Dear All
You will be aware of the recent media reports of the planned demonstrations/protests in respect of the above ["G20 Meltdown"]. Anarchists and anti-capitalists intend to hold a 24 hr ‘Reclaim the Streets’ style event in the City. Attendance can be expected to be between 1,000-2,000, although this cannot be confirmed
The City is likely to be subject to significant disruption for the duration of the summit. Heightened security measures, traffic congestion and road closures should be expected. Four parades starting at 11am on Wednesday 01 April 09 from four main railway stations around the edge of the City of London – Moorgate, Liverpool St, London Bridge and Cannon St – which will eventually converge together at the Bank of England at around noon.
Whilst we do not believe our City office is at risk, it is essential that suitable precautions are taken. Having consulted with our own Building Manager, the Metropolitan Police and banking institutions in and around the City of London, the following precautions have been agreed:-
All client meetings here or off-site to be cancelled unless in exceptional circumstances.
All staff to dress down to avoid the possibility of confrontation whilst on the street or public transport.
Non essential staff or those who can work from home, with line management agreement, to do so.
Staff from other Lark offices should avoid travel to the London office.
In addition, security at Ibex House will be increased. A partial lockdown of the building on the 1 April will include locking of both single leaf entrance doors, physical locking of interconnecting doors between the Health Club and Ground floor corridor.
It would be appreciated if the following requests are adhered to:-
Keep removals/deliveries to a minimum, no large deliveries (more than 1 trolley load) if possible.
Use the Delivery Proformas.
Keep Visitors/Couriers to a minimum.
Use the Visitor Proforma. Access control proximity cards/fobs to be used by all Occupiers all of the time, disabled gate will only be used for its intended use or deliveries for Tenants who cannot access from the rear of the building.
Database reports have recently been sent to you all for updating, so all Occupiers should now be in possession of an access card/fob.
Staff movement into and out of the building should be kept to a minimum over the period.
Cleaning and other Contractors to display their Building I.D. at all times.
It would be prudent to leave cars and bicycles at home for the day.
Encourage all staff to maintain vigilance, do not allow tailgating to occur, do not be embarrassed to challenge anyone on your floor who may not be familiar to you..
Report anything suspicious, immediately to Security.
Should the above cause any work related problems or concern, please contact your Manager/Divisional Director.
