New guidance on the impact of tall buildings on wind loading has been issued, after concerns were raised about the design of some temporary works.
The concern is twofold: firstly it’s that some urban temporary works such as scaffolding or huts on building sites may be constructed without adequate wind loading taken into consideration – particularly the impact of nearby tall buildings on wind speed and direction. The other is that the wind loading may change during construction as new buildings are put up, and this has to be taken into consideration.
Structural-Safety says it has received reports that temporary works have suffered local wind damage, and it is suspected that is, in part, because wind loads have not been determined correctly. It has therefore issued an alert on wind loading and the impact of adjacent tall buildings.
Structural-Safety director Alastair Soane said: “We are interested in whether or not the climate is becoming increasingly windy and therefore any feedback is welcome.”
