More work on major projects caused revenue for Robertson Group to jump by a third from £565.4m to £752.4m in its last financial year ending 31 March 2018.
Executive chairman and founder Bill Robertson told Construction News: “At this point in time we’re doing four or five, whereas we had been doing one or two in the past.”
Among these are the £330m Aberdeen Exhibition and Conference Centre, the firm’s largest project to date, an £80m facility for Boeing and a £64m hospital in Orkney.
Pre-tax profit for the Scottish-based contractor increased from £26.1m to £31m last year as well, leaving the firm with a 4.1 per cent margin.
Robertson, which was the 22nd largest contractor in this year’s CN100, and the second-highest pre-tax margin among the top 25.
Mr Robertson said the firm has been able to grow its revenue without sacrificing margin thanks to its attention to detail on projects before they reach site.
“We probably spend more time on pre-construction than we do on building the project,” he said.
“I heard one of our boys say, ‘We’re almost writing the final accounts at pre-construction stage’.”
Finance director Stuart Roberts added: “We spend a lot of time looking at the information coming out of our business to make sure it’s as efficient as possible.”
Earlier this year Construction News revealed that Robertson Group would spin off its housing business into a new company, Robertson Residential Group.
Mr Robertson told CN the move allowed the board of the new company to “spend more time concentrating on the growth of the homes business”.
Robertson Residential Group is expected to generate around £200m of revenue in the current financial year.
Despite the housing business being split off, the revenue for the remaining group is not expected to fall.
“We think the Robertson Group turnover this year will be at the same level as the year just completed, without the homes business content,” Mr Robertson said.
He added: “We’re not interested in growing anymore top-line [revenue] wise at this point in time.
“If it comes along, fine, but it’ll have to come along with a bottom line [margin] too.”
Robertson Group has expanded from its traditional operating region of Scotland and the North in the last 12 months, taking on a 30-year framework contract with Eastbourne and Lewes council.
Mr Robertson indicated further regional expansion could happen if conditions are right.
“If we can create a long-term presence in an area, then we’ll go there,” he said.
