The ret­ro­spec­tive of the en­gi­neer­ing ar­chi­tects Jörg Schlaich and Rudolf Berg­er­mann, “le­icht weit – light struc­tures”, was pub­lished as a hard­back book of the same ti­tle. It also ap­peared as a brochure and was even trans­lated into Chi­nese in 2004. Along with giv­ing an overview of the nu­mer­ous mag­nif­i­cent pro­jects of the Schlaich Berg­er­mann team, it also cov­ers de­tailed con­struc­tions. Lav­ish pages take turns with com­pact text-im­age stretches, lead in by chap­ter in­tro­duc­tions re­sem­bling an in­dex.

This elab­o­rate tril­ogy is tai­lored to re­flect the en­gi­neer­ing feats and the en­gage­ment in the restora­tion of con­struc­tions that are no longer func­tional. The adap­ta­tion of a clas­si­cal type­face and a flex­i­ble lay­out en­ables com­plex ma­te­r­ial to be processed in a clear man­ner. All three vol­umes are kept to­gether in a sturdy slip­case. The con­struc­tion en­gi­neers “Fhecor In­ge­nieros Con­sul­tores”, based in Madrid, Spain, ini­ti­ated this book pro­ject.
