Video | Watch J Coffey deploy Tarmac’s digital concrete strength monitoring

While concrete maturity sensors are well-known, Tarmac's CEVO Digital brings AI into the equation, enabling it to alter mixes in response to environmental conditions while meeting J Coffey’s project requirements.

Tarmac commercial manager Jospeh Kirwin explains: “What was different about this use of this digitalisation of concrete was the introduction of the mix AI software. We provide precalibrated mix designs. This allows us to, early on, identify, optimise and engineer out concrete overstrength, and this delivers the carbon savings that are required on site.

“The CEVO Digital mix AI software enables us, in real-time, to make data-driven decisions on the performance of the mix versus the ambient temperature at the time. We speak to J Coffey daily, and we look at the data that’s being produced by the software. This enables us to look at the sweeter mixes that have been provided, [and] choose the most suitable mix that has the lowest carbon value possible that won't impact on programme strength or quality for this specific project.”

Chris Wellgreen, sustainability, systems and carbon manager at Coffey, said: “We’re really bringing technology to the forefront of how we engage with our clients, making sure that we are able to give them real-time data on what’s happening, as opposed to a retrospective look at what we’ve done. We rely on [our supply chain] to bring technology forward for us to present to our clients and engage with them on site. CEVO, for example, has been a great piece of technology brought to us from Tarmac."
