## Bottom line: what Stonebriar must do, in order, this week

1. **Do not pull the remaining warranty crew and do not stop work to “let them sweat.”**  
   If Stonebriar is directed to continue during a dispute, the continue-performance rule makes a voluntary stoppage a default. That is the single most strategically dangerous move available this week.

2. **Record a mechanics lien now for the safe amount, not the full $1,328,000.**  
   The safe amount is **$410,000**, assuming the last two applications are properly earned, submitted, and undisputed. Do not include the unapproved $918,000 DSC/delay claim in the lien unless a portion is already approved, undisputed, and actually due. An overstated lien risks forfeiture and fees.

3. **Respond to the default notice immediately, within the 7-day cure window, with a detailed cure plan and a no-admission reservation of rights.**  
   The response should say the south-run slippage is caused by differing site conditions and owner/GC-caused stoppage, not Stonebriar breach, and it should attach a recovery schedule.

4. **Demand the $410,000 and require Corestone to prove the pay-if-paid condition.**  
   Demand proof that Stonebriar’s applications were submitted to the owner, that the owner has not paid, and that Corestone did not cause the nonpayment. If Corestone received owner payment or caused the nonpayment, the pay-if-paid defense fails and prompt-payment interest should be demanded.

5. **Preserve and assert the DSC claim now, but do not treat the late formal letter as the only notice.**  
   The March 3 email is weak on its face because it went to the superintendent, not the designated representative, and it did not expressly demand compensation. But the six prior informal change requests and the owner’s “sort out the paper later” direction create a real waiver/estoppel argument. Assert it in writing, preserve the evidence, and do not admit that the claim was late.

6. **Negotiate now, but with arbitration or litigation ready.**  
   If the contract requires arbitration, review the clause immediately and be prepared to file a protective demand if Corestone is not negotiating in good faith. If no arbitration is required, use the lien, cure response, and payment demand to force a settlement or be ready to sue.

# 1. Did the March 3 email satisfy the 14-day notice condition?

## Strict answer: probably not

The subcontract requires:

- written notice;
- within 14 days of the event;
- for any claim for additional time or compensation;
- delivered to the GC’s designated representative;
- and timely written notice is a condition precedent to recovery.

The March 3 email says:

> “FYI hit solid ledge on the south run, this is a big deal, totally different from the geotech.”

Problems:

1. **Wrong recipient.**  
   The email went to Corestone’s superintendent, not Corestone’s designated representative, the project executive.

2. **Not clearly a claim for time or compensation.**  
   It was a field warning, not an express demand for additional time or money.

3. **It only addressed the rock, not the tank.**  
   The tank was discovered March 4. There is no stated contemporaneous notice of the tank.

4. **The formal claim letter was late.**  
   The formal letter went to the project executive on April 5, day 33 from the rock event and day 32 from the tank discovery. The 14-day period had expired long before.

If the notice condition is enforced strictly, the rock and tank claims are in serious trouble.

## But the course of dealing creates a strong waiver argument

The change-order log shows that for the prior year Corestone priced and paid six Stonebriar change requests that were initiated only by field emails to the superintendent, without 14-day formal letters.

That is a powerful waiver fact. It supports the argument that:

- Corestone consistently accepted field emails to the superintendent as effective notice;
- Stonebriar reasonably relied on that practice;
- Corestone waived the formal “letter to the project executive within 14 days” requirement for similar field claims;
- the March 3 email should be treated as sufficient notice of the rock condition and related extra work/delay.

The waiver argument is strongest for the rock claim because the March 3 email directly described the rock ledge and its material difference from the geotech report.

The waiver argument is weaker for the tank claim because the email does not mention the tank. If Stonebriar has any other evidence that Corestone knew of the tank before the 14-day period expired, that must be preserved and used.

## The owner’s “sort out the paper later” direction supports estoppel or waiver

On March 5, the owner’s representative told Stonebriar’s manager in a recorded coordination meeting:

> “Keep your crews working everything you can reach. We will sort out the paper later.”

This statement is important for several reasons:

1. **It came within 14 days of both the rock and tank events.**  
   It occurred after the March 3 rock discovery and the March 4 tank discovery.

2. **It told Stonebriar to continue working while paperwork was deferred.**  
   That is exactly the kind of direction that can induce a subcontractor not to rush formal claim letters.

