10.3 Scoping the Loss, Detailed Line-Item Estimating & Overhead and Profit

Key Takeaways

  • Loss scoping is the systematic physical inspection and recording of all direct physical damage and necessary trade operations, utilizing room-by-room measurements, opening deductions, and advanced diagnostic tools.
  • Diagnostic scoping utilizes non-penetrating moisture meters, invasive pin-type resistance meters, infrared thermal cameras, and borescopes for destructive cavity inspection to identify hidden water migration and smoke travel.
  • Industry-standard unit-cost estimating platforms (such as Xactimate) decompose reconstruction tasks into discrete unit costs covering raw materials, direct trade labor, equipment, removal/tear-out labor, and material waste factors.
  • General Contractor Overhead and Profit (O&P)—traditionally '10 and 10'—compensates the general contractor for administrative operating expenses and entrepreneurial profit; under New York law (Mazzocki v. State Farm), O&P must be included in ACV estimates whenever GC coordination is reasonably necessary.
  • Regulation 64 (11 NYCRR § 216.6) requires fair and reasonable offers but contains no specific matching rule, so matching disputes are argued from the policy's like-kind-and-quality wording, documentation, and appraisal for amount disputes.

Scoping the Loss, Detailed Line-Item Estimating & Overhead and Profit

Quick Answer: Scoping is the detailed physical inspection and recording of all direct physical damage and necessary repair operations across an insured structure. Public adjusters utilize diagnostic tools like moisture meters, infrared thermal cameras, and borescopes to uncover hidden damage. Estimates are structured using unit-cost platforms (e.g., Xactimate), breaking tasks into labor, materials, equipment, and demolition. Under New York law (Mazzocki v. State Farm), General Contractor Overhead and Profit (10 & 10 O&P) belongs in replacement cost and Actual Cash Value estimates whenever it is reasonably likely a general contractor will be needed. Regulation 64 (11 NYCRR § 216.6) requires fair and reasonable offers but contains no specific matching rule, so matching disputes are argued from the policy wording and the facts.

Preparing a comprehensive, bulletproof damage estimate is the core operational competency of a licensed New York public adjuster. While insurance company adjusters frequently perform superficial walk-through inspections and compile abbreviated scopes that omit essential construction steps, the public adjuster must capture every affected building assembly, calculate precise trade labor requirements, and advocate for general contractor overhead and profit and for like-kind-and-quality restoration, including matching where the policy wording and facts support it.


The Comprehensive Scoping Process

Scoping is the systematic, on-site investigative process of inspecting, quantifying, and documenting all direct physical damage to real and personal property resulting from a covered peril, along with defining the complete scope of construction operations necessary to restore the property to its pre-loss condition.

Systematic Physical Inspection Protocols

A professional scope follows a rigid, organized protocol to ensure that no damage is overlooked:

  1. Exterior Envelope & Structural Perimeter: Inspection begins with the foundation, exterior elevations, windows, doors, roof coverings, flashing, chimneys, and exterior mechanical equipment. The adjuster notes structural deflection, racking, thermal cracking, and wind or water entry points.
  2. Room-by-Room Directional Walkthrough: Interior inspection must be executed room-by-room in an unbroken logical sequence (e.g., clockwise starting from the main foyer). For each room, the adjuster records:
    • Exact physical dimensions: length, width, and ceiling height.
    • Openings: exact dimensions of all doors, windows, and archways (deducted from surface area calculations for painting and drywall).
    • Identification of all six room planes: floor, ceiling, and four individual walls.
    • Assemblies and fixtures: baseboards, crown molding, casing, electrical receptacles, light fixtures, HVAC registers, cabinetry, and countertops.
  3. Macro to Micro Sequencing: The adjuster assesses primary structural framing first (studs, joists, rafters), followed by sub-assemblies (insulation, vapor barriers, subflooring), and finally finished surfaces and trim.

