**Bottom line: Do not pull the remaining crew. Do not file a $1,328,000 lien. Continue work, answer the default notice, preserve the claims, and record a lien for the safe $410,000 before the 19-day jurisdictional deadline.**

## 1. The March 3 email: notice condition, waiver, and estoppel

Strictly applied, the March 3 email did **not** satisfy the subcontract’s notice condition:

- It was written and timely.
- But it was sent to **Corestone’s superintendent**, not to the designated **project executive**.
- The formal claim letter sent on April 5 (day 33) was **late** under the 14-day clause.

So Stonebriar must argue waiver/estoppel.

**Stonebriar has a strong waiver/estoppel argument** based on Corestone’s course of dealing:

- Corestone had accepted and paid **six prior change requests** initiated only by field emails to the superintendent.
- Stonebriar reasonably used the same accepted channel.
- Corestone never insisted on the 14-day formal letter for those claims.
- Under the governing rule, a party may waive a notice condition through a consistent course of dealing that induces reliance.

The owner representative’s statement — *“Keep your crews working everything you can reach. We will sort out the paper later”* — is weaker because the owner representative is not Corestone’s designated representative. But it is still valuable:

- It supports Stonebriar’s claim that Stonebriar was told to keep working and that paperwork would be handled later.
- It supports equitable estoppel against strict enforcement.
- It may bind Corestone if Corestone allowed the owner to direct Stonebriar’s work or later ratified that direction.

**Action:** Do not rely on the March 3 email alone. Send an immediate confirming notice to Corestone’s project executive by email and overnight mail, stating:

- this confirms the March 3 notice;
- Corestone waived the notice requirement through its course of dealing;
- the owner rep directed Stonebriar to continue and said paperwork would be resolved later;
- Stonebriar reserves all rights;
- details of the rock, tank, suspension, and cost impact are being provided under reservation.

## 2. Differing site conditions and the no-damages-for-delay clause

### Rock ledge and buried tank are differing site conditions.

- The geotechnical report showed **medium-dense sands**.
- Stonebriar instead encountered **continuous rock ledge** along 240 feet.
- Stonebriar then uncovered an **unmarked buried fuel tank**, which is an unknown physical condition of an unusual nature.

So the differing-site-conditions clause likely applies to **both the rock and the tank**.

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

Stonebriar is **not automatically barred from all recovery**.

Survives:

- **Time extensions** for the rock and tank delays. The no-damages clause does not bar time extensions.
- **Equitable adjustment for the changed-condition work itself**, including reasonable costs attributable to rock removal and tank abatement/direct response costs, if proven.
- **Reasonable direct field costs** caused by the changed condition, as part of the DSC adjustment.
- **Acceleration costs** only if Stonebriar can show Corestone or the owner directed acceleration, or refused to grant a time extension while demanding original completion. A voluntary acceleration is not recoverable.
- **Delay damages** only if Stonebriar can prove active interference or bad faith by Corestone/owner.

Likely barred unless active interference is proven:

- **Extended overhead** based on delay.
- **Unabsorbed home-office overhead**.
- **Idled equipment and crew for the five-week stop** if treated as delay damages.
- **Loss of productivity/profit caused by delay**.
- **Pure delay costs** for the tank/environmental stop.

The active-interference exception matters here, but the facts do not yet prove it. A buried tank is not itself active interference. If Stonebriar can show Corestone or the owner:

- knew about the tank or ledge and concealed it;
- suspended the south run in bad faith;
- refused to grant time while threatening default; or
- otherwise prevented Stonebriar from working,

then delay damages may survive the no-damages-for-delay clause.

**Action:** Separate the $918,000 claim into categories:

- rock removal/direct changed-condition costs;
- tank/direct abatement costs;
- time extension;
- acceleration costs, if directed;
- delay damages, which are at risk.

Do not present the whole $918,000 as a single lienable, recoverable amount.

## 3. Pay-if-paid and the $410,000 unpaid base-scope work

The pay-if-paid clause is enforceable according to its terms. If the owner has not paid Corestone for Stonebriar’s work, Corestone may not yet be required to pay Stonebriar.