3. **It supports estoppel.**  
   If Corestone knew of or acquiesced in the owner’s direction, Stonebriar can argue that Corestone may not now enforce the notice condition after telling Stonebriar to “sort out the paper later” while continuing to demand performance.

4. **It may also support active interference or bad faith under the no-damages-for-delay exception.**  
   Telling the subcontractor to keep working, deferring the paper, and then later attacking the delay or payment can be framed as interference with Stonebriar’s claim.

But be careful: the owner is not Corestone. A single owner statement is not automatically a waiver of Corestone’s contractual rights. The strongest argument is that the **course of dealing plus the owner direction plus Corestone’s knowledge/ratification** induced Stonebriar’s reliance.

## Practical position

Stonebriar should not send a letter saying, “This is my first notice.” That would be dangerous.

Instead, send a **supplemental notice of claim** that says, in substance:

- Stonebriar gave contemporaneous field notice on March 3 and March 4;
- Corestone’s course of dealing made field emails sufficient notice;
- the March 5 direction to “sort out the paper later” induced reliance;
- the April 5 letter quantified the claim;
- Stonebriar does not admit that notice was untimely;
- Stonebriar reserves all rights, including waiver, estoppel, and DSC entitlement.

Preserve immediately:

- the March 3 email and metadata;
- any photos attached;
- the March 5 recording;
- the prior six field emails and change orders;
- proof Corestone priced and paid them;
- any evidence the project executive knew of the superintendent email or the March 5 meeting.

# 2. Differing-site-conditions claim: rock and tank

## Rock claim: strong

The geotechnical report in the contract documents showed “medium-dense sands” at utility depth along the south run.

On March 3, Stonebriar hit continuous rock ledge along 240 feet of the south run.

That is a textbook differing-site-condition claim:

- the contract documents indicated one subsurface condition;
- the actual condition was materially different;
- the difference materially affected the work;
- Stonebriar is entitled to an equitable adjustment.

The rock claim should include:

- rock removal or drilling/blasting costs;
- additional excavation equipment;
- additional labor;
- engineering or design review if needed;
- disposal costs;
- direct supervision;
- profit on the extra work;
- extension of time.

## Tank claim: also strong, but notice is riskier

On March 4, Stonebriar uncovered an unmarked buried fuel tank. That triggered a five-week environmental stop in the area.

The DSC clause also covers:

> unknown physical conditions of an unusual nature differing materially from those ordinarily encountered.

An unmarked buried fuel tank at utility depth is a strong DSC fact, especially if:

- it was not shown in contract documents;
- it was not marked;
- it required environmental investigation;
- it required regulatory compliance;
- it forced a stoppage;
- it caused cleanup, testing, or remediation costs.

The tank claim should include:

- tank discovery and response costs;
- environmental investigation;
- regulatory compliance;
- sampling, testing, remediation;
- safety/security measures;
- delay time;
- standby or idle costs, to the extent recoverable;
- acceleration, to the extent recoverable;
- extended overhead, to the extent recoverable.

## What survives the no-damages-for-delay clause?

The no-damages-for-delay clause bars delay damages but does not bar time extensions. It also does not apply to delay caused by the other party’s active interference or bad faith.

So the recovery categories need to be separated.

### A. Direct DSC costs: generally survive

Direct costs caused by the differing condition are not “delay damages.” They are extra work or extra physical response costs.

Likely recoverable:

- rock removal direct costs;
- tank response direct costs;
- environmental compliance direct costs;
- additional labor and equipment to remove the rock;
- costs to deal with the tank and environmental stop.

These should survive the no-damages-for-delay clause, assuming the DSC claim is not barred by the notice condition.

### B. Time extension: survives

The no-damages-for-delay clause does not bar time extensions.

Stonebriar should demand:

- an extension of the project schedule;
- a revised date of substantial completion;
- protection from liquidated damages;
- an acknowledgment that the south-run slippage is excusable.

This is critical because Corestone has issued a default notice for schedule slippage on the south run.

### C. Delay damages: generally barred unless active interference or bad faith is shown

The $918,000 claim includes “tank delay, acceleration, and extended overhead.” Those are delay-damage categories.

They are at risk under the no-damages-for-delay clause.

