Parents need to know that this educational documentary-style show focuses on large-scale construction projects (bridges, roller coasters, highways, etc.). There's nothing eyebrow-raising here except perhaps for a little bit of tension during moments of crisis when something doesn't work like it should. The featured experts are well behaved and share their extensive knowledge freely. Younger kids may find some of the complexities involved in these projects boring.
Positive messages:Promotes learning about our environment. Some projects are environmentally friendly. The show focuses on projects from around the world -- not just the United States. Workers are mostly male, and -- depending on the episode -- sometimes mostly Caucasian.
