Costain Group PLC
('Costain' or 'the Group')


Consortium for M25 DBFO


An Anglo-French consortium, comprising Costain, Carillion, Laing Roads, Mouchel
Parkman, Jacobs-Babtie, VINCI and ASF has been formed to tender for the Highways
Agency's 30-year design, build, operate and finance programme for the M25.


The Preferred Bidder announcement is expected in autumn 2007. The construction
works will be carried out by a joint venture led by Costain and VINCI.


The members of the consortium are variously engaged on existing M25 projects.
Of more than £600m of road contracts secured by Costain this year, nearly £200
million involves M25-related work.