Likely barred if the delay is ordinary DSC delay:

- extended overhead;
- idle or standby crew;
- general conditions caused by delay;
- self-acceleration;
- schedule extension costs.

### D. Acceleration: recoverable only if supported

Acceleration costs are harder.

They may be recoverable if:

- Corestone or the owner directed acceleration;
- Stonebriar accelerated to recover time lost due to Corestone/owner-caused delay;
- the acceleration was reasonable;
- the delay was on the critical path;
- and the no-damages clause does not bar it because of active interference or bad faith.

If Stonebriar voluntarily accelerated without direction, recovery is weaker.

### E. Extended overhead: recoverable only if the exception applies

Extended overhead is classic delay damages. It is usually barred by a no-damages-for-delay clause unless the delay was caused by active interference or bad faith.

Stonebriar has some facts to support the exception:

- the owner told Stonebriar to keep working and “sort out the paper later”;
- the south run was suspended;
- Corestone withheld undisputed base-scope payment;
- Corestone issued a default notice for slippage caused by the rock, tank, and suspension;
- Corestone may have been in bad faith by using pay-if-paid while not proving owner nonpayment.

But this is a fact-intensive exception. Stonebriar must build the record now:

- daily reports showing requests for work;
- meeting minutes;
- the March 5 recording;
- correspondence about the suspension;
- payment demand letters;
- evidence Corestone knew the slippage was caused by DSC or owner suspension.

## Bottom line on DSC

The entitlement claim is strong. The recovery amount depends on:

1. whether the notice condition is waived or estopped;
2. how much of the claim is direct DSC cost versus delay damages;
3. whether active interference or bad faith can be proven.

Do not assume the entire $918,000 is recoverable. The direct rock and tank response costs are strongest. Time extension is strong. Acceleration and extended overhead are weaker unless the active-interference/bad-faith exception is proven.

# 3. The pay-if-paid withholding of the $410,000

## The clause is enforceable

The subcontract contains a pay-if-paid clause: owner payment is a condition precedent to Corestone’s obligation to pay Stonebriar.

The governing law says such clauses are enforceable according to their terms.

So Corestone may have a valid defense if:

- the $410,000 is otherwise a contract payment;
- the owner has not paid;
- Corestone did not cause the owner’s nonpayment;
- Corestone timely and properly submitted Stonebriar’s applications; and
- the owner’s nonpayment is not the result of Corestone’s default or bad faith.

## But pay-if-paid does not make Corestone’s withholding unlimited

Pay-if-paid lawfully covers only what the clause covers.

It does **not** allow Corestone to:

- ignore the clause’s conditions;
- withhold without proof of owner nonpayment;
- use the clause if Corestone failed to submit applications;
- use the clause if Corestone caused the owner’s nonpayment;
- use the clause if the owner actually paid Corestone;
- use the clause to bar Stonebriar’s lien rights;
- use the clause to avoid interest on amounts that are actually wrongfully withheld.

## Stonebriar’s counters

Stonebriar should demand, in writing:

1. **Proof Stonebriar’s last two applications were submitted to the owner.**
2. **Proof the owner received them.**
3. **Proof of the owner’s payment status.**
4. **The owner’s approval, denial, or nonpayment letter.**
5. **Proof Corestone did not cause or contribute to the nonpayment.**
6. **Immediate payment if the owner has paid Corestone.**
7. **Immediate payment if Corestone failed to submit or process the applications.**
8. **Prompt-payment interest if the $410,000 has been wrongfully withheld.**

## Prompt-payment interest

Statutory prompt-payment interest accrues on amounts wrongfully withheld.

If Corestone’s pay-if-paid defense is valid, the $410,000 is not “wrongfully withheld” yet. But Stonebriar should still demand interest to preserve the claim.

Interest may be recoverable if:

- the owner paid Corestone and Corestone did not pay Stonebriar;
- Corestone failed to submit the applications;
- Corestone caused the owner’s delay;
- Corestone’s assertion of pay-if-paid is bad faith;
- or the amount was otherwise due and wrongfully withheld.

The demand should say:

> “Please identify the exact owner-payment condition, provide proof of submission and owner status, and state why Stonebriar is not entitled to prompt-payment interest from the due date of each application.”

## Pay-if-paid does not stop the lien

Even if Corestone is not yet obligated to pay Stonebriar under the pay-if-paid clause, Stonebriar can still record a lien for unpaid contract balances, subject to the lien’s own requirements.

