The Importance of Progress Measurement 

Successfully executing projects hinges on many variables. Yet, the fundamental question that must be answered before any proactive or prescriptive measures can be implemented is this: Where are we today? Deceiving in its simplicity, this question often proves difficult to answer accurately. 

As such, the objective and realistic measurement of physical progress during a construction project is a key element for successful project management. Progress measurement is an input directly used to help determine the earned value of a project and forecasts such as cost at completion and estimated finished date. These outputs can be used to help apply corrective action to keep costs and schedule under control.  

Sources of Progress 

 

Sources of Progress

 

The method for measuring the physical progress made on-site must reflect the correct phase of the project. In this post, I will illustrate how to determine physical progress during the design phase of a project from sources such as: 

  • A 3D model built with a 3D design tool 
  • Electrical, piping, or other schematic deliverable created with 2D design tools 
  • Other types of documents available within the document management tool 

I will also explain how to consolidate this information into a project control tool to evaluate the progress of each cost structure individual element. 

Establish Weighted Milestones 

There are multiple ways to measure progress on a project. In my opinion, the most valuable method to use during the design phase is the weighted milestone methodThe principle is to establish a list of milestones that make the design life cycle of each type of object measurable, then the weighted properties to be completed to meet each milestone. The advantage of this method is that it measures how the work is progressing between two different milestones and, thus, provides realistic information on the progress. 

The diagram below is an example of a model for a given object type: 

 

Progress Measurement Weighted Milestones

 

If we consider a state of progress at a time T for a work package that contains several types of objects, then the consolidation formula is: 

 

Progress Measurement Consolidation Formula

 

To consolidate the progress of all the engineering work packages, the hourly budget for each package (established from the estimate) is considered a good weighting factor. The consolidation formula is then:

Automation Through Integration 

On complex projects, the enormous number of moving parts (sometimes literally) makes accurate progress measurement challenging. Even today, it’s often compiled manually meaning that information is delayed and highly subject to potential errors.  To dramatically increase speed and accuracy, and therefore be an aid in improving project performance, organizations must strive to automate progress measurement as much as possible. 

The successful automation of such a process requires close integration between design tools and project control tools. This is one of the advantages of utilizing software that delivers a full lifecycle project ecosystem, where data is shared seamlessly between tools. This type of integration is available between Hexagon PPM’s different solution suites: 3D and VisualizationEngineering and SchematicsProcurement, Fabrication and ConstructionAsset Lifecycle Information Management, and Enterprise Project Performance. The screenshot below illustrates the calculation of the earned value based on the percentage of completion and the weightings:

Imagine having accurate and up-to-date progress information at the push of a button. What kind of impact do you think that would have on your projects?

Parts II and III of this series will focus on progress measurement during the procurement and construction phases of the project.

    An Excellent Blog to describe the progress measurement. When do we see the next parts?

  2. Thanks, Amrita! Parts 2 and 3 will be coming in August. Stay tuned! 🙂
