The Subcontractor's Guide to Change Orders

If you are a subcontractor, change orders are a fact of life. Plans change, owners add scope, general contractors ask for extras, and unforeseen conditions pop up on nearly every project. The problem is that most change order processes are designed from the general contractor's perspective, not yours. As a sub, you are often the last to be informed, the first to absorb extra costs, and the one left fighting for payment months after the work is done. This guide is written specifically for subcontractors who want to handle change orders professionally, protect their margins, and get paid faster.

Why Subcontractors Struggle with Change Orders

The subcontractor's position in the construction chain creates unique challenges when it comes to change orders. You do not have a direct relationship with the owner, so you are relying on the general contractor to communicate changes accurately and approve your pricing promptly. That adds a layer of delay and potential miscommunication to every change.

Many subcontractors also face an uncomfortable power dynamic. The GC controls your payment, your schedule access, and your future work opportunities. Pushing back on unclear directives or insisting on proper documentation can feel risky, especially on competitive bid work where the GC has other subs ready to step in. This dynamic leads many subs to perform extra work first and try to document it later, which is the single biggest mistake you can make.

Understanding what a change order actually is and how the formal process works gives you the foundation you need to navigate these situations with confidence.

Know Your Contract Terms

Before you ever set foot on a jobsite, read the change order provisions in your subcontract. Every subcontract has specific clauses that govern how changes are handled. These clauses define critical details: how changes must be requested, what notice periods are required, how pricing is calculated, what markup is allowed, and what happens if you perform work without prior written approval.

Pay close attention to the notice requirements. Many contracts require you to submit written notice of a potential change within a specific timeframe, sometimes as short as 48 hours, or you waive your right to additional compensation. Missing this deadline means you could perform thousands of dollars of extra work and have zero legal basis to demand payment.

Also look for "constructive change" language. A constructive change occurs when the GC directs you to perform work that is outside your scope, even if they do not formally call it a change order. Your contract may give you the right to treat verbal directives as change orders, but only if you follow the proper notification procedures. Know these provisions before you need them.

When to Submit a Change Order

Submit a change order anytime you are asked to perform work that falls outside your contracted scope. This includes obvious changes like additional rooms, upgraded materials, or new systems, but it also includes less obvious situations that subcontractors frequently absorb without compensation.

If the GC changes your sequence and forces you to remobilize, that is a change. If coordination issues with other trades require you to rework completed installations, that is a change. If the drawings conflict with field conditions and you need to modify your approach, that is a change. If you are asked to work overtime to make up schedule delays caused by others, that is a change.

The rule is simple: if it is not in your original scope of work, do not do it for free. Being helpful and flexible is good business, but consistently absorbing extra work without compensation is not being helpful. It is being taken advantage of.

What to Include in Your Change Order

A subcontractor's change order needs to be thorough enough to justify the cost but concise enough to get a quick approval. Include the following elements in every change order you submit.

Reference the directive. Cite the specific RFI response, drawing revision, or verbal instruction that triggered the change. Tie your change order to a documented event so there is no question about why the work is necessary.

Describe the scope clearly. Explain what work you will perform, what materials are required, and how it differs from your original scope. Be specific. "Additional electrical work" is vague. "Install 12 additional duplex receptacles in Building B second floor per revised drawing E-201 Rev. 3" is defensible.

Itemize the cost. Break the price into materials, labor hours, equipment, overhead, and markup. Use current supplier quotes for materials and your contractually agreed labor rates. If your contract specifies a markup cap, show the calculation. For guidance on getting the numbers right, read our article on how to price a change order.

State the schedule impact. If the change adds time, say so. If it does not, say that too. GCs need this information to manage the overall project schedule, and documenting it protects you from acceleration claims later.

Negotiating with General Contractors

Negotiation is a normal part of the change order process. GCs will often push back on pricing, and that is expected. The key is to negotiate from a position of documentation, not emotion. When your change order has clear scope descriptions, itemized costs, and references to the original contract, the conversation stays professional and productive.

If the GC asks you to reduce your price, ask them to specify which line items they disagree with. This shifts the conversation from "your price is too high" to a factual discussion about specific costs. If they want you to reduce your labor hours, ask them to explain their estimate. If they challenge your material prices, share your supplier quotes.

Never agree to start work on a change order with pricing "to be determined later." This is where subcontractors lose the most money. Once the work is complete, your negotiating leverage drops to nearly zero. The GC has no urgency to agree to your price because the work is already done. Get the price agreed to in writing before you begin, even if it means a short delay. To avoid escalation into a full-blown conflict, review our 7 strategies for avoiding change order disputes.

Protecting Yourself with Documentation

Documentation is your insurance policy. Every conversation about extra work should be followed by a written confirmation. If the superintendent gives you a verbal direction in the field, send an email that same day summarizing what was discussed and what you intend to do. If they do not correct your summary, it becomes part of the record.

Keep a daily log that notes any out-of-scope work, delays caused by other trades, and directives received from the GC's team. Take photographs of conditions that trigger changes. Save every email, text message, and revised drawing. This documentation trail is what separates the subcontractors who get paid from the ones who write off losses.

Track every change order by number, date submitted, amount, and approval status. On a busy project, it is easy to lose track of pending change orders, especially when you have multiple outstanding at the same time. A simple tracking system ensures nothing falls through the cracks and gives you a complete picture of your financial exposure at any point in the project.

Go Digital, Get Paid Faster

The subcontractors who handle change orders best are the ones who make the process easy for the GC to approve. If your change order arrives as a clear, professional, itemized document with a signature line, it moves through the approval chain faster than a handwritten note or a vague email.

Digital tools eliminate the friction that slows down the change order process. Instead of printing, scanning, and emailing documents back and forth, you can create a change order on your phone from the jobsite, send it for electronic signature, and have a signed PDF in your records within minutes. The faster the change order is signed, the faster you can include it on your next pay application.
