On Monday, February 29, 2016, the Conco Companies topped off the core of the Wilshire Grand Center building in downtown Los Angeles. With over 150,000 cubic yards of concrete poured, and an intensely dedicated crew peaking to over 160 men and women on site, the Conco team has finally reached the milestone to lead the way for the interior finishes.

Once completed, the Wilshire Grand project will be the tallest building west of the Mississippi at a height of 1,099 feet. It will surpass the U.S Bank building, also in downtown Los Angeles, by 81 feet.

The Conco Companies is supplying the entire cast-in-place concrete for this project. This includes:

Record breaking mat foundation of 21,200 cubic yards in a single pour
High strength concrete found inside the core walls
Lightweight deck fill concrete on all floors
Structural deck concrete, below grade walls and columns
Shotcrete perimeter walls

Conco deployed the most powerful concrete stationary pumps in the industry. The primary pump was Conco’s electric powered 14000E pump whose primary benefits are its low carbon footprint and low noise generation. These two significant benefits were crucial in topping off the core, as the pumps were positioned less than 40 feet from an occupied Class A office building. Conco’s 14000E pump is the only one of its kind on the west coast.

Pumping for this project has been trouble-free, allowing us to push both hard rock and lightweight concrete to the top of the structure with power to spare. The 14000E pump has allowed us to move concrete nearly 1,100 feet vertically, and 400 feet horizontally bringing the total pumping distance to nearly 1,500 feet.

Conco has two pumps and supply lines on site to address any unforeseen issues that may arise. The work has been fast-paced with no room for error. The safety of our employees as well as public safety has been our number one priority, and we are proud to announce that the project was a success for both our client and Conco.

The Conco Companies is thankful for a team of dedicated, hard working employees and a great partner, Turner Construction Company. It is with their support and collaborative efforts, that we were able to accomplish this extraordinary feat.

Conco’s extensive scope of responsibilities takes full advantage of our broad range of expertise. For the Santana Row project, we will provide all of the pumping, formwork, reinforcing, stud rail fabrication, post tension, shotcrete, and belting services. In addition we will be employing our Direct Feed capabilities to save time and labor costs.

During the course of the project, we expect to finish 585,000 square feet of concrete as well as pump 26,000 cubic yards of concrete and 2,000 cubic yards of shotcrete. Furthermore, Conco will provide 5,000,000 lbs. of reinforcing steel and 240,000 lbs. of post-tensioning.

On schedule for completion in 2016, the impressive Santana Row Lot 11 offers a variety of amenities with its secure underground parking, proximity to Silicon Valley and the area’s many parks, restaurants, and luxury housing. The project is targeting LEED Gold certification with sustainable features such as the restoration of previously developed areas with native vegetation, a VRV mechanical system designed to achieve a 30% improvement over Title 24 and a high-quality indoor environment.

Well in advance of the building’s scheduled completion, Splunk, a leading data mining company headquartered in San Francisco, signed on to become the tenant. The move will provide Splunk with the opportunity to significantly increase their current Cupertino operations.

The Conco Companies were awarded the complete turn-key structural concrete package for a mixed-use project currently under construction in downtown Bellevue, WA. The nearly two-acre Main Street Gateway complex is funded by Wolff Company. Exxel Pacific, out of Bellingham, WA, is the general contractor. The architect on the project is Baylis Architects, a Seattle based firm.

When finished, the complex at the northwest corner of Main Street and Bellevue Way will have about 350 residential units along with community spaces. At the street level, there will be approximately 14,600 sq. ft. of retail space and another 11,000 sq. ft. of restaurant space. The project includes an underground parking lot that will accommodate about 600 vehicles in addition to several electric vehicle charging stalls. There also will be secure bicycle storage slots available.

