 AR. Revenue presented in Beaton450 for consulting engineering firms is based only on consulting and related services, because most consulting engineering firms are diversified and include contract and/or manufacturing businesses
 AH. Headcount adjusted to revenue

Definitions:

Globalisation ratio: Calculated by dividing the firm’s offshore offices by total offices
Headcount: Number of professional staff

Beaton450 research method.

Beaton Capital conducts the research independently.

Beaton Capital compiled the table by reviewing, comparing and independently drawing conclusions on global revenue, global headcount, number of offices, mergers and acquisitions, joint ventures and alliances, new offices opened, and country of origin.
Our sources are publicly available professions-specific league tables, media reports and over 500 firms’ websites.
Revenue is stated in US dollars. For some date points estimates based on proxy analysis have been used.
