61-Story Salesforce Tower Distinguished for its Sustainability

CEMEX, a global building materials company, today announced that Conco Companies, has been awarded a prestigious CEMEX Building Award for its work on Salesforce Tower, San Francisco’s tallest building. Salesforce Tower won first place in the Sustainable Building category in the 2018 International Edition of the CEMEX Building Award during a ceremony Thursday, November 8 in Mexico City.

Salesforce Tower, a 1,070-foot skyscraper completed in 2018, required 110,000 cubic yards of ready-mix concrete from CEMEX to complete its foundation and core interior walls. The building’s mat pour was one of the largest in San Francisco’s history, requiring 18 hours to complete.

“Salesforce Tower is probably one of the most challenging projects we have done,” said Joe Sostaric, Conco’s Corporate Vice President. “CEMEX worked very hard with us. We went through multiple trials, including building mockups, so that we had a mix design to meet all the standards, not only to meet the ultimate strength of 10,000 psi, but also making sure it was placed correctly and had the correct characteristics. We’re proud of what we’ve been able to build.”

Salesforce Tower includes state-of-the-art amenities with low environmental impact, designed for LEED Platinum status. The building includes the usage of recycled water and rainwater as well as the incorporation of natural daylight. Recycled materials were also used where possible. In addition, Salesforce Tower’s design includes innovative power-saving features and 100 percent natural air on all floors.

The first phase in the renovation of the historic LA Memorial Coliseum won the 2018 category of Outstanding Performance in Repair & Restoration for the Southern California chapter of ACI. The Conco Companies was the concrete contractor on the high profile project and has previously been recognized with ACI awards. The project also included general contractor Hathaway Dinwiddie / AECOM-HuntJV; structural engineer Nabih Youssef; and concrete supplier National Ready Mix.

LA Memorial Coliseum Renovation First Phase

Originally constructed in 1923, the LA Coliseum has become an iconic venue from hosting Super Bowls, the Olympics, and numerous other events. The high-profile renovation is being done to update the Coliseum to host the LA Rams and the Olympics in 2028, with an eight-story modern structure with press boxes and luxury suites as well as new lighting, updated audio, Wi-Fi, and video scoreboards.

The first phase of the renovations required Conco’s experience in precision project planning and execution of complex projects. In this renovation, the construction had to work around the 2018-2019 football seasons of the USC Trojans and LA Rams. Phase 1 included demolition, excavation, shoring, concrete placement, and creating the structural steel frame for the 7-story building. The on-grade seating, which included radiused, sloped seating, required special admixtures to meet the project constraints.

Conco’s mission is to be the best supplier of concrete services in the Western United States and to bring experience, expertise and quality to each project. We continue to upgrade and expand facilities to better serve the growing market for public works projects, commercial, educational, parking structures, and other construction development.

Conco is providing a wide range of concrete services for The Asher, a 900,000 sq. ft. multi-family development. This includes concrete pumping, reinforcement, formwork, finishing, construction trucking as well as shotcrete services. Conco is pleased to be working with project developer Carmel Partners. The engineer, CKC Structural Engineers, was also recently recognized with the Concrete Reinforcing Steel Institute 2018 Honors Design and Construction Award for Tower 12 in Seattle. The Asher, situated on a 12.6 acre site, is scheduled to be completed in 2019.

The two, four-story buildings of The Asher will have a total of 632 open floor plan units in Fremont, CA. The wrapped style buildings will feature private patios and balconies with glass or custom wood railings in all units. Each building will also be paired with an above-grade parking structure, totaling 480,000 sq. ft. and 1,200 parking spaces. The South Garage will also feature an 18,000 sq. ft. roof deck on the sixth level, including a pool, bowling alley, and fitness room. The project’s unique shape and orientations includes several landscaped courtyards, effectively creating spaces for smaller communities within the larger development.

