  • Sales Expert Was Allowed to Opine on the Failure of the Swing Scaffolding System

    Sales Expert Was Allowed to Opine on the Failure of the Swing Scaffolding System

    This personal injury suit began at a construction site at Ochsner’s Lafayette General Medical Center. Charles’ employer, FL Crane & Sons, Inc. (“FL Crane”), was hired to install “z-girts, insulation, and stucco” on the Project building. To work on the building’s side, FL Crane procured swing scaffolding from Max Access. The scaffolding system they used was called the “Rolling Roof Rig.”

    On May 16, 2022, while Charles was working atop the Rolling Roof Rig at the Project, other workers lifted three porta potties for cleaning. Inadvertently, the porta potties, while being hoisted up, caught the tieback line that secured the scaffolding system. This entanglement caused the scaffolding system to collapse, severing Charles’ right arm in the process.

    Max Access argued that (1) Plaintiffs’ proffered witness, Brant Lacombe is not a qualified witness and (2) even if he is, his opinions did not satisfy Rule 702.

    Sales Expert Witness

    Brant Lacombe has fifteen years of experience as a swing scaffolding salesperson in addition to his designation as an OSHA-competent trainer who teaches employees how to use swing scaffoldings.

    Discussion by the Court

    1. Expert’s Qualification

    Here, it is undisputed that Lacombe is not an expert by way of education—his college degree is in criminal justice, not engineering.

    Ordinarily, Lacombe’s experience as a salesperson would be deemed too far removed from the scope of his testimony—why a scaffolding system, like the one he sold, failed. 

    Lacombe’s duties as a salesperson included not only sales, but also assisting crews with rigging to ensure the “job get[s] done.” Lacombe first said that he performed such tasks “plenty of times in [his] career,” but later states, “it wasn’t [his] primary function” and only did so “a handful of times over [his] career.”

    Max Access also asserted that Lacombe’s OSHA-related training was inadequate. Specifically, they argued that his initial OSHA 10 training was from “years ago” and he only had one other employer-administered two-to-three-day class.

    Given his experience with assisting crews in rigging swing scaffolds and his OSHA competency, the Court is unconvinced by Max Access’ arguments that Lacombe is not qualified as an expert.

    2. Expert’s Opinions

    a. Lacombe’s First Opinion

    Lacombe’s first opinion is that:

    Max Access, LLC had an obligation to properly assemble the swing stage scaffolding and rigging. Proper assembly requires insertion of the codder pins through the beam splice as well as the hole in the beam tube. The purpose of inserting the codder pins through the beam and the beam tube is to prevent the connection from being separated.

    As Max Access pointed out, however, this statement is not an opinion. Max Access agreed it had the above-stated obligation. Nevertheless, Plaintiffs argued that this testimony is necessary to show “why Max Access was obligated to set up the swing stages.” But Plaintiffs made no showing, let alone a showing by a preponderance of the evidence, on how this will assist the factfinder in “understand[ing] the evidence or determin[ing] a fact in issue.” 

    Thus, the Court concluded Lacombe cannot proffer his first opinion as it failed to meet Rule 702(a)’s requirement that the opinion “help the trier of fact to understand the evidence or determine a fact in issue.” 

    b. Lacombe’s Second Opinion

    Lacombe’s second opinion is that:

    The swing scaffolding failed because the roof rigging separated at the beam and the beam tube. Photos taken of the beam splice on the 5th floor show that the pin was inserted through the beam splice. Photos of the back beam on the 11th floor show that the holes in the beam had not been torn or damaged. This shows that the back beam was not secured with the pins. The pins went through the beam but not the beam tube.

    Again, the parties did not dispute the facts stated in Lacombe’s opinion. And Plaintiffs conceded that “the jury is capable of understanding the concept.” Nevertheless, they argued that the opinion will “aid the jury’s understanding of important parts” of the case. The Court agreed. Lacombe relied on his experience in the swing scaffolding industry to determine and the photographs taken post-accident—showing the beam holes were not “torn or damaged”—to suggest the pins did not penetrate the beam, only the splice tube.

    As such, the Court found Lacombe’s second opinion complied with Rule 702‘s strict requirements.

    c. Lacombe’s Third Opinion

    Lacombe’s third opinion is that:

    OSHA certified training for swing scaffolding does not address specific types of swing scaffolding. There are differences in design in the type of scaffolding that require different assembly. For instance, Spider does not use the exact same design as Sky Climber. One can thus be certified as a competent person but still have to follow manufacturing guidelines and may be unfamiliar with the scaffolding design. Due to differences in design, competent persons assembling and inspecting scaffolding must follow the manufacturer’s warning to ensure proper assembly and safety of the swing stage.

