506 Wind problem in city centre
A reporter is dealing with temporary works for sub-contractors working in and around the centre of a major city. He has experienced a spate of wind related incidents where structures which have been designed in accordance with normal practice using current codes have suffered damage and he feels that there is an issue which needs to be investigated and discussed so that Engineers dealing with structures in the vicinity of tall buildings and groups of tall buildings are fully informed.
529 Risks from off-site manufacture and hybrid construction
A reporter was recently investigating a ‘near miss’ involving concrete construction in which pre-cast and in-situ concrete were used in combination. This type of construction offers efficiencies and, as in this instance, can reduce the number of man-hours worked at height. It is growing in popularity. It does however bring its own risks, and these need to be understood. The works under investigation comprised a circular shaft 20m in diameter and 20m deep, which required an L-shaped shelf or balcony some 5m from the top.
