we went down to Populous’ ofﬁces in
Kansas City,where we were able to look

what the geometry of that leaning
curved wall was,” says Niepokoj. “… I
think where we enhanced it the most
was really just proving to the team that

To set in the lites, the glaziers inserted

They then pushed the last corner into
its twisted, cold-formed ﬁnal position.

Reynolds says every lite of glass, cur-
tainwall and panel are supported by
structures designed by his company,
which is also the engineer of record for
the enclosure. He says the joint work

was among the most cohesive he’s seen.
“It was the best collaborative effort I
think we’ve had with an architect,”says
Reynolds.“On this project,we can truly
say we were on the same team.”
And the teamwork between the glazier
and architect was only the beginning.
