Most recently, when Márton's curious puppy, Micike, escaped, the firefighters had to rescue him from a construction pit. How lucky that nothing happened! And what luck that all this happened during a large construction site!
The Mártons don't even wake up from all the excitement, a construction manager in a yellow hat walks up to them. Uncle Bandi is a bit afraid of dogs, but fortunately he is happy to show the little boy around the construction site. Cranes, pile drivers, jackhammers are buzzing everywhere, but there, in the corner, there are even archaeologists working!
How long does it take for concrete to harden? How many meters tall is a crane? How is the stairwell or elevator shaft built? And what happens to the 2,000-year-old pots found? The book provides thorough and humorous answers to these and many other questions worthy of the author couple.

(Not only) For fathers and sons!
