Mr Johnstone a chartered engineer with a post-graduate degree in structural research. He has 25 years of experience working as a consultant, providing structural design services and managing large-scale construction and demolition projects in the industrial, petrochemical and nuclear sectors.
“From the outset of my career demolition has been an area of particular interest, and my motivation has always been to identify the safest way possible to demolish any structure; be it by machine, dismantling, controlled collapse or the controlled use of explosives” he said.
Keltbray Group managing director John Price said: “We’re delighted Bob is joining us, as his understanding of how a building was originally designed, and how the structure may have been altered and deteriorated over the years, is essential when considering demolition options. This is especially the case when using controlled explosives, where ensuring workforce safety during the building preparatory works before blowdown, and achieving the designed mode of collapse during blowdown, are both crucially important to the success of the project.”
Mr Johnstone is based in Keltbray’s Leeds office.
