Financial Close on Kent Grouped Schools PFI

Costain is pleased to announce that as part of the Kent Education Partnership
consortium ('KEP'), it has reached financial close on the £92 million Kent
Grouped Schools PFI project for Kent County Council.

KEP is made up of Costain Education and Construction Limited, Bilfinger Berger
BOT Limited and William Verry Limited.  Costain will be responsible for the
design and construction of three out of a total of six schools, with a value of
approximately £46 million.   Construction on the project commenced this month.

Andrew Wyllie, Chief Executive of Costain, commented:

'We are delighted to have reached financial close on this sizeable project.
This is the second PFI contract we have secured in the education sector within
the last three months following the success of our Ealing Schools project
announced in July.   Education is a key market for the Group as we continue to
focus on sectors in which we have a well developed skills base and extensive
experience.'
