Hi Mark,

Yes to your question...

Lots of CAD experimenting and hand drawing of this and bridges, as well as modeling.

I've built a few small transient structures but not quite as big as yours.

If jointed...The layout accuracy is hypercritical...!!! Top of the game stuff to get the joinery to work in a structural capacity...Many ways to do it...

Lashing much easier (of course.)

No matter the method...some form of "band beam" with tension adjustable joinery or "perimeter banding" (cable, rope, webbing, forged strapping etc) is an absolute must if the structure is meant to last any length of service time...Also not that additional tensioning joinery and/or banding in the upper roof structure is highly recommended for this type of roofing system...Many are already showing signs of..."creeping sag!!!"

As always, if not well seasoned to this craft...do seek PE advise and guidance from an engineer with a timber framing background if at all possible...

Good Luck,
