Consultant Atkins has increased its energy division headcount by 15% responding to a buoyant market, the firm announced in an interim management statement released this week.
The firm said its rail business is improving due to HS2 work and its water and environment division through work won under the AMP5 water framework.
Highways and transportation are also improving thanks to recently-awarded design work on the M25, according to the statement.
Contract negotiations in the Middle East have affected short-term profitability, but the consultant does not expect this to affect staffing levels.
Atkins said it was trading in line with expectations and hopes to post net funds of over £110M when it releases it full results on 31 March.
