  You know, I've always thought National Geographic videos to be the best inspiration for Engineers. Such creativity they showcase, particularly in building Megastructures such as the Burj Kalifa, Palm Islands of Dubai, Burg Al-Arab, and many more. I infact have a collection of such videos with me which are awesome and incomparable with any other source of information. The detailing include geographical location, wind flow direction handling, and many more. You should check it out @#-Link-Snipped-#

  @#-Link-Snipped-# - Design of suspension bridges is the State-Of-Art. Its surprising, whether they really required 30 years to design 3km suspension bridge. There are many advanced softwares and appliation which can give the results in a hour.
  Usually a design of structure will be done under one roof. Detailing is the second process which takes more time to produce the bom & drawings etc. Detailing was splitted into many segments depending on the construction and distributed to several companies.
  For example, Our company worked for WTC1 in 2008, we get an order for steel connection design of 5 floors instead of 100+ floors. likewise they divided the requirement to finish the work quickly.
  Coming to the design of Bridges. Design concepts varies depending on the type of bridges.
  List Of Bridge Types.
  Lets take suspension bridges. Here i list out some rough design procedures.
  

  1. Making of design concept.
  2. Checking the material availablity.
  3. Cost estimation.
  4. Surveying.
  5. Soil testing.
  6. Load assumptions including wind, seismic, ice, Max water level and speed of flow more than past 50 years.
  7. Design of foundation.
  8. Design of primary & secondary members.
  9. Complete Analysis using any design applications.
  10. Design of Pre & Post tendons.
  11. Steel connection design.
  12. Detailing - to produce drawings & BOM
  13. Start execution.
