The situation
The email arrived on a Thursday, three lines long, informing Seo-yeon that her structural steel supplier would not be filling the next two scheduled deliveries and could not confirm when normal supply would resume. She read it twice standing in the site trailer of her largest active project, a mid-rise job already framed to the fourth floor, and her first thought was not about the contract at all. It was about the twenty people on her payroll who showed up expecting a full week of work regardless of what a supplier three provinces away had just decided.
Seo-yeon had built her construction company over twelve years into an operation running three concurrent projects with revenue in the tens of millions, and she had never once had to pause a job for lack of materials. That track record was part of why clients trusted her with larger contracts year over year. The supplier relationship behind the steel had always been reliable enough that she had never scrutinized the underlying supply agreement closely, it had simply worked, deliveries arriving on schedule for years running.
The shortage itself traced back to a disruption further up the supply chain, at a mill the supplier depended on and had no control over. Her supplier, a manufacturing business owned by Dong-hyun, was not the source of the problem, only the party now unable to meet its commitments because of it. Seo-yeon's site superintendent, Sanja, had been the one to flag that the delivery gap would hit the framing schedule within eleven days if nothing changed, which meant the clock on this problem was measured in working days, not weeks, from the moment the email landed.
Stopping the project was not a real option. A twenty-person crew idled mid-framing does not simply resume where it left off; subtrades scheduled around the framing timeline would need to be pushed and possibly lost to other jobs, and the client's own financing carried penalties for missed milestones. Seo-yeon needed an answer within days, not after a careful multi-week review, and she needed it while three projects kept moving regardless of what that answer turned out to be.
Her first instinct was to call Dong-hyun's company directly and push for an explanation, which she did within the hour. The answer she got was polite, apologetic, and unhelpful in any practical sense: the disruption was upstream, at a mill the supplier itself depended on, and there was no firm date for resumption. Seo-yeon had worked with this supplier for six years without a single missed delivery, and the sudden shift from reliable partner to a party citing a contract clause she had never had reason to read closely left her uncertain whether this was a negotiation, a legal dispute, or simply bad luck she had no choice but to absorb. That uncertainty, more than the shortage itself, was what prompted the call to us.
What the review found
We pulled the supply agreement the same day Seo-yeon called and went straight to the force majeure clause, since that was the provision Dong-hyun's company had cited in its notice. A force majeure clause is a creature of the contract itself. It excuses performance only to the extent its own wording says so, and there is no free-standing force majeure doctrine to fall back on if the clause does not cover the event — the fallback is frustration, a much harder test to meet. These clauses vary enormously in how they are drafted: some list specific triggering events narrowly, others use broad catch-all language, some require true impossibility while others are satisfied by mere delay or hindrance, and the difference between a clause that protects a supplier and one that does not usually comes down to a handful of words most people never read closely until they need to.
The clause in this agreement was broadly drafted and, on review, genuinely covered the situation. It listed material shortages arising from upstream supply disruption as an express triggering event, required only that the supplier give prompt written notice, which it had, and did not require the supplier to prove it had exhausted every possible alternate source before invoking the clause. There was language requiring the supplier to use reasonable efforts to mitigate the disruption once it arose, and that language mattered, but it did not require the supplier to have anticipated or insured against the shortage in advance.
This was not a close call decided in Seo-yeon's favour by careful argument. The review's honest conclusion was that the clause had been well drafted from the supplier's perspective, likely by design, and that a challenge to its application would be expensive, slow, and more likely than not to fail. Seo-yeon's own supply agreement, on the other side, contained no equivalent protection running in her favour against the general contractor and the client on the mid-rise project, which meant the shortage risk, once excused at the supplier level, had nowhere else to land except on her own schedule and her own margin.
The mitigation language did give us one real lever. Dong-hyun's company was still obligated to use reasonable efforts to reduce the disruption's impact once it had occurred, sourcing partial quantities, prioritizing existing customers fairly, keeping Seo-yeon informed as circumstances changed. That obligation, modest as it was, became the main tool available once it was clear the clause itself was not going to be defeated.
We also looked closely at what remedies the agreement gave Seo-yeon for the disruption period itself, and found the answer was thin. The clause suspended the supplier's delivery obligations for the duration of the qualifying event but said nothing about compensating the buyer for downstream costs incurred while waiting, no schedule-delay damages, no price protection on a replacement source, no cap on how long the suspension could run before either party could walk away. That silence was not unusual for a standard-form supply agreement, but it meant the contract itself offered Seo-yeon almost nothing beyond the narrow mitigation duty, and any further relief would have to come from negotiation rather than entitlement.
What we did
- Confirmed the force majeure notice met the contract's formal requirements. We checked the timing and content of Dong-hyun's written notice against what the clause required, so that if there was a technical defect we could raise, we would find it immediately rather than after the window to act on it had passed. There was none, which told us early that a technical challenge was not the path forward.
