Newsletter content
Wind problem in city centre
A reporter shares how they have experienced a spate of wind related incidents where structures which have been designed in accordance with normal practice using current codes have suffered damage.
Roof constructed without structural input
A reporter wants to highlight the problem of builders working off plans provided by an architect or surveyor and assuming that section sizes shown on their drawings are structurally adequate.
Flaws with partial encasements around steel columns
A structural assessment found that steel columns encased in concrete to mid-storey height were heavily corroded directly above the top of the encasements.
Shear failure during demolition
A reporter raises concerns about how a number of buildings being demolished ‘top-down’ have suffered from partial collapse during the process.
Incorrectly designed safety system
A reporter raises concerns about the way in which the structure for a safety system had been modelled using an inappropriate software package.
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.
Failure to check designs produced by software
Concerns were raised about a proprietary design software after a building control officer noticed a regular error appearing while checking calculations provided to them.
