So, let us compare and contrast the two projects from an engineering perspective. Technology A very large wooden ship . Finally, there is no mention of watertight bulkheads, lifeboats, or survival suits. So the technology is only marginally up to the task. A large tower made of fired bricks .
Bricks are very strong in compression.
Bricks were also a proven technology. So there seem to be no technology problems. Clearly, the job has gotta get done before the rain starts. Gen. 7.4 says 7 days, but I think that is the time to load all of the animals onto the boat. No mention of any schedule constraints.
