Roof Trusses going up and minimal engineering

Got sent these photos during the day from her indoors.

The first two were in the morning and the last was by 3:30.  Not bad for a days work.

I also phoned the builders office to see if I could get the engineers design for the frame.  Here is an extract of the extent of what they have:

Note that the above "engineering" states "conventional timber flooring to AS1684.  I was expecting a little more.  It would be like a bridge engineer showing on a drawing Point A and Point B with a line between stating "bridge to AS5100"  It would make the engineers job a lot easier, however I wouldn't want to be the people constructing the bridge.
