The following information is intended to allow everyone who uses the David Williams Building, which houses the Faculty of Law and the Squire Law Library, to understand and to place themselves in a position to observe arrangements that are intended to enable the building to be used appropriately during the Covid-19 pandemic. The following arrangements regarding the use of the David Williams Building have been devised in the light of relevant guidance issued by the University and by the UK Government and should be read in conjunction with that guidance. Should Government or University guidance change in a relevant respect, the arrangements for the use of the David Williams Building will be amended accordingly; members of staff and students will be notified by email of any key changes. Please also refer to the University's Stay Safe Cambridge Uni webpages, which set out the approach that is being taken in this area across the collegiate University.

Symptoms and self-isolation

If you have any symptoms of Covid-19, you should follow official advice regarding self-isolation and should under no circumstances enter the building. Members of staff who develop symptoms while in the building should notify their manager and then leave work immediately, thereafter following official guidance regarding self-isolation and testing. Students who develop symptoms while in the building should leave the building immediately, notify the Faculty as soon as possible (by emailing that they developed symptoms while in the building, and thereafter following official guidance regarding self-isolation and testing and any relevant guidance issued by their College. Anyone who, while in the building, receives a notification requiring them to begin a period of self-isolation should immediately leave the building. Students who receive such notifications during a class should immediately notify their lecturer so that the lecturer can implement the protocol that the Faculty has adopted for such circumstances.

Scanning QR Codes

The University has committed to keeping a register of those who attend in-person classes. It has been agreed that the easiest and most efficient way to do this is via the NHS ‘Test and Trace’ app. As such it is now mandatory for all staff and students attending in-person teaching sessions, in the Faculty, to scan one of the many available NHS QR codes provided.

Whilst you only need scan once per visit, NHS QR codes can be found at multiple locations around the building including: on the front entrance noticeboard; at reception; outside lecture theatres; and at the Squire Law Library entrance.

For information on using the NHS Test and Trace app/QR Codes, please see the NHS website.

Social distancing

All teaching rooms, library areas and offices have been configured to facilitate 2m social distancing. Markings and signage in each teaching room, library area and office clearly indicate seats and desks that can and cannot be used in accordance with social distancing. Building users should ensure that they comply with such markings and signage and should also observe social distancing while moving around the building. An office should not be entered without first seeking the permission of the occupier.


Excellent hand hygiene remains a key infection control measure. Hand sanitiser is available at the entrance to and in multiple locations around the building. Everyone should use hand sanitiser on entering the building and as appropriate while in the building.


Cleaning will take place in the building throughout the day. Cleaners will target 'high touch' surfaces and shared areas within the building (e.g. lift buttons, door handles, water coolers, kitchens, taps, toilets). Teaching rooms will be cleaned between teaching sessions.

Face coverings

In most circumstances, it is necessary to wear a face covering while in the David Williams Building unless you are exempt from the requirement to do so. (a list of exemptions can be found on the University website). This means, among other things, that face coverings must be worn on entering and while moving around the building, by students and lecturers during classes, and while using the library. Members of staff do not need to wear face coverings when working alone in their office or when working in a shared space in which social distancing can be maintained at all times. For the purpose of the Faculty’s face coverings policy, 'face covering' normally means a face mask. However, teaching staff may, during in-person teaching sessions, wear a clear full-face shield if they prefer.

One-way and 'keep left' systems

One-way and 'keep left' systems are in place in some parts of the building, including on staircases, in some corridors and in teaching rooms. Where this is the case it is clearly indicated by signage. All building users are expected to observe one-way and 'keep left' systems where they are indicated.

Before and after teaching sessions

Students should not congregate in corridors outside teaching rooms before or after teaching sessions and should avoid arriving more than a few minutes before the scheduled start time for their class. On arrival at their teaching room, students should generally find the room empty (because back-to-back classes in teaching rooms are not being scheduled to allow cleaning between sessions) and should enter the room rather than waiting outside. If, however, students find that a teaching room is occupied (e.g. because cleaning is still in progress) they should return to (following any one-way system) and wait in the lower-ground floor or the ground-floor atrium provided that social distancing can be maintained there. If social distancing cannot be maintained in the atrium, students should wait outside the building and should return to their classroom only at the scheduled start time for the relevant class. At the end of classes, teaching rooms should be vacated promptly, in order to enable cleaning to take place, and students should not congregate in corridors outside teaching rooms at the end of classes.
