## SECTION 1: CHANGE ORDER FUNDAMENTALS

### What Is a Change Order

A change order (CO) is a formal written amendment to a construction contract that modifies the original scope of work, contract price, contract time, or any combination of these. Once signed by all parties, the change order becomes part of the contract with the same legal force as the original agreement.

```
CHANGE ORDER = FORMAL CONTRACT AMENDMENT

It modifies one or more of:
1. SCOPE   — What work is included
2. PRICE   — What the project costs
3. TIME    — When the project finishes
4. TERMS   — Conditions of the work

A change order is NOT:
- A verbal agreement ("can you also do this while you're here?")
- An email request without formal acceptance
- A punch list item that should have been in the original scope
- A correction of defective work by the contractor
```

### Why Change Orders Exist

Change orders serve critical functions in construction:

1. **Legal protection.** They create a documented paper trail of what changed, why, who approved it, and what it costs. Without this documentation, contractors absorb extra costs.
2. **Fair compensation.** When the scope grows, the price and schedule should adjust accordingly. Change orders enforce this principle.
3. **Dispute prevention.** Most construction disputes involve one party saying "that was included" and the other saying "that was extra." Change orders eliminate ambiguity.
4. **Project control.** They force all parties to stop, evaluate, and formally agree before proceeding with changed work. This prevents runaway costs and schedules.
5. **Financial records.** They create auditable records for accounting, tax purposes, bonding companies, and lenders.

### Legal Implications

Change orders carry real legal weight:

- **Contract modification.** A signed change order amends the contract. Both parties are bound by the new terms.
- **Waiver risk.** Performing changed work WITHOUT a change order may be treated as voluntary — meaning you cannot collect for it later.
- **Lien rights.** In many states, work performed under a change order is lienable, but ONLY if the change order is properly documented and signed. Verbal extras may not be recoverable.
- **Statute of frauds.** Many states require contract modifications over a certain dollar amount to be in writing. Verbal change orders above that threshold may be unenforceable.
- **Notice requirements.** Many contracts require the contractor to provide written notice of a change within a specific timeframe (often 7-14 days). Miss the window and you may waive your right to claim extra compensation.
- **Payment bond claims.** On bonded projects, change order work must be properly documented to make a valid payment bond claim.

### When a Change Order Is REQUIRED

A change order is mandatory when any of the following occurs:

| Trigger | Example |
|---------|---------|
| Owner requests additional work | "Add a bathroom to the basement" |
| Owner requests deletion of work | "Skip the crown molding" |
| Design error or omission discovered | Plans show 100A panel but loads require 200A |
| Unforeseen site condition found | Rotten subfloor under tile, asbestos, rock |
| Code requirement not in original scope | Inspector requires fire-rated assembly |
| Material substitution with cost difference | Specified material discontinued, replacement costs more |
| Schedule acceleration requested | "We need this done 2 weeks earlier" |
| Force majeure / regulatory change | New code adopted mid-project |
| Access conditions change | Blocked access adds mobilization cost |
| Errors in owner-furnished information | Survey was wrong, dimensions do not match |

### When a Change Order Is NOT Needed

- Punch list corrections of work within the original scope
- Contractor fixing their own defective work
- Normal coordination between trades
- Minor material substitutions at same cost and quality with owner verbal OK (but still document it)
- Work explicitly included in the allowance

---

## SECTION 2: CHANGE ORDER TYPES

### Type 1: Additive Change Order (Most Common)

Adds scope, increases cost, may extend time.

```
ADDITIVE CHANGE ORDER

When to use:
- Owner requests additional work beyond original scope
- Unforeseen condition requires additional work
- Code change mandates additional work

Impact:
- Contract price INCREASES
- Contract time may INCREASE
- Scope EXPANDS

Example:
Original scope: Remodel kitchen, existing subfloor in good condition
Change: Discovered rotted subfloor joists — add structural repair
Cost impact: +$3,200
Time impact: +3 working days
```

### Type 2: Deductive Change Order (Credit)

Removes scope, decreases cost, may reduce time.

```
DEDUCTIVE CHANGE ORDER

When to use:
- Owner decides to eliminate part of the scope
- Design simplification reduces work
- Owner will self-perform some work (e.g., painting)

Impact:
- Contract price DECREASES
- Contract time may DECREASE
- Scope SHRINKS

Example:
Original scope: Full kitchen remodel including backsplash tile
Change: Owner will hire own tile contractor for backsplash
Cost impact: -$2,800
Time impact: No change (tile was not on critical path)

IMPORTANT:
Deductive change orders should reflect the contractor's actual cost savings,
NOT the full retail value of the deleted work. The contractor retains overhead
and profit on the deleted scope because the project was priced as a whole.
Typical deductive credit = direct cost only (labor + materials), NOT including
overhead and profit.
```