The pay-if-paid clause affects Corestone’s payment obligation. It does not erase Stonebriar’s lien right for amounts properly due.

---

# 4. The lien: deadline math, safe amount, and conflicts

## Exact deadline math

The lien must be recorded within 90 days after Stonebriar’s last furnishing of labor or materials.

Facts:

- Stonebriar’s last day of work on site was 71 days ago.
- The lien deadline is 19 days away.

The math is:

> 90 days − 71 days = 19 days.

So the outside date is **19 days from today**.

If the last furnishing date was, for example, March 3, then the 90th day is 19 days from today on the stated timeline. But do not rely on inference. Use the actual last furnishing date. If there is any ambiguity in counting, file **before** the computed deadline. The deadline is jurisdictional. There is no equitable tolling.

Also verify:

- the actual last date any labor, material, equipment, or service was furnished;
- whether any warranty crew furnished anything after the 71-days-ago date;
- whether any materials were delivered later;
- whether any temporary power, storage, or other furnishing occurred later.

If any work or materials were furnished later, the clock may be different. But on the facts as stated, treat the lien deadline as 19 days away.

## Safe lien amount

The lien may include:

- unpaid contract balances;
- approved changes.

It may not safely include amounts Stonebriar knows are overstated.

The full $1,328,000 is:

- $410,000 last two applications for undisputed base-scope work;
- $918,000 unapproved DSC/delay claim.

The $918,000 is not an approved change. It includes categories that may be barred by the no-damages-for-delay clause. It has not been adjudicated. It has not been approved by Corestone.

Recording a lien for the full $1,328,000 would risk knowingly overstating the lien amount. That exposes Stonebriar to forfeiture and fees.

### Safe amount

Assuming the $410,000 applications are properly earned, submitted, and undisputed, the safe lien amount is:

> **$410,000**, plus any approved changes or undisputed amounts actually due.

Do not include:

- the unapproved $918,000 claim;
- speculative acceleration;
- speculative extended overhead;
- delay damages not yet approved or adjudicated;
- interest unless the lien statute clearly permits interest and the interest amount is documented and not overstated.

If Corestone later approves a change before the lien deadline, Stonebriar may include that approved amount. But do not include the whole $918,000 claim merely because Stonebriar believes it is ultimately due.

## Does recording the lien now conflict with anything else?

No.

Recording a proper lien is not inconsistent with:

- responding to the cure notice;
- continuing performance;
- negotiating;
- pursuing the DSC claim;
- demanding payment.

In fact, recording the lien early is one of the best leverage tools Stonebriar has.

The conflict arises only if Stonebriar uses the lien threat as an excuse to stop work. That would be dangerous.

The lien should pressure Corestone and the owner. The work stoppage should not.

---

# 5. The seven-day cure notice and the risk of the crew pullout

## Is Corestone’s notice adequate?

Corestone issued a written notice of default citing schedule slippage on the south run and giving seven days to cure.

A default termination requires:

- written notice;
- specifying the default;
- and a seven-day opportunity to cure.

The notice may be adequate on its face if it identifies the default as south-run schedule slippage and gives seven days. But it may be vulnerable if it does not:

- identify the contractual schedule milestone;
- quantify the slippage;
- state what performance is required to cure;
- specify the work area with enough detail;
- or give a realistic cure opportunity given the owner suspension and DSC.

Stonebriar should not gamble on the notice being defective. Treat it as valid and respond immediately.

## What is an adequate cure response?

The cure response should be written, sent to the project executive, copied to the superintendent and owner if appropriate, and delivered within the cure period. It should include:

1. **No admission of default.**
   > “Stonebriar does not admit that it is in default.”

2. **Identification of the cause.**
   > “The south-run slippage is caused by differing site conditions, including the continuous rock ledge and unmarked buried fuel tank, and by owner/GC-caused stoppage. These are excusable causes.”

3. **Preservation of the DSC claim.**
   > “Stonebriar’s March 3 field notice and the March 5 direction to continue work and ‘sort out the paper later’ support waiver/estoppel. Stonebriar reserves all rights under the DSC clause.”

