Alright kiddo, let me explain to you what Engineering, Procurement, and Construction (EPC) means.
When we want to build something like a house or a bridge, we need to make a plan first. This is where the "Engineering" part comes in. Engineers use their math and science skills to design and plan how the thing we want to build will be built. They decide what materials will be used and how all the different parts will fit together.
Once the plan is done, we need to get all the materials we need to build it. This is where the "Procurement" part comes in. Think of procurement like going to the store to buy everything we need to build our thing. We need to buy bricks, wood, nails, cement, and lots of other things. The people in charge of procurement make sure we have everything we need and that it's delivered to the right place at the right time.
Now we have all the materials we need, we can start building! This is where the "Construction" part comes in. The workers use the plan that the engineers made to start building the thing we want. They use the materials that the procurement people got for them and put them all together to make the thing we want, like a house or a bridge.
So, EPC is a way to make sure that we have everything we need to build something, from the planning stage to getting all the materials, to actually building it. It's like having a really good plan before you start building a puzzle, making sure you have all the right pieces, and then putting it all together to make a final picture.
