We built two of these radio telescope tracking antennae
for NASA's MARS project in the early 70s.

The dish is 64 meters (210 ft) in diameter. One was erected in Spain, and
the other one went to Australia.







The American Institute of Steel Construction (AISC) awarded us the
"Most Beautiful Long Span" prize for this bridge, opened for traffic
at Libby, Montana in 1971.




The American Institute of Steel Construction (AISC)
also gave us an award of merit for this short span bridge
over the Cle Elum River, Kittitas County, Washington.
