Columbus v. Smith & Mahoney, P. C.Columbus v. Smith & Mahoney, P. C.
Appeals (1) from a judgment of the Supreme Court (Canfield, J.), entered February 6, 1998 in Albany County, upon a verdict rendered in favor of plaintiffs, and (2) from an order of said court, entered March 10, 1998 in Albany County, which denied a motion by defendant Smith & Mahoney, P. C. to set aside the verdict.
While employed by the City of Albany, plaintiff Robert Columbus (hereinafter plaintiff) was injured when he fell approximately 12 feet from the top of a salt spreader which weighed approximately 2,100 pounds. The accident occurred when plaintiff was attempting to store the spreader on wooden hangers suspended from the ceiling of the City garage. The storage system, which was designed by defendant Smith & Mahoney, P. C. (hereinafter Smith) and constructed by defendant D.J. Contractors (hereinafter D.J.), consisted of cables attached to steel plates which were bolted to wooden 2 x 8s supported by metal braces affixed to the ceiling. The spreader was hoisted by come-alongs and the cables were attached to each of its four corners. The accident occurred when one of the 2 x 8s fractured along the grain of a large knot causing that part of the board supporting the metal plate and cable to give way.
Smith contends that plaintiffs failed to adduce proof establishing a prima facie case of negligence and/or malpractice in the design of the storage system and, therefore, Supreme Court erred in denying its motions for a directed verdict and an order setting aside the verdict. Based upon our review of the record, we agree. It is well settled that in order to prove negligence or malpractice in the design of a structure, the plaintiff must put forth expert testimony that the engineer or architect deviated from accepted industry standards (see, Interstate Cigar Co. v Dynaire Corp.,
Paul Montgomery, a structural engineer produced by Smith as an expert, testified that number two grade lumber of the type specified by Smith was the most common type of wood used in the construction industry and was acceptable for hanging loads notwithstanding the presence of knots. He reviewed the calculations of Paul Koch, the engineer formerly employed by Smith who drafted the design specifications. He stated that Koch took into account a significant safety factor in calculating the load on the wooden members comprising the storage system and also consulted the Building Code which incorporates standards published in the National Design Specifications (hereinafter NDS) and the American Society of Testing Materials (hereinafter ASTM) in ascertaining the grade of lumber ap
Vito Colangelo, a metallurgist who testified as plaintiffs’ expert, stated that the presence of a knot inherently weakens wood due to its disruption of the longitudinal fibers in the area immediately surrounding it and that, in his opinion, the use of number two grade lumber was inappropriate for the storage system because it contained knots. He did not, however, state that Smith’s specification of such lumber deviated from acceptable industry standards. To the contrary, he agreed that Koch’s calculations, which reflected a substantial safety factor, were correct and that the NDS and ASTM establish legitimate industry standards that take into account the presence of knots in grading the stress levels of different types of wood.
Viewing the evidence in the light most favorable to plaintiffs (see, Tucker v Elimelech,
Mercure, Spain, Carpinello and Graffeo, JJ., concur. Ordered that the judgment is modified, on the law, with costs to defendant Smith & Mahoney, P. C., by reversing so much of the verdict as found defendant Smith & Mahoney, P. C. 45% liable for plaintiffs’ injuries; and, as so modified, affirmed. Ordered that the order is reversed, on the law, motion granted and complaint dismissed against defendant Smith & Mahoney, P. C.
