Old Growth our timber engineering heritage

This issue's Old Growth comes from Trada Bulletin Vol 3 No. 8 of November 1970 and since the photo shows thecompleted structure, it would have been designed around the time that Trus-Joist Corporation in USA was born, with thedevelopment of tubular metal webbed trusses. It is nice to see the New Zealand was also at the edge of thesedevelopments.