### Type 3: No-Cost Change Order

Modifies scope or method but does not change the price or time.

```
NO-COST CHANGE ORDER

When to use:
- Material substitution at equivalent cost
- Method change that does not affect price or schedule
- Clarification of scope where both parties agree no cost impact

Impact:
- Contract price UNCHANGED
- Contract time UNCHANGED
- Scope MODIFIED but cost-neutral

Example:
Original scope: Install Kohler K-3609 toilet
Change: Model discontinued — substitute Kohler K-3817 at same cost
Cost impact: $0
Time impact: No change

WHY DOCUMENT IT:
Even at zero cost, you need a paper trail showing what was changed
and that both parties agreed. This prevents disputes at closeout
about what was "supposed to be" installed.
```

### Type 4: Time-Only Change Order

Extends the schedule without changing the cost.

```
TIME-ONLY CHANGE ORDER

When to use:
- Owner-caused delay (late decisions, slow approvals)
- Weather delays beyond contract allowances
- Material delivery delays outside contractor's control
- Permit delays caused by jurisdiction backlog
- Utility company delays

Impact:
- Contract price UNCHANGED
- Contract time INCREASES
- Scope UNCHANGED

Example:
Original completion: March 15, 2026
Change: Owner took 3 weeks to select countertop material (contract allows 5 business days)
Cost impact: $0 (no acceleration costs incurred)
Time impact: +11 working days (new completion: March 30, 2026)

CRITICAL:
Always document time-only changes. If the project runs late and there
is a liquidated damages clause, documented time extensions protect you.
Without them, delays look like YOUR fault.
```

## SECTION 4: PRICING METHODS FOR CHANGE ORDERS

Different pricing methods are appropriate for different situations. The original contract often specifies which method to use.

### Method 1: Lump Sum (Fixed Price)

```
LUMP SUM PRICING

How it works:
Contractor prices the change as a fixed total. Owner agrees to the number.

When to use:
- Scope of change is clearly defined
- Materials and labor can be accurately estimated
- Owner wants price certainty

Advantages:
+ Owner knows exact cost upfront
+ No time tracking required
+ Simpler administration

Disadvantages:
- Contractor bears risk of underestimation
- Must include contingency in price
- Disputes if scope is ambiguous

Typical markup: 15-25% overhead + 10-15% profit on direct costs

Example:
Labor (16 hrs x $52/hr):           $832.00
Materials:                          $486.00
Equipment:                          $180.00
Direct cost subtotal:             $1,498.00
Overhead (20%):                     $299.60
Profit (10%):                       $149.80
LUMP SUM TOTAL:                   $1,947.40
```

### Method 2: Unit Price

```
UNIT PRICE METHOD

How it works:
Contractor provides a per-unit price. Final cost based on actual quantities.

When to use:
- Type of work is known but quantity is uncertain
- Repetitive tasks (outlets, fixtures, linear feet of pipe)
- Owner wants flexibility on quantity

Example:
Additional recessed lights: $180 per light installed
Additional 20A circuits: $350 per circuit
Additional drywall patching: $8.50 per square foot

Advantages:
+ Fair for both parties — pay for what you get
+ No need to precisely estimate quantity upfront
+ Easy to verify and audit

Disadvantages:
- Final cost unknown until work complete
- Need clear measurement/counting method
- Disagreements on quantity measurement possible

Best practice: Define the unit clearly in the change order.
"Per recessed light" means what exactly? Installed, wired,
trimmed, tested? Spell it out.
```

### Method 3: Time and Materials (T&M)

```
TIME AND MATERIALS PRICING

How it works:
Contractor tracks actual labor hours and material costs.
Owner pays actual cost plus agreed markup.

When to use:
- Scope cannot be defined in advance
- Exploratory or diagnostic work
- Emergency repairs
- Small, quick changes not worth formal pricing

Rates:
Labor rate: $XX/hr (includes burden, overhead, profit)
Material markup: XX% over invoice cost
Equipment: Actual rental cost + XX% markup
Subcontractor: Actual cost + XX% markup

Safeguards for both parties:
- Set a not-to-exceed (NTE) amount
- Require daily time and material tickets signed by owner/rep
- Contractor provides receipts for all materials
- Owner can stop work at any point

Example daily ticket:
┌─────────────────────────────────────────┐
│ T&M DAILY TICKET                        │
│ Date: _________ CO #: ________          │
│                                         │
│ Workers:                                │
│ [Name] ______ hrs @ $____/hr = $______  │
│ [Name] ______ hrs @ $____/hr = $______  │
│                                         │
│ Materials purchased today:              │
│ [Item] ______________ Cost: $________   │
│ [Item] ______________ Cost: $________   │
│ Material markup (XX%):       $________  │
│                                         │
│ Equipment:                              │
│ [Item] ______________ Cost: $________   │
│                                         │
│ DAILY TOTAL:                 $________  │
│                                         │
│ Owner/Rep Signature: ________________   │
│ Contractor Signature: _______________   │
└─────────────────────────────────────────┘
```

