Multiple phase concrete placement mostly takes place on a larger scale. Multiple phase concrete placement is normally used for objects that need to be placed at different times. This can be caused by the object being too difficult to place at once. an example of this could be bridges, or any concrete that has to go overhead. Concrete is very heavy and makes it tough to create forms strong enough to pour in the air and also be able to remove it. Another example of multiple phase concrete placement is housing foundations.

Some dangers of multiple phase concrete placement are: water leakage, weak joints, and planning. Most but not all concrete that is placed in multiple stages is sealed tight and can hold water. An example of this is the Hoover Dam. It was built in many layers of concrete then sealed to be water tight. Another common problem with multiple phase placement is cold joints, this is when the concrete drys and does not completely adhere to itself. This causes the concrete to become weaker on that joint and more likely to break and crack. Finally the planning of a multiple phase placement is the difficulty in planning. It is much harder to plan out an extravagant concrete object than a simple concrete slab.