    The crux of why Plaintiffs proffered this testimony is to show that Charles’ employer, FL Crane, had a competent person on site per OSHA regulations and that inadequate warnings led to the accident. This Court’s ruling on Defendant Sky Climber, LLC’s motion for summary judgment, however, found, as a matter of law, that FL Crane did not have a competent person on site. Accordingly, the Court found this argument is moot.

    Held

    The Court granted in part and denied in part Max Access’ Rule 702 motion concerning Brant Lacombe.

    Key Takeaway:

    Lacombe relied on his experience in the swing scaffolding industry to determine and the photographs taken post-accident—showing the beam holes were not “torn or damaged”—to suggest the pins did not penetrate the beam, only the splice tube. 

    This represented “a reliable application” of a “reliable principle” to “sufficient facts” of the case and will “help the trier of fact to understand the evidence or determine a fact in issue”—namely, why the swing scaffolding system failed the way it did.

  • Civil Engineering Expert’s Testimony on Glulam Beams’ Failure Admitted

    Civil Engineering Expert’s Testimony on Glulam Beams’ Failure Admitted

    Defendant D.R. Johnson Lumber Co. is an engineered wood products
    manufacturer located in Riddle, OR. Plaintiff Jasmine Vineyards, Inc. is a grower of table grapes located in Delano, CA.

    Plaintiff asserted a negligence claim against Defendant based on allegations that Defendant “fabricated and/or supplied glulam wood beams in connection with a commercial construction project for Plaintiff” in Kern County, California, to contractors hired by Plaintiff to perform the construction services.

    On May 9, 2025, Plaintiff disclosed to Defendant pursuant to Rule 26(a)(2) its notice of non-retained expert witness and the report of Joseph Engel. Defendant filed a motion to exclude evidence and testimony anticipated to be offered by expert witness Engel.

    Civil Engineering Expert Witness

    Joseph C. Engel has a bachelor’s degrees in civil and mechanical engineering from the University of California at Davis. He has been practicing as a licensed civil and structural engineer for over 40 years.

    As a part of his practice, Engel has designed at least 75 cold storage rooms.

    Discussion by the Court

    Engel is Qualified to Render the Challenged Opinions

    To begin with, Defendant advanced various complaints about Engel’s lack of qualifications, including his lack of employment history in a glulam beam manufacturing plant and his failure to review discovery documents to inform his opinions and conclusions. 

    Engel sought to opine that he observed gaps in the glue between the glulam beams’ lamina and that such gaps resulted in shear stresses that compromised the integrity of the beams. He specifically noted that, “regardless of the reason of the glued joint failure, the evidence of the failure can be clearly seen when the failed beam is carefully examined.” 

    Engel’s degrees in civil and mechanical engineering, his state licensures in civil and structural engineering, his long experience in the field, his experience designing cold storage facilities specifically for table grape storage, including the facility at issue here, and the fact that he has testified at deposition numerous times and recently was qualified in a state court civil case as an expert witness in structural engineering demonstrates sufficient “knowledge, skill, experience, training, or education.”

    Moreover, Engel is not being proffered to render opinions concerning the nature and composition of the glue used in the glulam beams, or to offer opinions about why or how any glue deficiencies occurred. Thus, the Court disagreed with Defendant’s proposition that only a “glue or glue performance” expert could opine about the import of gaps observed in a beam and whether such gaps could compromise a beam. 

    Engel’s Opinions are Relevant and Would Assist the Jury

    In arguing that Engel should be precluded from testifying because his testimony would not assist the jury, Defendant relies on the same argument advanced regarding Engel’s lack of qualifications as a “glue expert” and points out that Engel based his opinions only on his physical observations and moisture testing of the beams, but did not take samples from the beams.

    Otherwise, Defendant did not directly challenge that Engel relied on improper data or applied unreliable principles and methods in rendering his opinions. This is not surprising given that Defendant’s expert witness, Ali Moradi, similarly relied on his physical observations and moisture measurements of the glulam beams to arrive at competing conclusions regarding the cause of the beams’ alleged failure. 

    Given that the parties’ two relevant expert witnesses in this case relied on similar types of data and moisture measurements in forming their opinions and conclusions, the Court found that for purposes of Defendant’s pretrial motion to exclude that Plaintiff has shown it is more likely than not that Engel relied on sufficient facts and data and applied reliable principles and methods in rendering his opinions.

    Defendant’s argument that Engel’s opinions are irrelevant because they do not squarely address whether Defendant breached the applicable standard of care is unpersuasive. Whether or not expert testimony is necessary in this case on the applicable duty of care and breach thereof, Plaintiff must also prove causation to prevail on its negligence cause of action. 

    Held

    The Court denied Defendant D.R. Johnson Lumber Co.’s motion to exclude the evidence and testimony of Joseph Engel.

    Key Takeaway:

    The extent of Engel’s specialized knowledge in the specific field of glulam beam failure goes to the weight afforded to his opinion by the trier of fact, not to its admissibility.
