GEOCONSULT LAST month failed to get the £500,000 fine resulting from its part in the Heathrow Express tunnel collapse overturned by the Court of Appeal.
The court earlier refused the Austrian ground engineering firm leave to appeal against the guilty verdict handed down after the Health & Safety Executive's successful prosecution.
Geoconsult chairman professor Johann Golser said the firm would meet its lawyers in London to discuss the outcome .
Geoconsult and Balfour Beatty were found guilty of failing to ensure the safety of their employees and others following the 1994 collapse.
Balfour Beatty was also fined £1.2M for its part in the disaster (GE March). Both firms were ordered to pay £100,000 towards costs.
