Project Overview
The project was located in Huntly in the Northeast of Scotland and involved the raising and strengthening of existing flood defence earth bunds along the bank of the River Deveron and the Meadow Burn which were prone to flooding affecting the local community.
Construction of Culvert outfall into River Deveron required the existing flood defence to be maintained at-all-times. This required staged construction of the headwall and culvert by constructing a temporary earth embankment to allow first stage then relocating to permanent position to allow final stage.
A 250m length of bund incorporating 2x reinforced concrete headwalls with a connecting pre-cast concrete culvert through a 250m length sheet pile wall was constructed under the Reservoir Act which required specialist approval and monitoring of the work.
