You will be responsible for carrying out a task according to instructions given by the instruction group.
The instruction group may call you in to give you instructions at any time. If they do not contact you, you are to report to them anyway, so you can begin your construction task exactly thirty minutes from the start of the activity. After that time, no further instructions will be available.
You will have ten minutes to complete the task you are given.
Prior to meeting the instruction group, you may wish to spend time considering how your group can be most effective: discuss the different expertise of different members of the group, the way you will work together, the leadership needs of the group, the organisation of the task, etc.
