Saturday, August 24th was not your typical day for Conco.  While many projects are shutdown for the weekend, this Saturday was one of the busiest Saturdays in Conco’s 60-year history.

The activity began Friday evening in Southern California.  Starting at 9:30 PM, Conco began to pump, place, and finish 10,400 cubic yards in downtown Los Angeles on a project known as The Grand.  The Grand is a mixed-use project with retail, residential and a hotel across the street from the Disney Concert Hall.  The developers for The Grand are The Related Cos. and CORE USA for this Frank Gehry designed structure.

The Grand Concrete Pour

The Grand 10,400 concrete pour was the second of three foundation pours for the structure. Eight concrete pumps were positioned around the foundation to receive concrete at the scheduled delivery rate of 750 cubic yards per hour.  In order to supply concrete at this rate, Calportland, with the assistance of Associated Concrete, utilized five batch plants and over 120 concrete mixer trucks.

 

In addition to the work performed on The Grand, Conco had another large concrete pour on this day in downtown Oakland, CA.  Working for the Holland Partner Group, the project located at 24th & Harrison, site of the old Acura dealership, will comprise of luxury apartments with retail and other amenities.

Before placing the concrete, Conco was responsible for fabricating and installing all the rebar.  Comprised of mainly #11 bar, more than 4.1 million pounds were needed for the entire mat foundation.

24th & Harrison Concrete Pour

The 24th & Harrison project by the Holland Group was the second of two foundation pours at the site, requiring 7,300 cubic yards of concrete supplied by Central Concrete out of five concrete batch plants. Prior to pouring the concrete, Conco provided the fabricated rebar and installation. The challenging site necessitated that six concrete pumps (five were active at any given time) be used with a scheduled delivery rate of 600 cubic yards per hour being delivered by 120 concrete mixer trucks.  The concrete pour began at 1:00 AM.

950 Market Street Concrete Pour

Furthermore, in addition to the Los Angeles and Oakland pours, a mat foundation pour also took place simultaneously in San Francisco, CA.  The project at 950 Market Street will be a mixed-use development consisting of housing, a hotel, retail, and a dedicated non-profit space.  This project is being developed by Group i, a San Francisco-based real estate development company.  Working for the general contractor, Pankow Builders, Conco also fabricated and installed the rebar for the foundation.  More than 1.7 million pounds were needed to be put in place prior to concrete placement for the entire foundation.

The mat pour for the 950 Market Street project was the first of two for the site and was supplied by CEMEX out of three concrete plants. A total of 3,195 yards of concrete was pumped, placed and finished by Conco through three concrete pumps that were supplied at a scheduled rate of 300 cubic yards per hour.

For the activity in three separate markets to transpire, multiple internal and external meetings were held to discuss every facet of activity associated with making each concrete pour a success.  For Conco, success comes from developing the proper plan and executing that plan.  Items such as safety, concrete mix designs, pump placement, street closures, individual company responsibilities, and contingencies are just a few of the details that must seamlessly be ironed out.

The resources that were used and vital statistics for Saturday, August 24, 2019 were:

The Grand
Los Angeles
24 & Harrison
Oakland
950 Market
San Francisco
Total
Concrete Placed 10,400 7,300 3,195 20,895
Concrete YPH Placed 750 600 300 1,650
Square Feet Finished 41,000 44,800 18,000 103,800
Mixer Trucks Used 120 140 60 220

With the combined effort of Conco, our customers and suppliers, all three projects finished on time with only 5 extra yards of concrete for all three projects combined.   More importantly, all were completed without so much as a first aid claim.

Large mat foundation pours require extensive planning and collaboration with customers, suppliers, public agencies and various other third parties.  Conco’s success is dependent on everyone doing their part and we at Conco are thankful to work with great customers and suppliers day in and day out, who give us the opportunity to succeed.

The Marriott Hotel is slated to open a new franchise, the Moxy Hotel in Portland, in the Pearl District in summer of 2020. Construction began in June 2019 on the new project and promises to bring a unique, contemporary take on the hotel experience to the lively neighborhood in downtown Portland. Several notable groups have come together to develop and execute the project, including development company Graves Hospitality, DLR Group Architecture, and Portland commercial concrete contractors The Conco Companies.

