Architect Director, One-world design:
from the poll results I would hazard a guess that B is the UK entry!
As a river crossing the final decision on permission here is made by the mayor of London. If the review does send the project back to the planning authority then this would mean that the existing decision by the mayor would no longer stand. This in turn would mean that even if Westminster passed a second planning application a further decision by a potentially different mayor would then be required. many of the mayoral candidates would not pass it and some have also stated that they would overturn the existing decision. The main issue with the tideway tunnel 'clash' is simply an increase in river traffic which will be carrying spoil - this is inconvenient but not a show stopper. Elsewhere the complications of political moves is influencing the decision makers. For instance I suspect that those who advocate the bridge are hoping that Boris either fails to become an MP or the conservatives win a good majority, ensuring Cameron remains PM. If Boris becomes an MP in May, and Cameron fails to get a majority, there is the potential of Boris becoming the leader of the conservatives and even PM. A new mayor will be elected this year, before the garden bridge starts on site, and they may overturn the existing decision - there is a real possibility that it will never happen.... Perhaps the rush to start construction is more to do with politics than any technical coordination with the Thames Tideway Tunnel?
The solution is to make the building regulations more stringent, i.e. the equivalent of Code 5, moving to Code 6 by say 2020.
This is a real step backwards. Councils such as Woking require Code 5 for new developments, and rightly so. Statutory regulation compliance is the only tool we have as architects that cannot be value engineered out by developers. If Building Regs are only pushing for the equivalent of Code 4 then the volume developments will be designed to meet just that - hugely disappointing.
Comment on: Shortlist revealed in Nine Elms bridge contest
very nice, all but 1 are similar in design, i.e. suspension bridges - the exception being AL's which is a tied arch. The Thames is a designated helicopter route, I hope all of those vertical suspenders and suspension cables are well below the minimum flying height - this area of Battersea has an obvious and recent history in that regard
