This 300m long underpass structure carries the Lehaunstown Road over the Luas line at Cherrywood, Co. Dublin.
The structure utilises a double “T” precast walling system built on a spread foundation and an integral bridge deck with precast concrete bridge beams and track slab. The precast wall system, erected in vertical panels, allowed for high efficiencies in speed of construction and repeatability to be achieved.
The double “T” precast concrete wall system utilises a circa 160mm front flange with 800 – 1,200mm deep ribs. This structurally provides a highly efficient solution, minimising concrete volumes and hence reducing substantially the carbon footprint for this large structure.
An in-situ concrete bank seat is located at the top of the precast wall system to allow transfer of moment forces between deck and wall, hence ensuring full integration and avoiding the need for any joints.
At PUNCH, we understand the value of education. That’s why we support our staff who wish to undertake further education and training. We encourage staff members to maintain their Continuous Professional Development (CPD) accreditations with Engineers Ireland. We also continue to offer training in sustainable design and construction through seminars, in-house lectures, and external training programmes. We promote the achievement of professional titles with institutions such as Engineers Ireland, the Association of Consulting Engineers of Ireland, the Institute of Structural Engineers, and the Institute of Civil Engineers.