A Franchise for the Young and Young-at-Heart

As a new franchise from the well-known Marriott Hotel, the Moxy Hotel is looking to attract a new sector of hotel guests. The stylish interiors, contemporary designs, and vibrant urban locations are being offered at an affordable price for leisure travelers and business professionals alike. With the vision of immersing guests in the cityscape around them while providing smart, modern accommodations, the Moxy Hotel boasts several unique features.

9) Block 4 Indigo Tower Complete

Seattle commercial concrete contractors, The Conco Companies, is working with Kirkland Developers, Kirkland Construction Group, and OTAK Architects to bring an immense and exciting new project to The Waterfront Vancouver development.

An Evolution by the Riverside

The waterfront district in downtown Vancouver, Washington has taken many shapes during its lifetime. Once a hub of lumber mills and shipping depots in the 19th century, then a set of shipyards in the early and mid-20th century that produced ships for World Wars I and II, and lastly the home to a paper mill that closed in the 1990s – this industrial area next to the Columbia River has undergone many iterations. None, however, have been quite as dramatic a shift as the district’s newest conception: The Waterfront Vancouver. The Waterfront Vancouver is a massive redevelopment and revitalization project that has turned this industrial area into a bustling mixed-use development that includes residential, commercial, and retail space.

Among the many new buildings rising along the river are Hotel Indigo and Kirkland Tower, the largest project to date in the development. The $100 million project includes not only the four-star, eight-story hotel and the 12-story residential tower with condominiums, but also 17,000 square feet of retail space and multiple high-end dining facilities. Hotel Indigo boasts luxe amenities such as concierge services, valet, dry cleaning, and a dog-washing station, while Kirkland Tower will feature one-, two-, and three-bedroom condos, where residents can also utilize the amenities of the hotel.

Comprehensive Concrete Services for a Large-Scale Project

To begin construction on the project, the Conco Companies provided a 33,357 square foot concrete mat foundation ranging in thickness from four feet to just under six feet and designed to contend with the high water table at the waterfront. In addition to the foundation, Conco will also provide two concrete stair cores and an elevator core, as well as the decks. With the target top-out date of mid-December 2019, Conco is completing one deck pour every 4-5 days, with each deck up to the eighth level requiring three pours to finish. Altogether, Conco will provide the concrete pumping and finishing, concrete reinforcement, concrete formwork, and shotcrete services for the massive project.

The Conco Companies’ mission is to be the best supplier of concrete services in the Western U.S. and to bring expertise and incomparable quality to each project. We continue to upgrade and expand our facilities to better serve the growing market for commercial, educational, parking structures, public works projects, and other development.

Grand-Project-LA-Mat-pour-video-The-Conco-Companies.jpg

The Grand is an immense, much anticipated mixed-use development project in the Los Angeles neighborhood of Bunker Hill that commenced construction in May 2019. To kick off the project, Los Angeles commercial concrete contractors, The Conco Companies delivered an impressive demonstration of its skills and expertise. For the first of the two towers to be erected for the project, Conco provided the second-largest continuous casting of a foundation in Los Angeles in a mere 15 hours. The project with the top honors in this category and the recipient of Guinness World Record recognition in 2014 was the Wilshire Grand Center, also completed by Conco.

The metrics for the foundation mat pour of this 39-story residential tower designed by Frank Gehry are staggering: 140 skilled Conco employees placed 13,275 cubic yards of concrete at an approximate rate of 1,000 cubic yards per hour. The 39,303 square foot concrete mat varies in thickness from 6 feet to 12 feet and weighs roughly 27,000 tons. Throughout the 15-hour mat pour, eight state-of-the-art concrete pumps worked to pump and place the concrete while 1,348 truck trips to six batch plants were completed.


In addition to the speed of its service delivery and the seamless coordination with multiple stakeholders such as developer Related Companies, the Los Angeles City Council, and the Department of Transportation, Conco also achieved the feat of zero injuries during this first phase of the project. Conco prides itself on prioritizing job site safety, and true to Conco’s focus, despite the dizzying speed of the mat pour, there were no injuries. The experience and expertise behind Conco’s reputation as the top supplier of commercial concrete services – no matter the scale or difficulty of the project – was certainly on full display during this massive mat pour.
