Hi Lucas,
Yes, the budget is one of the trickier aspects of the EWB Challenge and it is a skill to be able to articulate the value of a design, but it sounds like you’re on track!
In terms of your other questions, I’ll get back to you about the excavation experience of staff. As I mentioned earlier, the maintenance crew are trained in some trades, and will have general handy skills, but I’m not certain about excavation specifically so I will check this and let you know.
For the three potential sites, they currently sit as they appear in the interactives – that is, there are no structures (roofed or otherwise) associated with Dawul Wuru there.
Thanks,
Rachel
