Project Description

The Think Logistics Plant Movement Team have just completed the first phase of a contract for VVB Engineering at Heathrow Airport. The project was the update of the electrical plantrooms around the CTA Tunnel that runs underneath the runway. This was a challenge that the team undertook with the usual professionalism associated with the Think brand. The survey team did a fantastic job and the standard of the preparation was second to none.

The first phase included the lowering of two transformers into the basement level of the North West Plantroom. Both weighed over 5 tonnes and very little room for error. The team then had to manoeuvre the transformers to the final location within the plantroom. This combined with 44 distribution panels made this a very complex lift but the team finished a day earlier than scheduled.

The Stub Tunnel was just as complex and included 64 distribution panels, a number of which were too large for the opening. A big thanks to the Operations Director, Steve Peggs for coming up with a solution for VVB Engineering. The method included two sets of A frames to lower the units and upright when in place. Again, two transformers both weighing nearly 5 tonnes were carefully positioned within the Stub Tunnel to the great delight of the client.

Currently, the survey team have been looking at a problem for VVB Engineering that includes a tandem lift of 24 x jet fans within the CTA Tunnel itself. The Team have given VVB a solution to a very difficult problem. The Think Team always relish a challenge and as usual we always rise to this.
