You can always say you are on time and on budget as long as extensions come your way. My point was not saying that this project was not on time or on budget, it was mainly to illustrate that the 3 days of work that locals saw was based on 5 years of research and preparation. I recently read 'Built: The Hidden Stories Behind our Structures' by Roma Agrawal and it would be fairly rudimentary for a structural engineer, but for the average passerby it was a very interesting read on some of the structures that we use every day! (and how some of them are miserable failures haha)
