Supplying materials and equipment directly to a contractor sounds like a cost control move. You buy the pipe at your negotiated rate. You have the valve in warehouse stock. You supply the equipment - the contractor installs it. You keep the margin on the materials and the contractor focuses on labour.
What most operators don't account for is the contract gap that comes with the arrangement. Owner-supplied materials - called GFM (Government-Furnished Materials) in federal work and OFE (Owner-Furnished Equipment) in industrial contexts - are one of the most consistently underdocumented areas in Alberta services MSAs. When owner-supplied material fails during installation, the dispute often ends up with lawyers involved because there's no clause that covers it.
The four risk allocation questions are always the same: Who was responsible for inspecting the material before it was handed to the contractor? When did risk of loss transfer? Did the contractor have an obligation to notify you before proceeding with defective material? And who pays to reinstall if the owner-supplied material turns out to be wrong?
Without contract language on each of these, the answer is: whoever has the better lawyer.
The four risk gaps in owner-supplied material arrangements
These four issues come up in every disputed GFM situation. Most services MSAs address none of them explicitly. Each one is resolvable with a clause that takes less than a page to draft - but only before something goes wrong.
Delivery inspection - and who signs off on it
Owner-supplied material arrives on site. Who inspects it, on what timeline, and to what standard? If the owner delivers material without a documented inspection protocol, and the contractor accepts it without flagging defects, the owner later discovers that "the contractor should have noticed" is not a valid legal position. Without a defined inspection obligation, it's unclear how much responsibility the contractor has for defects that a reasonable inspection would have caught. Without a delivery inspection clause, the owner's main argument is that a professional contractor should have known. That argument gets a lot weaker when the owner was also present on site and said nothing.
Risk-of-loss transfer - and when it actually happens
Risk of loss doesn't transfer to the contractor simply because you handed them the material. Owners often assume risk stays with them until the contractor formally accepts the material following inspection - but if the contract doesn't define the transfer moment, a court may look at when physical possession transferred - which means the owner may have lost risk-of-loss protection the moment the material left their hands, regardless of whether the contractor inspected it. The alternative outcome is equally bad: a court finds that risk never transferred because there was no formal acceptance, and the contractor is insulated from all loss regardless of how the material was handled. Without an explicit clause, neither party knows which outcome they're heading toward until litigation resolves it.
Contractor notification for defective material - before installation
The scenario: the contractor receives owner-supplied pipe. On site, the field crew notices the pipe is slightly undersized - not disqualifyingly so, but enough that installation will require modification and the end result may not match specification. The crew installs it anyway. The contractor doesn't tell anyone until the inspection fails and the entire run needs to be re-done. Without a contractor notification obligation in the MSA, the contractor has no contractual duty to flag the issue before proceeding. In practice, this means the contractor can install material they know is suspect and then claim the owner's defective material caused the outcome - while the owner argues the contractor should have stopped work and reported. If the MSA doesn't say what the contractor must do when they discover a material defect, this is exactly the dispute that follows.
Replacement and reinstallation cost - who pays when owner-supplied material fails
Owner-supplied equipment fails during commissioning. The defect is in the equipment itself - not the installation. The owner's position: the contractor installed it wrong. The contractor's position: we installed what you gave us, to the specification you provided. The dispute is about replacement equipment cost, reinstallation labour cost, and delay damages. Without contract language that allocates these costs when owner-supplied material is the cause, the allocation falls back on general negligence principles - and the argument over who caused the failure can run longer and cost more than the failed equipment itself. A simple clause that says "if owner-supplied material is defective and the defect is confirmed by independent inspection, owner bears the cost of replacement material and the direct reinstallation labour, excluding any defect attributable to the contractor's installation method" resolves this before it becomes a dispute.
What happens without a clause
Picture the typical version: the owner supplies mechanical equipment, the contractor installs it, and it fails after installation. The owner (or the owner's insurer) says the contractor installed it wrong. The contractor says the equipment was defective when it arrived.
If the contract is silent on the inspection protocol, the moment of risk transfer, and the contractor's notification obligation when defects are suspected, the parties are left to piece together intent from surrounding circumstances - the pre-installation site meetings, the email record, the field notes. That usually means expert evidence from both sides and a long, expensive argument over fault.
Nobody wants that. Four contract clauses that together take less than a page can head it off. Without them, both parties end up spending time and legal fees arguing about risk allocation that the contract should have addressed before the equipment was delivered to site.
Contracts written for a single-source arrangement - owner buys, contractor installs - almost always fail at the edge cases: defective material, wrong specification, damage in transit, failure during commissioning. Those edge cases need their own language before work starts, not after the equipment fails.
Owner-supplied material disputes frequently surface first as invoice disputes. A contractor invoicing for labour on work that failed due to owner-supplied material defects will typically invoice as if the work is complete and the failure is someone else's problem. If your MSA doesn't address reinstallation cost allocation, the contractor's position on the invoice - "we did the work we were contracted to do" - is technically defensible even when the owner-supplied material was the root cause. This is why GFM risk allocation and invoice management are connected: a clean invoice audit catches overbilling, but it doesn't resolve who owes what when the underlying dispute is about owner-supplied material. See my Contractor Invoice Red Flags guide for the billing side of this problem.
