Sorry all, haven't updated this for some time, there wasn't a lot of progress initially but now things are fully mobilised on site.
Anyone coming to the November 11th ceremonies in Whitehall can head across to the far end of Green Park (quite a walk though) to see progress. Sorry, I gave an inaccurate location earlier of the site in the park (now corrected), it is actually here :
Google Maps
at the very west end of Piccadilly, facing the Hard Rock Cafe across the road, alongside where the westbound Hyde Park Corner underpass starts to go down. Nearest Underground is Hyde Park Corner.
Google Maps have bizarrely plotted the InterContinental Hotel, London, right on the location in the park where the memorial is going !
The selected contractor is Gilbert Ash, from Belfast, now fully mobilised and with a large crane installed to handle the various masonry blocks. Stonemasons are S McConnell & Sons, who also did the stonework on the Diana Memorial in Kensington Palace Gardens.