4. **A recovery schedule.**
   Attach a detailed recovery plan showing:

   - current status;
   - critical path;
   - impact of rock and tank;
   - daily production rates;
   - proposed remobilization;
   - additional labor/equipment if needed;
   - sequence of work;
   - look-ahead schedule;
   - milestones.

5. **Commitment to perform.**
   > “Stonebriar will continue performance to the extent safe, authorized, and possible.”

6. **Demand for release/authorization.**
   > “Stonebriar requests written authorization to resume south-run work, release of any suspension, access to the work, and funding of undisputed amounts.”

7. **Demand for payment.**
   > “Stonebriar demands payment of the $410,000 and proof of owner payment status.”

8. **Reservation of rights.**
   > “Stonebriar reserves all rights and remedies, including DSC, time extension, interest, and claims for wrongful suspension or wrongful default.”

9. **Notice if cure is prevented.**
   If Corestone or the owner prevents cure, Stonebriar should say:
   > “If Stonebriar is unable to cure because of access, authorization, funding, or suspension by Corestone or the owner, Corestone is on notice that such failure is not Stonebriar’s default.”

## The owner’s proposed crew pullout is a trap

The plan to pull the remaining warranty crew and “let them sweat” is dangerous.

Under the continue-performance rule:

- a contractor directed to continue during a dispute must comply;
- it must preserve its claims;
- wrongful suspension of work is a default.

If Stonebriar pulls its warranty crew to pressure Corestone, Corestone can say:

- Stonebriar stopped work;
- Stonebriar was in default;
- Stonebriar’s schedule slippage is self-inflicted;
- Stonebriar’s DSC and delay claims are weakened;
- Corestone may terminate;
- Corestone may rehire the work and claim damages.

That would convert Stonebriar from a party with strong DSC and payment claims into the defaulting party.

### What Stonebriar should do instead

- keep the crew working if there is reachable, safe, authorized work;
- if work is unavailable, document that Stonebriar is ready, willing, and able;
- demand work authorization in writing;
- log every day where work was requested but not provided;
- do not treat nonpayment as a self-help stoppage right unless the subcontract expressly provides one and the required notice is given.

If the project owner suspended the south run, Stonebriar should document that the suspension was owner/GC-caused, not a voluntary abandonment by Stonebriar.

---

# 6. Day-by-day sequencing for the next 19 days

To make the calendar clear:

- **Day 1 = tomorrow.**
- **The lien outside date is Day 19**, which is 19 days from today.
- Corestone’s default notice was issued yesterday. The 7-day cure period ends on **Day 6** of this table, but Stonebriar should deliver the cure response on **Day 1** and not wait.

## Day 0 — Today, immediately

1. **Do not pull the warranty crew.**  
   Instruct all field personnel to continue working all reachable, safe, authorized work.

2. **Confirm the last furnishing date.**  
   Verify that 71 days ago is truly the last day labor or materials were furnished. If not, recompute.

3. **Preserve evidence.**  
   Collect and preserve:

   - March 3 email and photos;
   - March 5 recording;
   - prior six field emails and change orders;
   - geotech report;
   - rock/tank discovery documents;
   - environmental stop documents;
   - daily reports;
   - schedule;
   - cost records;
   - payment applications;
   - Corestone payment correspondence;
   - the default notice.

4. **Review the dispute-resolution clause.**  
   Determine whether arbitration is required and what notice period applies.

5. **Prepare the lien.**  
   Prepare a lien for the safe amount: $410,000, plus any approved/undisputed amounts. Do not prepare it for $1,328,000.

6. **Prepare the cure response.**  
   Draft a no-admission cure response with recovery schedule.

7. **Prepare the payment demand.**  
   Demand $410,000 and proof of owner payment status.

8. **Prepare the supplemental DSC notice.**  
   Assert waiver/estoppel and preserve the DSC claim.

## Day 1 — Tomorrow

1. **Record the lien.**  
   File the lien in the proper office before noon if possible. Include:

   - correct legal description;
   - claimant information;
   - last furnishing date;
   - safe lien amount;
   - statement of work;
   - no overstated DSC claim.

2. **Send the cure response.**  
   Deliver to Corestone’s project executive. Copy the superintendent and owner if appropriate. Include the recovery schedule.

3. **Send the payment demand.**  
   Demand the $410,000 and require proof that:

   - applications were submitted;
   - owner has not paid;
   - Corestone did not cause nonpayment;
   - interest is not owed.