The long spans needed in the spacious amenity areas were accommodated by utilizing a concrete post-tensioned slab which was integrated into the light frame structure. This maximized flexibility of the space by minimizing the internal columns needed. The site also had soil issues which were ultimately solved using a shallow foundation system below the parking structure and a post-tension foundation below the residential structure. The two structures have significantly different weights and so it was necessary to balance these foundation systems to minimize differential settlement.

Conco’s goal is to be the top supplier of concrete services in the Western U.S. and to bring our expertise and professionalism to each project. We continue to upgrade and expand our facilities to better serve the growing market for commercial, industrial, educational, parking structure projects and other development. For the best value and quality, trust your project to one of the area’s leading lightweight concrete contractors.

The Conco Companies is providing a full range of concrete services on 1314 Franklin Street. Developed by Carmel Partners, this will be Oakland’s largest residential building ever. For Conco, this project includes concrete pumping, formwork, and finishing as well as construction trucking and shotcrete services.

The 40-story building will be on top of a seven-floor podium totaling 633 residential units and about 17,000 sq. ft. of retail space. Situated across from the historic Oakland Tribune building, Carmel Partners will be giving local businesses a first look at the building’s retail space, and provide between 27 and 54 affordable housing for the project. The unit mix for the residential tower is a single studio apartment, approximately 66% one-bedroom, and 34% two-bedroom units. The unit mix for the residential podium is approximately 9% student, 64% one-bedroom and 27% two-bedroom units.

The tower and podium will sit on a five-story parking garage with two stories below grade. The 404 foot tall residential tower will contain approximately 789,355 sq. ft. gross area with primary frontage and entry along Franklin and 14^th streets. The fourth level rooftop above the parking structure contains a landscaped area, outdoor pool, and associated interior amenity spaces for residents. Level 40 contains interior amenity spaces and exterior landscaped terrace. The rooftop amenity spaces have direct access via a shuttle elevator from level 40 to the rooftop deck amenity area where there will also be a pool.

The space currently is a replacing a two-story parking garage, which has been there for decades, but was once the site of Contra Costa Academy. Founded by Henry Durant, the 16th mayor of Oakland, the academy later became the College of California before it was relocated to Berkeley and became the University of California. A historic marker at the garage will be relocated to the new building when it is completed.

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.

For the 1532 Harrison Street development, Conco is providing a wide range of concrete services including concrete pumping, formwork, finishing, and shotcrete services. The project of three, seven-story buildings connected by a single level below grade parking structure is expected to ready for residents in March 2019. Conco is also excited to partner with BAR Architects and Macy Architecture, who was recently honored with a 2016 AIACC Residential Award. The project’s developer, Build, Inc., was recently named the 2018 Developer To Watch by San Francisco Business Journal.

The three buildings in the West SoMa neighborhood will have 136 mixed-use units, including 22 below market rate units, and will feature two 25-foot wide laneway gardens between the buildings. The underground garage will include 85 parking spaces as well as a dedicated, interior bicycle storage and maintenance area with 137 bicycle parking spaces. Of the ample space available in the buildings, 1,600 sq. ft. of the ground level space will be dedicated to retail and will boast spacious 16’2” tall ceilings. There is also a planned on-site cafe at the corner of 12th Street and Harrison, across from the historic Eagle Tavern.

While the location of the 1532 Harrison Street development has the additional appeal of being across the street from Eagle Plaza, a permanent public plaza and green space, the proximity of this space added complexity to the project for Conco and the architects. Throughout the planning and design process, they aimed to ensure that the green space would be maintained and fit with the new development. The area has been designated a “priority greening opportunity” by local committees, which was incorporated in the design of the generous gardens of the 1532 Harrison Street development. Additionally, the plaza will transform an underutilized street into a well-cared-for green, safe, and clean shared pedestrian way – ideal for relaxing, gathering, and celebrating. During the course of the project, Conco expects to place 4,100 cubic yards of concrete as well as provide shotcrete services as they work to create these new mixed-use residential buildings and green spaces.

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.
