6 Principles To Follow When Update Schedule from the Field.


6 Principles To Follow When Update Schedule from the Field.

With the rise of mobile adoption, the exceptions to keep the master project schedule up to date has increased. The schedule is now beyond just a reporting tool that illustrates what happens onsite. More importantly, it is now used to capture what's happening in the field to efficiently and effectively plan the remaining work on the project to ensure it finishes on time and under budget.


This webinar will cover 6 Principles to ensure that schedule updates from the field are accurate and how using onTarget’s mobile app can help teams report and analyze the data faster to make proactive decisions to help keep your project on track.




Most large projects in construction have a specific substantially completion date or specific duration in calendar days when the project must be finished.

The failure of the contractor to finish the project on time can result in heavy penalties known as liquidated damages; even worse, the contractor could be held liable for each day that the project is late. Thus, it is extremely important for the project team to keep an accurate, up-to-date schedule and to document all events, not only those that happen in the field but also in the administrative and design changes. This will help the project manager to forecast the completion date based on current updates and take corrective action if necessary.




1. To evaluate if you’re ahead or behind schedule at a specific moment in time.

2. Predict the completion date and compare it to the contractual date.

3. Document progress of project for historical reference.

4. Status each activity independently to understand the overall health of the project.


Updating a construction project schedule is a systematic, step-by-step process that includes the following steps:


1. Establish Baseline - Before updating the schedule, the contractual baseline date needs to be established. This is essentially the starting line of a race.

2. Establish the Frequency of updates and whom will validate the progress updates. A specific date and interval needs to be set. If it’s monthly the team should establish an exact date, such as the 15th of every month.

3. Establish a Data-Date per scheduling window and make sure your team gives a status to all activities that are happening in the field.

4. Only Recalculate the Schedule (step 6) when all the information has been gathered and each task’s progress has been updated.

5. Update When Major Deviations or Concurrent Delays occur. When an unexpected event outside of the schedule occur they must be documented, even though the full impact may not be known until a future date.

6. Gather all of the Information and Input the Data

  • Actual Start Date.
  • Completion Status.
  • Remaining Duration.
  • Progress to Date. (This is a judgment call based on measurable work completed, such as the number of doors installed against the total quantity required for the activity, so try to make tasks quantifiable; and if you're the one responsible for the task performance, always make sure you put eyes on the task.)
  • Actual Finish Date. 
  • Estimate the end date of activities underway to determine if they will finish on time. (This is a judgment call based on production to date and expected production to complete) 


The recalculated schedule at this step in the process is often referred to as a “half-step” schedule – that is, the baseline schedule updated with the status information with no changes to logic, original duration or any activities added or deleted.

At a minimum, the schedule needs to be updated as specified in the contract documents. For most projects, the schedule is updated monthly to correspond with the contractor’s pay applications.
