Horsley Water Treatment Works Upgrade

Hello everyone. In today's update, I want to concentrate on the works we are carrying out next to one of the water main in the south east quadrant of the Horsley site. We are carrying out piling operations before we start on the connection works.

We have designed and constructed a piling platform. This is to take the weight of the piling plant and equipment when we start constructing the piles. This platform will also take the pressures the piling plant and equipment will impose on the ground. The piling platform is constructed from well compacted granular material laid on top of a geogrid support. 

To construct the concrete pile, we will be cutting through clay, augering through the sandstone strata and drilling through boulders. The equipment we will be using is powered by compressed air. The plant to generate this pneumatic power has been set up on site next to the works area.

We carried out pre-start ground investigation surveys to determine the type of ground present at the piling location. Our team is prepared to auger and drill trhough the different types of ground that we expect to encounter. This photo shows the augers that are used to drill through cohesive material.

Our site teams are monitoring noise levels and vibration levels at the works area and at the site boundaries. There are no concerns regarding noise or vibration. Our site operations are progressing well. We have constructed several reinforced concrete piles and we expect to finish our piling operations in line with our programme.