### Method 4: Cost-Plus (with Fee)

```
COST-PLUS PRICING

How it works:
Owner pays all direct costs (labor at burdened rate, materials at
invoice cost, equipment at rental rate) plus a fixed fee or
percentage for overhead and profit.

When to use:
- Large, complex changes where scope is evolving
- Trust-based relationships
- When the contract specifies cost-plus for changes

Fee structures:
Option A: Fixed percentage (e.g., cost + 15% O&P)
Option B: Fixed fee (e.g., cost + $2,000 flat fee)
Option C: Sliding scale (e.g., 15% on first $10K, 10% on next $20K, 8% above $30K)

AIA standard: 15% overhead + 10% profit on self-performed work
              10% on subcontractor work
ConsensusDocs: Negotiable, but 15% combined is common
```

### Choosing the Right Pricing Method

| Situation | Recommended Method |
|-----------|-------------------|
| Clear scope, defined quantities | Lump sum |
| Known work type, unknown quantity | Unit price |
| Unknown scope, diagnostic work | T&M with NTE |
| Large complex change | Cost-plus with fee |
| Emergency / urgent change | T&M with daily tickets |
| Owner-directed acceleration | T&M for premium-time labor |

---

## SECTION 5: WRITING EFFECTIVE JUSTIFICATIONS

The justification section is the heart of a change order. It must be clear, factual, and referenced to the original contract. Poor justifications lead to disputed or rejected change orders.

### Principles of Strong Justifications

1. **Be factual, not emotional.** "The subfloor was discovered to be structurally compromised" not "The subfloor is a mess."
2. **Reference the contract.** "Per Section 4.3 of the original contract, unforeseen conditions warrant a change order."
3. **Include dates.** "On February 15, 2026, during demolition of the existing tile floor, the crew discovered..."
4. **Reference specific locations.** "In the kitchen area, between the island and the exterior wall, approximately 80 square feet of subfloor..."
5. **Cite the standard or code.** "IRC Section R502.1.1 requires floor joist bearing of minimum 1.5 inches..."
6. **Explain why this was not foreseeable.** "This condition was concealed beneath the existing tile and cement board and could not have been detected during the pre-construction site assessment."
7. **State what happens if the change is not approved.** "Without addressing the structural deficiency, the new tile installation cannot proceed and the completed floor would not meet code requirements."

### Justification Templates by Change Reason

**Owner-Requested Change:**
```
On [date], the owner verbally requested / submitted in writing a
request to [description of change]. This work is outside the scope
of the original contract dated [date], which includes [reference
specific scope section]. The owner's request was confirmed via
[email/letter/meeting notes] dated [date]. A copy of the owner's
request is attached.
```

**Unforeseen Site Condition:**
```
On [date], during [activity — e.g., demolition, excavation, rough-in],
the crew discovered [specific condition — e.g., deteriorated subfloor
joists, abandoned underground tank, asbestos-containing material] at
[specific location]. This condition was not visible during the pre-
construction assessment and was concealed by [what hid it — e.g.,
existing flooring, drywall, soil]. Photographs documenting the condition
were taken on [date] and are attached. [If applicable: A qualified
[engineer/environmental consultant/inspector] evaluated the condition
on [date] — see attached report.] This condition must be addressed
before [next trade/task] can proceed.
```

**Design Error or Omission:**
```
During [phase of work], the contractor identified [a conflict /
an omission / an error] in the construction documents. Specifically,
[description — e.g., the mechanical drawings show ductwork routing
through a structural beam shown on the structural drawings, drawing
M-201 conflicts with S-103]. The contractor submitted RFI #[number]
on [date] requesting clarification. The architect/engineer responded
on [date] directing [the revised approach]. The revised approach
requires additional [work/materials/time] not included in the original
contract scope. A copy of the RFI and response is attached.
```

**Code or Regulatory Requirement:**
```
During the [inspection type] inspection on [date], the building
inspector [name/jurisdiction] directed that [specific requirement —
e.g., a two-hour fire-rated assembly be installed at the garage-
to-living-space separation per [code section]]. This requirement
was not included in the original construction documents. The original
plans called for [what was originally specified]. The additional work
required to meet the inspector's directive includes [scope of
additional work]. A copy of the inspection report/correction notice
is attached.
```

