CDM 2015 Designer Duties – Considering temporary works in permanent works design

CDM 2015 Regulation 9 requires Designers to eliminate, reduce or control the risks through design.  Where it is not possible to eliminate risks, they should provide information on the significant residual risks that could not be designed out.  As part

Understanding CDM 2015 Designer Duties

I gave a presentation at the Institution of Structural Engineers Small Practitioners Conference on 26 June 2018.  That presentation focused on understanding the CDM 2015 Designer Duties. This post contains the video of my presentation.  The slides can also be downloaded.

Deterioration and defects – what are the risks to the safety and service life of concrete structures?

Concrete structures can be affected by a range of defects and deterioration.  These can impact on both the safety and service life of structures. The most common forms of defects and deterioration that may occur in concrete structures, how they

Impact of corrosion on the safety and strength of concrete structures – Summary of the mechanisms

Reinforced concrete structures degrade with time and exposure to the environment, particularly if that environment contains salts.  That degradation can lead reinforcement to corrode, and this can affect the safety and load-carrying capacity of concrete structures. The data from existing research were reviewed

Impact of deterioration on the safety of concrete structures – what can designers do to minimise risk?

This article discusses the impact of deterioration on the safety of concrete structures.  This is illustrated by examples where deterioration has led concrete structures to collapse.  The article suggests steps that designers can take to minimise the risks of deterioration to safety and discharge
