Update by Shafqat Akbar
Hello everyone. The site teams are moving into the next phase of the project. In this update, I want to tell you about the works that our sites have started.
We are preparing to start the "shaft sinking" operation shortly. This is a major element of the work that we are carrying out during the pumping station refurbishment and upgrade works. These works will take about three months to complete.
The new shaft is approximately 5m in diameter and 10m deep.The shaft will consist of a cofferdam, collar and rings. There will be a 2.3m base at the bottom of the new shaft. The shaft will be constructed using a "push and dig" method.
We will not be using a dewatering system on site to manage the water table at the shaft sinking location. The excavated material will be excavated below the water table and allowed to dry out on site before it is taken off-site.
Our management team are ensuring all the covid-19 controls are still in place. We are supporting the NHS campaign of "Hands Face Space" on site. We have a number of hand sanitising stations and there is a policy of wearing face masks in the office and site where a social distance of 2m cannot be maintained.
