Aggregate Industries has appointed consultant Waldeck to design and detail three precast concrete plinths for a memorial structure at Bethnal Green Tube station in east London.
The memorial will be to those who died in the Bethnal Green Underground Station disaster - the worst civilian disaster of World War II - when 173 people were killed in a crowd crush during an air raid alert.
Arboreal Architecture director Harry Paticas initiated the Bethnal Green Memorial project six years ago.
So far the local community has raised £256,000 to pay for the first phase of the project which includes ground work, landscaping, benches, plaques and precast concrete plinths.
The Stairway to Heaven Memorial Trust appointed Aggregate Industries to manufacture the concrete plinths, the biggest of which will weigh 10t and is 7.5m high and 1m wide.
One of the three polished concrete plinths acts as a support arm for a hollowed out laminated teak stairway.
This echoes the shape of the entrance stairway to the Tube station directly below and depicts the volume of space in which people died.
Waldeck is using the latest Tekla Structures Building Information Modelling (BIM) software to create detailed 3D models of the precast concrete elements.
Using this software Waldeck’s team of structural engineers can interrogate the design and eliminate problems at an early stage, reducing scope for design and fabrication errors.
The 3D model also enables the manufacturer to produce a precise mould. Waldeck director John Holroyd said this is particularly useful when working on a project of this nature.
“The Bethnal Green Memorial is a challenging project because of the unusual shape of the design. The plinths have sloping planes and there are no straight angles,” he said.
Work starts on 1 March and will take approximately three months.
