Currently Works have commenced near Osberstown, adjacent to the M7 Motorway, with earthwork
Operations progressing.

Ecology: As part of the process and in particular where new projects of this nature cross green field sites, the Contractor is required to consult with various government bodies, including the OPW, Fisheries etc… An Ecology survey was carried out, with mitigation measures developed where necessary.

At this stage, the focus is on preparing the Design and necessary approvals and consultations, to allow construction activities to commence in earnest, in the New Year.
