Replace the fallen rose trellis / pergola
In Pittsburgh, the grounds of the estate of Henry Clay Frick, the wealthy industrialist and contemporary of Andrew Carnegie, contain large garden areas adjacent the large manor house and other buildings. In front of a house called the “play house,” so named because it was built for the children to play inside, a rose trellis existed, but collapsed a couple weeks ago. A big wet snowstorm hit Pittsburgh, causing the light structure to cave.
Here are two pictures showing the structure before the collapse.
My sister, who is the controller for the Frick Art and Historical Center, asked me to design a new one, and to provide the carpenter with detail drawings.

Powder coated aluminum or steel?
I wouldn't make it out of wood again. 3" square tube, heat bend the arches, 1-1/2 square tube stringers. You could have a shop weld up the truss/supports and trailer it in. Several coats of red oxide, and then the color they want.
You could call it "gorilla rose trellis..."
I cannot say whether the tapes were read accurately, but member sizes were reported to me as follows.
All posts 2-1/8" square.
All lattice slats 3/4" x 2-1/8" in section.
All curved "beams" 3/4" x 3" in section.
Species reportedly was redwood, and all parts painted white. The structure dated back at least 35 years.
This, plus some details, is what I submitted for review by the site manager and the carpenter who will do the work.
All parts called out as made from clear western red cedar. Posts are 2-1/2" square, larger than the 2-1/8" posts that were there. Curved rafters are a full 1x4.5, and are 4-ply glue-ups.
