Wilshire Grand Concrete Pour Sets Record

Posted: Updated:

(FOX 11 /CNS) - A construction crew concluded its record-setting
foundation pour of 21,200 cubic yards of concrete today, and laid the
foundation for the 73-story hotel and office tower that will be built there.

A representative from Guinness World Record officially made the
announcement at 11:15 a.m., the time the feat was completed, said Sean Rossall,
spokesman for Korean Air, the project's developer.

"I'm tired," said Michael Marchesano, General Supervisor for Turner
Construction. "I'm actually thrilled we got through this and that no one was
hurt -- not one person. I'm very proud of our safety and coordination.'

Starting just before 5 p.m. Saturday, crews began what would be a
Guinness World Record by continuously pouring about 21,200 cubic yards of
concrete into the massive pit on Wilshire Boulevard, between Figueroa and
Seventh streets.

The concrete, weighing about 82 million pounds, was delivered by 208
trucks making 2,120 trips.

Rossall said the previous record was 21,000 cubic yards of concrete, set
by the foundation pour for the Venetian hotel and casino in Las Vegas.   

The Los Angeles pour went so well, exceeding an earlier, scheduled
completion time of 10 p.m. tonight, he said.

Spectators watched the pour from the sidewalk at Figueroa Street and
Wilshire Boulevard.

Sections of Figueroa Street, Seventh Street, Wilshire Boulevard and
Francisco Street were closed during the pour.

Concrete foundation pours can also done in phases, but the continuous
session is thought to result in a more structurally sound foundation, as well
as being less costly, Rossall said.

"We didn't set out to make a record, it just happened. It ended up
being more efficient," he said.

Cold water piped in through several tubes embedded in the foundation
will absorb heat from the curing concrete and help the hardening process, which
is expected to take two weeks, he said.

"The cooler the better," Rossall said, noting crews hope for cooler
temperatures in Los Angeles to speed up the curing process.

The $1 billion Wilshire Grand project includes office space,
restaurants, retail and 900 luxury hotel rooms.

Topped by a 100-foot spire, the building is expected to be the tallest
west of Chicago once it is completed in 2016.

The USC Trojans marching band paraded ahead of the first few concrete
trucks before the start of the pour, which was marked with a ceremony attended
by Los Angeles area dignitaries, including Mayor Eric Garcetti. Korean Air's
CEO Yang-ho Cho was also on hand to oversee the event.