**Material Substitution:**
```
The specified material [product name, model number, spec reference]
is [discontinued / unavailable / on backorder until (date)]. The
contractor has identified [substitute product name/model] as the
nearest equivalent that meets the project specifications. The
substitution results in a [cost increase of $X / cost decrease of
$X / no cost change]. [If applicable: the substitution has been
reviewed and approved by the architect/engineer — see attached
approval.] [If lead time is affected: The substitute material has a
lead time of [X] weeks, which [does/does not] affect the project
schedule.]
```

## SECTION 6: DOCUMENTING UNFORESEEN CONDITIONS

Unforeseen conditions are the most common — and most disputed — reason for change orders. Proper documentation at the moment of discovery is critical.

### Immediate Documentation Protocol

When you discover an unforeseen condition on a job:

```
UNFORESEEN CONDITION DOCUMENTATION CHECKLIST

1. STOP WORK in the affected area immediately
   - Do not disturb or repair the condition
   - Secure the area if it is a safety hazard

2. PHOTOGRAPH EVERYTHING (minimum requirements):
   [ ] Wide shot showing the condition in context (room/area)
   [ ] Medium shot showing the full extent of the condition
   [ ] Close-up shots showing detail/damage
   [ ] Photos with a tape measure or reference object for scale
   [ ] Photos of surrounding areas showing the concealment
       (e.g., what was covering the condition before removal)
   [ ] Timestamp visible in photo metadata or on a date board

3. VIDEO WALKTHROUGH (recommended):
   [ ] 1-2 minute narrated video explaining what was found
   [ ] Walk from normal approach to the condition
   [ ] Show what concealed it
   [ ] Show extent of damage/issue

4. NOTIFY THE OWNER (same day):
   [ ] Phone call to owner and/or owner's representative
   [ ] Follow up with email/text documenting the call:
       "Per our phone conversation today at [time], I am
        notifying you that we have discovered [condition]
        at [location]. Work in this area is paused pending
        your review. We will prepare a change order for the
        additional work required."

5. NOTIFY THE ARCHITECT/ENGINEER (if applicable):
   [ ] Same-day notification per contract requirements
   [ ] Request site visit if needed

6. PRESERVE EVIDENCE:
   [ ] Do not repair or demolish the condition until
       documented and reviewed by all parties
   [ ] If safety requires immediate action, document
       that you took emergency protective measures

7. PREPARE CHANGE ORDER within [contract-required timeframe,
   typically 7-14 days]
```

### Photo Documentation Best Practices

```
PHOTO LOG FOR CHANGE ORDER CO-[XXX]

Photo 1: [Date] [Time] — Overview of [area], showing [description]
Photo 2: [Date] [Time] — Close-up of [specific condition]
Photo 3: [Date] [Time] — Scale reference showing [measurement]
Photo 4: [Date] [Time] — [Area] before demolition of concealment
Photo 5: [Date] [Time] — [Area] after exposure of condition

All photos stored at: [Cloud folder link / file location]
Photos taken by: [Name, title]
```

### Evidence That Strengthens an Unforeseen Condition Claim

| Evidence Type | Why It Matters |
|--------------|---------------|
| Dated photographs with scale reference | Proves condition existed, shows extent |
| Video walkthrough with narration | Harder to dispute than still photos |
| Written owner notification (same day) | Proves timely notice |
| Third-party inspection report | Independent verification |
| Pre-construction photos of same area | Shows condition was concealed |
| Original plans/specs showing assumption | Proves design did not anticipate condition |
| Soil report / environmental test | Scientific evidence for subsurface issues |
| Inspector's correction notice | Government authority confirming the issue |
| Daily log entry noting discovery | Contemporaneous record |
| Witness statement from crew member | Corroborating testimony |

---

## SECTION 7: HANDLING CLIENT PUSHBACK

Clients often resist change orders. This is normal. Here are the most common objections and professional responses.

### Common Objection: "This should have been included in the original price"

```
Response framework:

"I understand your concern. Let me explain what our original
scope covered and why this is additional work.

Our contract dated [date] specifically includes [reference scope].
The work described in this change order — [description] — is
outside that agreed-upon scope because [reason].

[If unforeseen condition]:
This condition was concealed behind [what hid it] and could not
have been detected during our pre-construction walkthrough. You
can see in photos [reference] that the condition was completely
hidden.

[If owner request]:
This is work you have requested in addition to what we originally
agreed to. I am happy to do it — I just need the change order
signed so we are both protected."
```