Advanced Diagnostic Scoping Tools

Visual inspection alone cannot detect hidden water migration, concealed electrical arcing, or soot travel through interstitial wall cavities. Public adjusters utilize sophisticated diagnostic instruments:

Diagnostic InstrumentTechnology / FunctionPractical Scoping Application
Non-Penetrating Moisture MeterRadio frequency / dielectric capacitance; scans up to 3/4" deep without damaging finishesRapid non-destructive screening of tiled bathroom floors, plaster walls, and hardwood flooring
Penetrating (Pin-Type) Moisture MeterElectrical resistance measured across two insulated pins driven into substrateVerifies exact moisture content (% WME) in structural wall framing, sill plates, and wood subflooring
Infrared (FLIR) Thermal CameraDetects subtle infrared surface temperature differentials created by evaporative coolingMaps hidden moisture migration paths behind drywall, inside insulation, and under roofing membranes
Optical Borescope / Cavity Inspection CameraFlexible illuminated fiber-optic probe inserted through 1/4" drilled access holesInspects interior wall cavities for hidden soot residue, burnt wiring, wet fiberglass batts, and mold growth
Aerosol Smoke Pencils & Particle CountersGenerates visible draft currents and measures micron-level airborne particulate loadsIdentifies pressure differentials, ductwork breach points, and structural air leakage pathways

Invasive & Destructive Cavity Testing

Where smoke or water has penetrated behind wall assemblies, public adjusters must perform destructive testing (with the policyholder's permission and notification to the carrier):

  • Removing baseboards and cutting 6"x6" inspection portals in drywall to examine bottom wall plates and cavity insulation;
  • Lifting carpeting and pulling up tack strips to test particleboard or plywood subflooring for delamination;
  • Opening suspended ceiling tiles to inspect structural plenum spaces and HVAC ductwork.

Photographic and Video Documentation Protocols

Photographs constitute the primary factual evidence supporting the public adjuster's claim. In New York claim negotiations, an estimate unsupported by photographic proof is easily discredited by carrier examiners.

Photographic Hierarchy

  1. Overview Photographs: Wide-angle establishing shots showing the entire room or exterior elevation, capturing orientation, layout, and general condition.
  2. Medium-Range Photographs: Contextual images capturing specific assemblies (e.g., an entire damaged kitchen cabinet run, a complete wall showing water staining and baseboard swelling).
  3. Macro (Close-Up) Detail Photographs: High-resolution close-ups capturing physical failure characteristics (e.g., fractured roofing matting, charred electrical conductors, delaminated vinyl flooring edges, or moisture meter digital readout screens showing elevated percentages against the specific wall plate).

Evidence Preservation & Spoliation Rules

Under New York civil jurisprudence, spoliation of evidence—the intentional or negligent destruction, alteration, or failure to preserve physical evidence relevant to a claim or subrogation action—can result in severe evidentiary sanctions or total claim forfeiture.

  • Preservation Protocol: The public adjuster must physically preserve failed components (such as a burst brass plumbing elbow, an appliance supply hose, or a defective circuit breaker).
  • Notice to Carrier: Before discarding damaged building materials or appliances that may matter to causation or subrogation, the adjuster should give the insurer written notice and a reasonable opportunity for its engineers or subrogation investigators to inspect them.

Detailed Unit-Cost Line-Item Estimating & Xactimate Structure

In the property adjusting industry, estimates are prepared using computerized unit-cost estimating software—most notably Xactimate (developed by Verisk) and Symbility (CoreLogic).

