The Challenge

The unique composite steel/concrete design of the VCs generates both the necessary structural requirements to fully support the internal PT floor slabs and also provides the necessary fire resistance to minimise the requirement for any intumescent coating to the steel.

A strict off-site inspection regime was agreed between the parties to ensure BoA could guarantee both the structural strength and architectural consistency in the colour of the black pigmented coloured concrete, to ensure none of the 3.5 tonne columns was rejected by the client.

The BoA team researched a number of concrete batching plant companies and options. The final decision was to purchase an FS500 Mobile Concrete Batching Plant from Fibo Intercon.

The decision was made in favour of Fibo Intercon because we listened and adjusted the batching plant adding fine-tuning controls so that each batch of concrete would be consistent in batching, to guarantee both the strength and colour of the concrete mix.

The Solution

The fine-tuning involved adding a frequency controller to the cement auger motor. The speed of the cement auger is reduced by a frequency converter and is controlled by the batching plant software during dosing.

The fine-tuning of the cement batching meant that the colour of each batch was the same. You can see the results in the images.

A router was also added to the FS500 allowing our engineers in Denmark to support the production team in setting up the plant and adjusting the software program to tweak the production process.

The FS500 was connected to a 60-ton cement silo that Fibo Intercon helped Barretts to hire within the UK.
