Development adviser Turner & Townsend, which employs around 120 people in Salford Quays, posted UK pre-tax profit of £11.9m on turnover of £113.5m in the year to the end of April.
The group continued to grow outside of the UK with overseas revenue accounting for 54% of company sales.
T&T says it 'gained market share in the challenging domestic market', growing UK revenue by 6%. Overseas revenue growth, by contrast, was 35%.
Group revenue was £244.3m compared to £204.3m in 2011. Pre-tax profit was £23.0m, up from £15.7m last time.
Vincent Clancy, chief executive of Turner & Townsend, said: "This past year has been truly exceptional for us. Turner & Townsend has both exceeded its growth expectations and come of age as a truly global company.
"Our rapid growth owes much to the quality of our people, but also to the company's agility and its willingness to confront challenging conditions at home and pursue exciting opportunities abroad.
"We enter the new financial year confident that our strategy to expand into new markets and sectors remains robust. By constantly striving to improve execution and broaden capability we will continue to deliver great results.
"Just as many of our global clients are placing strong emphasis on emerging markets in Asia and South America, Turner & Townsend has built capacity in those regions and is now well positioned to serve its corporate clients on a cross-border basis.
"While we remain cautious about the impact of further economic volatility, we have a string of major infrastructure and natural resources programme opportunities in the pipeline and are confident that our diversity will reduce the impact of any easing of demand."
In the North West, T&T clients include Chester University, Blackpool Council, Manchester City FC and numerous schools.
