Liebherr’s tough team

A fleet of equipment from Liebherr-Rental has been playing a crucial role in a £120m project to improve water quality in Ayrshire and parts of East Renfrewshire.

The first phase of the Scottish Water project started in May and calls for a 13-mile mains pipeline running from near Newton Mearns to the Waterside/Fenwick area to benefit more than 200,000 people and businesses.

One of the contractors working for Caledonian Water Alliance (the joint venture of Morrison Utility Services and AECOM) is Enviro-Clean. The East Kilbride company has experience on Scottish Water’s smaller-scale projects such as mains replacement and repairs but the new contract demanded the deployment of larger equipment – and logistics and operations manager Jimmy Brown knew exactly where to find it.

He had previous experience of using Liebherr kit and Liebherr Rental was his first port of call as he set about assembling the specialist fleet required. He takes up the story: “We were contracted to undertake the excavation of two pairs of pits to allow the main to cross the A77. Ground conditions were not easy on the job as the surface layers consisted mainly of peat with a deep underlying layer of rock.”

Once the peat was stripped and stockpiled for reinstatement, the rock was exposed but blasting it was not an option because of a nearby main road. The answer was a package of equipment arranged through Liebherr-Rental’s national rental manager Ken Buckley. It included a 40-tonne PR 764 dozer to rip out the material and a 56-tonne R 956 excavator to feed it into a fleet of dumptrucks.

“We knew the Liebherr machines were strong bits of kit but they really excelled on this tough job,” said Brown. “Despite us pushing them to the maximum they performed very well.”

As well as the two bigger machines, Enviro-Clean hired four additional excavators – a pair of 35-tonne R 936s, a 22-tonne R 922 and a 15-tonne R 914 Compact – to carry out reinstatement and help in excavations for the piling sub-contractor. Completing the Liebherr contribution was a PR 736 dozer to reinstate the surface layers.
