What is Concrete Tilt-Up Construction
Most warehouses in Southern California are built using the concrete tilt-up (CTU for short) construction technique. This construction style is highly efficient for the construction of medium to large warehouses. Some other fast facts about CTU construction:
City planning departments prefer the look of CTU buildings
CTU buildings are very durable and safe during seismic events
They have long life spans which make them profitable long-term investments
Create the Rebar Cage
Concrete is stiff while metal rebar is flexible. Combining the two creates seismically resilient panels. That's why the first step in CTU construction is to tie steel reinforcing bar together to create a rebar cage.
Form and Pour the Concrete
After the rebar cages are tied, the next step is to create forms. Forms are generally wooden planks that are assembled in such a way around the rebar cages that give shape to the panel once the concrete is poured within.
Tilt the Panels
After allowing time for the concrete panels to solidify, a specialty crane crew will attach cables to engineered 'lift points' on the panels that allow for a safe and balanced hoisting of the several ton panels into the air. The panels will then be carefully guided to their final resting location and attached to the slab and footings.
