### 1. Building a building

A new building needs hundreds of people, tonnes of material and many months\. A construction project manager is the person who keeps all of it working together\. Let's follow one building from idea to opening day\.

Drag the scene to look around\. Pinch or scroll to zoom\.

### 2. It starts with a goal

First, the owner decides what they need, where it will go and how much they can spend\. The project manager checks that the plan is possible\. Surveyors hammer stakes into the ground to mark exactly where the building will stand\.

### 3. Plan the work

Architects draw the plans, and the city checks them and gives permission, called a permit\. Then the manager breaks the job into tasks and puts them in order on a schedule called a Gantt chart\. Each bar is one task, and its length shows how many weeks it takes\.

### 4. Find the critical path

Some tasks must wait for others: the roof can't go on before the frame is up\. The longest chain of waiting tasks, shown in orange, is called the critical path\. Try a delay and watch the red finish flag\.

The garden has float: spare weeks it can slip without making the whole project late\. This schedule is a simple example\.

### 5. Build in the right order

Now the crews arrive\. The concrete foundation goes in first, then the steel frame rises floor by floor\. A tower crane lifts the heavy beams\. Big cranes can lift around 12 tonnes near the tower, but only about 2 tonnes at the far tip\.

### 6. Keep checking

Checking doesn't wait until the end\. Every week the manager compares the real work with the plan, shown by the blue line on the schedule\. They also watch the money spent and the quality of the work, and adjust the plan when something changes\.

### 7. Safety every day

Everyone on site wears a hard hat and a bright vest so they are protected and easy to see\. In the United States, hard hats are required wherever something could fall from above\. Keeping every worker safe is part of the manager's job\.

Hard hat colours often show a person's role, but each company sets its own colour code\.

### 8. Finish and hand over

At the end, inspectors check the building and a punch list of small fixes is cleared\. Lights, heating and water are tested, the crane leaves, and the keys go to the owner\. Scope, time, money, quality and safety, all kept in balance: that is project management\.
