This project involved the replacement of an under-track culvert on the Limerick to Tuam rail line with 4 new 2.4m x 2.4m precast concrete box culverts. The works were carried out in a short time frame of just 36 hours in order to facilitate a the re-opening of the railway line. The works carried out included ground-works, precast installation, waterproofing of units, installation of gabion units and relaying of railway tracks.
A steel pipe was installed underneath the railway line by use of pipe ramming. We blocked up the existing culvert and pumped it with concrete. Two precast headwalls were installed, one on either side of the new pipe. A roadway was made down to the pipe ramming location and also an access pit created for to facilitate pipe ramming equipment. We also cleaned existing drain down to lake and carried out site clearance work.
