Window cleaning schedule up to Jan 2014

Here is the window cleaning schedule for the Barbican to the end of the year and into early 2014.  Ben Jonson Windows will be cleaned on:

• 30th August - 5th September
• 11th - 17th October
• 22nd - 28th November
• 10th - 16th January

I suspect this appeared on notice boards some weeks ago.  I didn't spot it as it was hidden beneath other notices.
