Carbon Reduction Plan

Bunns Lane Culvert Extension

Approached by the incumbent contractor, we were asked to assist with the design and supply of a culvert extension for Bunns Lane, Wiltshire. Having considered alternative products AQUA TDX culvert extension pipe was chosen in conjunction with a bespoke fabricated connection piece, the reasons for this were: Speed of installation is increased leading to greater productivity on site Cost of hiring shoring/shuttering materials and specialist equipment is reduced/ no longer applicable. Culvert extension to the new headwall is easily achieved with only two pieces. Solution A bespoke connection piece was fabricated in our factory to enable a positive connection between the existing culvert and the new extension piece. Due to reballasting being required to address alignment issues over a number of years the current track position is much higher than when the culvert was originally constructed. As a result of this the embankment slope is much steeper than would be ideal and is causing stability issues. Additionally the culvert head and wingwalls have also suffered damage over the years resulting in a breakdown in the structural integrity of
