Take the Sydney Opera House, for example.

It was expected to take just four years to build, but ended up taking 14.

It was expected to cost just $7 million to build, but ended up costing $102 million.

 

--

On a construction project, we do the same thing.

We order materials and engage skilled labor to put it all together.

 

In each project, we face unique challenges that we may never have faced before.

 

---------------------------

 

 

 

Planning is the process of determining what needs to be done and how to do it.

Scheduling focuses just on the time based project outcomes.

 

Sure, in the pre-construction phase, we could create a project schedule with 10,000 lines showing

 

We want the master project schedule to cover key activities and linkages and add detail as works progress

The master project schedule typically covers levels 1 to 3 and is managed by the project planning team.

The level 4 to 6 schedules are typically created by delivery teams and a highly detailed schedules showing

### Simplified Explanation and Feedback

#### Steps for Developing a Work Breakdown Structure (WBS):
1. **Understand Key Inputs**: 
   - Make sure you are familiar with the design and requirements (like construction drawings). Watch videos, for example, about street light footing construction to visualize the process.

2. **List Major Deliverables**:
   - **Mobilization**: Preparing the site and resources.
   - **Earthworks**: Digging and preparing the ground.
   - **Electrical Works**: Setting up conduits and wiring.
   - **Concrete Works**: Pouring and setting the foundation.
   - **As-built/Completion**: Finalizing and documenting the project.

3. **Breakdown Sub-Activities**:
   - For each major deliverable, break it into sub-tasks (e.g., excavation, formwork, pouring concrete, etc.). Assign each sub-task an **ID**, **criteria**, and **description** to create a detailed WBS dictionary.

#### Feedback:
- **What went well**: The WBS structure is clear, and the major deliverables are well-defined. The layering concept is useful for understanding hierarchical breakdowns.
- **Improvements**: The sub-activities could include more detailed criteria to clarify expectations for each phase. Adding **timelines** or **resource allocation** would make it more actionable.
