Construction law is a set of rules that tell people what they can and cannot do when they are building things like houses or buildings.
Think of it like a game with rules. Just like you can't cheat in a game or break the rules, builders can't cheat or break construction law when building things.
The rules are there to help make sure that the buildings are safe and won't fall down. They also help make sure that everyone who works on a building is treated fairly and paid for their work.
Some of the rules in construction law include things like getting a permit to start building, making sure the building meets certain safety standards, and following guidelines for how to dispose of waste materials.
If someone breaks these rules, they can get in trouble and may have to pay a penalty, just like losing a turn in a game. But if everyone follows the rules, the building will be safe and everyone involved in building it will be treated fairly.
