Mott MacDonald has acquired £120m-turnover water infrastructure specialist Bentley Holdings.
The move was described as a “natural progression” from the 15-year-strong Mott MacDonald Bentley joint venture.
Among MMB’s recent wins is its appointment to Anglian Water’s Integrated Main Works Capital framework, as revealed by Construction News in February.
This partnership currently gives sole Bentley Holdings subsidiary JN Bentley – which employs more than 700 people – 80 per cent of its income.
Mott MacDonald Bentley has secured AMP6 work for Yorkshire Water, Severn Trent Water, Anglian Water, United Utilities and Welsh Water.
JN Bentley owned 75 per cent of the joint venture.
In the year to 31 December 2013, Bentley Holdings had group turnover of £119m on which it made a pre-tax profit of £4.3m (up from £3m the year before).
MMB had turnover of £73.8m, up from £64.5m the year before.
The acquisition is the latest in a spate of M&A deals among engineering consultants.
Recent acquisitions include the UK’s largest engineering consultant Aecom’s announcement in July that it would buy URS Corporation for US$4bn (£2.3bn), while WSP announced earlier this month that it had agreed terms with Balfour Beatty to buy its US professional services arm Parsons Brinckerhoff for £820m.
In this year’s CN100, Mott MacDonald was ranked as the third-largest engineering consultant in the UK having posted turnover of more than £1.2bn in 2013, up 10 per cent year on year.
The firm was also named Engineering Consultant of the Year by judges at this year’s Construction News Awards.
Mott MacDonald chairman Keith Howells said: “The delivery model we have forged with our water industry clients continues to help them maximise value for their operations and their stakeholders.
“Now we’re looking forward to using our collective ingenuity to achieve ever greater benefits across the triple bottom line of social, economic and environmental value.”
JN Bentley managing director Paul Bentley added: “Joining Mott MacDonald will benefit our clients and also offers fantastic opportunities for the employees of both companies.
“The longstanding success of the joint venture is because we share the same culture and principles.
“Becoming part of the Mott MacDonald Group will allow us to develop further to meet the challenges we face and ensure we continue to deliver a first-class service for all our new and existing clients.”
