Construction crews at the site of a new hotel and office tower in downtown Los Angeles poured more than 80 million pounds of concrete for nearly 20 hours straight—setting a world record for the largest continuous foundation pour ever.

The team started laying the foundation Saturday (Feb. 15) afternoon for the Wilshire Grand Center—a project that will become the tallest building in the western U.S.—and finished up Sunday morning, according to various reports.  

Crews used 208 trucks and made more than 2,100 trips, ultimately pouring 21,200 cubic yards of concrete, reports said. That is 200 more cubic yards than the previous record set by The Venetian Hotel in Las Vegas. The project was dubbed “the grand pour” via local news outlets.

Construction crews at the downtown Los Angeles site cemented a world record over the weekend.

Following the engineering feat, an official from the Guinness Book of World Records presented the project crew from Turner Construction Company with a plaque honoring the pour. City leaders and developers marked the occasion with a ceremony before the pour began.

Atop the large concrete slab, the $1 billion Wilshire Grand Center, set to open its doors in March 2017, will soar 1,100 feet. The center will replace the longstanding Wilshire Grand Hotel, built in 1952.

Pour Logistics

The tight downtown location posed a challenge for the production, transport and pouring of the concrete, according to the Los Angeles Times.

Eight concrete plants, located no more than 20 miles from downtown, and a backup were used to fill concrete order, the news bureau reported. The trucks had to deliver the concrete within 90 minutes of being mixed.

An official from the Guinness Book of World Records presented the project crew from Turner Construction Company with a plaque honoring the pour.

At the project site, 19 pumps pulled the concrete from the trucks into more than a dozen hoses that crews used to funnel it into the pit, the report said.

"We are proud to be part of the team that planned and achieved the record-setting pour at the Wilshire Grand," said Rich Bach, senior vice president, Turner Construction Company.

Upscale in Downtown

When completed, the upscale project will feature 900 luxury hotel rooms, restaurants, office spaces and nightlife offerings, according to project details provided by developer Korean Air.

The 73-story building was designed by Los Angeles-based architecture firm AC Martin. Chris Martin served as the project architect. AC Martin has designed several landmark buildings in Southern California, including the Los Angeles City Hall in 1928.

Atop the large concrete slab, the $1 billion Wilshire Grand Center will soar 1,100 feet. The center is scheduled to open its doors in March 2017.

Topped with a curved roof and spire that break the traditional flat roof style of most downtown skyscrapers, the developers say the project will exceed the expectations of locals and visitors in the second largest city in the U.S.

A “sky lobby” designed for the 70th floor will provide spectacular views and rooftop dining. In a little over three years, Martin said officials will celebrate the project’s opening in the lobby.

The project is designed to achieve LEED Silver certification, with a special focus on green building techniques and materials.

At the project site, 19 pumps pulled the concrete from the trucks into more than a dozen hoses that crews used to funnel it into the pit, the report said.

In a statement on the design, L.A. City Council member José Huizar said the project “represents a new chapter of world-class architecture gracing Los Angeles’ skyline—this iconic design will be a model for future high-rise buildings in downtown.”
