This is an unusual but very worthwhile book. There are architectural books that focus on a single "work" or building, but the only similar books in structural engineering are ones that focus on distant rather than recent history (Brooklyn or London Bridge, for example), and that pretty much ignore the technicalities that are inevitably central to bridge construction.
This book focusses entirely on the Alamillo Bridge in Seville, a highly unusual (and highly uneconomic) cable-stayed bridge where the pylon is inclined away from the main span, and not restrained by any back-stays. Unlike a conventional cable-stayed bridge, it therefore relies entirely on bending of the pylon to resist live loads (dead loads are balanced by the pylon's self-weight) and it must be constructed piecemeal, with the pylon and deck advancing simultaneously, or with massive temporary support. This leads to the serious lack of economy.
The designer, Santiago Calatrava, has rarely been bothered by the conventional wisdom of bridge engineers, which holds that economy leads to elegance which defines beauty. Instead, his bridges owe more to sculpture and therefore have been prominent in a period where the iconic role of bridges has been prized ahead of their pure functionality.
Pollalis' book is fairly dry and factual. He takes the design development, architectural, engineering design and construction planning issues in turn, documenting in detail the process by which this unique bridge became reality. As an engineer, I found the many pages devoted to the structural analysis to be particularly interesting, as it's highly unusual to find such a detailed case study. However, I felt the book was considerably lacking on the social process of design, the politics and personalities. Also, a wider perspective on the architecture would have been welcome, as there is much to debate in the way that bridges like this highlight differences between architectural and engineering philosophies.
The book is well-illustrated, both with photos and engineering diagrams, but also several excellent line drawings made during the construction period.
As a case study, it's an excellent book, so despite the missed opportunities, still very much a favourite.