4. **Send the supplemental DSC notice.**  
   State that the March 3 email and course of dealing constitute effective notice. Do not admit late notice.

5. **Continue performance.**  
   Return or maintain crews on all reachable work. Daily logs should reflect production and any inability to work due to GC/owner.

## Day 2

1. **Confirm the lien is docketed.**  
   Get the recording reference, stamp, or e-filing confirmation.

2. **Request a meeting.**  
   Ask Corestone’s project executive, superintendent, and owner representative to meet on:

   - default cure;
   - south-run release;
   - payment of $410,000;
   - DSC claim;
   - schedule extension.

3. **Continue work and document.**  
   Photograph rock/tank areas, record production, and note any refusal to provide work or funding.

4. **Follow up on payment demand.**  
   If Corestone has not responded, send a short follow-up demanding proof of owner status.

## Day 3

1. **Hold the meeting if Corestone agrees.**  
   If not, send a letter stating Corestone’s failure to meet and Stonebriar’s continued readiness to perform.

2. **Submit the full DSC claim package if not already sent.**  
   Include:

   - geotech report excerpts;
   - rock photos;
   - tank discovery records;
   - environmental stop documentation;
   - schedule impact;
   - direct cost breakdown;
   - time impact;
   - delay-damage categories separately;
   - evidence of waiver/estoppel.

3. **Demand proof of application submission.**  
   Require copies of Corestone’s submission to the owner and the owner’s response.

4. **If work is being prevented, send a stoppage notice.**  
   State that any stoppage is caused by Corestone/owner, not Stonebriar.

## Day 4

1. **Assert the waiver/estoppel argument in writing.**  
   If Corestone says the notice was late, respond with:

   - the six prior field-email change orders;
   - Corestone’s pricing and payment of them;
   - the March 5 “sort out the paper later” direction;
   - Stonebriar’s reliance;
   - the March 3 email;
   - any evidence the project executive knew.

2. **Update the recovery schedule.**  
   Show actual progress to the extent possible.

3. **Separate direct costs from delay damages.**  
   This is important for the no-damages-for-delay analysis.

4. **If Corestone is not funding or releasing work, escalate in writing.**  
   State that Stonebriar cannot cure if prevented by Corestone/owner.

## Day 5

1. **Finalize cure evidence.**  
   Ensure the cure response and recovery plan are complete.

2. **Send a pre-dispute payment demand.**  
   State that if the $410,000 is not paid or if Corestone cannot prove lawful pay-if-paid status, Stonebriar will pursue interest, lien enforcement, and dispute resolution.

3. **Do not stop work.**  
   Even if frustrated, do not pull the crew.

## Day 6 — Cure deadline

1. **Treat this as the outside cure date.**  
   If the 7-day period ends on this day, Stonebriar must have delivered the cure response and shown reasonable progress.

2. **If Corestone prevents cure, send a final notice.**  
   State that Stonebriar was ready, willing, and able, but cure was prevented by Corestone/owner.

3. **If Corestone threatens termination, respond immediately.**  
   State that the slippage is excusable and that termination would be wrongful.

4. **If Corestone has not terminated, continue performance.**  
   The cure period ending does not mean the dispute is over.

## Day 7

1. **If Corestone terminates, respond in writing immediately.**  
   State that termination is wrongful, that the default notice was based on excusable delay, and that Stonebriar preserves all claims.

2. **If Corestone does not terminate, continue performance and negotiation.**

3. **Decide whether to file a protective arbitration demand or suit.**  
   If Corestone is not negotiating in good faith and the contract requires arbitration, consider filing a protective demand now. If no arbitration is required, be ready to file suit after a short final demand.

## Day 8–10

1. **If unresolved, escalate.**  
   Send a final demand letter stating:

   - $410,000 is due;
   - interest is due if wrongfully withheld;
   - DSC claim is preserved;
   - default notice is wrongful;
   - Stonebriar will pursue arbitration/suit if not resolved.

2. **If arbitration is required, file the demand.**  
   Do not let negotiation delay a mandatory filing.

3. **If no arbitration is required, consider filing suit** after the demand period expires, especially if Corestone continues to withhold undisputed amounts.

4. **Continue performance.**  
   Unless Stonebriar is validly terminated, do not stop.

