Contract Value


The works consisted of the construction of two fish ramps on the River Avon at Ferniegair and Millheugh weirs near Hamilton, Lanarkshire.


Limited access to the working areas required the construction (and removal upon completion) of extensive temporary access roads. Once access was gained, temporary coffer dams were installed to enable the fish passes to be constructed.

The fish passes are constructed of precast concrete blocks, which are dowelled into the existing rock in a folded pattern to minimise the footprint of the works.

Working within the river required substantial environmental measures to ensure that there was no pollution/contamination of the watercourse whilst dealing with a high range of water levels that react rapidly to rainfall.

High levels of collaboration and communication with the client, Regional Council, local care home ad residents were key to ensuring the impact on the river and the community were minimised throughout.
