Progress at London's Major Waste Contract
4 February 2010
With the Riverside Resource Recovery Limited (RRRL)
Energy from Waste Facility at Belvedere now looming large along the
south banks of the River Thames, the Cory Environmental Limited tug
/barge crews are eyeing with anticipation the day when they can
berth at the facility.
Works progress at pace with delivery of the first waste and
subsequent hot commissioning due to commence later in the year and
a final take over certificate obtained before the middle of May
2011. Construction of the 270m long jetty and 200m long access
bridge is virtually complete and first of the two large waste
container handling cranes manufactured in Scotland has been
delivered by barge from Tilbury docks and is being erected on the
jetty.
During 2008 nearly 2,500 CFA piles (25,000m3 concrete) were
installed for the foundations and in 2009 over 25,000m3 of
structural concrete placed in pile caps, floor slabs walls and
columns of which 4000m3 was poured in the non-stop slipform
operation to construct the waste bunker. The bunker will store the
delivered waste until placed into the feed hoppers and subsequently
into the three Boiler grates.
Three boilers will then produce steam to drive the single
turbine which will generate over 66MW of electricity. This
electricity will be distributed to the national grid through a new
substation currently being built on the site.
Out of a total of 5,700 tonnes, over 2,200 tonnes of steel is
being erected for the building envelope and structural supports and
the external steel cladding and roof panels, 50m height at its
highest point, are now being installed.
The Costain design and build contract also includes the building
services for the plant and the installation of these and the fit
out of the accommodation area, control room and electrical rooms is
well underway. The drainage, roads, hard standings, flood defence
works and landscaping will all be completed in 2010.
One of the many challenges on the project for the Costain team
is the successful coordination of all their activities with those
of VonRoll Environmental Ltd, the EPC contractor for the project.
The logistics of managing the many deliveries with over 700 people
now working on site has also been a difficult, but a successful
challenge.
Some 1.7million Costain manhours have been worked to date with
much on site training of the Costain workforce and those of our
supply chain. Frontline Supervisor, Behavioural Safety, Working at
Height to name a few also with Drugs and Alcohol testing and a
programme of health screening which has just been completed.
