Construction defect litigation can be challenging, with many procedural guidelines that should be considered by both sides of the litigation. Expert witnesses can help to ensure that the case is brought and proceeds correctly. With their work beginning at the outset and continuing through resolution of the case, experts ensure that the allegations are based on evidence, not assumptions or guesswork.
Types of Expert Witnesses
Construction defect cases are technical by nature. Proving what went wrong and what it will cost to fix typically requires multiple experts.
Depending on the claim, a case may feature:
- Structural or forensic engineers who identify the cause of a defect
- Building envelope or roofing consultants who investigate water intrusion, leaks, and waterproofing failures
- Geotechnical engineers who evaluate soil conditions and whether the foundation was properly designed and prepared for the site
- Cost estimators or general contractors who calculate the reasonable cost of repair
- Appraisers or real estate valuation experts who assess how a defect has diminished the property’s market value
- Standard-of-care experts (e.g., licensed architects, engineers, or contractors) who testify about whether the work met accepted industry practices
- Mechanical, electrical, and plumbing (MEP) engineers who identify defects involving HVAC systems, electrical wiring, or plumbing failures rather than the structure itself.
- Mold and environmental/industrial hygiene experts to assess whether water intrusion or moisture issues have led to mold growth or air quality concerns.
- Accounting or forensic economists who calculate lost profits, diminished business income, or other economic damages tied to construction delays or defects.
Each expert plays a distinct role in the claims and court processes. A case often needs several working together to establish liability and damages.
The Role of Construction Defect Experts: Pre-Litigation Stage
Engagement of experts in construction-related disputes typically differs from other forms of litigation, as experts are often consulted and retained early in the process—before a lawsuit is filed. In cases involving alleged construction defects, professionals such as structural engineers, building science experts, certified mold consultants, and industrial hygienists are brought in to inspect the property for potential issues. These experts play an integral role from the outset, conducting thorough inspections, documenting findings through photographs, and preparing detailed written reports.
The expert report is a critical component in preparing the claimant’s case prior to pursuing legal action, as it must identify the construction defects sufficiently to provide the builder with reasonable notice of all claims. In accordance with the Residential Construction Liability Act (RCLA), a demand letter is required before initiating legal proceedings and should specify the defects observed on the property. The inspection and resulting expert report are vital for substantiating these claims, rendering them indispensable in the early phases of dispute resolution.
The Role of Construction Defect Experts: Litigation Stage
Should the dispute advance to litigation, expert findings will serve as principal evidence supporting the specific claims against the defendants. Throughout the discovery process, construction defect experts are typically called upon to testify, most often through deposition and subsequent cross-examination to explain and defend their conclusions.
Our experts have withstood this process many times and have proven the merits and validity of their opinions. By being prepared, they can withstand intense cross-examination and thereby strengthen the overall case by effectively communicating their findings and conclusions.
How Expert Witnesses Impact Settlement Negotiations
Expert opinions frequently help move a case toward settlement. A well-supported expert report gives an insurer or opposing party a concrete idea of their liability exposure and what it costs to repair or replace defective work.
When both sides retain experts and those opinions largely align on causation, negotiations tend to move faster because the central dispute has narrowed to what it costs to fix the issue.
However, when the parties’ experts reach different conclusions about what caused a defect, settlement becomes harder, since neither side can confidently predict how a jury will weigh competing evidence. In these situations, a party with a stronger, more thoroughly documented expert opinion may be more persuasive to a judge or jury.
How Courts Evaluate Expert Testimony in Texas
Texas courts do not always accept an expert’s credentials at face value. Under Texas Rule of Evidence 702 and related common law (E.I. du Pont de Nemours & Co. v. Robinson), a trial judge must determine that expert testimony is both relevant and based on a reliable foundation before a jury ever hears it.
To assess reliability, Texas courts generally consider factors such as:
- Whether the expert’s theory or technique has been tested
- Whether it has been subjected to peer review or publication
- The known or potential rate of error
- Whether the technique is generally accepted within the relevant professional community
- The extent to which the opinion relies on the expert’s subjective interpretation rather than an objective methodology
An expert’s credentials alone are not enough. Texas courts have excluded testimony from qualified experts whose methodology was too subjective or who failed to rule out other possible causes of the damage.
Either side can challenge the other’s expert before trial, thoroughly vetting and preparing your experts is often just as important as the underlying opinion itself.
The experts, practitioners, and clients all form a strong team that is able to consider the science, the law, and the experience of each respective member. Each one plays an important role in creating a strong case based on facts and supported by the evidence collected by the experts. In construction defect litigation, expert witnesses are crucial to the overall success of the case, particularly in matters involving property owners’ associations or shared property construction claims.
Property law recognizes three primary forms of joint ownership: (1) Tenancy in Common, (2) Joint Tenancy with Right of Survivorship, and (3) Tenancy by the Entirety (although this type is not formally recognized in Texas, a similar effect can be achieved for married couples). Each form carries unique rights and responsibilities, and understanding the distinctions is important.
