What is the Role of Piling Rigs on an Overturning Construction Site?

Modern piling rigs, characterized as having a high center of gravity, usually weigh around 200 tonnes. 

One part of the rig referred to as “leader, can reach up to 30 meters high, thus by virtue of its high static weight together with all the physical forces exerted while the rig is moving or is actively working signify that the ground conditions underneath them are a critical safety issue. 

Every year, a handful of these rigs in the country topple bringing about serious property damage and alongside that also cause a business interruption. Scenarios like that are likely to occur because of inadequately maintained or prepared site surfaces. 

A plant’s stability will highly depend upon having in place a well inspected, prepared, and maintained site surface. Coordination between principal site contractors and piling firms is critical. Details of the plant need to be utilized and there should be the provision of bearing pressures. As for the site surfaces, preparing them correctly in advance is important before commencing any kind of work.  

Working platform:

Temporary geotechnical structures provide a stable and reliable working surface for mobile cranes, piling rig, and other similar heavy construction equipment. The working platform will serve as the piling rig foundation and there is nothing unusual about it if it weighs up to 200 tonnes.  

Working Platform Certificate: 

This certificate is the affirmation that a working platform underwent proper design and was constructed in compliance with design. Besides, adequate maintenance will be ensured to keep the platform integrity intact. This also necessitates the main contractor signature and should be relayed to the designated piling contractor before any kind of foundation or piling work commences. 

The certificate will also emphasize specific responsibilities, improving awareness on safety measures, and stressing on the importance of keeping and maintaining the platform in very good condition all the time.  

Working Platform

piling rig

This name is used when referring to a designated site area where the piling rig is supposed to travel during its delivery to the site, as well as when there are piling operations, and during its removal. The maintenance, design, installation, and repair works are all under the main contractor’s care and responsibility. The ground itself will need to be checked upon, and as far as its stability is concerned it needs to get confirmed, too. 

Working to affirm ground stability will sometimes also cover integrity and load testing, looking into or probing for any kind of irregularity as well as working on important remedial works. The ground must be free-draining, this will help in keeping water and slurry from build-up. 

In some cases, there is a need to install beneath the platform filter or separation membranes. By this measure, the weakening of the ground strength could be averted. 

Working Platform Certificates are now seen as an effective way to ensure the following: 

  • Adherence to the use of correct procedures
  • The ground working on is providing enough structural support to the piling rig
  • The likelihood of the occurrence of irregularities following toppling and local subsidence. 

What a visual inspection does will only cover for the ground surface. Checking out the quality of the fill, underlying material as well as its depth and construction, and lastly the application of the required material.
