Arup has reported a 69% rise in pre-tax profit and said it is in a “strong position” to weather the economic crisis.

The firm’s profit for the year to 31 March 2008 was £81m, compared with £48m the previous year. Turnover was up 27% from £572m to £726m.

It has cash reserves of more than £100m, up 54% on last year.

The UK accounted for almost half of the group’s turnover. Sales were £343m, compared with £275m last year.

Chairman Terry Hill said there were “signs of weakness” in some of the firm’s markets and in the US, turnover fell 20% from £76m to £61m in 2007.
