Quality Precast Concrete Floor Panels. Structural precast can range from $43 per linear foot for a 15-foot span to as much as $95 per linear foot for a 30-foot span. These are the costs for the material only and won’t include the labor. The necessary fire endurance of concrete building products is determined by the American Society for Testing & Materials (ASTM) E119, defining the procedures and materials needed to create high-quality, fire-resistant building products.

Precast Hollow Core Concrete Planks vs. Composite Slab 5.1 Problem Statement The structure for the Women’s Center and Inpatient Tower is primarily a cast-in-place concrete system; however, part of the structural system is composed of structural steel framing with precast hollow core concrete panels. Cast-in-place, composite concrete topping is highly recommended to provide a smooth, level floor surface that serves as a horizontal diaphragm when properly reinforced. BGC's precast hollowcore planks are manufactured at Australia's most modern precast concrete flooring factory. Here, the average cost can range anywhere from $6 to as much as $15 per square foot. Continuous, interior voids add structural stability, reduce weight and, therefore, reduce cost. technical data.
