As the summer months approach, the level of construction activity will significantly increase throughout the Scheme.

Site clearance is now complete for the season and fencing has been erected site wide to secure boundaries to all active work fronts allowing the works to progress noticeably each day.

To date approximately 35,000m of fencing has been installed throughout the scheme.
