What is Pull Planning in Construction? A Complete Overview
Oded Ran, CEO and Co-Founder of Clue since 2019, expertly integrates AI and data tools to revolutionize construction equipment management and maintenance, positioning Clue as a premier software choice in the construction industry.
Scheduling construction tasks has always been an issue for project managers to handle, with resources getting delayed and maintenance tasks taking up project time, affecting the project timeline.
This is why more and more contractors rely on construction pull planning to help schedule things accurately.
Pull planning starts with the end goal and then works backward to define steps for the scheduling process.
What is a Pull Plan in Construction?
Pull planning is a part of the lean construction process known as the Last Planner System (LPS). Stakeholders and managers collaborate to schedule milestones and then work backward to define the steps to achieve the milestones.
Traditional construction scheduling methods often fail to connect project milestones with the tasks assigned to different teams.
Pull planning addresses this issue by promoting accountability for the functions and highlighting potential milestone delays.
Some individuals who are actively involved in construction pull planning include
- Project Managers,
- Foremen and Supervisors
- Trade Contractors,
- Designers and Engineers,
- Schedulers,
- Owners or Clients
- Facilitators or Coaches.
Pull planning, essentially a part of the Last Planner System, is used in lean construction and has gained popularity among contractors, with approximately 15% of the contractors now using pull planning techniques.
Pull Planning vs. Push Planning: The Differences and the Benefits
Push and Pull planning are contrasting scheduling and planning techniques used mainly in construction.
In pull plan construction, the control approach is centralized, whereas in push planning, a decentralized approach is used where teams are responsible for their tasks without collaboration among teams.
Push vs. Pull Planning in Construction
Analyzing the aspects of push and pull planning in construction it is easy to see while these approaches are a part of the construction process, they are complete opposites of one another.
You can check out the table below to better understand the different aspects of the planning processes and where they differ or are similar.
Basic Principles of Construction Pull Planning
Successfully executing construction pull planning requires you to examine and follow certain principles, which are crucial for planning and implementing the new strategy.
Plan Backwards
Rather than asking,
What is the next step?
as is often the case for traditional planning, pull planning requires answering the more important question of
What should be done before the next step?
This method keeps project managers focused on deadlines and quality goals, helping them plan to cut waste and handle unexpected issues effectively.
Collaboration with Teams
Construction pull planning requires one team member to be physically or digitally available during the planning process.
This helps gather input from all the teams without omitting any potentially important detail.
One of the benefits of pull planning on a construction site is incorporating the perspectives of all the teams.
This fosters teamwork and allows the stakeholders to create better plans.
Commitment to the Process
Construction pull planning promotes accountability. As different teams participate in the planning process, they can define timelines and milestones based on their abilities.
Also, in this case of planning, if an issue arises, you can quickly identify the team responsible and work together to find a solution.
Monitor for Continuous Improvement
Regular pull planning meetings at project beginnings let team members discuss what's effective and what isn't.
This involvement promotes sharing ideas and feedback, improving how plans and construction are done over time.
The Construction Pull Planning Process
The construction pull planning process involves the following key steps to ensure efficient project management:
1. Set Milestones
Set milestones to establish significant points or events marking project progress, such as completing foundation work or structural framing.
Setting milestones early in the planning stage allows you and your teams to understand the project timeline and how to achieve different milestones.
2. Sequence Activities
Sequence activities logically to determine the order in which tasks should be performed.
This will help you ensure efficient resource use and minimize delays.
For example, interior finishes like painting and flooring should follow tasks such as drywall installation and electrical wiring.
3. Identify Constraints
Identify constraints early, including material availability, weather conditions, and regulatory approvals, to anticipate challenges and develop mitigation strategies.
Different issues can lead to other project delays, from the project being halted by a day due to a delivery delay to a long delay resulting from equipment breaking down.
Anticipating and identifying these constraints can help save project managers a lot of time and effort.
4. Assign Tasks
Assign tasks to the relevant teams based on their skill set.
When the planning process is done, the facilitator for the meeting takes the plans and assigns the tasks on a spreadsheet, sharing the document with the teams so they can review what tasks have been assigned and what is expected of them.
How to Prepare for Construction Pull Planning
Construction pull planning meetings can be divided into three main segments: pre-meeting preparation, the meeting itself, and post-meeting takeaways.
Here are some of the main activities that would be happening during the three stages of a construction pull planning method.
1. Pre-Meeting Preparation
- Understand Project Goals: Review project scope, objectives, and timelines.
- Identify Participants: Determine critical stakeholders and their roles.
- Select Facilitator: Assign a facilitator to guide the meeting.
- Prepare Agenda: Create a structured agenda with clear goals and topics.
- Gather Information: Collect project schedules, resource availability, and constraints.
2. During the Meeting
- Introduction and Overview: Clarify the purpose and objectives of the meeting.
- Establish Ground Rules: Set expectations for participation and decision-making.
- Review Project Details: Present scope, schedule, milestones, and dependencies.
- Collaborative Planning: Engage participants to break down tasks, identify dependencies, and sequence work.
- Create Pull Plans: Define tasks, assign responsibilities, and set target dates.
- Document the Plan: Record action items, responsibilities, and timelines.
3. Post-Meeting Follow-Up
- Distribute Meeting Notes: Share documented pull plan and meeting outcomes.
- Monitor Progress: Track progress against the pull plan and adjust as needed.
- Schedule Follow-Ups: Plan future meetings to review and update the pull plan.
A great example of construction pull planning can be seen in the case study on the Warren County project conducted by HGC Construction, which was quite complex.
Still, by using pull planning, the teams could streamline all the processes and foster a sense of teamwork among the contractors.
Digital Tools for Pull Planning
If looking at the picture above intimidates you, it's time you switched from traditional pull planning and filled your walls with Post-it notes to a more cohesive construction pull planning method: digital pull planning.
Using digital tools for pull planning in construction streamlines the planning process, enhances collaboration, improves decision-making, and increases overall project efficiency and success.
Advantages of using Digital Tools for Construction Pull Planning
