THE head of Balfour Beatty's construction business in Scotland expects the division to increase turnover by 8% this year when its success in winning public sector work will compensate for the dearth of private contracts.

Tim Clarke, divisional managing director, said Balfour Beatty Construction is in line to record revenues of £140 million in Scotland in 2012, up from £130m the preceding year.

The projected increase will be partly driven by revenues Balfour Beatty will earn under a string of contracts won from public bodies in recent months.

These include a £13m project to refurbish the Glasgow Royal Infirmary university tower.

Balfour Beatty won another £13m contract to refurbish two buildings in the Strathclyde University complex in the city.

It is also working on a £4.6m contract to build a power networks demonstration centre in Cumbernauld, North Lanarkshire, which is being developed by the university with Scottish Power, Scottish and Southern Energy and Scottish Enterprise.

The sums involved in all three contracts may seem small in the context of a business that had global revenues of £11bn in 2011.

However, Mr Clarke said big construction firms have been competing hard for contracts that might have been left to smaller players when there was more big ticket work to be had.

Mr Clarke said public sector work in Scotland played a key part in helping Balfour Beatty withstand the downturn in the private market since 2007. The construction business had annual turnover of £165m three years ago.

Mr Clarke highlighted the role of the Government's Scottish Futures Trust in bringing public contracts to the market.

"South of the Border things have come to a stop," said Mr Clarke.

However, he warned that conditions would be challenging over the next two years pending the start of work on a number of big contracts in the pipeline.