Conco brings its vast experience to the project and will provide all of the pumping, place and finish, shotcrete, and formwork. Conco is also supplying the reinforcement that will be installed by RPM. On July 9, 2015, the Conco team poured out the structural slabs well ahead of the project schedule. Tyson Scheenstra, Project Manager for Exxel Pacific wrote:

I wanted to take a second to let you know how appreciative Exxel Pacific is on the Bellevue Gateway project of Conco’s performance. We started with a tough schedule and your team blew that away. On all fronts including paperwork/change orders, shop drawings, procurement, fieldwork and schedule you have knocked it out of the park. Thanks so much! And we look forward to the next project with you.”

Conco took a proactive approach to increasing worker and job-site safety by implementing new procedures including pre-task planning, worker fitness programs and electronic site and equipment inspections. These procedures helped Conco finish this project safely with only one minor recordable incident.

By providing a single source alternative to customers, Conco can supply a project with high-quality, reliable formwork, rebar, place and finish, shotcrete and pumping services all in one place. Conco’s approach of working as a coordinated team allows Conco to anticipate and respond to any problems immediately in order to accommodate customers and to help a project stay on schedule.

The Conco Companies are a leading supplier of concrete services for the Western U.S. We started in the Bay Area in 1959 by offering clients the best value on a wide range of concrete services and products. Since that time, we have taken a leading role as one of the top concrete contractors in the region. We currently serve California, Washington, Oregon, Nevada and Colorado.

The Conco Companies bring vast concrete services experience to the Kinects Tower, a new mixed-use 41-story high-rise under construction in the Denny Triangle area of Seattle, WA. The project is designed by Bumgardner, a Seattle based architectural firm and developed by Security Properties. Once complete, the 500,000 sq. ft. high-rise tower will consist of 356 multi-family units varying from studios to luxury penthouse suites located on the top two floors as well as 4,658 sq. ft. of retail space on the ground level. The completion is scheduled for 2017.

Conco will be constructing four levels of below grade parking and five levels above to provide the building with 316 parking stalls. Working 16 hours straight, we recently completed the 6,000 cubic yard concrete mat pour. Due to our detailed pre-planning and highly experienced management, the pour was a very routine event, which was exactly the result we wanted.

Furthermore, we are proud to report that we received positive feedback from the City of Seattle’s DOT. They have told us this was the best-coordinated and smoothest run mat pour that they can remember. During the course of the project, Conco will place 30,470 cubic yards of concrete, 3,106 tons of rebar and 671,500 ft. of PT cable.

Bumgardner explains that the 440 ft. tall tower was designed to serve as a “highly visible gateway to downtown Seattle, and will reconnect the Capitol Hill neighborhood to downtown with a strong street level presence.” The building’s unique shape of three sides sloping outward means it will have more square footage on the upper levels than below. In addition the Tower will feature a rooftop swimming pool, lounge and observation deck.

The Conco Companies were awarded the concrete contract for a high-end condominium project that is currently under construction in the heart of Pacific Heights in San Francisco. The LuXe is a 34-unit condominium that is being developed by Belrich Partners, LLC and led by the marketing firm of Pillar Capital. Forum Design, an award-winning architectural firm, designed the building with a clean, but warm, modern aesthetic. The general contractor is Centrix Builders and Dolman Consulting Engineers is the structural engineer. The project broke ground in March, 2014 and is scheduled to be finished by the end of 2015.

Just recently the Topping-Off Ceremony was held on March 20th for the 7-story, 73 foot tall building. Conco’s responsibilities on the project are to provide all of the concrete pumping and reinforcement services for the project. In addition we are constructing two subterranean floors that will contain 49 parking spaces for the condo’s residents.

The LuXe will feature elegant, large floor-to-ceiling windows and spectacular views of the city and the surrounding bay. The luxury condominiums’ interiors will be filled with amenities such as wood paneling and designer finishes. Sales for the units will begin sometime this Spring.

The new condominiums are just a small start to help improve San Francisco’s housing shortage. A recent Zillow report shows that the city has granted only 193 new housing units permits for every new 1,000 residents. Paragon Real Estate also indicates much the same thing in their report. It shows San Francisco has had a population growth of more than 45,000 residents since 2010 but has only built 7,500 new housing units.