But the clause is not a blank check.

Corestone can lawfully withhold **only if**:

- the owner has actually not funded the specific applications;
- Corestone is not the reason the owner failed to pay;
- Corestone has not already received payment for that work; and
- Corestone is otherwise acting in good faith.

Stonebriar’s counters:

1. **Demand proof of nonpayment.** Require Corestone to identify each application, the amount submitted to the owner, the amount funded, and the amount not funded.
2. **Demand prompt payment if Corestone has been paid.** If the owner funded the applications but Corestone did not pass the money to Stonebriar, the pay-if-paid condition has occurred, and the withholding is wrongful.
3. **Preserve statutory prompt-payment interest.** Interest accrues on amounts **wrongfully withheld**. If Corestone was paid and refused to pay Stonebriar, interest should run from the date payment was due.
4. **Do not stop work.** The pay-if-paid clause does not justify self-help suspension unless the contract or statute clearly allows it.
5. **Use the mechanics lien to protect the $410,000.** The lien is a separate remedy against the property and should be preserved regardless of the pay-if-paid dispute.

---

## 4. Mechanics lien: deadline, amount, and conflicts

### Deadline math

Stonebriar last furnished labor or materials **71 days ago**.

The lien must be recorded within **90 days after last furnishing**.

So:

> **90 – 71 = 19 days remaining.**

The last day to record is **Day 19 from today**. Because the deadline is jurisdictional, Stonebriar should treat **Day 14 as its internal deadline**, not Day 19.

Do not rely on Day 19 if it is a weekend, holiday, or if the recording office has issues.

### Safe lien amount

Under the stated rule, a lien may include **unpaid contract balances** and **approved changes**.

The only amount that is clearly safe on these facts is:

> **$410,000** for the undisputed, unpaid base-scope work.

Stonebriar should **not** include the $918,000 claim at this point because:

- it is not an “approved change”;
- it is disputed;
- it includes delay damages, acceleration, and extended overhead that may be barred by the no-damages-for-delay clause;
- recording a lien for amounts that are not lienable or are knowingly overstated can result in **forfeiture of the lien and fees**.

If Corestone approves any change order before recording, Stonebriar may add that approved amount. But as of today:

> **Do not record a lien for $1,328,000. Record only $410,000.**

### Does recording now conflict with anything else?

No, provided Stonebriar **continues working** and does not use the lien as a threat to abandon the project.

A properly limited lien does not conflict with:

- responding to the default notice;
- continuing performance;
- pursuing the DSC claim; or
- demanding payment.

It **does** conflict with the “let them sweat” plan if Stonebriar also pulls the crew and stops work. That combination would look like retaliation and abandonment.

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

Corestone issued a written default notice **yesterday**. Stonebriar cannot ignore it.

Stonebriar must, within the cure period:

1. **Respond in writing** to Corestone’s project executive.
2. **Deny the default** or show excused delay:
   - the south run was suspended;
   - rock and tank were differing site conditions;
   - Stonebriar is entitled to a time extension;
   - any schedule slippage is not Stonebriar’s fault.
3. **State that Stonebriar is ready, willing, and able to perform** all work that can be reached.
4. **Demand access and direction** if Stonebriar cannot work because of the suspension.
5. **Submit a cure/remobilization plan** if any actual curable default exists.
6. **Reserve all rights** under the subcontract and law.

An adequate cure response is not just a letter. If there is work Stonebriar can lawfully perform, Stonebriar should **actually resume it**.

### The crew-pullout is the biggest immediate risk

Stonebriar’s owner wants to pull the remaining warranty crew. That is a serious mistake.

Under the stated rule:

> A contractor directed to continue performance during a dispute must comply and preserve its claims, and wrongful suspension of work is a default.

If Stonebriar pulls the remaining crew while the default notice is pending, Stonebriar:

- becomes the defaulting party;
- gives Corestone grounds for termination;
- loses the moral and legal position on the DSC claim;
- may forfeit the opportunity to cure;
- exposes Stonebriar to reprocurement damages and delay claims.

Pulling the crew is not leverage. It is self-help default.

