Coming together of the two companies’ teams in the city marks a major milestone for the merger in the UK, WSP said.
WSP Parsons Brinckerhoff has 32,000 people in around 500 offices across 39 countries, but Bristol becomes the first UK city where the two businesses operate from the same office.
The Bristol office will have around 260 staff.
WSP bought Parsons Brinckerhoff from Balfour Beatty last year for £820m, representing a Canadian-US tie-up. Parsons Brinckerhoff is originally an American firm; WSP is Canadian, since it was acquired by Genivar in 2012. Last year Genivar rebranded to adopt the WSP name for itself.
Mark Naysmith, WSP Parsons Brinckerhoff UK COO and MD for property, transport and infrastructure, said of the new Bristol office: “Combining our teams is a clear demonstration of the combined strength of our business and our intent to integrate quickly. This is a complementary merger of minds and talent and there is huge potential for growth in Bristol and the southwest for our services, working on local, national and international projects. Integration provides a great opportunity for our people to broaden and develop their careers.”
