The firm has been winning business in its core sectors of defence and urban developmentIt has also been benefiting from the recovery in house-building, winning planning and enabling work.
Overseas, work has been won in Southern Africa, Bulgaria, Uzbekistan and the Western Balkans, notably a large scale project to advise SMEs in Croatia.
As a result, revenue is up a bit on last year – “reversing the negative trend of recent years”, the company said.
Chief executive Paul Hamer said: "We have had a good, strong start to the year, with encouraging progress in both our UK and overseas markets.
"Looking ahead, we are beginning to see signs that the UK government's investment in major infrastructure projects and its encouragement of the house building sector are having a positive effect on our core, front-end disciplines of planning and development. Overseas, we continue to build on our strong market position and maintain our focus on partnering to access new and emerging markets. Our strong track record in executing quality projects underpins our strategy of creating growth and becoming a global group."