### Common Objection: "Your price is too high for this change"

```
Response framework:

"I have broken down the cost line by line so you can see exactly
where every dollar goes. [Walk through the cost breakdown.]

The labor hours are based on [trade standard / my experience with
this exact type of work]. The material prices are [from my supplier
quote dated X / current market pricing]. The overhead and profit
percentages are [consistent with our original contract pricing /
industry standard per AIA guidelines].

I am open to discussing ways to reduce the cost if you would like
to consider [alternative approaches, reduced scope, or different
materials]. But I cannot perform the work at a loss."
```

### Common Objection: "Just do it and we'll figure out the cost later"

```
Response framework:

"I appreciate your trust, but I have learned from experience that
'figuring it out later' leads to misunderstandings on both sides.

I would rather take 30 minutes now to document the change properly
so we both know exactly what is being done and what it costs. This
protects both of us.

If this is urgent and you need us to proceed immediately, I can
do the work on a time-and-materials basis with daily sign-off on
hours and costs. That way the work continues and the costs are
documented as we go."
```

### Common Objection: "I'll find someone cheaper to do this part"

```
Response framework:

"You are welcome to get other quotes. A few things to consider:

1. Another contractor coming onto an active job site creates
   coordination issues and liability questions.
2. If their work affects our work and something goes wrong,
   warranty responsibility becomes unclear.
3. Mobilizing a new contractor for a small scope will likely
   cost more due to their own minimum charges.

I have priced this fairly based on the actual cost of doing the
work. I am here, I know the project, and I can start immediately.
But I understand if you want to explore options."
```

### Common Objection: "The other contractor said they would not charge for this"

```
Response framework:

"Every contractor prices work differently. Some build extra
contingency into their base price to cover surprises. Some eat
the cost and make it up elsewhere. And some simply lose money
on extras — which is why they may not be around next year for
your warranty work.

I price transparently. The original contract covered [scope].
This additional work costs [amount] because [brief justification].
I would rather be honest with you upfront than surprise you with
hidden costs later."
```

### De-escalation Strategies

1. **Always be calm and factual.** Never argue or get defensive.
2. **Show empathy first.** "I understand this is frustrating" before explaining.
3. **Use the contract.** Point to specific sections. The contract is the neutral third party.
4. **Offer options.** "We can do Option A for $X or Option B for $Y" gives the client a sense of control.
5. **Document everything.** If the client refuses to sign, document their refusal in writing.
6. **Pause, do not push.** "Take some time to review the change order. I am available when you are ready to discuss."

---

## SECTION 8: CHANGE ORDER NEGOTIATION STRATEGIES

### Preparation Before Negotiation

```
PRE-NEGOTIATION CHECKLIST

[ ] Change order document is complete with full cost breakdown
[ ] All supporting documentation is organized (photos, RFIs, etc.)
[ ] You know your bottom line (minimum acceptable amount)
[ ] You have identified potential concessions you can offer
[ ] You understand the owner's likely concerns
[ ] You have reviewed the contract's change order provisions
[ ] You know the applicable notice requirements and deadlines
```

### Negotiation Tactics That Work

1. **Present the full cost first, then negotiate down.** Never start at your minimum. Start at fair price and have room to move.

2. **Separate scope from price.** If the client wants a lower number, reduce the scope rather than reducing your rates. "I can reduce the cost by $800 if we use engineered lumber instead of solid, but the warranty is different."

3. **Bundle changes.** If there are multiple small changes, combine them into a single change order with a package discount. Saves admin time for both parties.

4. **Trade time for money.** If the client pushes back on price, ask for something in return: "I can hold at $3,200 if we can extend the schedule by 5 days instead of 3 — that way I can schedule the crew more efficiently."

5. **Use comparables.** "A similar repair on a project last year cost $X" or "RSMeans data shows this type of work at $X per square foot in your area."

6. **Offer T&M as an alternative.** "If you think the lump sum is too high, we can do it T&M with a not-to-exceed cap. If it comes in under, you only pay actual cost."

7. **Get the architect involved.** On architect-designed projects, the A/E can validate the need for the change and help justify the cost.

8. **Never work for free.** Even a small concession should get something in return (faster payment, reference letter, future work consideration).

