Scope and Change Order Analysis

WHAT THIS SERVICE ADDRESSES

When a contractor bills for work claimed as outside the original scope, issues change orders you believe are excessive or duplicative, or delivers a project that does not match the contract, plans, or permit records, this practice provides the independent scope and change order analysis to determine what was agreed, what was built, and where the two diverge.

Years Writing, Pricing & Managing
Construction Scope and Change Orders

For more than 25 years, Scott Biller wrote scopes of work, priced and negotiated change orders, and managed contract performance as a licensed Class B contractor. He now evaluates those same documents as an independent expert — with the practitioner’s understanding of how scope is written, how change orders are priced, and where each is most likely to be disputed.

Scope of Work Analysis

Field-verified comparison of as-built conditions against the contractual scope, approved drawings, and permit records.

Change Order Review

Independent evaluation of whether claimed change orders reflect work outside the original scope and whether the work was performed.

Completion & Punch List

Field-verified assessment of substantial completion, punch list status, and conformance to close-out requirements.

Scope of Opinion

Scope of work and change order opinions in this practice area are developed through direct site inspection, contract and change order review, and evaluation against approved drawings, specifications, permit records, and applicable construction standards. The scope of analysis available includes:

Evaluating whether completed work conforms to the agreed scope, approved drawings, and permitted conditions — based on direct field measurement and observation, not document review alone

Establishing through direct measurement and observation whether completed work conforms to approved plans, specifications, and permitted scope — producing a field-grounded record established through direct observation and measurement, independent of any secondhand account of site conditions

Evaluating whether claimed change orders reflect work genuinely outside the original scope, whether the claimed extra work was performed, and whether the scope of work is accurately described in the change order documentation — the scope authorization question. Whether the amount charged for that work is supported is a billing-side determination addressed in Practice Area 02: Construction Cost Analysis

Evaluating whether the pricing of a claimed change order is consistent with the scope of work performed — assessed against published construction cost databases and direct market knowledge of how that category of work is estimated and priced by contractors in this region, not against a preferred cost figure

Identifying work billed as a change order that falls within the original contractual scope — producing an independent determination of what constituted agreed scope and what, if anything, was legitimately added

Evaluating whether a contractor deviated from agreed scope without documentation, owner disclosure, or authorized change order — a contractor’s judgment call that requires direct construction practice experience to evaluate with authority

Evaluating whether installed systems, assemblies, and components conform to the manufacturer’s published installation requirements as incorporated into the applicable contract, specifications, or product warranty conditions

Evaluating whether work was performed in conformance with permitted scope and jurisdictional approval records — identifying deviations between what was permitted, what was inspected, and what was built

Evaluating whether contractor draw requests accurately reflect the percentage of work completed at the time of submission — comparing billed completion percentages against field-documented progress to identify draws that overstate work in place, and evaluating whether claimed project milestones and completion stages conform to the draw schedule’s defined milestones and payment stages

Evaluating whether the conditions required for draw release were met at the time of the draw request — including required building inspections passed, owner-selected materials approved or delivered, stored materials verified on-site, lien waivers received from subcontractors, and bank inspection requirements for construction loan draws satisfied. Where a contractor submitted a draw before these conditions were met, field inspection and documentation review establish whether each condition was in fact satisfied at that time

Documenting incomplete or non-conforming work at claimed project completion against the agreed close-out scope and completion items — producing the field-verified record that supports or challenges retainage withholding and final payment determinations

Responding to opposing expert opinions on scope conformance, change order legitimacy, as-built conditions, and contract compliance — providing counsel with a documented analytical response before deposition or hearing

Where scope findings require independent cost quantification for remediation, completion, or payment dispute purposes, that analysis is addressed in Practice Area 02: Construction Cost Analysis. Both analyses are available from the same expert and the same field inspection record.

Scope of Work Analysis

Scope opinions are grounded in direct site inspection: as-built conditions are observed, measured, and documented against the project’s approved plans and permitted scope — a field-verified comparison built from direct observation, not from a third party’s site report.

Change Order Review

Evaluating a challenged change order requires someone who has been on the other side of those negotiations — who wrote scopes of work, priced and negotiated change orders, and managed subcontractors through disputed extra work. That position is what allows three questions to be answered with the same standing as the contractor who raised the claim: was the work genuinely outside the original scope, was it actually performed, and does the pricing reflect what the work required.

