CARILLION HAS revealed it is embroiled in a £17M claims battle on the £200M River Lee immersed tube tunnel project in Eire.
The company is also involved in claims negotiations on the Canary Wharf and Canada Water stations, part of London Underground's Jubilee Line Extension project, as well as on the Copenhagen Metro project.
The news is disclosed in Carillion's prospectus, published last week, as Tarmac unveiled plans to demerge its construction businesses and concentrate on heavy building materials (see feature, page 10).
The claims on the River Lee scheme relate to extra work blasting 70,000m3 of limestone to form sea defences and a bund wall, as well as the dredging of 500,000 m3 of silt.
Subcontractor Dredging International has lodged claims with the main contractor, a joint venture between Carillion and PJ Walls (an Irish contractor 50% owned by Tarmac's former contracting arm). It has in turn registered claims with the client, the Cork Corporation.
The claims total £17M, more than double the original contract price of £8M. Carillion said the claims will not have an adverse impact on the company.
