Critical Path Method Best Practices
Critical Path Method Best Practices. The success of any construction project relies on the scheduling process and the prioritization of tasks. This starts with identifying the most important jobs and assigning resources and responsibilities, which is where the Critical Path Method (CPM) comes into play.
Simply put, the critical path is the journey between the start and finish of your project. It’s the method you use to determine how long each required task takes before it’s finished, and includes project phases and the time periods for each phase, along with the project tasks and duration. CPM lets you identify potential delays and setbacks before they become an issue, and highlights any additional resources that can be used to move things along.
Determining each project’s CPM requires several steps. After you’ve worked out these steps, you can apply the data points to the CPM to lay out your project timeline.
- List all the tasks required to complete the project. Critical tasks are tasks with deadlines that directly impact the project timeline and float tasks are those that can be delayed without extending the project. They most likely run parallel to the critical path.
- Note the duration of each task. Determine how long each task will take to complete before you can move onto the next one.
- Identify task dependencies. Task dependency is when one task cannot start until another has been completed.
- Identify project milestones. These are the project’s major phases.
- Create a list of your project deliverables.
- Assign resources to your project tasks. Resources include people, equipment, facilities, funding, and anything else required to complete your project.
Even if you’re familiar with CPM, project managers can still apply the following best practices to help ensure success.
Account for margins of error
Whether you’ve managed one construction project or a thousand, you know that things don’t always go as planned. Your critical path needs to allow for a pivot in the case of any delays or setbacks throughout the project timeline; just try a little experimentation to see what impact they may have.
Keep this in mind: Slack is defined as the amount of time a task can be delayed without any delay in the project finish date. Free slack is the time a task can be delayed without delaying its successor task.
- Extend a task that possesses free slack. This will show you that no other tasks are affected until you exceed the free slack available.
- Extend a critical task by increasing its duration. You’ll see all the other critical tasks that would be impacted by this timeline change and reveal the total slack.
- Extending a task that only possesses total slack. This will demonstrate how other tasks will be rescheduled. Total slack is the time a task can be delayed without delaying the project finish date.
Embrace Flexibility
Staying flexible is as important as accounting for the “what if” scenarios that involve changing slack. Critical paths can change as the project continues depending on delays, resource availability, and other issues that may arise. Because you’ve already measured task duration while planning your critical path, your new duration can be easily adjusted after a delay.
Make Sure Your Critical Path Makes Sense
Once you’ve planned your critical path, run it by everyone on the team — including investors, team members, contractors, and other decision-makers. It’s crucial for the construction project’s success that everyone’s on the same page throughout the entire process. This encourages communication, collaboration, and overall teamwork.
Use Critical Path for Support
Now that the critical path is set and approved, the project manager needs to look at it as less of a “to-do” list and more of a collaboration tool to share with everyone on the team. All task deadlines should be specific and delegated to the right person. This gives the project manager a big-picture look at understanding workloads and if they’re appropriate for the delegated team member.
Update with Status Reports
Status reports (also known as milestone reports) are updates that let everyone know how things are going. Make sure each status report includes the overall progress of your project, milestones that are completed and upcoming, and any issues that you’re facing.
Any major project will have both tasks that need to be accomplished end-to-end and others that can be undertaken simultaneously. CPM scheduling identifies each step but also takes into account the best-case scenarios, likely scenarios and worst-case scenarios for each step.
At TD Wilson, we use only the best CPM software tools: Primavera P6 and P3, SureTrak (ST) and MS Project. All are highly rated and capable of delivering comprehensive reports and sophisticated analysis.
An active construction site is an exciting place of progress, precision, and potential. During the day, crews work hard to keep the project on schedule. At night, however, construction sites can be hotbeds for theft and other crimes, tarnishing crews' hard work and endangering the surrounding community. How can commercial construction teams and managers work to prevent crime in construction? Let's discuss several strategies to keep the job site, employees, and the community safe. Theft of Materials One of the most significant concerns for construction sites at night is the theft of valuable materials and equipment. Implementing secure storage areas for items such as copper wiring, tools, and machinery is essential. Additionally, installing security cameras, motion sensors, and fencing around the perimeter can deter potential thieves. Hiring security guards for overnight surveillance adds extra protection, ensuring your materials remain safe and secure. Vandalism Vandalism can cause significant damage to structures and surfaces on a construction site, leading to delays and increased costs. Consider using preventative measures such as protective coverings for vulnerable areas. Increasing visibility with adequate lighting and signage can deter vandals from targeting your site. Regular inspections and prompt repairs are essential for maintaining the integrity of your construction project and deterring further acts of vandalism. Arson Empty buildings and structures on construction sites are at risk of arson, which can result in devastating property damage and endanger nearby properties. Minimize fire hazards by storing flammable materials properly and securing ignition sources. Installing fire detection and suppression systems can help detect and extinguish fires quickly, reducing the potential for extensive damage. Maintaining clear access for emergency responders and conducting regular fire safety drills to ensure everyone on the site knows how to respond in the event of a fire is crucial.
Construction is all about trust. Owners and stakeholders trust contractors to execute the project, project managers trust their crew to work hard each shift, and crew members trust that they'll have all the materials they need to do their job successfully. The project schedule also holds much trust. Owners and stakeholders trust that the team will stick to the schedule as much as possible while communicating delays efficiently. Let's discuss best practices for making and sharing scheduling changes. Set Expectations As with any business relationship, setting expectations ahead of time is imperative. General contractors (GC) should set expectations for the rest of the management team, the crew, and anyone else working directly for their company. Then, GCs can focus on the guidelines they'll set with subcontractors they hire. Most importantly, they should set expectations with all owners and stakeholders for each project they take on. If it's been a while since a GC outlined any expectations with these groups, they should revisit the elements most important to the project's overall success. Build a Process After the team sets expectations, building a process is next. How will the project schedule be done? Where will information be stored? Where can change order requests or schedule updates be filled out? When a construction company builds a process for these steps, they are on their way to having robust construction scheduling. Using cloud-based scheduling software can help develop the scheduling process. Using the Right Software The days of paper scheduling are in the rearview mirror – the industry's improvements with digital and cloud-based scheduling tools are incredible.
