Arup’s ventilation system optimisation work on the Eurasia Tunnel in Istanbul was awarded the ‘Innovation in Maintenance and Renewal Award’ at New Civil Engineer’s Tunnelling Festival Awards 2018.
The awards celebrate global expertise and project excellence in tunnelling and the judges praised Arup’s Eurasia Tunnel ventilation team for “leveraging available data to significantly reduce operating costs and improve air quality for road users.”
The optimised ventilation operation schedule put in place provides energy savings of up to 80% compared to the original schedule and guarantees the system under any traffic conditions. In order to enable this, the project team used available data to develop an improved ventilation monitoring system for the road tunnel, based on an enhanced understanding of the true in-tunnel conditions.
The judges commented that the team “demonstrated an innovative approach to driving better performance from existing physical infrastructure and the financial and customer benefits were significant”.
