I think that the "dogs heads" will have bearings on them which the arch is fitted to. This is good enough to hold the weight of the arch. Trouble is, if the arch was on its own, it would just turn upside down due to being on the bearings. Therefore, the temporary supports keep the arch in the required position until the roof trusses go on which will keep the arch in a permenant position when the temp supports are removed.
It's one of those jobs where everything supports evrything else and when all in position , is a damn strong erection (ooooer mrs !!!!)
I hope
