Summerhall must be contacted before any Hacklab activity is carried out on the roof (not including the plant room). This is to avoid causing alarm to security personnel.

Weekdays before 18:00: email the list of contacts below, before going onto the roof.

At other times: email the list of contacts below, and also speak to the reception desk or contact the duty manager or security by radio.

dm@summerhall.co.uk, info@edinburghhacklab.com, lizzie@summerhall.co.uk, marcus@summerhall.co.uk, maintenance@summerhall.co.uk mailto

This is the process agreed between Al and Antonia on 28th May 2018.

The following is a known good email body

Hi all,

As per the agreed procedure, a team of 2-3 Hacklab members will be 
accessing the B-Block roof to perform some maintainence this evening 
from around 18:00.

Since this will be after 18:00, we will inform reception just before we 
go up.

Other Rules:

• Don't go on the roof in bad weather.
• Don't work alone.
• Stay away from the bees, especially during warm daylight hours.
