Case Study

Banagher Precast Concrete was contracted directly by Irish Rail to manufacture and supply 42 Precast Concrete Culvert Units, 11 Ballast Retainers and various other precast elements to UB313 near Buttevant in County Cork.

The Culvert Sections were precast in two pieces a top unit and a bottom unit, to facilitate transportation to site. When the units were placed together on site they measured 6.5m wide by 4.8m high internally. Each top or bottom section weighed 27 tonne. The 11 ballast Retainer weighed in excess of 21 tonne each.

All the waterproofing was applied in our factory prior to delivery thus reducing the working hours required on site. The programme was extremely tight and weekends were worked at our Factory to ensure the units were delivered on time.  The replacement of the bridge was undertaken by Coffey Construction and was carried out over a weekend rail possession.  There is a time-lapse video of the bridge replacement, which can be viewed by clicking the link below, and is well worth the look.
