Improved tilt-up and precast construction panels and improved methods for creating the same address deficiencies in the current tilt-up and precast construction panels. Improved tilt-up and precast construction panels use less concrete and less steel reinforcement and weigh less than current tilt-up and precast construction panels. Additionally, improved tilt-up and precast construction panels have greater insulative properties (both heat and sound) than do current tilt-up and precast construction panels. Improved tilt-up and precast construction panels require less labor on the construction site, thereby increasing efficiency and profitability of construction crews. Additional advantages of implementations of the invention will become apparent through the following description and by practice of implementations of the invention.

The method for pouring concrete around a window frame begins by spraying a flat surface with a release, followed by positioning window assemblies on the flat surface. The window assemblies include at least a frame, and also possibly a sash, glazing and removable bracing. The window assemblies are secured to the flat surface and then concrete is poured around the window assembly to form a wall. Once the concrete cures around the frame, the bracing is removed, and the wall is tilted/lifted to a vertical position.