---

## 6. Sequencing: next 19 days

Use “Day 0” as today. Day 19 is the last day to record the lien.

### Day 1 — emergency actions

Send all of the following to Corestone’s **project executive**:

- response to the default notice;
- reservation-of-rights and confirming notice of claim;
- demand for time extension based on rock and tank;
- payment demand for the $410,000 and proof of owner nonpayment;
- demand for access/direction if Stonebriar is being kept from work.

Also:

- Do **not** pull the crew.
- If any work is available, continue performing it.
- Contact counsel and gather the contract, geotech report, emails, field logs, and cost records.

### Day 2 — verify the lien facts

- Confirm the exact date of last furnishing.
- Confirm the $410,000 figure and the unpaid applications.
- Confirm whether there are any approved but unpaid change orders.
- Confirm whether Corestone has actually been paid by the owner.

### Day 3 — payment demand and pre-lien notice

Send a clear pre-lien demand to Corestone and the owner:

- Stonebriar is owed $410,000 for undisputed work;
- unless paid, bonded, or secured, Stonebriar will record a mechanics lien;
- the lien must be recorded by Day 19.

Prepare the verified lien claim for **$410,000 only**.

### Days 4–7 — record the lien or obtain security

If Corestone and the owner have not paid or posted acceptable security by Days 4–7, **record the $410,000 lien**.

Do not wait until Day 19.

Recording a $410,000 lien while continuing work:

- preserves Stonebriar’s lien rights;
- creates settlement pressure;
- does not itself breach the subcontract;
- forces the owner/Corestone to deal with the lien.

### Days 8–14 — negotiate or begin dispute process

- Continue performance.
- Push for a global resolution:
  - Corestone grants time extension;
  - Corestone/owner pays the $410,000;
  - Corestone approves a change order for the rock/tank direct costs;
  - Stonebriar releases the lien;
  - both sides exchange mutual releases of the default notice.
- If negotiation fails and the contract requires arbitration, **serve a demand for arbitration**.
- If the contract does not require arbitration, prepare litigation.
- Do not let the lien deadline pass.

### Days 15–18 — final lien check

If for any reason the lien has not been recorded, record it now.

By Day 18 at the latest, the lien should already be on file.

### Day 19 — absolute deadline

If not recorded, record the lien **before the recording office closes**.

This is the jurisdictional deadline. No extensions, no “close enough,” no reliance on next-day filing.

## 7. Litigation, arbitration, or negotiation?

**Negotiate first, but negotiate from a position of performance and protected lien rights.**

Each deadline creates leverage:

- **Corestone’s seven-day default notice** gives Corestone short-term leverage, but Stonebriar can neutralize it by responding and continuing performance.
- **Stonebriar’s 19-day lien deadline** gives Stonebriar leverage over the owner and Corestone, because a $410,000 lien on the property is a title problem.
- **The notice condition dispute** is a litigation risk for both sides: Corestone can argue late notice; Stonebriar can argue waiver/estoppel.
- **The no-damages-for-delay clause** limits Stonebriar’s recovery, but the DSC clause and time extension protect Stonebriar from default.
- **The pay-if-paid clause** helps Corestone, but only if the owner truly has not funded the work.

Best strategy:

1. Continue work.
2. Answer the default.
3. File the $410,000 lien if not paid.
4. Then negotiate a global deal.

If the contract requires arbitration, Stonebriar must arbitrate the contract claims unless the lien foreclosure must be filed in court. Do not let a negotiation delay cause a missed arbitration deadline.

---

## 8. The single most costly mistake available this week

> **Stopping work — pulling the remaining crew off the project.**

That is the one move that turns Stonebriar from the injured claimant into the defaulting party. It forfeits the cure opportunity, gives Corestone a termination basis, exposes Stonebriar to reprocurement damages, and undermines every claim Stonebriar has.

The second most costly mistake is filing a lien for **$1,328,000**.

Stonebriar should instead:

- **keep working;**
- **answer the default;**
- **record a $410,000 lien;**
- **preserve the $918,000 claim through arbitration/negotiation;**
- **use the deadlines to force a settlement.**

Do not let them sweat. Make them pay.
