The contract was for flood prevention works in and around the town of Galston, comprising of steel reinforced retaining walls, gabions, CFA (bearing piles) & sheet piling works to protect the banks and properties of the Burn Anne. Sheet piling, steel reinforced retaining walls and attenuation bunds were constructed along the banks of the River Irvine Adjacent to the A71. This contract required a high degree of sensitivity due to the close proximity of residents and businesses, coupled with the environmental issues associated with flood prevention works.
