Scarborough Lane Retaining Wall

Ice Excavation has successfully completed the deconstruction of existing damaged retaining walls and reconstructed a gabion basket retaining wall as well as repairs to existing dry stack rock walls at 111 Scarborough Lane, Christchurch.

Although the scope of work in any other location may have seemed relatively simple, Ice Excavation faced many hurdles to overcome including keeping a single lane right of way operational for residents continual access throughout 90% of the job. This was made possible by installing a temporary bridge/work platform, giving us the ability to excavate under the roadway to the bedrock to anchor the base for the retaining walls while still being able to move machinery out of the way into the only single parking space adjacent from our work area. The bridge/working platform also eliminated the risk of machine roll over into the cut area and adjacent house.

Temporary safety nets and protection were also installed to minimise the risk of loose rocks from excavation/rock breaking tumbling down into the property and/or dwelling. Over head wires and an old water main were also part of the risk profile of the project, however with skilled operators and careful guidance by vigilant trained labourers on the ground these services remained intact.

Ice Excavation received positive feedback from not only the client, engineers and home owner but also from all the surrounding residents who were pleased with the right of way remaining open throughout the project.
