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.

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.

Well-designed and well-executed temporary works solutions can lead to big cost savings, while providing a safe and efficient environment for the permanent works to be built. This is particularly the case with below-ground temporary works, where there are a great many challenges to be faced by a temporary works designer.
