Aerial Photos: Kaiser Trucks Dump First Loads of Concrete

More than 140 cement trucks gathered at the crack of dawn Wednesday morning to continue to lay the foundation for 's . 

Nov. 9 was one of four "Big Pours"; the next pour will be Nov. 19 and another is tentatively scheduled for Dec. 1 or 3. The 7 story hospital is slated to be finished by 2014.

It's a carefully-choregraphed construction job using concrete pumpers and long booms, according to spokesperson Karl Sonkin. 

The mat foundation anchors the new structure to the ground and helps it resist ground movement.  Steel beams for the new structure itself are expected to start rising in early December.  

From the top level of the parking garage behind 901 Marshall Street, residents can see 1,450 cubic yards of concrete (more than 5-million pounds of concrete for this one section alone) being pumped into forms filled with intricately-laced steel reinforcing bars.

If you repurposed all of the steel reinforcing bars in this entire foundation project you could build more than a thousand automobiles, and the total concrete for the entire mat foundation could build nearly 30 miles of standard sidewalk in Redwood City.

After the concrete dries, 9,000- tons of rock will go on top of the four sections and another slab of concrete will be poured to become the hospital's ground floor.
