What this covers

  • Letterkenny Northern Network Project - Ground Investigation Contract

    The Letterkenny Northern Network Project aims to develop the transport network to the North of Letterkenny Town. This strategic piece of infrastructure aims to provide a new enhanced connectivity link between Glencar and the Knocknamona Roundabout, reduce traffic congestion, support compact growth, and encourage modal shift. The scheme aims to provide a new road realignment of the existing L1152-1 Windyhall Road, include provision for segregated pedestrian and cyclist active travel facilities throughout the scheme, with reallocation of road space to accommodate this on existing sections of road. The works will involve carrying out a number of boreholes (rotary open-hole drilling and core holes), slit trenches, trial pits, pavement cores, dynamic cone penetrometer. The boreholes are provided to determine sufficient sub-ground conditions and depth to bedrock below proposed foundations. Trial pits are provided to obtain a geological description of the first meters of soils, to carry out in situ testing and to obtain soil samples. Pavement cores will provide information on the type of existing pavement at tie ins of the proposed road with the existing roads. Geophysical surveying can be used to aid in the detection of buried utilities. Slit trenches will provide information to establish the line, level, dimensions and type of services. Dynamic cone penetrometer will provide information about the soil strength and stiffness at areas of difficult access. Traffic Management will be required to provide a safe working environment for all works on or in the vicinity of the public roads. The plans showing the extent and type of work to be carried out at specific locations are indicated on the drawings included within the scope.
