Top Construction Scheduling Mistakes

Hello World! Welcome Friends!Work has begun as usual, and there has been a two-month success streak with no labor or material shortages. This is considered a strike of good luck for the site’s project managers; things should undoubtedly be on time. Right?

Considering the project is only halfway completed, the project began only three short months ago, and the project end date is thirty days from now, there may be some delays in the construction scheduling process.

The possibilities of on-time completion do not seem feasible, even with overtime. Even if the labor hours were doubled and the material availability was assured, the timeline still does not correlate with the realistic timelines needed for the timeline completion date. So, what now?

The above scenario could be a real doozy to correct, with a high probability of not succeeding with an on-time and within-budget construction project. The timeline was created unrealistically in the first place, and the construction project contract states there are fees for every day over the completion date. Project Managers and Stakeholders could face time and money issues, topped with a very strenuous completion, leaving some bitter business relations behind when the project is actually completed.

This scenario is a good explanation as to why it is important to develop and maintain an effective construction schedule. This guide will cover common mistakes in construction scheduling and how to avoid or minimize any issues in a construction schedule.

The Role of Construction Scheduling in a Successful Project

A Construction Schedule is the lifeline and sustainability of a successful construction project. It serves as a timeline of when, where, and who will complete a task. The entire schedule is broken down into tiny puzzle pieces called tasks, and each one needs to be implemented in chronological order until task completion. Within these tasks, budgets are put in place, along with resource allocation efforts.

Without effective project scheduling implementation, the consequences can lead to construction project failure accompanied by several issues. Complications can include:

Delays: Project Completion & Resource Allocation

Consequences: Task delays, project disputes, cost overruns, and budget breaches.

The above scenario will experience some consequences of a poor construction schedule. The completion date faces many days of delay. The fees required for late completion can be costly each day past the date of completion. Materials could imply delays, creating more time for fees. Labor shortages could occur due to overwork and burnout, costing more money in overtime payments and more time waiting on labor hour replacements. Delays can occur due to the need for overlooked permits, costing even more time and money. At the end of the project’s completion, disputes between stakeholders will likely be on the horizon. The entire construction project faces complete failure due to a poor and unrealistic construction schedule.

Common Mistakes in Construction Scheduling

A good way to avoid major construction project failure is to become familiar with the most common mistakes and avoid creating the mistakes all over again. Understanding these mistakes and the consequences behind them will help prevent the issue altogether. Let’s take a look at the mistakes to avoid:

Unrealistic Timelines

Setting deadlines that are too tight or unfeasible, as you can see above, is definitely not the way to go. Rushing estimates can also fit in an unrealistic timeline schedule. Be sure to be realistic and account for the consequences that can occur, such as increased pressures, quality issues, and project decline. By being thorough and realistic, you can avoid all the hassles and missed milestones.

Poor Communication Among Stakeholders

The lack of proper coordination between the project managers, subcontractors, and the team had to occur in the above scenario. They were three months into a project with a 50% completion rate and only had 30 days left to execute total project completion. Even though they had a two-month success streak with no labor or material shortages, the lack of communication in the beginning obviously needed to be keener on the planning process. Adjustments should have been made in the beginning. Miscommunications and misunderstandings between all stakeholders and the team are apparent in this scenario. Communication is key. Delays in work handoffs and rework due to schedule misalignments can also be consequences of poor communication or lack thereof.

Overlooking Resource Constraints

Failing to account for labor, equipment, and material availability fits this common mistake category. The above scenario would have already accounted for this and avoided the crunch time that had to be implemented, driving a double-time work day. Burnout in overworked labor hours would not have been a possibility. Many issues arise if tasks are not scheduled without ensuring sufficient heavy machinery, equipment, materials, and personnel. Of course, the consequences are time and money. Fighting idle time and cost overruns is a major setback when the project is not fully prepared.

Ignoring Contingency Planning

Not including a secondary plan or allowing additional time for unforeseen delays such as labor, materials, and supply chain breaches, as well as uncontrollable delays such as weather and legal operations, are considered tasks of the critical path. Not allowing any slack time due to the sometimes deemed inevitable can cause a serious snowball effect, crashing into serious project setbacks.

Inadequate Use of Scheduling Tools

Underutilizing or not using advanced tools like CPM scheduling software or relying on outdated methods can be the broken pillar of a construction schedule. Although Excel spreadsheets are still very helpful, they cannot hold a light to a dedicated project management software such as Primavera P6. The consequences can be a complete failure in the construction scheduling process. Using the Excel method only will limit visibility into each task, its dependencies, and being able to adequately track progress.

Failure to Regularly Update the Schedule

Treating the schedule as just a light timeline rather than the dynamic life force of a construction project leads to destruction. Failure to adjust schedules frequently after scope changes or delays can cause some serious consequences, such as teams working with outdated timeline data. Chaos is the end result when teams and stakeholders do not know what to expect or the next step to take accordingly.

Avoiding These Mistakes

To avoid these common mistakes can be as simple as doing the opposite of the above. Here are some important factors to consider in an effective construction schedule process.

Set Realistic Timelines

Collaborate with experts and ask questions to get a more approximate estimate to develop achievable schedules. Take into account all possibilities of delays and add additional time. The consequences of not taking this step were in relation to the above scenario. If this step had been taken, on-time project completion would have been a success.

Foster Clear Communication

Remember, communication is key, and by implementing weekly meetings and progress reports, everyone can stay on point. By using centralized management platforms, all stakeholders can stay informed and be in the loop in case of delays or accountabilities that may occur.

Account for Resource Availability

Conduct resource planning during the initial scheduling phase. Build flexibility into the construction schedule to implement resource adjustments when needed.

Include Contingency Buffers

Adjust for extra time that may be needed for high-risk tasks. To identify high-risk tasks, use risk analysis assessments and allow additional padding when needed. See which areas have a critical path and account for them ahead of the action, and adjust as the project continues.

Leverage Modern Scheduling Tools

Adopt and fully utilize CPM software, Gantt charts, or BIM-integrated tools. If needed, all staff should be trained to use and fully utilize advanced scheduling platforms effectively. The more knowledge base held in this utilization, the more effective construction project scheduling will become.

Regularly Review and Update Schedules

Schedule reviews should be as important as or more important than the materials of a construction project. Just as it’s a routine to work on the project daily until completion, schedule reviews need to be a routine and a mandatory part of project management. As soon as changes occur, review and adjust timelines immediately.

The Importance of avoiding common construction scheduling mistakes is apparent in this guide. Taking an extra step to be thorough in the beginning stages of project scheduling is crucial.

Giving accountability to the unseen challenges ahead while fostering a superb line of communication through effective scheduling software will ensure success. All stakeholders and teams can stay in the loop and continue moving forward.

By implementing these practices and avoiding the pitfalls, the success of a timely, well-budgeted project is on the horizon. Assess current scheduling practices, adopt these in this guide, and avoid these mistakes. The construction scheduling process will convert to success every time