Completion & Punch List

Whether a project reached substantial completion — and what that means for punch list obligations and final close-out — requires a field-verified assessment against the completion standard applicable to the matter. Where retainage release or payment-side questions are also at issue, those are addressed in Practice Area 02: Construction Cost Analysis from the same site inspection.

Practice Areas

COMMON SITUATIONS THIS PRACTICE ADDRESSES

The contractor performed work beyond the original contract and is seeking additional payment. Change orders have been issued that you believe duplicate work already in the original scope. The completed project does not conform to the approved drawings or permitted scope. Work was performed without an authorized change order and the contractor is now billing for it as an extra. The project was declared complete but items remain unfinished or non-conforming. An opposing expert has offered a scope conformance opinion that does not reflect what the field actually shows.

In each, the analysis begins with what the matter requires — direct field inspection, contract and change order review, or both — and the determination is formed independently. The starting point is a direct conversation; no formal intake process is required.

If You Are a Homeowner

If a contractor billed for work you did not agree to, built something that does not match the plans or contract, or issued change orders you believe were not justified — this practice provides an independent determination of what the contract required, what was actually built, and where the two do not match. The answer comes from a direct inspection of the property and the contractor’s working knowledge of how scope is defined and how change orders are documented in practice.

WHAT THIS MEANS FOR YOUR SITUATION

If the contractor billed you for work that was not in the original contract, this practice can document what the agreed scope included and what was added — and whether the addition was authorized as a change order or falls within the work the contractor was already engaged to perform. If change orders are in dispute, each is evaluated independently against three questions: was the work genuinely outside the original scope, was it actually performed, and does the price reflect what the work required — producing an independent determination on each point. If the project was declared complete but the work does not match what the plans, contract, or permits required, a direct field inspection establishes the facts from observation — not from the contractor’s paperwork or your own records. In each situation, the answer is formed independently from what the field and the documents show.

Admissibility
Across Jurisdictions

Scope of work and change order opinions are developed with the admissibility requirements of each jurisdiction in mind.

Across all three jurisdictions, opinions are formed from direct field observation and construction contracting experience developed independent of the pending litigation — not manufactured for the purpose of testifying. The analytical approach reflects the specific contract documents, field conditions, and change order records at issue, not a generalized framework applied to a category of dispute.

Virginia

Opinions are formed in accordance with Va. Code § 8.01-401.1 and Va. Sup. Ct. R. 2:702, grounded in facts and data observed or made known to the expert. Comparing field-verified as-built conditions against contractual scope, approved drawings, and permit records is grounded in direct construction practice and widely accepted within the residential construction field.

Maryland

Opinions are developed under Maryland Rule 5-702 and the Daubert standard adopted in Rochkind v. Stevenson, 471 Md. 1 (2020): based on sufficient facts or data, the product of reliable principles and methods, and those methods reliably applied to the case. Methodology is grounded in direct field observation, contract document review, and the practitioner’s knowledge of construction contracting standards.

West Virginia

Opinions are developed under W. Va. R. Evid. 702. Contract scope and as-built comparison through direct inspection is established, widely accepted practice within the construction industry and does not implicate the heightened scrutiny under Rule 702(b) reserved for novel science.

Deposition & Trial Experience

Scope and change order opinions in this practice have been subjected to cross-examination across Circuit Court, General District Court, U.S. District Court, and arbitration. The analytical basis for each opinion — the contract documents reviewed, the field conditions observed, and the methodology applied — is recorded and available before deposition begins, not reconstructed in response to it.

Expert reports are prepared to meet disclosure requirements under applicable court rules. Rebuttal analyses are available where opposing expert opinions raise issues of methodology, field observation, or contract interpretation. Prior reports, transcripts, and disclosure materials are available for pre-retention review on request.

WHAT THESE MATTERS HAVE IN COMMON

Each involved a dispute where the question of what was agreed, what was built, and where the two diverged could not be resolved from documents alone. Behind each was a property owner facing the same question: was this what we agreed to, and if not, who is responsible? An independent scope analysis — grounded in field observation and the practitioner’s knowledge of how construction scope is written and how change orders are documented.
