Contactor JV 4Delivery, comprising Veolia Water/Costain/MWH, has broken through on its 2.6km long drive between Peacehaven and Portobello on Southern Water’s US$477M Cleaner Seas for Sussex scheme in Brighton, UK. The JV began the drive in July last year using one of two 2.4m diameter Lovat EPBMs currently boring the project’s 11km of tunnel.
Having completed this section of tunnel, the TBM, named Hollyblue, will now be lifted out of the ground and return to Peacehaven to start on her journey to Friars Bay.

A conference designed with the expert in mind, Cutting Edge's unique offering of specialized technical information won't be found anywhere else ... 29th to 31st October - Register TodayBen Green, Southern Water’s project manager, said: “Most people who see the work we are doing on our sites above ground don’t realise the hard work that is also going on underground. This is another significant milestone for the project which once complete will bring cleaner seas to Sussex.”
The second of the two Lovat TBMs, Alice, is also currently underground where she is working her way to Portobello from Ovingdean having already completed a section between Ovingdean and Marine Drive Pumping Station.
The other remaining tunnels will be created using pipejacking.
Supplier 4Delivery began work in the summer of 2009 and the project is due for completion in 2013.
