Housing hat-trick


GROUND ENGINEERING contractor Pennine has scored a hattrick of contracts on a new housing development in Scotland.

Housebuilders Taylor Woodrow, Robertson Homes and Stewart Milne enlisted Pennine's help to carry out ground improvement using stone columns for new homes at the Exelsior Development in Motherwell.

It was no easy task, said Pennine contracts manager Richard McKenna. 'With ground conditions varying widely from dense fill to alluvial clay with mudstone or sandstone bedrock, the projects presented a real hotchpotch of ground conditions.

'There's also a capped culvert running underneath the site - and the made ground varies in depth from 1.5m to 11m.'

Taylor Woodrow brought in Pennine in spring 2005 to prepare the ground for three blocks of threestorey 'ats and 73 houses.

Just weeks after completing the two-month project, Robertson Homes - which is building 138 houses - invited Pennine back to the same site.

Most recently Stewart Milne awarded Pennine a £150,000 contract that has just finished.

A total of 1515 stone columns were installed to depths between 3m and 11m. These improved ground bearing capacity to 125kN/m 2, enabling Stewart Milne to start building 43 houses on the site.
