For specialty trade contractors, the change order process sits at the center of two of the most pressing business challenges in construction: getting paid accurately for work performed, and maintaining the GC relationships that drive repeat business. New research from Clearstory and Dodge Construction Network, Optimizing the Change Order Process for Specialty Trade Contractors, surveyed US general contractors and specialty trade contractors on their current practices, workflows, and outcomes.
The findings document where specialty contractors are losing time, losing revenue, and in some cases straining GC business relationships, and reveals what the firms managing the process well are doing differently.
What Is the Change Order Process for Specialty Trade Contractors?
For specialty trade contractors, the change order process involves documenting, pricing, submitting, and receiving approval for work performed outside the original contract scope. This includes:
- Solicited changes: Formal requests from the GC to price additional scope
- Unsolicited changes: Work directed verbally or informally in the field, outside original contract scope
- Time and materials (T&M) work: Field-directed work tracked on a cost-plus basis, billed against actual labor hours and materials
Each type requires accurate field documentation, internal pricing, formal COR submission to the GC, and GC approval before payment can be processed. Breakdowns at any stage create delays, disputes, and revenue exposure.
How Long Does It Take to Get a Change Order Approved?
According to the Dodge research, the average time from COR submission to a signed change order returned from the GC is 26 days. 43% of specialty trade contractors report that authorization takes three weeks or more.
Approval delays are driven by several factors:
- Pricing disputes, cited by 64% of contractors as a leading cause of change order disagreements
- Scope disputes on 52% of change orders
- Incomplete documentation on 47% of change orders
- Late submittals on 30% of change orders
More than half of all CORs require two or more revision cycles before reaching approval, with each cycle extending the time between work performed and payment received.
How Long Does It Take Specialty Contractors to Submit a COR After Work Is Done?
Before a COR reaches the GC, specialty contractors must complete an internal process: capturing T&M work in the field, pricing it, assembling backup documentation, and submitting it. According to the Dodge research, the average time from a signed T&M tag in the field to a fully priced COR submitted to the GC is 22 days. More than a third of trade contractors say this internal process takes three weeks or more.
Key contributors to that timeline include:
- 65% of specialty contractors still use paper T&M tags
- Only 12% use digital T&M tags
- Few contractors have integrated digital workflows connecting field documentation to COR pricing and submission
- Manual pricing, spreadsheet-based COR logs, and email-based submission create multiple points of delay
The practical effect: by the time a COR reaches the GC, the work it describes may already be three to four weeks old. When the GC's approval timeline is added, the total gap between work performed and change order authorization can approach two months.
What Are the Most Common Causes of Change Order Disputes for Trade Contractors?
The Dodge research identifies five leading causes of change order disputes:
- Pricing disputes: 64% of contractors cite this as a top cause
- Scope disputes: disagreements over what work was included in the original contract
- Incomplete documentation: insufficient backup to support the requested amount
- Late submittals: CORs submitted after GC pricing deadlines
- Approval delays: slow GC turnaround that extends risk exposure for trades
A compounding factor: 97% of specialty trade contractors sometimes begin work before a change order is officially approved, and 42% do so more than half the time. On fast-moving jobs, it’s the norm. But it means CORs are frequently documenting completed work, often after the fact, without the real-time backup that supports clean approval.
How Often Do GCs Not Pay the Full Change Order Amount?
More than half of GCs (57%) report that they do not pay the full requested amount on more than 20% of the change orders they manage. The most common reasons GCs cite for withholding or reducing payment:
- Disputed pricing: 66%
- Insufficient backup documentation: 53%
- Disputed root cause: 51%
- Lack of agreement that work was in or out of scope: 47%
- Disputed quantities: 32%
For specialty contractors who have already performed the work and funded the labor and materials, a downward-negotiated or rejected change order represents direct revenue loss. 77% of specialty contractors have had to write off change order work as bad debt.
What Are the Financial Impacts of Poor Change Order Management on Trade Contractors?
The Dodge research documents several direct financial impacts on specialty trade contractors:
Cash flow: 83% of specialty contractors report that the change order process negatively impacts their cash flow. The combination of slow internal processing (average 22 days) and slow GC approval (average 26 days) means capital is routinely tied up in completed, unbilled, or unapproved work.
Bad debt write-offs: 77% of specialty contractors have written off change order work they were unable to collect. Work that was performed but not documented thoroughly enough to survive a GC dispute becomes unrecoverable revenue.
Escalated disputes: 48% of specialty contractors have had change order disputes escalate to arbitration or a legal process, adding cost and time well beyond the original disputed amount.
Lost GC relationships: 27% of specialty contractors have stopped working with a specific GC due to change order issues. For trade contractors who rely on repeat GC business, losing a customer relationship over a process failure is a significant long-term cost.
How Does Poor Change Order Management Affect Trade Contractor Teams?
The operational and human impacts on specialty contractor staff are significant. The Dodge research found:
- 98% of specialty contractors report the change order process is increasing stress levels for their staff
- 96% say it is decreasing job satisfaction
- Staff time consumed by manual COR processing, revision cycles, and dispute resolution reduces capacity for project execution and business development
A workflow problem significant enough to affect culture and retention has costs that extend well beyond the projects where change order issues originate.
What Tools Do Most Specialty Contractors Use to Manage Change Orders?
