why not bring your local fire chief. We also have the lead

Our liaison work on timber strategy in Europe continues with
some excellent reports being received however on the political
front we are being outgunned especially on the sustainability
issue where the timber lobby has just held a very effective
exhibition aimed at MEPs and the Brussels civil service, supported
by publications. We have a massive amount of work to do to
reverse the position and continuing collaboration with common
interest groups in Europe is essential.

Our colleagues in The Concrete Centre are organising EC6 events
– see for details of these and several
new publications of interest to CBA members.

British Precast is holding its Concrete Fever conference at the
Athena Centre, Leicester on May 11th with a Safety Awards
dinner on the preceding evening – all CBA members are
encouraged to attend – we have a great programme of speakers.
