Order of rsj fitting

[Galgt4]

Hi All, 

 

trying to figure out the best order to get these steels in shown on image in blue.

internal existing and new beam b's have block walls on top upto roof supports then the big supporting beam across the back of the house. This weighs around 650kg and will be sat on engineering brick pillars either side. the existing beams will connect to the supporting beam with cleat connections.

 

would you fit the large beam first and then the two internals? also steels will be going up in between joist so top of steel to top of joist height.

Long beam needs to go in first, as the two others appear to then hang off it. You wouldn't want to be hindered by the other smaller beams when getting the big ones in position, so that's what I'd do.
