In the directors' report, the company hinted that it would make few radical changes to its structure over the next 12 months.
The report said: "The group will continue its existing activities and will pursue new business activities as they arise."
More than half the group's turnover comes from UK operations. America accounts for £62.3m of turnover, and Asia £84.6m. Arup also has operations in continental Europe and Africa.
Much of the company's spending is on staff costs. Wages and salaries came to £188.6m – £22.4m more than the previous year. Arup now employs 6132 people; on 31 March 2001 it employed 5512 staff.
Company accounts for 2001 were restated after a group restructuring, which resulted in the acquisition of a subsidiary. The figures were therefore restated with the inclusion of the subsidiary's finances for comparative use.
