Productivity Loss and Rework Costs from Poorly Managed Change Orders
3 verified sources
Definition
Research cited in change order best‑practice guidance shows that a high volume of changes reduces labor productivity by 10–30%, and late changes can trigger extensive rework and cascading schedule impacts, significantly increasing project cost beyond the face value of the change.[2][7][8] When these indirect and consequential costs are not reflected in change order pricing, the contractor absorbs the overrun.
Key Findings
- Financial Impact: If total change order value equals 10–15% of a $50M contract (~$5M–$7.5M), a 10–30% productivity hit on affected work can easily translate into several hundred thousand to multi‑million‑dollar unpriced labor and overhead costs per project.[2][7][8]
- Frequency: Weekly
- Root Cause: Frequent or late design and scope changes disrupt planned sequences, cause crews to stop and restart work, and force work in less efficient conditions; contractors often fail to quantify and include these indirect labor and disruption costs in the change order, leading to internal cost overruns.[2][7][8]

Related Business Risks
Administrative Burden of Change Order Pricing Consuming Estimating and PM Capacity
One study example shows two hours of project staff time at $50/hour to prepare a change request, costing $100 before review; scaled across hundreds of change orders on a typical nonresidential portfolio, this equates to tens to hundreds of thousands of dollars annually in indirect labor and lost opportunity capacity.[9][8]
Unpriced and Late-Priced Change Orders Eroding Billable Revenue
For a $50M nonresidential project, change orders typically represent $5M–$7.5M; under‑recovery of only 10–20% due to weak pricing/approval controls equates to ~$500K–$1.5M per project, i.e., low‑ to mid‑seven figures annually for a contractor running multiple projects.[2][7][8][9]
Rework and Defects from Informal or Rushed Change Order Implementation
Given change orders commonly total 10–15% of contract value, even a modest 5–10% rework rate on changed work can represent low‑ to mid‑six‑figure quality‑related costs on a $50M–$100M nonresidential project.[2][7]
Slow Change Order Approval Extending Time to Cash and Tying Up Working Capital
On a project where change orders equal 10–15% of a $50M contract (~$5M–$7.5M), it is common for millions in change order value to remain unapproved for months, effectively acting as an interest‑free loan to the owner and materially worsening the contractor’s cash conversion cycle.[2][7][9]
Disputes and Claims from Non‑Compliant Change Order Procedures on Public/Institutional Projects
While the specific dollar impact varies per dispute, on large nonresidential and transportation projects change order claim disputes routinely involve millions in questioned costs and can lead to partial or full disallowance of compensation, effectively converting extra work into an unfunded cost burden on the contractor.[7][2]
Inflated or Opaque Change Order Pricing Enabling Abuse and Disputes
For owners on large nonresidential projects where change orders total 10–15% of contract value (~$5M–$7.5M on a $50M job), even a 5–10% premium from opaque or excessive markups on changes can mean several hundred thousand dollars in avoidable spend.[2][6][8]
