Notice the different level in height between the restrooms and the main floor of the library. The main floor will rise to the height of the restrooms, once the electric wiring, ducts, and heating are in place.
Notice the front tires of the Cement Pump truck are not touching the ground?
Notice the Concrete Pump truck is being held up by these Outriggers?
Each cubic yard of concrete weighs approximately 3500 pounds. When it flows through the pump, the weight of the concrete is enough to pop the tires or tip the concrete pump on its side. As a safety measure they use the outriggers to prop the pump up and avoid catastrophe.
Notice the height level difference between the main rooms and the Computer and Restrooms. Eventually, they will all be the same once the wiring and new flooring materials are installed in the main rooms.
During the construction of the new Ortega branch, our temporary site (Mini-Ortega) will be open for business. We are located inside the West Sunset Park and next to the construction site.
