Advanced Work Packaging (AWP) and Lean Construction are two popular approaches to improving the efficiency and effectiveness of construction projects. Both approaches have their own unique strengths and weaknesses, and the best approach for a particular project will depend on its specific needs and characteristics.
What is Advanced Work Packaging (AWP)?
AWP is a project planning and execution methodology that focuses on breaking down a project into smaller, more manageable work packages.
These work packages are then planned and executed in a sequenced manner, with careful attention to coordination and communication. AWP is often used in conjunction with Building Information Modeling (BIM) to create a virtual representation of the project that can be used to plan and coordinate the work.
What is Lean Construction?
Lean Construction is a philosophy and set of tools that focus on eliminating waste from construction projects.
Waste can take many forms, such as waiting, defects, overproduction, and unnecessary transportation. Lean Construction practitioners use a variety of tools and techniques to identify and eliminate waste, such as value stream mapping, 5S, and Just-in-Time (JIT) delivery.
Comparison of AWP and Lean Construction
The following table compares AWP and Lean Construction across a number of key criteria:
Criteria | Advanced Work Packaging (AWP) | Lean Construction (LC) |
Focus | Work packaging | Continuous improvement |
Planning | Milestone planning | Last Planner System® (LPS®) |
Execution | Workface planning | Daily huddles, pull planning |
Collaboration | Integrated project teams | Collaborative culture |
Waste elimination | Identifies and eliminates waste | Focuses on reducing waste and non-value-added activities |
Technology | Uses BIM and other project management tools | Uses BIM and other lean tools |
Benefits | Improved planning and execution, reduced costs and delays, increased quality | Increased efficiency and productivity, improved communication and collaboration, reduced waste |
Advantages of combining AWP and Lean Construction approaches
Combining AWP and Lean Construction approaches can offer a number of advantages, including:
Improved planning and execution: The prescriptive approach of AWP can be combined with the flexibility and adaptability of Lean Construction to create a planning and execution process that is both efficient and effective.
Reduced waste and non-value-added activities: Lean Construction focuses on identifying and eliminating waste from construction projects. When combined with AWP, this can lead to significant reductions in costs and delays.
Increased efficiency and productivity: By combining the work packaging and planning principles of AWP with the continuous improvement focus of Lean Construction, teams can achieve significant gains in efficiency and productivity.
Improved communication and collaboration: Both AWP and Lean Construction emphasize the importance of communication and collaboration. When combined, these approaches can help to create a more cohesive and productive project team.
Increased quality: The focus on waste elimination and continuous improvement in Lean Construction can help to improve the quality of the finished product. Additionally, the work packaging and planning principles of AWP can help to ensure that work is completed correctly and on time.
Examples of how to combine AWP and Lean Construction approaches
Here are some examples of how AWP and Lean Construction approaches can be combined:
Use BIM to create a virtual representation of the project for planning and coordination purposes. This can help to identify and eliminate potential conflicts and problems before they occur.
Use the Last Planner System® (LPS®) to schedule and track work at the workface level. This can help to improve coordination and communication between different stakeholders, and ensure that work is completed on time and to a high standard.
Use daily huddles and pull planning to sequence work and identify potential constraints. This can help to keep the project on track and avoid delays.
Use 5S and Just-in-Time (JIT) delivery to reduce waste and improve efficiency on the workface.
Use integrated project teams and collaborative work practices to promote communication and collaboration between different stakeholders.
Conclusion
Combining AWP and Lean Construction approaches can offer a number of advantages for construction projects. By combining the strengths of both approaches, teams can improve planning and execution, reduce waste and non-value-added activities, increase efficiency and productivity, improve communication and collaboration, and increase quality.
When choosing which approach to use for a particular project, it is important to consider the project's specific needs and characteristics. However, in many cases, combining AWP and Lean Construction approaches can be the best way to achieve the desired results.
