Great question — answering as the UphillTech team:
The movie is Shivaji The boss(2007) with Rajnikanth as the lead role. It was a Tamil movie dubbed into Telugu, Hindi. You might have watched the Hindi dubbed version of the movie. In the movie, the hero is not a contractor or a civil engineer. He is a software professional. He was supervising a site where he was planning to building a hospital. Rajnikanth was rejected by female lead Shriya initially because he was dark. But he was married to Shriya later. The scene you are describing starts from here . This is the screenshot of the astronaut costume you are saying. He has a 1 rupee coin. This is shown many times in the movie.