Structure of an Xactimate Line Item

Every line item in a professional property estimate contains five core elements:

  1. Category Code (CAT): Identifies the general trade classification (e.g., DRY for Drywall, RFG for Roofing, PLA for Plaster, ELE for Electrical, PNT for Painting).
  2. Selector Code (SEL): Identifies the specific task, material grade, and thickness (e.g., 1/2 for 1/2" drywall hung, taped, floated, ready for paint; LF for lead flashing; AV for architectural shingles).
  3. Action / Activity Suffix: Defines the scope of the operation:
    • + : Supply and Install (Material + Labor)
    • - : Remove / Demolish (Labor to tear out and bag/haul only)
    • & : Remove and Replace (Tear out existing, then furnish and install new)
    • R : Detach and Reset (Carefully remove item, store safely, and reinstall after repairs)
  4. Quantity and Unit of Measurement: Calculated from physical field measurements (e.g., SF for square feet, SY for square yards, LF for linear feet, EA for each, SQ for roofing squares [100 sq ft]).
  5. Unit Price Breakdown: Unit costs come from price lists researched for specific geographic pricing regions and updated periodically to reflect local trade rates.

Component Breakdown of an Industry Unit Cost

A standard Xactimate unit cost comprises four distinct economic components:

  • Direct Material Cost: Wholesale cost of materials, fasteners, adhesives, delivery charges, and local sales tax.
  • Direct Trade Labor Cost: Direct hourly wage of the skilled craftsman plus the Labor Burden (payroll taxes, FICA, FUTA, State Unemployment Insurance [SUI], Workers' Compensation insurance, and mandatory contractor liability insurance).
  • Equipment Usage: Cost of specialized machinery (scaffolding, HEPA air filtration scrubbers, commercial dehumidifiers, power nailers, dumpsters).
  • Material Waste Factor: Realistic material cutting and fitting waste added to gross measurements (typically 10% to 15% on valley/hip roofing, 10% on drywall, and 10% to 15% on pattern-matched carpet and tile).

General Contractor Overhead & Profit (O&P)

In construction and property restoration, when a project requires coordinating multiple specialized trades, a licensed General Contractor (GC) must be retained to manage the reconstruction. The GC is entitled to compensation for operational business expenses and managerial risk through Overhead and Profit (O&P).

The Standard "10 and 10"

The industry benchmark for general contractor supervision is 10% Overhead and 10% Profit:

  • General Overhead (10%): Fixed, indirect operational costs required to maintain a legitimate contracting enterprise that cannot be attributed to a single specific line item. This includes maintaining a physical office, administrative and billing staff, general liability and umbrella insurance, contractor licensing fees, project management salaries, vehicle fleet depreciation, legal and accounting fees, and capital equipment costs.
  • Contractor Profit (10%): The net financial return and entrepreneurial reward earned by the general contractor for assuming total contractual, structural, and financial liability for executing the construction project in compliance with building codes and manufacturer warranties.

Additive vs. Compounding (Cumulative) Calculation

In estimating software, adjusters encounter two distinct mathematical methods for applying O&P:

  1. Additive Method (Industry Standard / Standard Xactimate Default): Overhead=Direct Construction Subtotal×10%\text{Overhead} = \text{Direct Construction Subtotal} \times 10\% Profit=Direct Construction Subtotal×10%\text{Profit} = \text{Direct Construction Subtotal} \times 10\% Total with O&P=Subtotal+(Subtotal×0.10)+(Subtotal×0.10)=Subtotal×1.20\text{Total with O\&P} = \text{Subtotal} + (\text{Subtotal} \times 0.10) + (\text{Subtotal} \times 0.10) = \mathbf{\text{Subtotal} \times 1.20} Result: Exactly 20.0% is added to the subtotal.

  2. Compounding (Cumulative) Method: Subtotal with Overhead=Direct Construction Subtotal×1.10\text{Subtotal with Overhead} = \text{Direct Construction Subtotal} \times 1.10 Total with O&P=(Subtotal with Overhead)×1.10=Subtotal×1.21\text{Total with O\&P} = (\text{Subtotal with Overhead}) \times 1.10 = \mathbf{\text{Subtotal} \times 1.21} Result: Because profit is calculated on top of overhead, the effective multiplier is 21.0%.

Public adjusters must review the carrier's calculation settings. In complex commercial losses, the 1.0% spread between additive and cumulative O&P represents thousands of dollars in legitimate indemnity.


