the amount of polycarb needed to cover our roof, is the same amount required to surround it, therefore doubling the quantity. This provides several issues; the structures won't take double the weight, a 12m span needs alot of support (more weight), all of this has to be transported (another truck, driver and fuel), all this has to be setup (get-ins are already a rush to get up in the amount of time, therefore would require more crew or time), all of this has to be paid for (probably looking at £10k on the investment and plus the additional costs at every event). All for what result, a couple of robots that won't be competitive?
