Two Bobcat machines, a S650 loader and an E16 , are providing a
material handling solution for InMotion Construction and Trading Services on a
sub-contract involving soft strip and asbestos removal during the demolition of
the former Löhrhof shopping centre in Recklinghausen, Germany, for contractor
GL-Abbruch. Not wishing to judge before the case is heard, but this does
undermine Bangladeshi finance minister Abul Maal Abdul Muhith's repeated claims
that the corruption claims are "Baseless."
And I imagine there must have been
regret at the World Bank at having to take these steps. If it had gone ahead,
the Padma Bridge looked set to make a real difference to Bangladesh's
development.
The old centre, built in 1975, is being demolished to make way
for the new Recklinghausen Arcaden mall, with the demolition requiring the
removal of 70,000 tonnes of concrete, 30,000 lighting units, 18,750 square
metres (202,000 square feet) of floor coverings and 10,000 square metres 107,639
square feet) of dry walling.
But as encouraging as it is that the World Bank
is clamping down on corruption, debarments and withdrawing funds remain reactive
measures after bribes have been paid. I would like to see it move to a more
proactive approach, with all contracts awarded being open to public scrutiny,
including the method by which competing bids were assessed. It is an approach
advocated by the Construction Sector Transparency (CoST) initiative - the idea
being that with transparency in public procurement, there is nowhere for bribe
takers and payers to hide.
The
is being used to load materials both inside and outside the building, with its
low weight allowing it to be used on the upper levels of the structure. It is
used to load demolition debris into on site containers, both over the side and
by being driven inside. The E16 is predominantly being used indoors, where its
extending tracks allow it to fit through 1 m wide doors, and its width
adjustable stabiliser and dozer blades make it well suited for demolition
duties.
Steel-reinforced concrete uses rebar set in a grid pattern to provide
inner strength to concrete slabs and columns. The rebar is suspended in
approximately the centre of the concrete. When concrete begins to crack, the
rebar acts to retain pieces together but does not limit the spread of the crack
since the rebar can only provide structural strength within the concrete.