## Day 11–14

1. **Use the lien as settlement leverage.**  
   A valid lien pressures the owner and Corestone. It may produce payment or a bond.

2. **Push for a DSC resolution.**  
   The goal is a change order, settlement, or arbitration claim with a strong record.

3. **Continue documentation.**  
   Every day of continued nonpayment or prevented work strengthens the record.

4. **If Corestone pays the $410,000, release the lien.**  
   If not, prepare to enforce it.

## Day 15–18

1. **If arbitration or suit is filed, proceed.**  
   Use the lien, cure response, and payment demand as part of the dispute record.

2. **If negotiating, do not stop work.**  
   The crew should continue performing or be documented as prevented.

3. **If Corestone approves any change before the lien deadline, evaluate whether the approved amount can be added to the lien.**  
   Only if the amount is approved and not overstated.

## Day 19 — Lien outside date

1. **If the lien has already been recorded, confirm it is docketed and monitor for bond or payment.**

2. **If somehow the lien has not been recorded, record the safe amount immediately.**  
   But this should not happen. The lien should have been recorded on Day 1.

3. **Do not miss this date.**  
   The lien deadline is jurisdictional. If it passes, Stonebriar loses the lien for the pre-deadline work.

---

# 7. Litigate, arbitrate, or negotiate?

## First: check whether arbitration is mandatory

If the subcontract requires arbitration, Stonebriar should not litigate in court. It must arbitrate, subject to any applicable notice period.

If arbitration is required, Stonebriar should:

- review the clause immediately;
- identify any demand deadline;
- file a protective demand if Corestone is not negotiating in good faith;
- continue performance and preserve the lien in the meantime.

Arbitration can be faster and private, but it also may have limited appeal and strict procedural deadlines.

## If no arbitration is required: negotiate first, but be ready to sue

Stonebriar has strong leverage:

- a valid lien;
- a timely cure response;
- strong DSC facts;
- Corestone’s need to document owner payment;
- prompt-payment interest if the withholding is wrongful;
- a potential counterclaim for wrongful default or wrongful suspension.

A good settlement target is:

- Corestone pays the $410,000;
- Corestone pays interest if applicable;
- Corestone withdraws the default notice;
- Corestone grants a schedule extension;
- Corestone agrees to process the DSC claim promptly or submits it to arbitration;
- Stonebriar releases the lien after payment.

But negotiation should not be the only strategy. If Corestone continues to withhold undisputed payment or ignores the DSC claim, Stonebriar should be ready to file.

## Leverage each deadline creates

### Lien deadline

A properly recorded lien is powerful. It clouds the owner’s property, pressures the owner to pay or bond, and may force Corestone to resolve the payment issue.

But the lien is only as good as its accuracy. An overstated lien destroys the leverage and creates fee/forfeiture risk.

### Cure deadline

The cure response prevents Corestone from terminating. If Stonebriar misses it, Corestone may terminate and Stonebriar becomes the defaulter.

If Corestone prevents cure, the cure record becomes evidence of Corestone’s bad faith or active interference.

### Notice condition

The 14-day notice period is already a problem. The waiver/estoppel argument must be asserted now. If Stonebriar waits too long, Corestone may harden its position and Stonebriar may lose the DSC claim despite strong facts.

### Pay-if-paid deadline

Every day Corestone withholds the $410,000 without proof of owner nonpayment increases pressure. If the withholding is wrongful, interest accrues. If Corestone cannot prove the pay-if-paid condition, its defense collapses.

### DSC claim

The rock and tank facts are strong, but the claim is only valuable if Stonebriar can preserve it and prove the cost/schedule impact. The longer the dispute drags, the more important the documentation becomes.

# 8. The single most costly mistake available to the client this week

The single most costly mistake is:

> **Pulling the remaining warranty crew and stopping performance to pressure Corestone.**

That mistake would turn Stonebriar into the defaulting party. It would give Corestone a termination basis, weaken the DSC claim, support Corestone’s default notice, and undermine Stonebriar’s position on delay, acceleration, and extended overhead.

The lien should do the sweating. The cure response should do the protection. The payment demand should do the collection pressure.

The close second most costly mistake is recording the lien for the full **$1,328,000** instead of the safe, supportable amount. That risks forfeiture and fees.
