Bison Precast has designed, manufactured and supplied a unique retaining wall system, made up of more than 200 bespoke precast concrete units, which has been used in the construction of a permanent access road to a new electricity substation for the Hornsea offshore wind-farm in Killingholme.
The precast units were specified to support the holding platform of the road structure, while also controlling the water in the ground at the site, which is low-lying and on the Lincolnshire coast.
Joel Chadwick, Site Agent for Balfour Beatty, said, “We required a purpose-built retaining wall system for this road, as it was situated in complex terrain and the surrounding water table called for a system that would control the high flow of water beneath the road.
“The system also needed to be strong enough to bear the weight of large vehicles carrying abnormal regularly travelling to and from the substation.”
Bison Precast’s specialist precast team, based
at the firm’s facility in Somercotes, used their expertise to create a unique
bespoke system for the access road, based on previously successful
installations at similar coastal sites.
Joel continued: “The team at Bison Precast, which Balfour Beatty
has worked with on prior occasions, met our needs swiftly and to specification,
and the system was successfully installed relatively easily and ahead of
deadline. I’d recommend Bison Precast's experts without hesitation, as they
stayed on top of the job, providing essential details for the application when
needed.”
