A £120 million work book and increasing staff numbers has seen the Robertson Group expand its Tayside operation with the opening of a new office.

The infrastructure firm officially opened Robertson House in Dundee on Thursday, October 29 with the new office home to 56 staff across its construction, facilities management and special projects divisions.

The expansion of Robertson Tayside comes during a significant period of growth for the group, which celebrates its 50th anniversary next year.

Robertson Group founder and executive chairman, Bill Robertson CBE, said: “While Robertson Tayside’s new office is based in Dundee, in opening Robertson House we have made a firm commitment to the communities of Tayside, Perthshire, Angus and the wider area.

“With a focus on creating a strong, skilled local workforce and vibrant construction sector across the east coast, Robertson Tayside has become a significant part of our growth plans.

“We have started on a very firm footing with more than £122m of work underway already, however this is not the end of our ambitions and we look upon our success so far as offering a very solid platform for further growth.

“With a further £120m of work in the pipeline and £50m of potential work identified by our team, we are already on course to deliver this.”

Among the contracts already being delivered by Robertson Tayside are the £30m construction of a new campus for Harris Academy in Dundee, the £25m Brechin Community Campus project and the £15m refurbishment of Perth Theatre.

Derek Shewan, chief operating officer of Robertson, added: “We have a long history in Dundee, Tayside and the wider area, including building and maintaining six primary and two secondary schools for Dundee City Council. However, the opening of our latest office in Dundee, Robertson House, is a significant milestone for the company.

“Our current order book is very encouraging and underlines the fact that we are largest contractor in the Tayside area.

“Our regional business model facilitates the development of local teams in areas where we operate. Which in turn allows to work more closely with the local supply chain and the communities within those areas.”

The Stirling-based Robertson Group, which employs over 1,600 people across the UK, is now in the final year of a five-year plan, which has seen it straddle the recession and produce double-digit growth despite the challenging business environment.

In March, it had announced its turnover had increased by 20 per cent in the last financial year to £300million – and was on track to double that figure over the next three years.

In the 12 months ending March 2015, Mr Robertson led a programme of growth and diversification, targeting higher value workload and resulting in the creation of seven new businesses and further expansion across Scotland and the north of England.
