The bar joists span between the main I-beams which are supported by the columns. As long as you are being faithful to the prototype, you may need to build some.
I did just browse Google. There is also a more simple version with I beams only instead of the complicated construction on the photo (I know an I beam is much heavier and therefor often replaced by a more complex but lighter construction). There are two more aspects
- The prototype has much less columns as my first model has
- I need some columns to support my model roof
