What is a WBS?
A Work Breakdown Structure (WBS) is a project management tool that breaks down a construction project into smaller, manageable parts. It helps you plan, schedule, and assign tasks more clearly.
1. Define the Project Goal
Start by writing down the main goal of your project (for example: “Build a 2-story residential house”). This is the top level of your WBS.
2. Break the Project into Major Phases or Deliverables
Divide the project into high-level phases. Examples:
- Pre-construction
- Site Preparation
- Foundation Work
- Structure
- Roofing
- Finishing
- Handover
3. Break Each Phase into Smaller Tasks
For each phase, break it into smaller, specific tasks. For example:
Foundation Work
- Excavate foundation trench
- Install formwork
- Pour concrete
- Cure concrete
Roofing
- Frame the roof
- Install trusses
- Lay roof sheeting
- Install gutters
4. Use a Numbering System
Use a hierarchical code for each task:
1.0 Pre-Construction 1.1 Site survey 1.2 Permit approval 2.0 Site Preparation 2.1 Clear vegetation 2.2 Level ground
This makes it easier to organize, track, and report progress.
5. Assign Responsibilities and Resources
Assign each task to a team member or contractor and estimate how much time, labor, and materials are needed.
6. Visualize the WBS
You can draw a WBS chart using boxes and lines (like a tree diagram), or use a table/list format. Many use Excel or software like Microsoft Project or Trello.
Why Use a WBS?
- Helps manage large projects
- Improves task organization
- Prevents missing important steps
- Supports budgeting and scheduling
- Makes it easier to assign roles and responsibilities