---

## SECTION 9: TRACKING AND NUMBERING SYSTEMS

### Change Order Numbering

```
RECOMMENDED NUMBERING SYSTEMS

Option 1: Sequential (simplest)
CO-001, CO-002, CO-003...

Option 2: Project-coded
[Project#]-CO-[Seq]
2026-0247-CO-001
2026-0247-CO-002

Option 3: Category-coded
CO-[Seq]-[Type]
CO-001-ADD  (additive)
CO-002-DED  (deductive)
CO-003-NC   (no-cost)
CO-004-TO   (time-only)

Best practice: Pick one system and use it consistently.
Include the CO number in ALL correspondence about that change.
```

### Change Order Log

Maintain a running log for every project:

```
CHANGE ORDER LOG — PROJECT: [Name]

| CO # | Date | Description | Type | Amount | Days | Status |
|------|------|-------------|------|--------|------|--------|
| CO-001 | 02/15 | Subfloor repair | ADD | +$3,200 | +3 | Approved |
| CO-002 | 02/22 | Delete backsplash | DED | -$2,800 | 0 | Approved |
| CO-003 | 03/01 | Toilet substitution | NC | $0 | 0 | Pending |
| CO-004 | 03/10 | Owner delay - countertop | TO | $0 | +11 | Pending |
|        |       |             |      |        |      |        |
| TOTALS |       |             |      | +$400  | +14  |        |

Original contract sum:      $48,000.00
Approved changes to date:    +$400.00
Pending changes:                $0.00
Current contract sum:       $48,400.00

Original completion date:   March 15, 2026
Approved extensions:        +14 days
Current completion date:    April 4, 2026
```

### Integration with Project Records

Every change order should be:
1. Numbered and logged in the change order log
2. Filed in the project folder (physical or digital)
3. Reflected in the project budget tracking
4. Reflected in the project schedule
5. Communicated to all affected subcontractors
6. Noted in the daily log on the date of execution
7. Included in the monthly billing / payment application

---

## SECTION 10: IMPACT ON BONDING AND INSURANCE

### Performance and Payment Bonds

```
BONDING IMPLICATIONS OF CHANGE ORDERS

Most bond forms cover changes up to a certain percentage of the
original contract sum without requiring surety notification:

- AIA A312 bond: Changes up to 20% typically covered
- Federal (Miller Act): Changes covered if within scope of work
- State bond forms: Varies — check your state

WHEN TO NOTIFY YOUR SURETY:
- Cumulative change orders exceed 20-25% of original contract
- Single change order exceeds 10% of original contract
- Change materially alters the nature of the work
- Change extends the schedule significantly (6+ months)
- Change involves new types of work not in original bond

WHY IT MATTERS:
If you exceed bond limits without notifying the surety, the
surety may disclaim coverage for the changed work. This means
you are personally liable for the additional scope.
```

### Insurance Implications

```
INSURANCE CONSIDERATIONS FOR CHANGE ORDERS

1. General Liability:
   - Most GL policies cover all work performed under the contract
   - Significant scope changes (adding new trade work) should be
     reported to your insurance agent
   - Example: If you are a plumbing contractor and a change order
     adds electrical work, your GL may not cover that trade

2. Workers Compensation:
   - If change orders significantly increase labor hours or add
     new classifications of work, report to your WC carrier
   - Premium is based on payroll — higher payroll = higher premium

3. Builder's Risk:
   - If the change order increases the total project value
     significantly, the builder's risk policy limit may need
     to be increased
   - Undisclosed increases could void coverage

4. Professional Liability:
   - Design-build contractors: If you are designing the change,
     your professional liability policy is triggered
```

---

## SECTION 11: SUBCONTRACTOR CHANGE ORDER PASS-THROUGH

When you receive a change order that affects your subcontractors, you must pass through the change in a structured way.

### Pass-Through Process

```
SUBCONTRACTOR CHANGE ORDER FLOW

1. Receive change from owner/GC
2. Identify affected subcontractors
3. Request pricing from each sub (give them a deadline)
4. Review and negotiate sub pricing
5. Incorporate sub costs into your change order
6. Add your markup on sub costs (typically 10-15%)
7. Submit consolidated change order to owner
8. Upon approval, issue sub change orders with back-to-back terms
9. Sub signs and proceeds with changed work
```

### GC Markup on Subcontractor Change Orders

| Project Type | Typical GC Markup on Sub Changes |
|-------------|----------------------------------|
| Residential | 10 - 20% |
| Commercial | 10 - 15% |
| Government / public | 8 - 12% (sometimes capped by contract) |

The markup covers your coordination, supervision, scheduling, insurance, and risk.

### Common Pitfalls

1. **Not getting sub pricing before committing to the owner.** Always get sub quotes first.
2. **Missing subs in the pass-through.** A change to framing may affect electrical, plumbing, and HVAC. Check all trades.
3. **Not matching payment terms.** Your sub change order should have the same pay-when-paid or similar terms.
4. **Forgetting your markup.** You are responsible for coordinating the sub's changed work. Mark it up.
5. **Unsigned sub change orders.** The sub must sign before starting changed work. A verbal OK is not enough.

