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.
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
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.
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.
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.
Successfully executing construction pull planning requires you to examine and follow certain principles, which are crucial for planning and implementing the new strategy.
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.
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.
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.
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 involves the following key steps to ensure efficient project management:
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.
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.
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.
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.
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.
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.

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.
Utilizing digital tools in construction pull planning comes with significant benefits. Some advantages of using digital tools in pull planning include:
However, the initial cost of integrating detailed information into building designs is a significant challenge. This investment ensures precise and permanent data within project plans.
Some popular examples of construction pull planning software include:
Pull planning allows you to optimize your workflows by breaking down projects into manageable tasks with clear timelines. This structured approach helps teams work more efficiently toward milestones.
Pull planning involves all the possible stakeholders in a collaborative planning session. This enhances communications and aligns objectives with goals. It also helps reduce misunderstandings and improve overall project coordination.
Pull planning minimizes delays and reduces resource wastage by identifying dependencies and sequencing tasks effectively. This lean approach focuses on eliminating unnecessary activities and optimizing resource allocation.
Changes in strategies most commonly come with challenges. Project managers might face a few common challenges with construction pull planning.
Change comes with resistance. The same is true for pull planning. Many team members and stakeholders may resist adopting pull planning due to unfamiliarity or comfort level with traditional project management practices.
Overcoming these resistances requires clear communication of the benefits and gradual implementation.
Coordinating schedules and activities among multiple trades and subcontractors can be challenging, especially when dependencies are complex. Effective communication and detailed planning are essential to mitigate coordination issues.
Digital tools for construction pull planning are a new concept that can scare many contractors and teams. Implementing these tools comes with its own challenges, such as learning curves, compatibility issues, and overall investment costs.
Overcoming these challenges requires training, support, and showing the value of the technology in streamlining processes.
Pull planning, a crucial part of lean construction's Last Planner System (LPS), emphasizes team members' collaboration to plan projects efficiently.
This approach boosts project efficiency and enhances teamwork and commitment, leading to higher-quality work and stronger partnerships.
Some may initially hesitate to adopt pull planning, especially if it is not done correctly. However, the process proves its value by consistently delivering projects on time and sometimes even ahead of schedule.
If you are new to pull planning, seeking advice from industry peers can help integrate it smoothly into current and future projects. The positive results may make you wonder why you didn't use it sooner.
Pull planning aims to create a team environment where collective problem-solving is critical. This proactive approach ensures ongoing improvements in project efficiency as teams effectively anticipate and address challenges. This, in turn, helps ensure successful and smooth project execution.
Pull planning enhances project efficiency by involving all stakeholders in collaborative scheduling sessions. It fosters accountability, improves communication, and ensures realistic schedules that adapt to project realities.
Project teams use pull planning to gather stakeholders, visualize task dependencies with tools like sticky notes, and create detailed schedules backward from milestones to ensure efficient project execution.
Pull scheduling is collaboratively creating a project schedule based on pull planning principles. It involves breaking down tasks, identifying dependencies, and adjusting the schedule to meet project milestones.
To form a pull strategy, identify stakeholders, schedule collaborative planning sessions, use visual tools to map out tasks and dependencies, build the schedule backward from milestones, and continuously review and refine based on project progress for efficient execution.
