Sea-Tac Update -The Conco Companies

Conco is teaming up once again with Clark Construction. Conco’s Northwest division is returning to Seattle-Tacoma (Sea-Tac) Airport to provide concrete services for the LEED Silver International Arrivals Facility (IAF) building on the east side of the South Terminal Expansion (Concourse A). The new Arrivals Facility will help the airport manage the increasing demand for international flights. The IAF will host gates A3-A14 in an elevated sterile corridor, raised nearly 32 feet above the apron level, with approximately 45,000 square feet of floor space.

In addition to the overall 450,000 Sq. Ft. of the IAF, the project also includes a 900 ft long aerial passing over the existing taxi lane at a height of 85 feet (allowing planes to travel beneath), to connect arriving international passengers at the South Satellite Terminal to the top of Concourse A and the new space. The bridge components will be prefabricated off-site and installed within a seven-day time frame. The construction activities are taking place in an active area of the airport, requiring an additional level of coordination – and patience- for all involved. Upcoming project milestones include:

PW-1 Concourse A Concrete Core Bridge Support Completion
IAF Slab on Grade Completion
PW-4 South Satelite Concrete Core Bridge Support Completion

Tacoma Convention Center Hotel Update - The Conco Companies

“This estimated $150 million hotel and mixed-use project will contribute to downtown Tacoma’s renaissance significantly,” according to a city staff report. “It is one of the first major foreign direct investments on publicly owned land in Tacoma. The project will generate substantial tax revenue, create about 1,000 construction jobs and at least 200 full-time jobs, and enable the GTCC to attract larger conventions to enhance Tacoma’s economic vitality.”

The Tacoma Convention Center Hotel, developed by Yareton Investment & Management, will offer 300 rooms in a new Mariott branded hotel and retail spaces. Expected to open in 2020, the 4-star hotel will rise 23 stories, include 304 guest rooms, and will be connected to the Greater Tacoma Convention Center. It will also feature a 10,000 square foot grand ballroom, retail space, and other function rooms. The hotel will serve as the anchor hotel for the convention center, which has struggled recently to land larger convention and trade shows because of the lack of nearby hotel rooms.

The Conco Companies NW Division is working a 7-day cycle in the tower, pouring the vertical the same day as the slab is poured, with a self-climbing core form system (supplied by FCI). The tower portion, consisting of the hotel, continues to L23 + a cantilevered concrete roof. The project will utilize 5,550,000 lbs. of rebar, 25,000 cubic yards of concrete, and 430,000 linear feet of post tension cables. Conco is scheduled to pour-out the project by June 2019.

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.

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 CEMEX Building Award recognizes industry leaders, and Conco Companies is a strong example of one,” said Marsat Lal Mirpuri, CEMEX USA’s VP/GM Ready-Mix Bay Area. “We’re proud to have worked with Conco on such an exemplary achievement, reshaping the San Francisco skyline with an iconic project that will stand for years to come.”

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.

the asher

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.
