Change Orders and Average Cost Impact to the Project (Industry Survey)

Changes are a part of the construction process with many underlying causes.

While we have all heard the average of 10% changes on construction projects, it is interesting to look at an industry study for validation.  

Change Management: Project Changes, state of the industry survey.

This study by HBRC categorized the range of contract changes and the percent of projects within that range. The average is 10% and none of the projects had 0% changes.  

Engaging key contractors to work on the project earlier will lower the amount of changes related to design conflicts while protecting the aesthetics of the design.  

Another interesting part of the study was that 43% of respondents DID NOT have a consistent process for managing changes.  

A rigorous change management process starts at the earliest stages of design development with rigorous weekly reviews.  

During construction, the definition of a change should be broadened beyond what may become a cost issue for the project owner and also managed through a rigorous weekly process such the Last Planner System.

Impacted Productivity - Five Elements of Making a Good Case
Contractors are continually faced with costly impacts to their labor productivity and schedule with many beyond their direct control. The best Project Managers know how to identify, communicate, and mitigate these impacts.
Change Order Profit Improvement
A 10% improvement in change order pricing for a $50M per year contractor will add $500K to their bottom line. This is not about simply marking up the change more, but rather, including the many costs that are typically missed or undervalued.
Impacted Productivity - Disrupted Workflow (No Schedule "Flow")
One of the biggest impacts to productivity in construction is when tasks cannot be completed as planned. When this happens frequently, it starts to impact every aspect of the contractor’s scoreboard in a negative way starting with customer satisfaction.