Legal and Regulatory Standards for O&P in New York

Insurance carriers routinely attempt to withhold or eliminate O&P from claim estimates using two standard insurer arguments:

  1. "The insured has not yet hired a general contractor, so O&P has not been incurred."
  2. "The repair only involves two trades, so general contractor coordination is not necessary" (the so-called "Three Trades Rule").

The Landmark Ruling: Mazzocki v. State Farm

In Mazzocki v. State Farm Fire & Casualty Corp. (1 A.D.3d 9, 766 N.Y.S.2d 719 [3d Dept. 2003]), the New York Supreme Court, Appellate Division, established definitive, binding principles governing O&P in New York property claims:

  • O&P in Replacement Cost and ACV: The court held that where it is reasonably likely that the services of a general contractor will be required, the policy's "replacement cost" includes general contractor overhead and profit, so the Actual Cash Value (ACV) payment derived from replacement cost must include it too.
  • The Test Is Likelihood, Not Incurred Cost: Because ACV is paid before repairs are done, the court tied O&P to whether a general contractor is reasonably likely to be needed for the repair, not to whether one has already been hired.

The "Three Trades" Guideline vs. Operational Complexity

Insurers often apply a rule of thumb that O&P is payable only when three or more trades are involved (for example, drywall, electrical, and flooring). The Mazzocki test is whether a general contractor is reasonably likely to be needed, a question of operational complexity and coordination rather than a rigid trade count. If a fire causes complex structural damage involving only two trades (such as structural steel framing and specialized industrial masonry) requiring critical path scheduling, engineering supervision, municipal permitting, and safety scaffolding, GC overhead and profit belongs in the estimate under the Mazzocki test.


Material Matching in New York

A common dispute arises when a covered peril damages part of a uniform assembly, such as 15 vinyl siding panels, a 100-square-foot section of shingles, or part of a continuous hardwood floor, and matching replacement material cannot be found because it has been discontinued or has weathered to a different color.

What Regulation 64 Does, and Does Not, Say

Regulation 64 (11 NYCRR § 216.6(a)) requires that, where there is no dispute as to coverage, an insurer offer amounts that are fair and reasonable as shown by its investigation, within policy limits and in accordance with the policy provisions. Regulation 64 contains no specific matching rule. Unlike some states, New York has not adopted a regulation that expressly requires replacing undamaged adjoining material to achieve a reasonable match.

How Matching Is Argued

  • Policy wording: replacement cost forms promise repair or replacement with material of like kind and quality, or with equivalent construction for equivalent use. A patch that leaves an obviously mismatched roof slope or floor field is arguably not "like kind and quality" restoration.
  • Facts and documentation: photographs, manufacturer discontinuation letters, and samples showing the mismatch; whether an architectural break (a door threshold, a corner, a separate elevation) makes a partial repair reasonable.
  • Amount disputes: where coverage is admitted and the disagreement is over how much work is needed to restore the property, the appraisal clause can resolve the amount (Section 11.3). Whether the policy covers undamaged material at all is a coverage question for negotiation or the courts.
  • Unfair claim practices: if an insurer denies part of a claim, § 216.3(b) requires it to cite the specific policy provision in writing, and § 216.6(c) requires a written acceptance or rejection within the regulation's deadlines.

Practical Examples

  1. Continuous flooring: water damages hardwood in a hallway that runs without a threshold into the living room. The PA documents the continuous field, discontinued stain, and board width, and argues that like-kind-and-quality restoration requires refinishing or replacing the continuous area. The insurer may argue that the policy pays only for the damaged boards.
  2. Siding on one elevation: where damaged siding is discontinued, the argument is strongest for the entire damaged elevation, and weaker for undamaged elevations separated by corners.
  3. Cabinet runs: when damaged base cabinets cannot be matched to the uppers in finish and profile, the PA documents the mismatch and argues for refacing or replacing the run.
