A PERT schedule allows for flexibility because it considers both best- and worst-case scenarios.ĭisadvantages: PERT is a complicated construction scheduling technique that can be time-consuming. Calculations provide the best estimate of the time required to complete each task.Īdvantages: PERT gives project managers a clear picture of critical tasks that must be completed on time to keep the project on schedule. PERT starts by identifying project tasks and their durations and lays out the milestones indicating progress. It’s valuable on complicated projects and can be a more visual representation than a CPM. PERT is a construction scheduling technique used to estimate project duration, identify risks, and identify most likely activity durations when there’s uncertainty about the estimates. Program evaluation and review technique (PERT) Also, CPM software can be intimidating to those learning to schedule projects.ģ. It helps project managers more confidently allocate funding and allot resources to complete the project on time.ĭisadvantages: Because the algorithm runs the show, it can seem overly complex and complicated. CPM helps project managers and participants understand not just which activities are driving the end date of a project, but also which ones “could” jump onto the critical path based on how much float they have. These activities are categorized as having zero “float,” meaning the amount of time a task can be delayed without driving out a project’s end date. By recalculating the math with different algorithms and computer programs, CPM includes an estimate of the fastest possible time to finish a specific activity.Īdvantages: CPM highlights which activities drive the end date of a project. This technique develops the initial picture of a project and identifies the resources and time required to complete each milestone, as well as how the set goals relevant to the project. No construction scheduling technique is faster or more efficient at building an initial contract schedule-provided that the inputs are accurate and represent how the work should be done. This technique will often result in project delays and costly decisions based on outdated information.ĬPM is the tried-and-true workhorse algorithm. Sharing an Excel template means there will be multiple versions of the original document with various changes sent via email. It’s also not a collaborative scheduling technique. For one thing, every cell in the spreadsheet must be manually updated, a laborious process requiring constant hands-on attention the moment something on a project changes. This scheduling technique can be most valuable if only one person is working in the Excel document.ĭisadvantages: Most construction planners worth their salt don’t do their core planning and scheduling practice in an Excel template. Since Excel is bundled into Microsoft Office, it’s user-friendly, inexpensive, and accessible. And about all you need to know is how to work in a spreadsheet format.Īdvantages: Excel templates are appropriate for very small, simple projects (even ones bigger than Spot’s doghouse). Excel templates are a simple way to stay organized and keep the details of a construction project together. Cloud-based construction scheduling techniques are secure, easy to use, and build collaboration among all parties.Ĭonstruction schedules kept in Excel have their limitations, but this remains an extremely popular method. Manual processes can lead to costly errors.The appropriate project scheduling technique will vary by project complexity and size.A combination of methods may be appropriate for the job. Each technique comes with pros and cons.Choosing the right scheduling technique can make the difference between meeting deadlines and budgets and missing them.But the tools team members use to support that process may be analog-each team member receives a letter in the mail with an invitation-or digital-each member gets an invitation to a digital planning and scheduling session using software. The first step in that process is to invite the project team together. They’re process frameworks (a series of steps or things to do in a specific order) and they’re also tools (the how, where, and what you may use to capture or manage those processes).įor example, a construction firm develops a schedule by gaining the input of others. With several techniques to choose from, selecting the right one can improve efficiency, communicate important milestones, define resource allocations, and improve the productivity of the project.Ĭonstruction scheduling techniques are a combination of a few things. What Are Construction Scheduling Techniques?Ĭonstruction scheduling techniques help ensure that a project will run smoothly.
