Polluted coking works tackled
A Benelux consortium is to remediate a 100ha Chesterfield site which is one of the most polluted in western Europe. The Avenue Coking Works contract, worth between £40M and £80M, was let by the East Midlands Regeneration Agency (GE April 2005). The team consists of Dutch firms Sita Remediation and Volker Stevin and Belgian contractor DEC.
Lane Cove rebuilding starts
Rebuilding of Sydney's collapsed Lane Cove motorway tunnel exit ramp began last month. Contractor Theiss John Holland began boring through the concrete plug used to stabilise the zone that collapsed in November. It will create a retaining wall of 900mm diameter piles to isolate the area from the realigned tunnel route. Pressure grouting behind the wall should protect against further settlement.
One less bidder for Tyne tunnel
Contractors Nuttall and Vinci lost out in their bid for the £185M Tyne tunnel last month after Carillion pulled out of their consortium. The two remaining bidders are Connect North East (Balfour Beatty and Volker Stein Construction Europe) and a consortium led by Bouygues.
The road tunnel will run under the River Tyne between Howdon and Jarrow and provide the southbound carriageway for the A19 crossing.
