Construction projects rarely stay exactly the same from start to finish. Plans shift. Site conditions change. Materials get substituted. An owner asks for something new. A contractor finds work that was not visible at tender. A trade is told to move faster, come back later, or redo a portion of the job. When those changes are not documented properly, payment disputes often follow.
We see this issue often in our construction law and builders liens services. Owners, contractors, subcontractors, and trades come to us when a project has become tense over extra work, unpaid invoices, scheduling impacts, or arguments about what was actually approved.
In many of those files, the dispute did not begin with a major legal battle. It began with a change that seemed minor at the time.
If you work in construction in British Columbia, you already know how quickly a simple site instruction can turn into a serious disagreement. One person thinks the work was included.
Another believes it was an extra. One side says the price was discussed. The other says there was never a firm agreement. By the time the issue reaches our office, the project record may be incomplete and the relationship between the parties may already be damaged.
That is why change orders deserve their own discussion. We have covered related issues in our posts on construction contracts in BC and construction delays in BC, but change orders raise a distinct set of practical problems. When the scope changes, the paperwork needs to change too.
What is a change order?
A change order is a written record of a change to the original contract scope, price, timing, materials, method, or sequence of work. In plain language, it is the document that confirms what is changing and what the parties have agreed to do about it.
On a busy project, people sometimes treat a change order like a formality. It is not. It is one of the clearest ways to prevent confusion later. A proper change order helps answer questions before they grow into disputes:
- What work changed?
- Who asked for the change?
- Was the change approved?
- How much does it cost?
- Does it affect the project schedule?
- Who is responsible for the added time or expense?
Without clear answers, a project can drift into a conflict that is much harder to manage.
Why extra work disputes happen so often in BC projects
Extra work disputes are common because construction decisions are often made under pressure. Work is moving. People are trying to keep crews productive. A consultant gives direction. A superintendent wants a problem solved right away. Someone says they will sort out the paperwork later.
Later is where trouble starts.
We regularly see a few patterns repeat themselves.
Verbal instructions replace written approvals
Someone on site says, “Go ahead,” and work starts. Weeks later, nobody agrees on what those words meant. Was it full approval? Was it permission to price the work only? Was it a temporary instruction subject to a later sign-off? If nothing was written down, the answer may become a factual dispute.
The extra work is not described clearly
A change order that says “additional work as discussed” is not likely to help much when payment is challenged. If the description is vague, both sides may claim the wording supports them.
Cost is left unresolved
Sometimes the parties agree that there is a change, but they do not agree on the price before the work begins. That creates obvious risk. One side expects a fair adjustment later. The other expects the cost to stay low or believes it was included already.
Time impacts get ignored
Even a small change can affect scheduling, access, sequencing, labour availability, or completion dates. If time is not addressed when the scope changes, the project can end up with a second dispute layered on top of the first.
The contract process is skipped
Many contracts set out a specific change procedure. That may include written notice, pricing requirements, approval steps, or timelines. When parties stop following their own contract, they make it harder to prove what was agreed.
Why change orders need more attention than they usually get
In our experience, change order disputes are rarely only about paperwork. They are usually about money, timing, and trust. Once one side feels it is not being heard or paid properly, the entire project relationship can shift.
For owners, poor change management can mean surprise invoices, budget overruns, and frustration over work they did not think they authorized.
For contractors and trades, poor change management can mean performing substantial work and then fighting to get paid for it.
For everyone involved, weak documentation can make resolution slower and more expensive.
That is one reason we encourage clients to treat project records seriously from the start. The more clearly the file tells the story, the easier it is to assess legal rights if a dispute develops. Where the record is thin, the dispute often turns on conflicting memories, informal texts, and partial email chains.
What a strong change order should cover
No single form fits every project, but most strong change orders should address the same core points.
1. A specific description of the revised work
The change should identify what is being added, removed, revised, substituted, or deferred. Clear language helps everyone understand whether the work falls inside or outside the original contract.
