Construction consultancy firm Turner & Townsend saw its turnover pass the £400 million mark as the company’s global footprint helped it to maintain solid growth over the last year.

Turnover was up 8% overall to a record £409 million from £379.9 million the previous year, while profit after tax rose by 9% to £30 million for the year ending April 30, 2016.

Excluding revenue from subcontractors, Turner & Townsend’s net revenue was up by 7.9% overall to £378.2 million from £350.5 million the year before.

The company employs almost 4,300 staff across its 97 offices throughout the world and has now enjoyed six straight years of revenue growth, while profits have increased threefold over the last four years.

The senior management of the firm says that the success is down to its geographic footprint and diverse activity spread through three core sectors of natural resources, infrastructure and real estate.

Last year’s harsh fall in oil prices was balanced out by the company’s Middle East operation through increased real estate and infrastructure work as total revenue in the region grew by almost 25%.

Australia and New Zealand operations saw similar growth, while there was a growth of 9% in Mainland Europe. UK and Ireland turnover rose by 14% to a record £180 million, with revenue also increasing in Latin America and Africa.

The firm reported growth in global real estate revenue throughout its sectors, with a 15% increase up to £196 million and infrastructure up by 16% to £123. This offset a fall of 20.4% in the natural resources sector.

Throughout the year, commissions secured included work on the UK’s HS2 rail line, US airports in Dallas and Houston and Australia’s biggest ever hotel and residential complex, The Jewel.

Vincent Clancy, Chief Executive at Turner & Townsend, commented: “Our achievements are a testament to the strength of our business, despite a backdrop of significant volatility.”
