Constantly improving techniques used on site: vertical draining

Sites should always seek to constantly learn and improve safety and environmental methods used on site.

Below is an example of how a site adopted an alternative method, to minimise disruption to the local community and reduce carbon emissions:

  • Wick (vertical) draining was carried out and then the contractor surcharged part of the site, resulting in the ground being stabilised and providing a suitable sub-base and formation to enable the works to proceed;
  • This operation was undertaken instead of the original design to carry out vibro compaction;
  • This proved to be a more cost effective operation, which reduced the number of deliveries of stone upfill (which is required in vibro compaction);
  • The reduction of deliveries to site, also resulted in a smaller project carbon footprint and minimised disruption to neighbours;
  • This method further reduced the consumption of natural materials.

In this case, the contractor influenced the design of this newly implemented technique.