2. The pricing structure
The change order should record whether the added cost is fixed, estimated, based on unit rates, or billed on a time-and-material basis. It should also address markups, taxes, labour categories, equipment, and materials where those details matter.
3. The timing impact
If the revised work affects project deadlines, milestones, or sequencing, that should be stated clearly. If the parties agree there is no schedule adjustment, that should also be documented.
4. Approval from the right person
This is critical. Many disputes arise because someone gave site direction without actual contractual authority. The person approving the change should be the person authorized under the contract, or at least someone whose authority is clear from the project structure.
5. Supporting records
Drawings, sketches, revised specifications, meeting minutes, site instructions, photos, and emails can all support the change order and make later arguments less likely.
A complete record will not solve every problem, but it can greatly improve your position if payment is disputed later.
What happens when the work is done without a signed change order?
This is one of the most common questions we hear.
Sometimes extra work is completed before the paperwork is finalized. In some cases, the work was clearly requested and everyone knew it was outside the original scope. In others, the parties never had the same understanding at all.
When there is no signed change order, several issues may become important:
- whether the work was actually extra under the contract
- whether the other side requested or accepted it
- whether there was an implied agreement to pay
- whether the parties had a pattern of working without formal paperwork
- whether the supporting records back up the claim
That does not mean payment can never be recovered without a signed document. It does mean the dispute may become more complex, more expensive, and more dependent on the surrounding facts. In some cases, the issue may connect with lien rights, holdbacks, or broader payment protection concerns discussed in our post on builders liens in BC.
Common project scenarios that lead to change order disputes
We often see disputes grow out of practical project events like these:
The owner requests a design upgrade mid-project
The contractor proceeds quickly to avoid delay, but the final invoice is challenged because the added work was never priced and approved in writing.
Hidden site conditions are discovered
Work needs to change after demolition or excavation reveals something unexpected. Everyone agrees the problem must be dealt with, but nobody pauses to document the revised scope and cost.
A consultant gives direction on site
The contractor follows the instruction, then later faces an argument that the consultant did not have authority to approve the cost increase.
A subcontractor performs added work based on a conversation with the general contractor
When payment gets tight, the extra work is questioned and the subcontractor is left trying to prove what happened.
The project schedule compresses and labour costs rise
The parties focus on finishing the job and do not fully record how the acceleration affected cost. Later, they dispute who should bear that expense.
These are not unusual problems. They are part of why early legal review can be valuable before positions harden.
Practical steps you can take to reduce extra work disputes
A good construction file is built one decision at a time. The following habits often make a real difference.
Use a clear contract at the start
A strong contract should explain how changes are requested, priced, approved, and recorded. It should also deal with schedule impacts and notice requirements.
Confirm site discussions in writing
If there is a verbal direction or site conversation, follow it up promptly in writing. Even a short written confirmation can help preserve an accurate timeline.
Do not start major extra work on assumptions alone
Where possible, price and approval should be settled before the work begins. If that is not realistic, the interim arrangement should still be documented.
Keep organized project records
Daily reports, photos, schedules, meeting notes, invoices, and correspondence all matter. Those records often become central if a dispute later moves toward negotiation, mediation, or court.
Watch the payment side closely
If unpaid change work starts piling up, it is wise to get advice early. Delay can affect both leverage and available remedies. Our commercial civil litigation page is also relevant where a construction payment dispute expands into a broader contract conflict.
Get legal guidance before the file becomes entrenched
When parties stop communicating well, even a manageable problem can become expensive. Early legal advice can help you assess the contract, the paperwork, the risk points, and the most sensible next steps.

Why this topic fits a separate discussion
Change orders are related to contracts, delays, and builders liens, but they are not the same thing. They sit at the point where project management and legal risk meet. That is exactly why they deserve focused attention.
A contract sets the framework. A delay claim looks at time and responsibility. A lien may protect payment rights. A change order dispute often touches all three, but it begins with a more basic question: what changed, who approved it, and how was it supposed to be paid for?
When that question is answered clearly, many larger disputes can be avoided. When it is answered poorly, the problem can spread across the project.
