2x4s, shower base, flooring

One doesn’t usually get too excited about 2x4s, but these are actually 2 by 4, or close to it.  Plus, they’re fir, not just SPF.  What do I need these heavy monstrosities for?  I need to replace four tie beams (bottom chords) tying my rafters together.  Some crackpot notched one badly, two more are split and compromised, and one more has been drilled through it so many times that there’s no way it is actually holding structurally anymore. 

 

Thank you, Windsor Plywood, or bringing these in!

The shower base is now mounted in place and the drain connected and sealed (silicone – I hate plumber’s putty). 

Laying the flooring for the landing and kitchen has begun. 

 

HFT is holding the floor down with his shoes for me.
