Temporary Works Toolkit. Part 19: An introduction to the demolition of large stuctures

Many modern office towers are of steel-composite constructione. However, the lightweight nature of steel means a lower modal mass – and vibrations from active sources (e.g. footfall) need be considered carefully during the design stage. This article discusses vibration performance and mitigation based on recent experience in Singapore.

This article explains the theory and background to backpropping and gives advice on the methods recommended to be adopted for backpropping calculations. It looks at the physics involved and how engineers and designers can mitigate damage to concrete slabs during construction.

Site hoarding is a temporary structure erected around the perimeter of construction sites to prevent any unauthorised person gaining access. Hoarding can be erected using a modular system or be a bespoke installation. This article provides an introduction to the design of conventional timber hoardings using plywood sheets.
