  • Speakers Info about who's talking

New 7D modelling tools now allow for the integration of multiple workstreams on a common data exchange during design and construction, which enables the real-time calculation of project cost, programme, energy, sustainability, risk and long-term performance.

This session explores how such platforms enables greater transparency in data, contract and payment management – all which are much needed in delivering a circular economy. Speakers will take viewers through the journey of a steel beam to demonstrate how it all works and the benefits in practice.

Ahmed Zghari-Sales

Chairman, Construction Blockchain Smart Contracts Committee; Co-Founder Helium Blockchain Association

As Chair of the Blockchain and Smart Contracts working group, the team are looking to develop open source tools and processes that will enable the construction sector to speed-up the pace of technology adoption aimed at increasing productivity, reducing waste and opening up data to further encourage technology firms outside the sector to enter and help drive change in this complex, adversarial and largely analogue sector. As Co-founder of the Helium Blockchain Association, the team of blockchain experts will be seeking to make public ledgers running smart contracts accessible to small and medium sized businesses across a number of sectors, from construction to energy delivery.
