Dr John Orr
MEng PhD
Profile
Dr John Orr is a lecturer in the Department of Architecture and Civil Engineering at the University of Bath. His teaching and research are related to sustainable construction, with emphasis placed on concrete, and structural optimisation.
John graduated with a first class MEng (Hons) degree in Civil Engineering from the University of Bath in 2009, winning three University Awards.
He subsequently stayed in the Department of Architecture and Civil Engineering to complete a PhD in fabric formwork, Flexible Formwork for Concrete Structures, graduating in 2012.
Throughout his PhD John worked in industry with Atkins (ATK:LN), who sponsored his research through an EPSRC Collaborative Award in Science and Engineering.
John joined the Department as a lecturer in 2013.
Research
John has a strong research interest in all aspects of fabric formwork, including its potential to significantly reduce concrete consumption through optimised design processes, and its inherent architectural appeal. His work takes an holistic approach to the unique optimisation, design and construction requirements of these innovative concrete structures.
Further interests include new techniques for the computational modelling of concrete, and the dynamics of lightweight footbridges.
John has been lead author on two award-winning journal papers, both received from the Institution of Structural Engineers.
