. The research presented in this paper aims at developing an IoE model that compares the open-cut and TT methods. The IoE factors and their related data are collected, analysed and categorised based on literature review and expert opinion. Two models are designed in order to assess the IoE of the open-cut and TT methods. Results of the open-cut technique show that the impact on social factor has the maximum relative weight of 0.36; however, the impact on project characteristics has 0.33 and on environment has 0.30. The impact of TTs on project characteristics has the highest weight of 0.38, in which social factor is the lowest (0.28). The IoE value, using the open-cut method, is 0.4739; however, its value using the TT method is 0.3346. The developed IoE model shows robust results in quantifying the impact on environment of underground utility work. This research is relevant to both industry practitioners and researchers. It develops models to determine the IoE for the open-cut and TT methods. They are also beneficial to the municipal experts.

“…The long-term performance of fiber networks is important because of the significantly high costs of FO deployment and the massive impact of broadband network failures on communities and businesses (Crandall et al 2007;Holt and Jamison 2009;Czernich et al 2011). Typically, open-cut methods result in significant costs and disturbances to the community and environment (Atalah et al 2002;CSMG 2010). Furthermore, high construction costs are associated with mini-HDD in addition to the risks of hydraulic fracturing, bore collapse, and loss of circulation, as well as issues arising from steering limitations in cohesive soils (Osbak et al 2012).…”

Micro-trenching is an innovative and discreet utility installation method that includes the creation of a narrow trench to lay cable or conduit in the ground. To investigate the functionality and durability of micro-trenching in cold regions, two micro-trenching technologies were employed and monitored over the course of two winters in a parking lot in Edmonton, Alberta, Canada. During construction, productivity rate and generated waste material were studied. The installation's physical integrity and optical performance were also evaluated during the monitoring period. Physical integrity was assessed by monitoring the conduit location using ground-penetrating radar (GPR), and an optical time-domain reflectometer (OTDR) test was conducted to determine attenuation in performance. Results indicated that the installation experienced undesirable upward and downward movements in sections with high traffic load, which may be prevented with a more effective reinstatement method. However, the fiber's optical performance was not affected.
