Ideally, every construction project would perfectly follow the initial blueprints. However, unexpected site conditions, design omissions, and owner requests make modifications inevitable. These modifications are managed through change orders.
While change orders can theoretically increase a project’s contract value, they often become a major financial drain for both general contractors and subcontractors. When changes are executed on-site before paperwork is signed, or when approvals sit in bureaucratic limbo for weeks, project margins erode rapidly.
Understanding the true financial impact of change orders is critical to keeping a project profitable. General contractors and subcontractors can prevent scope creep from turning into a cash flow crisis through the following strategies.
- The Trap of “Handshake” Authorizations
The riskiest approach is to focus on fixing an issue immediately and tackling the paperwork later.
Subcontractors often perform extra work under verbal agreements to keep the project moving and maintain goodwill with the general contractor. However, performing work without an executed, written change order exposes the subcontractor to massive financial risk. If the project owner ultimately rejects the change, or if a dispute arises over the final cost, the subcontractor is stuck absorbing the labor and material costs. - Tracking the Invisible Costs: Overhead and Inefficiency
When calculating the price of a change order, many contractors only factor in direct costs: raw materials and field labor hours. They fail to account for the invisible, indirect financial damages, which include:
• Disruption and Mobilization: Pulling a crew off their scheduled task to address an emergency change destroys labor productivity.
• Extended Overhead: If a change order extends the total project timeline, it means additional weeks of paying for site supervision, equipment rentals, utilities, and office overhead.
• Opportunity Cost: Capital and labor tied up in an unapproved change order prevent you from taking on new profitable projects.
Every change order proposal must include an accurate calculation of indirect costs and request an explicit extension of time, if necessary. - The General Contractor’s Dilemma: Balancing Owners and Trades
General contractors often find themselves caught in a financial pressure during the change order process. Subcontractors demand rapid approvals so they can pay for materials, while project owners and lenders may take 30 to 60 days to review and authorize the extra expense.
To mitigate this friction, general contractors must establish a strict, contractually defined change order management process. This includes setting clear deadlines for when a subcontractor must submit a change request after discovering an issue (e.g., within 48 hours) and maintaining a digital, centralized Change Order Log that updates the project’s financial forecast in real-time. - Leverage Technology to Speed Up Approvals
Waiting on paper signatures or digging through endless email threads is a major operational bottleneck. Implementing cloud-based project management software allows field superintendents to document unexpected site conditions with photos instantly, generate a change order template, and route it to the owner for digital signature while the crew is still on site. Protecting the Bottom Line
Change orders do not have to be a threat to profitability. By enforcing written agreements, calculating the true cost of project disruptions, and utilizing digital approval workflows, both general contractors and subcontractors can turn change order management into a transparent, margin-protecting process.