What your MSA needs to say about GFM
If you supply materials or equipment to contractors as part of your services arrangements - whether routinely or occasionally - your MSA needs a GFM section. It doesn't need to be long. It needs to answer the four questions that come up every time something goes wrong.
The structure I use with clients: a single GFM clause that covers all four risk questions, plus a Schedule C (or equivalent schedule designation) that lists owner-supplied materials for a specific work order and includes the inspection sign-off form. The clause language stays in the MSA. The schedule is work-order specific and gets updated each time GFM is involved.
- Delivery and inspection protocol - The MSA should specify that owner-supplied materials must be jointly inspected by the owner's representative and the contractor upon delivery to site. The inspection must be documented using a Delivery Inspection Record signed by both parties. Material accepted without a signed Delivery Inspection Record is deemed accepted as-is by the contractor. Material rejected at inspection must be documented and returned to the owner within [X] business days.
- Risk-of-loss transfer provision - Risk of loss for owner-supplied materials transfers to the contractor at the time of a signed Delivery Inspection Record. Until that document is signed, risk of loss remains with the owner regardless of physical location. If the contractor refuses to sign the Delivery Inspection Record, risk of loss transfer is suspended until the dispute is resolved in writing. This single clause prevents the most common argument about when the contractor became responsible for the material.
- Contractor notification obligation for suspected defects - The MSA must require that the contractor notify the owner in writing before proceeding with installation of any owner-supplied material that the contractor believes may be defective, non-conforming to specification, or damaged. Written notice must be delivered within [24 or 48] hours of discovery. If the contractor proceeds with installation of material they knew or ought to have known was defective without delivering written notice, the contractor assumes liability for the cost of removal and reinstallation regardless of who supplied the material. This clause creates the incentive to flag problems - not to install and dispute later.
- Replacement material and reinstallation cost allocation - If owner-supplied material is confirmed defective by independent inspection after installation, the owner bears the cost of replacement material and the direct labour cost of reinstallation, provided the contractor's installation method is confirmed to have been in compliance with the MSA's installation specifications. If the failure results from improper installation rather than a material defect, the contractor bears all costs. If fault is shared, costs are allocated proportionally based on the independent inspector's findings. This clause gives both parties a defined path to cost resolution without requiring litigation to establish the allocation.
- Schedule reference for work-order-specific GFM - The MSA should require that any work order involving owner-supplied materials include a completed Schedule C (GFM Schedule) that lists every item being supplied, the quantity, the specification reference, the condition on delivery, and the expected delivery date. The Schedule C is the reference document for the Delivery Inspection Record. If materials are added mid-project, an amended Schedule C is issued before delivery. Work orders that reference owner-supplied materials without a completed Schedule C should not be authorized for work commencement.
Practical notes on applying the clause
The GFM clause framework above covers the most common dispute scenarios. A few practical notes on implementation:
- Standalone supply contracts are different. If you're selling materials to the contractor and they're installing them as the contractor's own materials, this clause framework doesn't apply - you're a material vendor, not an owner supplying GFM. The GFM framework is for arrangements where the owner retains ownership of the material and the contractor is providing labour to install it.
- Transit risk needs separate coverage. If the owner is shipping material from a warehouse to a contractor's site, the transit period is a separate risk. The GFM clause covers risk from delivery to site onward. If the material is damaged in transit, that's a shipping insurance and carrier liability question - make sure your contract with your logistics provider is clear on who bears transit loss.
- The independent inspector provision is not optional. The replacement cost allocation clause depends on an independent inspector confirming the cause of failure. Without an agreed mechanism for determining fault, both parties will dispute the inspector's authority. Define in the MSA who qualifies as an "independent inspector" - a licensed engineer, a third-party testing lab, or a specific certification - so this isn't a separate argument when you need it.
- Update your SOW template. If your standard scope of work template includes language like "Contractor to install Owner-supplied [equipment/materials]" without referencing the GFM clause in the MSA, the SOW is triggering the GFM arrangement without the contract protections applying. Make sure every SOW or work order that involves owner-supplied materials explicitly references the MSA's GFM clause and includes a completed Schedule C.
One more scenario: what if the owner supplies the wrong spec?
There's a fifth risk that the checklist above doesn't cover because it's a different category: the owner supplies materials that are technically non-defective but wrong for the application. Wrong flange rating. Wrong pipe schedule. Right equipment, wrong revision of the technical specification.
When this happens, the contractor who installs to the specification they were given is not the liable party - even if the result doesn't work. The specification error belongs to the owner. The practical fix is a specification review requirement: before installation begins, the contractor must confirm in writing that the owner-supplied material matches the installation specification. If there is a discrepancy, written notice before work starts. This converts a liability question into a communication question - and communication before installation is always cheaper than litigation after it.
Add a specification confirmation step to your Delivery Inspection Record. One additional checkbox. One additional signature. That one step heads off a lot of disputes.
This is general information, not legal advice. Have your lawyer review any risk allocation language before it goes into your MSA.
Does your services MSA address GFM risk?
Most don't - and most operators don't find out until a material dispute is already underway. I review and update services MSAs for Alberta O&G and construction operators. If you supply materials or equipment to contractors as part of your services arrangements and your MSA is silent on the risk allocation, reach out before the next work order goes out.
