Book review: Control of cracking in reinforced concrete structures

This month's letters scrutinise the President's views on site supervision, raise some interesting questions in the aftermath of the Grenfell Tower fire, discuss the benefits and drawbacks of BIM, as well as commenting on concrete design to the Eurocodes and British Standards, fracking and various other topics.

This is a useful book giving insights into special horizontal loadings on building structures, suitable structural resistance systems and current US design office practice, says John Lyness.

Balazs Trojak challenges BIM refuseniks to dip their toe in the water and explore its benefits, or risk irrelevance in an increasingly digital future.
