Robert A. Di Alto is a Participating Member of the International Code Council (ICC) and an ICC Certified Residential Building Inspector (Certificate No. 10298317). His certification is publicly verifiable at iccsafe.org/search-for-certified-professionals.
I am a retired licensed general contractor with decades of experience in both commercial and residential construction. I am also a master carpenter and trained kitchen and bath designer. That breadth of hands-on experience is what sets me apart — I don't just evaluate defects from the outside; I understand the decisions, sequencing, trade standards, and code requirements that govern every phase of a project, from foundation to finish work.
Prior to founding Phoenix Defect Resolution Partners LLC, Robert served as a state investigations agent for the AZROC (Arizona Registrar of Contractors) — giving him unique insight into contractor accountability, licensing law, and the investigative standards that govern the construction industry in Arizona. That background informs every inspection and report he produces.
Robert is retained by plaintiff and defense counsel, insurance carriers, and property owners across Arizona, California, Nevada, and nationally — covering residential subdivisions, commercial developments, HOA communities, and mixed-use projects.
Phoenix Defect Resolution Partners LLC brings decades of hands-on construction industry knowledge to every case. Robert Di Alto is a licensed, certified professional who has built, inspected, and assessed thousands of residential and commercial projects across the Southwest and beyond.
We are retained by plaintiffs, defendants, insurance carriers, property managers, and home owners alike — a testament to our independence, credibility, and the quality of our work product.
Phoenix Defect Resolution Partners was not built on credentials. It was built on two careers — and a chance meeting on the floor of the Home Depot.
That is where Tracy and I met. Both of us were already deep in the construction industry "landscape." It felt fitting then and it still does — because this firm is, in every meaningful sense, a product of that shared foundation.
My background spans decades of hands-on work across general contracting, project oversight, code compliance, and construction standards throughout the Southwest, East Coast, Hawaiian Islands and South America. Long before I held any formal investigative title, I had developed the forensic eye, the documentation discipline, and the technical fluency that serious expert work demands. That depth is what led the Arizona Registrar of Contractors (AZROC) to hire me as an investigations agent. The AZROC didn't teach me how to investigate — it gave me a formal platform to apply skills I had spent a career building.
Tracy's expertise runs just as deep, in a distinct and complementary direction. Thirty years in commercial and residential flooring operations — managing installation teams, overseeing subcontractors, conducting site quality assurance, coordinating projects from pre-construction through close-out, and scaling installation programs from $1M to over $35M annually. She holds an AA in Interior Design with a focus in flooring, kitchen and bath design, finishes, and installation standards. At Phoenix Defect Resolution Partners she leads operations and brings a level of materials, workmanship, and installation expertise that very few firms in this space can match.
Then I found myself on the other side of the process
I experienced firsthand the same kind of dispute I had spent years evaluating professionally. When a contractor we hired for a property improvement project made unauthorized changes to design, materials, and structural elements that were neither disclosed nor approved by the City of Phoenix, I withheld final payment. The contractor recorded an unlawful mechanic's lien and filed suit in Maricopa County Superior Court.
In support of counsel, I assembled the forensic documentation, photographic evidence, physical exhibits, research, and report materials that helped establish the facts. The arbitrator found in my favor, and the lien was removed.
That experience also revealed a serious limitation in the system: once civil litigation began, my Arizona Registrar of Contractors complaint was dismissed under the agency's parallel proceedings policy.
That reality helped define our mission. Tracy and I created a firm built to provide what is often missing in these matters: experienced construction insight, forensic rigor, and independent support for attorneys, insurers, and property owners confronting complex defect and dispute issues.
"We retained Robert as a defense expert and his GC background was invaluable. He understood the sequencing of the work at a level that completely reframed the narrative and litigation was averted with minimal expense to our client as opposed to litigation."
"His AZROC background gave our investigation instant credibility. He knew exactly what standards apply and how investigators evaluate contractor conduct. That made all the difference in our claim."
"Robert identified defects that two prior inspectors had missed entirely. His combination of code knowledge and actual trade experience is rare. I will not hire another expert witness for construction defect cases."
"Their clear report made settlement fast and fair. Pre-suit mediation delivered full insurance-funded remediation without ever stepping into a courtroom."
"Thorough analysis drove swift insurance resolution. Pre-suit mediation secured complete exterior remediation — exactly the outcome our client needed."
"Precision expertise for high-elevation conditions. The forensic analysis resulted in full pre-suit roof reinforcement — something no other inspector had been able to establish."
"Turned a denied claim into full resolution — no litigation. The forensic analysis overturned the denial and secured complete roof replacement."
"Highly credible and efficient on every detail. Neutral mediation achieved global builder-funded repairs for all affected luxury townhomes — without a single lawsuit filed."
"Data-driven and avoided courtroom battles entirely. The defect report secured a full repipe in pre-litigation settlement — fast, precise, and effective."
"Responsive expertise delivered the exact outcome needed. Load testing established the deficiency clearly and led to complete system replacement — resolved before arbitration."
"Expert services that truly prevent litigation. The on-site evaluation secured rapid insurance-funded reinforcements and kept the matter out of court entirely."

"Impartial and highly effective throughout. The engineering review produced a mediated settlement that resolved complex structural and foundation claims without litigation."
"Exceptional technical analysis and communication. The forensic evaluation identified the full scope of defects and secured complete pre-suit repairs for our client."
"Efficient and technically precise from start to finish. The plumbing and mechanical defect report enabled a quick, fully negotiated resolution that avoided protracted litigation."
"Our company's lakeside executive property had documented envelope failures that two prior consultants couldn't resolve. Robert's forensic report cut through the ambiguity immediately — the findings supported a full pre-litigation settlement that covered every remediation item our facilities team had flagged."
From initial retention to final resolution, we follow a structured, transparent process built around one goal — producing defensible, credible findings that hold up under scrutiny of opposing experts and cross-examination. Here is what you can expect when you retain Phoenix Defect Resolution Partners LLC.
We begin by reviewing all relevant case documents — prior inspection reports, photographs, contracts, and correspondence. We discuss the allegations with retaining counsel, clarify the scope of our engagement, identify scheduling constraints, and establish a clear written engagement agreement. Our goal at intake is to understand not just what is alleged, but what questions the case actually needs answered.
Every engagement includes a thorough on-site forensic inspection. We document conditions with comprehensive photography, take measurements, note code-relevant observations, and — where appropriate — collect physical samples or conduct moisture testing. We inspect not just the alleged defect areas but the surrounding conditions that establish context, causation, and scope. All site visits are coordinated professionally with all parties as required.
Findings are analyzed against the International Residential Code (IRC), International Building Code (IBC), Arizona building standards, manufacturer installation requirements, and accepted industry practice. We produce a written expert report that clearly identifies each defect, its cause, the applicable standard violated, and the resulting damage or risk. Reports are well-referenced, supported by labeled photographs, and written to withstand peer review and rigorous cross-examination.
Robert is available for deposition, mediation, arbitration, and trial testimony as needed. He presents technical findings clearly and confidently — without jargon that confuses juries or language opposing counsel can exploit. Beyond formal testimony, we remain available throughout litigation to answer counsel's questions, review opposing expert reports, assist with discovery, and provide supplemental analysis as the case develops. We stay engaged until the matter is fully resolved.
Construction defect matters move quickly. Early expert involvement helps preserve evidence, define the technical issues, and protect your position. We respond to all inquiries within 24 hours.