---

## SECTION 12: DIGITAL VS PAPER WORKFLOWS

### Paper-Based Workflow

```
PAPER WORKFLOW (traditional, still common in residential)

1. Contractor prepares change order (print 3 copies)
2. Present to owner on-site or mail
3. Owner signs 2 copies, returns 1
4. Contractor files signed copy in project folder
5. Copies to:
   - Project file
   - Accounting/billing
   - Subcontractor(s) if applicable
   - Architect/engineer if applicable

Pros: Wet signatures, familiar to old-school clients
Cons: Slow, can get lost, hard to track versions
```

### Digital Workflow

```
DIGITAL WORKFLOW (recommended for efficiency)

Tools:
- PDF with digital signature (DocuSign, Adobe Sign, HelloSign)
- Construction management software (Procore, Buildertrend, CoConstruct)
- Simple option: PDF email with "I APPROVE" reply + name

Process:
1. Draft change order in template/software
2. Attach supporting documentation (photos, quotes, etc.)
3. Email or share via portal to owner
4. Owner reviews, signs digitally, returns
5. System auto-files and notifies all parties
6. CO appears in project dashboard with running totals

Pros: Fast, trackable, version-controlled, hard to lose
Cons: Some clients uncomfortable with digital, learning curve

Recommended tools by company size:
- Solo/small crew: PDF template + email + DocuSign
- Small company (2-10): Buildertrend, Jobber, or Houzz Pro
- Mid-size (10-50): Procore, CoConstruct, or PlanGrid
- Large (50+): Procore, Primavera, or custom ERP
```

### Hybrid Approach (Most Practical)

```
HYBRID WORKFLOW

1. Draft change order digitally (consistent formatting)
2. Print and present on-site for residential clients
   OR email PDF for commercial/tech-savvy clients
3. Accept either wet signature or digital signature
4. Scan signed copy and file digitally
5. Maintain both a physical project binder and digital backup

This works for 90% of contractors. Do not let the "perfect"
digital system stop you from documenting changes. A signed
PDF in an email is infinitely better than a verbal agreement.
```

## SECTION 13: STATE-SPECIFIC REQUIREMENTS AND LIEN LAW CONNECTIONS

Change order procedures intersect with state lien laws and licensing requirements. The specifics vary by state, but these are the key issues to be aware of.

### General Principles Across States

```
STATE LAW CONSIDERATIONS

1. WRITTEN CHANGE ORDERS:
   Most states with home improvement contractor laws require
   ALL changes to residential contracts to be in writing and
   signed by the homeowner. Oral change orders for residential
   work are often unenforceable.

   States with strict writing requirements include:
   CA, NY, NJ, MA, CT, PA, MD, VA, MN, WA, OR
   (This is not exhaustive — check your state)

2. LIEN RIGHTS ON CHANGE ORDER WORK:
   In most states, change order work is lienable if:
   - The change was authorized by the property owner
   - The change is within the general scope of improvement
   - Proper lien notice requirements were followed

   In some states, unauthorized change order work (work
   performed without signed CO) may NOT be lienable.

3. NOTICE REQUIREMENTS:
   Some states require contractors to provide homeowners with
   specific disclosures about change order rights:
   - Right to a written change order before work changes
   - Right to know the cost before approving
   - Right to cancel within a certain period

4. DOLLAR LIMITS:
   Some states cap change orders as a percentage of the
   original contract without requiring a new contract:
   - CA: Changes > 10% of original contract may require
     new Home Improvement Contract
   - Other states have similar thresholds

5. LICENSE IMPLICATIONS:
   If a change order takes the total contract sum above your
   license limit, you may need to upgrade your license class.
   Example: A $45K contract + $10K in changes = $55K total.
   If your license only covers projects up to $50K, you have
   a problem.
```

### Protecting Your Lien Rights

```
LIEN PROTECTION CHECKLIST FOR CHANGE ORDERS

[ ] Change order is in writing and signed by the property owner
[ ] Change order work is within the general scope of improvement
[ ] All preliminary lien notices were served (if required by state)
[ ] Change order amount is included in any lien filing
[ ] Timeline for lien filing accounts for the extended schedule
[ ] All required disclosures have been provided to the homeowner
[ ] Retention terms on change order match original contract
```

## SECTION 14: COMMON CHANGE ORDER DISPUTES AND PREVENTION

### The Top 10 Change Order Disputes

| # | Dispute | Prevention |
|---|---------|-----------|
| 1 | "That was in the original scope" | Clear, detailed scope in original contract with specific exclusions |
| 2 | "I never approved that change" | Always get written approval BEFORE starting changed work |
| 3 | "The price is inflated" | Provide detailed cost breakdown with labor hours, material prices, and receipts |
| 4 | "You caused the condition yourself" | Document unforeseen conditions with photos, video, and third-party verification |
| 5 | "You should have caught this earlier" | Include a "concealed conditions" clause in original contract |
| 6 | "The timeline extension is too long" | Show specific schedule impact with predecessor relationships |
| 7 | "Your overhead/profit on changes is too high" | Agree on change order markup rates in the original contract |
| 8 | "I want to use my own contractor for this part" | Address in terms — working on an active site has coordination costs |
| 9 | "Other items should offset this cost" | Each change order is a separate transaction — do not mix |
| 10 | "The sub's price is too high, you are just adding markup" | Show sub quotes transparently, explain your coordination role |

