Engineering Productivity Measurements (Archived)

RT-156 Topic Summary
RT 156


Research Team 156 was established to determine a valid measurement approach to drive improvement that present-day design tools lack.  

This research discovered that the majority of participating companies were utilizing engineering productivity measurements that have not evolved with the design technology being utilized. Progress was being reported based on drawing or specification status. Prior efforts to increase engineering productivity utilizing these same standards only led to shifting work from engineering to the field which results in additional field labor and cost. 

RT-156 recommends the implementation of an engineering unit based measurement system that takes into consideration the quantities designed instead of the drawings created. Few participating companies are currently utilizing this approach, and of the ones who are – their primary goal is to manage quantity creep on a project.

With further implementation of the design unit approach, additional consistency can be added to controlling projects across all phases.                        

Key Findings and Implementation Tools

1 : Existing Performance Evaluation

The current engineering productivity systems most actively utilized in the industry are based on engineering deliverables, e.g., isometrics, P&IDs, etc. This has been driven by the pre-modeling era of project document generation.

RT-156 found that with the widely adopted 3D modeling execution, a better representation of engineering progress can be correlated with the engineering units, e.g., lineal feet of pipe, cubic yards of concrete, tons of steel, etc. (RR156-11, p. 87)

2 : Engineering Productivity Model

Several factors differentiate effective engineering productivity within industrial projects. These factors consist of project scope and complexity, input quality, and output deliverable quality. (RS156-1, p. 11, Figure 3)

3 : Progress Measurement System

Through the RT-156 recommendations projects will see significant potential for developing a universal progress measurement system to control project through their lifecycle (Detailed Design, Procurement, Construction, Startup, and Commissioning). (RS156-1, p. 15)
