The completion of the $50 million campus for Kubota Tractor Corp in Grapevine has pushed the vertical limit of tilt-wall construction, with its tallest concrete panel coming in at 82 ft 11 in. In the past, tilt-wall construction has been reserved for mainly industrial buildings, but as technology has evolved — so has the use of tilt-wall construction — and it has fully transferred into the construction of office buildings. The building appears to be four-stories tall instead of its actual three story height and has 20-foot floor-to-floor heights. A 300-ton crane was used to erect the concrete walls.
