Industrial contractor unpaid invoices in Alberta carry a problem that ordinary construction receivables do not. A turnaround compresses a large volume of work into a few weeks, against a contractual chain that may sit several parties deep, and the lien clock starts the day you demobilize rather than the day you invoice. By the time a payment problem becomes obvious, a substantial share of the window has already gone.
Key Takeaways
- Turnaround work concentrates receivable exposure into a short period.
- The lien clock runs from your last day of work, not from your invoice date.
- The 90-day lien period attaches to wells and well sites, so confirm your scope.
- Lien rights generally exist even where you contracted with an EPC rather than the owner.
- Your contractual claim runs against the party that hired you, not the facility owner.
- Turnaround documentation is unusually strong, and it is your best asset in a dispute.
This article provides general information and is not legal advice. Lien eligibility and deadlines depend on the facts of each contract and should be confirmed with counsel.
Why Turnaround Receivables Behave Differently
Alberta’s Industrial Heartland sits directly northeast of Edmonton across Strathcona County, Fort Saskatchewan, Sturgeon County, and Lamont County. The upgraders, refineries, and petrochemical facilities concentrated there run planned turnarounds that draw contractors and trades from across the region, which is why Edmonton area businesses carry more of this exposure than anywhere else in the province.
Concentrated Exposure
A turnaround is not a normal job. Crews mobilize on a fixed date, work compressed shifts against a schedule measured in days, and demobilize on completion.
That concentration changes the risk profile. On a typical commercial ledger, one bad account is absorbed across dozens of others. A turnaround ledger has no such diversification, because a large share of the year’s billing can sit with a small number of counterparties from a small number of jobs.
The Chain Is Longer Than You Think
Turnarounds are executed through layers. An operator engages an EPC or a prime maintenance contractor, who engages specialty trades, who engage their own subcontractors and equipment suppliers.
You may be several parties removed from the entity that owns the facility and the money. Each layer adds a point where payment can stall, and none of the layers below the first has a direct contract with the operator.
The Lien Deadline Most Turnaround Contractors Get Wrong
This is the most consequential misunderstanding in Heartland work, and it costs contractors the remedy entirely.
Do Not Assume the 90-Day Period Applies
Alberta’s Prompt Payment and Construction Lien Act sets a general lien registration deadline of 60 days, with 90 days applying to work relating to an oil or gas well or well site, and 90 days for concrete work.
Contractors working in the energy sector frequently assume the 90-day period covers everything they do. The longer deadline is written to attach to wells and well sites specifically, which means whether a given facility scope falls inside it is a question about your particular work rather than about the industry you operate in.
That question needs answering by counsel, before the turnaround rather than after. Until it is answered, the safe operating assumption is 60 days, because the two errors are not symmetrical. Registering early costs nothing. Registering late costs the remedy entirely. Firms working with builder’s liens regularly can resolve the question quickly for a given scope of work.
Demobilization Is Your Trigger Date
The lien period runs from the last day services were performed or materials were furnished, or from the date the work was abandoned.
On most construction projects that date is genuinely ambiguous, since work trails off through deficiencies and callbacks. On a turnaround it is unusually clean. You demobilized on a specific day, it is recorded, and everyone agrees on it.
That clarity cuts both ways. It removes any argument about when the clock started, and it also removes any argument that it started later. A contractor who demobilizes in April, invoices in May, and begins chasing payment in June has already spent a meaningful portion of a 60-day window.
Who You Can Lien and Who You Can Claim Against
These are two different questions, and conflating them sends contractors after the wrong party.
Lien Rights Do Not Require a Direct Contract
Lien rights attach to the improvement and the interest in the land rather than depending on privity with the owner. A subcontractor engaged by an EPC or a prime contractor generally holds lien rights against the project even with no contract with the facility owner.
What that does not do is convert the owner into your debtor for the full balance. The lien is security, and the owner’s exposure through it is bounded by the statutory framework rather than by what you are owed.
When the Prime Was Paid and You Were Not
An operator pays the prime contractor. The prime contractor does not pay you. The instinct is to approach the operator, who has the money and a reputation to protect.
That instinct is usually misdirected. The operator has discharged its obligation to the party it contracted with, and the failure sits one layer down. Your contractual claim runs against the entity that hired you, supported by whatever lien rights you preserved and, where the project falls under the prompt payment regime, whatever payment obligations flow down the chain.
Where a prime contractor is genuinely insolvent rather than merely slow, the timing becomes urgent, since unsecured creditors of a failed contractor recover partially at best. Establishing which situation you are in is the first useful step, and a commercial debt collection assessment usually surfaces that faster than continued calls to accounts payable.
Turnaround Documentation Is Your Advantage
Turnaround work generates better records than almost any other construction activity, and most contractors underuse them.
Daily time sheets are signed. Labour, equipment, and material tickets are approved on site, often daily. Scope changes are documented because the schedule demands it. Mobilization and demobilization dates are recorded by the facility. Equipment on hire is logged.
That record is why turnaround disputes resolve faster than ordinary construction disputes when they are pursued properly. Assemble the package while the crew is still available to explain it, rather than eight months later when the superintendent has moved to another contractor. Where heavy equipment was on hire during the shutdown, the rental records and the receivable are separate claims that both need preserving.
What to Do Before You Demobilize
Five steps, and four of them happen before the job ends:
- Confirm the exact legal entity that engaged you and that it matches your contract and your invoices.
- Record your demobilization date formally, since every deadline runs from it.
- Close out tickets and dailies on site, signed, before the crew leaves.
- Calculate your lien deadline immediately on the assumption of 60 days unless counsel has confirmed otherwise for your scope.
- Escalate at the halfway mark. An unpaid turnaround invoice at day 30 needs a decision rather than another follow-up.
Contractors also working wellsite scopes should track their deadlines separately, since oil and gas work at a well or well site is addressed differently under the Act than other work.
Common Questions About Turnaround Receivables
The questions below come up on most stalled shutdown accounts.
Do I have 60 or 90 days to lien turnaround work?
That depends on your specific scope. The Act sets a general 60-day period, with a 90-day period written to apply to work relating to an oil or gas well or well site. Have counsel confirm which applies to your work, and default to 60 days in the meantime, since the consequence of assuming the longer period and being wrong is losing the remedy.
Can I lien if I contracted with the EPC and not the operator?
Generally yes. Lien rights attach to the improvement rather than requiring a direct contract with the owner, though your contractual claim still runs against the party that hired you.
The operator paid the prime contractor. Can I claim against the operator?
Usually not for the full balance, since the operator has met its obligation to the party it engaged.
How long do I have to sue if the lien window closed?
Alberta’s Limitations Act gives most claims two years from when you knew or ought to have known you had a claim. Losing the lien removes the security, not the debt.
The prime contractor says they will pay after the next turnaround. Should I wait?
Payment tied to a future project is not a payment arrangement, it is a delay with a story attached. Get a specific date and amount, and treat continued vagueness as the answer.
Protect the Balance While the Window Is Open
Turnaround receivables reward contractors who calculate deadlines from demobilization and act inside them. They punish the ones who wait for the invoice cycle to run its course, because by then the short clock has largely expired.
If you are carrying unpaid balances from a shutdown, the first question is which accounts still support lien registration and which have moved past it. Bison Credit Solutions recovers industrial and construction receivables across Alberta on a contingency basis, with no charge where nothing is collected, and works accounts through third-party collections once the legal position is established.