- Pressed the supplier on its mitigation obligation rather than the triggering event. We wrote to Dong-hyun's company requesting a specific accounting of what alternate sourcing efforts were underway and what partial quantities, if any, could be redirected to Seo-yeon's projects, using the reasonable-efforts language in the clause as the basis for pushing harder than a simple acceptance of the shortage would have allowed.
- Sourced a secondary supplier in parallel, without waiting on the first conversation to resolve. Because the timeline Sanja had flagged left no room for a slow negotiation, we advised Seo-yeon to open a parallel track sourcing steel from a second manufacturer immediately, accepting a premium price for expedited delivery rather than losing more framing days waiting to see what Dong-hyun's company could produce.
- Reviewed the schedule impact against the general contractor's own agreement. We checked whether Seo-yeon's contract with the general contractor gave her any excuse or extension for a supply disruption of her own, and found the protection there was limited and narrower than the clause the supplier had relied on. That gap meant we needed to manage the client relationship directly through early disclosure and negotiation, rather than rely on contractual cover that turned out not to exist.
- Renegotiated the milestone dates directly with the general contractor. Rather than letting the delay surface as a missed deadline discovered on inspection, we helped Seo-yeon present the situation early, with documentation of the supplier's force majeure notice and the steps already taken to mitigate it, framing the request as proactive rather than an excuse. That approach secured a short, documented extension that avoided the financing penalty tied to the original milestone.
- Negotiated a partial cost concession from the original supplier. Once alternate sourcing was underway, we used the mitigation-efforts obligation to negotiate a modest price adjustment on the delayed portion of the original order, on the basis that the supplier's own conduct during the disruption fell short of what reasonable efforts should have produced, without conceding that the force majeure claim itself was invalid.
- Documented the entire episode for the other two active projects. Because Seo-yeon's other jobs relied on materials from suppliers with similarly drafted clauses, we pulled and reviewed those agreements while the lessons from the steel shortage were still fresh, flagging which of them carried comparable force majeure and mitigation gaps. That review meant the same kind of disruption elsewhere would not catch her by surprise a second time, or require relearning the same lesson under a second live deadline.
- Advised on renegotiating the supply agreement's force majeure terms for future orders. Once the immediate crisis was contained, we reviewed what a tighter clause could look like for renewal, including a defined cap on how long a suspension could run before Seo-yeon could source elsewhere without penalty, and a clearer standard for what mitigation efforts the supplier owed her. That gave her a concrete negotiating position for the next contract rather than a general sense that the old clause had been unfair.
The outcome
The framing schedule slipped by a little over two weeks rather than the month or more it would have lost waiting on the original supplier alone, largely because the parallel sourcing track started immediately instead of after negotiations with Dong-hyun's company had run their course. That gap cost Seo-yeon a real amount, in the low six figures, between the premium paid for expedited alternate steel and the subtrade rescheduling fees the delay triggered, an outright loss the force majeure clause left her with no contractual route to recover from the original supplier.
The partial price concession negotiated on the delayed original order offset a portion of that cost, and the extension secured with the general contractor avoided the financing penalty that would otherwise have compounded the loss significantly. The client relationship survived the delay intact, in part because Seo-yeon brought the problem forward early with documentation rather than letting a missed date arrive unexplained.
Seo-yeon was direct about how she read the outcome afterward. This was not a case where good legal work turned a loss into a win; the clause held, the cost was real, and no amount of careful drafting after the fact could undo money already spent on expedited materials. What the review and the parallel sourcing did was keep the loss contained to one project's schedule and one line of extra cost, rather than letting it cascade into missed deadlines across all three active jobs or a damaged relationship with a general contractor she expected to work with again.
The relationship with Dong-hyun's company continued after the disruption ended, though on different footing. Deliveries resumed within about six weeks once the mill-level shortage cleared, and the two companies renewed their supply agreement for the following year with the tighter suspension-cap terms in place. Seo-yeon said afterward that she now reads every force majeure clause she signs, in every contract, before the next order goes in, a habit she wished she had had a year earlier.
What you can learn from this
- Read your suppliers' force majeure clauses before you need them. A broadly drafted clause can genuinely excuse a supplier, leaving you to absorb the schedule and cost impact with no recourse.
- A force majeure clause that excuses performance often still requires reasonable mitigation efforts. That obligation, not the underlying event, is frequently where real leverage remains.
- When a business cannot pause while a dispute is sorted out, start parallel practical solutions immediately rather than waiting for the legal question to resolve first.
- Bringing a delay to your own client early, with documentation, protects the relationship even when the underlying cause was outside your control.
- Check whether a risk in one contract is mirrored in your other active agreements. A shortage that hits one supplier relationship can expose gaps in several at once.
