Arch Design

Our precast concrete arch structures are bespoke products with each arch being designed to suit a particular projects requirements.

The geometry of each arch is optimised to minimise the in service bending moments to provide the most efficient and economical shape.

The width of individual arch units is optimised to provide the most efficient transportation and handling requirement.


A state of the art report 'Precast Concrete Arch Structures' was published in 2009 by the Concrete Bridge Development Route. This report provides guidance on the use of precast concrete arch structures including TechSpan, and was developed to enable the Highways Agency to continue to benefit from the use of precast arch structures.
