Piles set for Porth relief road


PILING FOR 3.5km of retaining walls for a relief road through the Porth town centre in south Wales is due to finish this month.

Bachy Soletanche's £1.3M work for main contractor Costain involves installing large diameter (600mm and 1200mm) bored piles on three retaining walls and minipiles on a fourth, to carry the Rhondda Valley relief road through the town.

Work is part of the £37M road scheme for Rhondda Cynon Taf County Borough Council, which aims to improve the north-south road corridor along the Rhondda Valley, while relieving the traffic bottleneck in Porth.

Bachy Soletanche contracts manager Barry Osborne, who is in charge of the project, said: '[There are] a number of geotechnical issues. Because we have been boring through boulders and into rock, we have needed to drill rock sockets into the bedrock up to 6m deep.' Bachy has also faced logistical obstacles working in the town centre, which has meant meticulous planning of work and the two rigs' movements. Piling began at the end of July.
