A few thoughts having looked at the detail a bit more.If anyone wants to comment on the paucity of the design or insuficient level of information:
The bollards specified in the application are by Safetyflex. The exact model isn't clear, but from the dimensions my guess is that they are the Truckstopper 5 - designed to stop an 18 ton truck travelling at 50mph. Interestingly, the default shroud is smooth stainless steel and a much better match to the rest of Windrush Square.

If this is correct then to me that seems to be an over-specification given the difficulty in getting sufficient run-up to achieve those kinds of speeds for any vehicle, let alone an HGV.
The bollards are massive too. Nearly 4ft tall and over a foot thick. As drawn they are at 1200mm and 1400mm centres - leaving gaps between them of 875mm and 1075mm respectively. To put it another way, around the main entry points to the square they're less than three bollard-widths apart. These things don't just drop into a hole either, they need a foundation trench 1200mm wide and 400mm deep.
Not only is this in contravention of the design and access statement for Windrush Square (which has a minimum 1100mm clear width between all fixed street furniture), it sets them far closer together than the manufacturer's own recommendations - which call for 1200mm gaps. It suggests to me that whoever did the setting out doesn't understand the basic arithmetic.
Then there is the exact placing of each bollard. The details around the CHL and Saltoun Road crossings are especially problematic. Windrush Square is not a level site and has been contoured so that all the main paths are step-free shallow gradients. What happens when - say - an electric wheelchair user finds a huge new bollard in the middle of a path, such as at the corner in front of BCA?
I'll stop now. I haven't even begun on the aesthetic and conceptual implications yet and I'm getting annoyed and have work to do...