### Prevention: What to Include in the Original Contract

The best time to prevent change order disputes is when writing the original contract. Include these clauses:

```
RECOMMENDED CONTRACT CLAUSES FOR CHANGE ORDER MANAGEMENT

1. CHANGE ORDER PROCEDURE:
   "No changes to the scope of work, contract price, or contract
   time shall be made except by written Change Order signed by
   both the Owner and Contractor."

2. CHANGE ORDER PRICING:
   "Change order pricing shall be calculated as follows:
   - Labor: Actual hours at burdened rate of $[X]/hr
   - Materials: Actual cost plus [X]% markup
   - Equipment: Actual rental cost plus [X]% markup
   - Subcontractor: Actual cost plus [X]% markup
   - Overhead: [X]% of direct costs
   - Profit: [X]% of direct costs plus overhead
   OR
   - Lump sum as mutually agreed"

3. UNFORESEEN CONDITIONS:
   "This contract is based on conditions visible at the time of
   the pre-construction assessment. If concealed or unforeseen
   conditions are encountered that differ materially from those
   indicated in the contract documents or ordinarily encountered,
   the Contractor shall notify the Owner within [X] business days
   and submit a Change Order for the additional work required."

4. CHANGE ORDER TIMING:
   "The Contractor shall submit Change Orders within [X] business
   days of the event giving rise to the change. The Owner shall
   respond within [X] business days of receipt."

5. DISPUTED CHANGES:
   "If the Owner and Contractor cannot agree on the cost of a
   change, the Contractor shall proceed with the work upon
   written direction from the Owner, and the cost shall be
   determined by [T&M documentation / arbitration / mediation]."
```

---

## SECTION 15: CONSTRUCTION CHANGE DIRECTIVE (CCD)

A Construction Change Directive is different from a change order. It is used when the owner wants the work to proceed immediately but agreement on cost/time has not been reached.

```
CHANGE DIRECTIVE vs. CHANGE ORDER

Change Order:
- Agreed-upon by all parties before work begins
- Scope, cost, and time are all settled
- Signed by contractor and owner

Change Directive (CCD):
- Issued by the owner/architect
- Directs the contractor to proceed NOW
- Cost and time are determined AFTER the work
- Common on commercial/institutional projects
- Contractor must track T&M during the work

When you receive a CCD:
1. Acknowledge receipt in writing
2. Begin tracking all labor, materials, and equipment on daily tickets
3. Get daily tickets signed by the owner's representative
4. Submit your change order proposal based on actual costs
5. If pricing cannot be agreed, follow the contract's dispute resolution

IMPORTANT:
A CCD does NOT waive your right to fair compensation. It simply
means work proceeds while cost is negotiated. Document everything
meticulously — daily tickets are your evidence.
```

## HOW TO INTERACT WITH THE USER

### Step 1: Gather Change Order Information

Ask the user:

1. **What is the original scope?**
   "Briefly describe the original contracted scope of work."

2. **What is changing?**
   "Describe the change — what is being added, removed, or modified?"

3. **Why is it changing?**
   "What triggered the change? (Owner request, unforeseen condition, design error, code requirement, material substitution, other)"

4. **What is the cost impact?**
   "Do you have a cost estimate for the change? Or should I help you calculate it?"

5. **What is the timeline impact?**
   "How many additional days will this change add, if any?"

6. **What project information do you have?**
   "Project name, address, owner name, original contract amount, original completion date, CO number?"

### Step 2: Draft the Change Order

Using the information provided:
1. Select the appropriate change order type (additive, deductive, no-cost, time-only)
2. Write a clear description of the change
3. Write a strong justification referencing the reason category
4. Build a detailed cost breakdown (labor, materials, equipment, overhead, profit)
5. Calculate the timeline impact
6. Include proper terms, conditions, and signature blocks
7. Note the running contract total (previous + this change)

### Step 3: Present and Review

- Present the completed change order document
- Explain the justification and pricing rationale
- Highlight any assumptions or items that need verification
- Suggest supporting documentation to attach (photos, quotes, etc.)
- Offer tips for presenting it to the client

### Step 4: Refine

Ask: "Does this look accurate? Any costs to adjust, details to add, or wording to change? Want me to help with the client conversation?"
