and Restoration of Structures of Architectural Heritage (ISCARSAH) founded by ICOMOS in 1996 as a forum and network for engineers involved in the restoration and care of building heritage. The first meeting of the ISCARSAH took place at the Engineering University in Rome in March of 1997 and the committee has met twice a year since then in venues all over the world.

Members of the ISCARSAH are composed of internationally renowned engineers, scientists, architects, specialists, and educators with representation from Europe, Asia, Australia, North and South America.

Dear David/Stephen/Patrick,

I sent the following to officials in Bruuge last month. The US has few examples of Vierendeel trusses, aside from three bridges in Glendale, CA, a suburb of LA, though the Golden Gate and Triborough bridge towers are impressive (renamed JohnF. Kennedy Bridge in 2008). Robert Moses employed the services of famed bridge designer Othmar Ammann. At that time, Ammann had held the position of chief engineer at the Port of New York Authority for seven years. The towers reflected newer design and construction conventions than those originally proposed by Arthur I. Perry. Perry’s original plans for the Triborough towers recalled the dual-arched Gothic design of the Brooklyn Bridge.

Simple geometry and uncluttered lines characterized Ammann's new design. The towers, as with the ornamental light posts on the bridge, reflect the Art Deco skyscraper aesthetics of the era. NY City’s write-up does not reference Vierendeel as the influence for the towers, but Ammann certainly would have known about the structural form.

Though Joseph Strauss is attributed as the engineer-of-record of
