Breffni’s strength lies in the ability to easily adapt to evolving circumstances with a large and expansive fleet of plant and equipment used to facilitate the smooth running of operations - a list comprising artic and tipper trucks, track and mobile excavators, dozers and dump trucks, crushing and screening machinery and a number of smaller plant items. Breffni also uses fleet to coordinate civil engineering and construction projects and other related business ventures.

A significant project for Breffni was the DART upgrade which involved Mast Base Construction and Mast Erection on the entire Dublin network and liasing with many operators involved in construction and bridge erection.
