Routine design When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art. The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.

Don’t Be an Ostrich An Essay by Chuánqí Sun medium.com You just handed off a major redesign. Three months of research, twenty-seven major revisions, and hundreds cups of coffee have all culminated in this pinnacle of glory. It’s finally done! Except it’s not. It’s not, even after you have answered every single question the developers have about your red-line. It’s not, even after you have addressed all the technical constraints developers encountered during the implementation. It’s not, even after you meticulously documented all the patterns and styles into a library for reference and reuse. It’s not, because neither you nor the developers have talked to a real user. At the bottom of your heart, you are secretly wishing: My design looks great on paper, so let’s keep it on paper. You are an ostrich. Post-occupancy evaluation
Post-occupancy evaluation Post-occupancy evaluation (POE) is a practice in the building industry where an architect would visit the building after its occupancy and interview its residents. It sounds like a great opportunity for collecting feedback and learning from mistakes, but it’s rarely practiced. Why? Many awe-inspiring, prize-winning architectures are half building, half sculpture. Often made of specially molded concrete and steel, they are extremely expensive to alter, let alone any alteration would also attack the architect’s prestige and pride. So whatever usability issues the POE identifies will remain as issues, unless the architect wants to accept the public criticism and shame that comes with the remodeling. In fear of criticism, an architect would turn down the opportunity for POE, and continue to design the same roof that would leak water in future projects. In fear of criticism, a developer would use customer service representatives as a shield against user complaints, while focusing on the “technical” aspect of things. In fear of criticism, a designer would close the contract as soon as the client accepts the design, even though none of the real users are represented by the client. architectureux
