Not just outsourcing the procurement of materials and components, but also outsourcing of services that traditionally have been provided in-house. The logic of this trend is that the company will increasingly focus on those activities in the value chain where it has a distinctive advantage and everything else it will outsource. This movement has been particularly evident in logistics where the provision of transport, warehousing and inventory control is increasingly subcontracted to specialists or logistics partners. Also, to manage and control this network of partners and suppliers requires a blend of both central and local involvement. Hence, strategic decisions need to be taken centrally with the monitoring and control of supplier performance and day-to-day liaison with logistics partners being best managed at a local level. 7. Performance Measurement: By taking advantage of supplier capabilities and emphasizing a long-
Bessemer and the open-hearth were perfected (it is uncertain whether the Styrian ironmasters created real steel or whether the decarburization was a mechanical process resulting in a surface- hardened steel, a kind of wrought iron rather than the mass steel that results from the Bessemer process). The first major bridge utilizing true steel was the Eads Bridge (1874), the most graceful of the Mississippi River crossings in the USA, built by the Keystone Bridge Company, which subcontracted fabrication of the steel parts to the Butcher Steel Works and the iron parts to Carnegie-Kloman, both of Pittsburgh. Its ribbed, tubular steel arch spans of 502ft, 520ft, and 502 ft (153m, 159m, and 153m) and double-decked design shattered all engineering precedents for the time: the centre span was by far the longest arch. Mathematical formulae for the design were developed by Charles Pfeiffer. The cantilever method of erection, devised by Colonel Henry Flad
Appendix A: BDS Interview Company being interviewed: BDS Vircon Detailer - Seattle Central Library April 22, 2010 Background info 1. Describe your company's role in the project / your role in the project. My role is, I’m the managing director of the entire company, I run the whole company and we have offices in 6 countries. My office at the time was in Mesa Arizona and we were the steel detailer on the project. So we are subcontracted by the fabricator, Canron Steel. Ok, and which part of the steel… did you work on the curtain wall? We worked on the structural steel. Not the curtain wall, the structural steel? Well, just to clarify. When you look at the picture of it, we did all the steel you can see. We did all the structural steel and the glass frames. Design 2. Did you create your own 3D structural model?
