Incidentally, the over 2 mile long suspension bridge photo I posted just above cost just over 1 billion euro, and was completed on time and budget. The state approved design for the replacement Bay bridge destroyed in the Northridge quake cost more than $5 billion (3 billion over budget), and was delayed over a year.
Some things standardized/state sanctioned design works for. Others, not so much...
I spent a long career in Construction and Construction Management. Worked with Owners in hiring many design firms as hiring my own.
30 years back the owner of a design firm complained to me that students graduating from the design fields were coming to him as new hires without the basics in materials, specifications, detailing and the actual skill sets that would fill their first ten years on the boards and CAD screens — they all wanted to be lead designers from day one.
The university faculty had quit teaching the basics, telling the student, you will get that from your first employer, you need to learn the majesty of design.
