A tilt-up is a type of concrete building that sounds a lot like its name. It's a concrete building that is literally created by tilting-up concrete panels. A tilt-up is formed in five basic steps.
1. The footings - Like any other building, a tilt-up requires footings. Several footings will be dug, formed and poured in order to create a foundation for the building.
2. The slab - After the footings are poured, the next step is pouring the slab. The slab is the concrete floor that serves as the floor of the building.
3. The panels - Tilt-ups are made of concrete panels. Concrete panels are laid out and formed on top of the slab. The panels are what will be the future walls of the building. Each wall is formed on the slab. Once the walls are formed, concrete is poured inside of the formed panel.
After the concrete is poured and dried, the panels will be ready to be hoisted into the air and will become the walls of the building.

4. The tilt-up - When the panels are ready, a crane comes and hoists up each of the concrete panels creating the walls of the building. The walls are literally tilted-up with the crane, hence where the name tilt-up comes form.
5. Joists and deck - After the concrete panels are tilted-up and in the air, the joists and deck and structural steel are erected. Structural steel columns are fastened to steel plates tied to the footings of the building. These steel columns work in unison with the joists going through the building to hold the building together. These joists and columns also hold metal deck to act as the roof of the building. Roofing membrane goes on top of the deck to waterproof and insulate the building from the outside elements.
