"The building of roller coasters seems rather specialized to me. How do agencies set thier standards? Do they contract out to the roller coaster companies themselves??"
Coaster consturction follows the same basic standards as any other structural construction. Each job site has inspectors. They check everything to make sure thing are being done to set specifications from concrete strength, rebar placement to numerous other items. Some inspectors are easy going and let some minor things slide while others want things exactly the way the blueprints call for it.
As for contracts the park will take bids on construction from the excavation, rebar, concrete suplier, structural steel setting, carpentry,and electrical portions. Each company gets a list of what needs to be done, supplies, and the target completion date. From that each company will make their bid. All the jobs I worked on had many contractors working together each specializing in a different trade or area of a trade.
