Implementation costs analysis of constructing a medium- and low-pressure gas network with connections – open-cut vs. trenchless    
In USA there was published a study titled "Cost and Risk Assessment for Horizontal Directional Drilling Compared to Open-Cut Method in Urban Environment". It was conducted among contractors and it indicated that 68% of them identified difficult geological conditions as the most important cost and risk factor. The second most important factor in the study was the access to the construction site - 46%. Having a proper access to a construction site can help reducing the time spent on maintenance.
Social costs, mobility constraints (ie, restrictions, control) were listed as another important factor - 39%. As far as the open-cut method was concerned, 61% of the contractors thought that the condition of the soil was the most important factor. Traffic problems were the second most important problem for the construction, because in urban areas traffic lanes are usually closed or passage is limited. An analysis of the costs of implementation of the medium- and low-pressure gas networks with connections (open-cut vs. trenchless method) will be presented in the above described context.