Most specialty trade contractors are managing change orders with general-purpose tools rather than purpose-built solutions. According to the Dodge research:
- 72% primarily rely on email for change order communication
- 50% primarily use spreadsheets to manage the change order process
- 65% manually compile PM reports from the field to track change order KPIs
- Only 11% primarily use shared software for change order communication with GCs
Digital adoption across specific change order functions is low. Fewer than 30% of trade contractors frequently use digital processes for key functions including tracking allowance and contingency balances, integrating CORs with ERP and project management software, or using digital tools to standardize labor and material rates.
Only 12% use digital T&M tags, meaning the vast majority of T&M documentation still begins on paper in the field.
What Separates Top-Performing Specialty Contractors in Change Order Management?
The Dodge research segmented specialty contractors by how systematically they manage their change order process. The performance gap between the top tier and the rest is measurable across every key outcome.
Top-performing specialty contractors are significantly more likely to:
- Use digital T&M tags rather than paper (25% vs. 10%)
- Use standardized COR templates (85% vs. 68%)
- Actively track change order KPIs including outstanding exposure, days to approval, and write-off percentage
- Use one shared change order log accessible in the cloud by both GC and trade teams (30% vs. 13%)
- Integrate change order requests with ERP and project management software (45% vs. 16%)
The result is faster internal processing, stronger documentation, fewer revision cycles, and better outcomes on disputes and negotiations. 54% of trade contractors agree that better visibility into their change order revenue exposure would help them proactively address financial risk. The tools and practices that close these gaps exist. The difference between firms that control their change order outcomes and firms that absorb them is whether they're being applied consistently.
What Do Specialty Contractors Want From Change Order Technology?
When the Dodge research asked trade contractors what would drive adoption of digital change order management solutions, the leading factors were:
- Ease of use (96% of GCs cite this as a top factor; trade adoption criteria align closely)
- Multi-device accessibility: usable on laptops, tablets, and phones in the field
- Affordability
- Easy adoption for subtiers, field users, and GCs
- Integration with existing financial software
Trade contractors also expressed strong appetite for better financial visibility. 54% agree that greater visibility into potential financial challenges related to change order revenue would help them proactively mitigate risk, a capability that purpose-built change order management solutions are designed to provide.
Would Industry Standardization Help the Change Order Process?
Yes, according to both specialty contractors and GCs. The Dodge research found that 78% of contractors believe a standardized, efficient, and transparent digital change order process would have meaningful positive impact. One in three predicts the impact would be high or transformative.
Specific benefits contractors believe standardization would deliver:
- Improved approval speed for change order requests (64% of trades, 70% of GCs)
- Improved accuracy of change order requests (53% of trades, 73% of GCs)
53% of trade contractors also expressed support for an industry-wide standard operating procedure for change order documentation, a signal that the industry is ready for a more consistent approach.
Frequently Asked Questions: Change Order Management for Specialty Trade Contractors
How long does it take to get a change order approved from a GC? According to Dodge Construction Network research, the average time from COR submission to a signed change order returned from the GC is 26 days. 43% of specialty contractors report the process takes three weeks or more.
How long does it take to submit a COR after T&M work is completed? The average time from a signed T&M tag in the field to a fully priced COR submitted to the GC is 22 days, according to the Dodge research. More than a third of trade contractors report this internal process takes three weeks or more.
Why do GCs reject or reduce change order payments to trade contractors? The most common reasons GCs cite are disputed pricing (66%), insufficient backup documentation (53%), disputed root cause (51%), lack of agreement that the work was in scope (47%), and disputed quantities (32%).
What percentage of specialty contractors start work before a change order is approved? 97% of specialty trade contractors report sometimes beginning work before a change order is officially approved. 42% do so more than half the time.
What is a T&M tag in construction? A T&M (time and materials) tag is a field document used to record labor hours, materials, and equipment used on work performed outside the original contract scope, on a cost-plus basis. T&M tags must be signed by the GC's representative in the field and then converted into a priced change order request for billing. Most specialty contractors still use paper T&M tags, which contributes to processing delays and documentation disputes.
How does the change order process affect specialty contractor cash flow? Specialty contractors fund T&M work upfront -- labor, materials, equipment -- before submitting for reimbursement. The average combined internal processing time (22 days) and GC approval time (26 days) means capital can be tied up in completed, unapproved work for nearly two months before authorization is received. 83% of specialty contractors report that the change order process negatively impacts their cash flow.
What percentage of specialty contractors have stopped working with a GC due to change order issues? 27% of specialty trade contractors report having stopped working with a specific GC due to change order issues, according to the Dodge Construction Network research.
Summary: The State of Change Order Management for Specialty Trade Contractors
Specialty trade contractors face a two-sided gap in the change order process: slow internal processing that delays submission, and slow GC approval that delays authorization. The combined effect is a billing cycle that can stretch close to two months from the day work is performed -- a direct cash flow challenge for firms funding work upfront.
Poor documentation is the most preventable driver of disputes, rejected payments, and write-offs. Yet most specialty contractors are still managing their change order process on paper and in spreadsheets, without the visibility into their own exposure that would allow them to address risk before it compounds.
The firms managing this well are doing it through consistent use of digital tools, standardized processes, and active KPI tracking. The full Dodge report documents where the gaps are, what the top performers are doing, and what the path forward looks like for specialty contractors ready to close them.
