Structural Concrete Alliance
announces 2018 award winner
The Structural Concrete Alliance
has announced Volkerlaser Ltd as
the winner of the 2018 Structural
Concrete Alliance Award for Repair
and Refurbishment for its repair and
strengthening of a marine quayside
at King George Docks, Hull. The
award was presented by broadcaster,
Huw Edwards, at the Concrete
Society Awards Dinner held at The
Royal Lancaster Hotel, London on
Wednesday 21st November 2018.
The repair and strengthening works to
12 Quay at King George Docks in Hull
presented an extremely challenging
project for Volkerlaser. It involved
the use of concrete repair, sprayed
concrete, cathodic protection and
Carbon Fibre Reinforced Polymer
(CFRP) strengthening, to provide a
unique solution.
Access to the quay was restricted by
various factors, including; weather
conditions, port activity, tide times
and most importantly water levels.
The water level to the beam soffits
was only 500mm, increasing to
900mm at the deck soffit, requiring
the development of a bespoke access
craft.
Since standard CFRP solutions were
not feasible, Volkerlaser worked with
Curtins to develop a design that
used a combination of CFRP wrap,
plates and rope (known as fiocco) to
replicate the structural workings of a
truss beam. Hand placed and sprayed
concrete repairs were undertaken
and galvanic anodes were installed
within the repairs to provide long term
protection.
Second place was awarded to Kier
Design Services - Highways for its
innovative delivery solution to
complete extensive concrete repairs,
re-waterproofing and resurfacing of
the A38M – the main link between the
M6 ‘Spaghetti Junction’ and the centre
of Birmingham.
