Opinion

Phipps, Judge.

This case arose from a wrongful death action filed by the estate of Viktorya Vaynshteyn 1 against Tensar Earth Technologies, Inc. and its parent company, the Tensar Corporation (collectively Tensar Companies), the City of Atlanta (City), and several other defendants. All defendants except the Tensar Companies settled. In 1996, a trial was held on the estate’s claims against the Tensar Companies and on a cross-claim asserted by the City against the Tensar Companies for contribution. A jury found in favor of the Tensar Companies, but the court granted a new trial. The Tensar Companies settled with the estate, and in 1997, the case proceeded on the City’s contribution claim. The City asserted that the Tensar Companies were liable to the estate under theories of negligence and products liability. The Tensar Companies were denied summary judgment, and the case went to trial. A jury found in favor of the City, and the trial court entered judgment on the jury’s verdict and then calculated an award for the City.

All parties appeal. The Tensar Companies’ appeal, Case No. A03A1938, and the City’s cross-appeal, Case No. A03A1939, are consolidated in this opinion. Because the record demonstrates that the trial court erroneously excluded evidence and deprived the Tensar Companies of one of its defenses, in Case No. A03A1938, we reverse the judgment entered upon the jury’s verdict, vacate the City’s award, and remand the case for proceedings not inconsistent with this opinion. We dismiss Case No. A03A1939, as that case appeals the City’s award.

The following evidence was adduced at trial. In 1988, Marriott Hotels, Inc. hired Sain South, a civil engineering firm, to provide site designs for a Marriott Courtyard hotel that it was planning to construct on 14th Street in Atlanta. Sain discovered that a combined sanitary and storm sewer, approximately 11 feet in diameter, crossed underneath a section of the property. Because of concerns about the structural integrity of that portion of the sewer, Marriott and Sain agreed that a reinforcing safety net (geogrid) would be installed in the soil above the sewer and below what would become the hotel parking lot. Mark Gonzalez, then a Sain project manager on the project, testified, “the geogrid safety net was to support the parking lot for a period of time should some void . . . below the parking lot open up, *46 creating a lack of soil support beneath the parking lot or the area that ... was [ajffected.” And if a void developed, Gonzalez explained, there would be “significant deflections in the parking lot curb, movement of retaining wall, things of that nature which would express themselves at the surface.” The completed Sain site drawings incorporated the use of a geogrid.

Eobert Anderson, a professional geo-technical engineer employed by Tensar Earth Technologies, testified that around January 1990, he was asked “by our sales organization” to “provide an alternative design to this so-called safety net” contemplated by the Sain site drawings. He had known that there were concerns about the structural integrity of the sewer and that the sewer’s diameter was approximately 11 or 12 feet. Anderson had understood that purposes of a geogrid included: “to bridge or span some void for some amount of period of time to allow the authorities, be they the Marriott or whoever, to have adequate notice to barricade off the area and then go in and repair it because ■— serve warning of a problem” and “to hold up the parking lot if the sewer collapsed.” He had envisioned a “collapse” as either a “complete structural cave-in of the sewer, or voids building up and the soil above or around the sewer eventually enlarging to some point where the surface would then tend to collapse. Not necessarily that the masonry and the sewer all came crashing down.”

Anderson and others at his company designed a geogrid. Anderson testified that a critical step in designing the geogrid was estimating the size to which a void might grow. And that estimation was made by him. He used a void size of 20 feet in his calculation, assuming that size was a reasonable estimate. He explained that in case of “an instantaneous collapse that’s exactly 20 feet in diameter and is a perfect circle,” the geogrid would support the parking lot for about four days while the parking lot increasingly sagged to about four feet during that time.

Tensar submitted its initial design for a geogrid and was asked to cut its price. The product was made less expensive by adding various “efficiencies” in the design. Anderson explained, “At the time of the original design, I had two pieces of paper which gave me an idea of... a competitive design shown on the plans, what it was all about.” By the time Tensar was asked to cut its price, Anderson testified, “I could do a proper design, and that proper design was a far more efficient use of grid than I had assumed on the original design so I was able to use less grid.” In addition, the second version was designed to support less weight than the initial version. After Tensar answered various technical questions from Sain, Sain approved the use of Tensar’s geogrid in the project. The end product was referred to as the Tensar *47 Geogrid. Safety Net (Tensar Geogrid). In 1990, 3-D Excavators, Inc. installed the Tensar Geogrid into the soil. Construction of the hotel was completed.

In May 1993, Gary Grantham, a Marriott Courtyard engineering manager, noticed that cracks had developed in the parking lot and in the retaining wall of the parking lot and that a stairway leading from the first level of the parking lot to its second level had begun separating from its support wall. He also saw concrete “spalling off or near an expansion joint of the lower end of the retaining wall.” At that time, Grantham was unaware of the underlying sewer and geogrid.

On June 10,1993, Grantham saw other conditions in the parking lot. The stairway had separated farther from its support wall; the cracks in the parking lot were larger; a manhole had “pull[ed] away rather significantly from its surrounding asphalt”; and a depression of three to six feet had developed in the parking lot. That day, Grantham met with a project manager of 3-D Excavators, who told him that a sewer ran under the property, that it was old, and that reinforcement had been installed in the soil to work as a “bridge” to support the parking lot in case of a problem with the sewer. The project manager entered the sewer, inspected it, and then informed Grantham that there might be some problems with the sewer and that he should call the City, which Grantham did.

That same day, Tyler Kane and James Walker, City employees, entered the sewer to inspect it. Kane determined that the sewer needed “emergency repair.” He contacted a contractor, who could not come to the site until the following Monday, June 14. Kane “thought that would be okay.” Walker also concluded, based on his observations, that the situation with the sewer was “an emergency.” In a memorandum, dated June 11, 1993, to the Coordinator of the City’s Contracts, Grants & Assessments Department requesting monies for the repair, Walker stated, “[t]he present condition of this sewer may lead to an immediate and total collapse of the structure from 14th Street south to the Marriott parking lot.” Meanwhile, Grantham barricaded areas of the parking lot as suggested by a City employee, as well as some extra parking areas.
