A construction manager is a person who helps build big buildings, like schools or hospitals. They work with lots of different people to make sure everything is done right and on time.
Just like a teacher needs to plan out their lessons before school starts, a construction manager needs to plan out all the things that need to get done before they start building. This includes figuring out how much money they have to spend, what materials they need to buy, and who they need to hire to help them.
Once they have a plan, the construction manager starts working with different people to put everything together. They might talk to architects who draw out plans and blueprints for the building, and they might work with engineers who make sure everything will be strong and safe. They also talk to contractors who will physically build the building, and they make sure everyone is doing their job correctly.
It's like if you were building a big Lego set - you would need to plan out what pieces you need, ask for help if you got stuck, and make sure each piece was put together correctly. The construction manager is like the master builder who makes sure everything is going according to plan.
Overall, a construction manager is a big part of building a safe and sturdy building, just like how your teacher is a big part of helping you learn and grow in school.
