SANTA CLARA (KCBS) – It was another milestone day for the construction of the 49ers billion dollar new home in Santa Clara on Monday, with the first concrete being delivered to the site.

Over the next five weeks, a total of 3,000 piles will be drilled at the site.

“Each one of those colored tubes represents where a pile is going to be driven or drilled,” said Tom Albanese with Central Concrete Supply. “They drill down several feet and once they get all the dirt out of it, they’ll slip in a rebar cage. They’ll put the rebar cage in and than they’ll fill it immediately with concrete before it collapses, just in case there’s any loose ground down below.”

KCBS’ Mike Colgan Reports:

Albanese said that by the time they’re done, 80,000 cubic yards of concrete will be poured at the site. To put that in context, that’s enough concrete for 8,000 home foundations.

Project director Jack Hill said they’ve already buried 30 miles of underground utilities.

“In the next 90 days, until August 1, all the work that’s done here will be below grade for the most part,” said Hill. “Around August, mid-August or September, than you’ll start to see the frame going up, like a house.”

Central Concrete has supplied concrete for several projects around the Bay Area, including the NASA Ames Building and San Francisco Academy of Sciences.
