Concrete Finishers Archives | The Conco Companies

The Conco Companies is providing concrete services on the Alta Burnside project in downtown Portland, Oregon. During construction, services include concrete pumping, reinforcement, formwork, and shotcrete.

Located at 1638 W Burnside St, this 154,480 sq foot mixed-use building is being constructed by Pavilion Construction under the direction of Wood Partners. Alta Burnside includes 6,000 square feet of retail on the first floor, 138 residential units, and an underground parking garage. Add the wraparound terrace to its predominantly glass and brick walls, and you will see that this is an impressive building. Best of all, it is in a popular Portland neighborhood near the Providence Park Stadium.

Construction began in July 2018, and presented a unique challenge. The footprint of Alta Burnside was originally occupied by other buildings. Architect Ankrom Moisan had the unique challenge of designing a building to fit into this tight space. Conco, in turn, had to work very carefully with the excavation contractor to ensure scheduling constraints were met.

Conco worked with KPFF Consulting Engineers to select the correct concrete chemistry and specifications during the planning period. As commercial concrete contractors servicing Portland & Southern Washington, Conco is proud to have participated in this urban renewal project.

Conco is one of the foremost suppliers of concrete pumping services for the Western U.S. We got our start in 1959 in the Bay Area by offering clients the best value on a broad range of concrete services and products. Since that time, we have taken a leading role as top concrete contractors in the Western region. We have regional offices serving California, Oregon, Nevada, and Washington.

Completed Concrete Renovations Los Angeles Memorial Coliseum - The Conco Companies -

The Conco Companies recently completed all structural concrete renovations for the LA Memorial Coliseum Renovation Project. Conco’s services included finishing, formwork, pumping, and shotcrete.

The Los Angeles Memorial Coliseum underwent the largest renovation in its 100-year history. Newly named, United Airlines Field at the Los Angeles Memorial Coliseum, the $315 million makeover will host the University of Southern California (USC) Trojans, LA Rams football teams and prepare for the 2028 Olympic Games in Los Angeles.

The Conco Companies placed approximately 24,000 cubic yards of concrete, including mat foundations, slab over metal decks, structural decks, shotcrete and new concrete seating in a large portion of the stadium bowl.

The whole north and south concrete seating bowl was replaced in order to add wider seats, more legroom, and extra aisles. Additionally, an eight-story structure was built to house new press boxes and luxury suites. A specially designed concrete mix was poured to protect reinforcing. This was necessary due to the concrete exposure to the environment. Concrete Admixtures were used for corrosion inhibitors and waterproofing.

Like every high-profile project, the Los Angeles Memorial Coliseum presented its own challenges. Conco’s planning and execution skills were tested by some of these challenges, such as:

Swiftly installing high quality, unique formwork systems with tight radius and slope seating.
Rigorous schedules to perform the work without impacting the 2018-2019 football season of both USC Trojans and LA Rams.

The Conco Companies was selected based on our vast stadium experience and multiple concrete services. Conco successfully completed the job on schedule and meeting the client’s expectations.

Epic Tower Project Update - The Conco Companies

The Conco Companies topped off the new mid-rise Epic Tower in February 2019. Conco provided all cast-in-place concrete services, including finishing, formwork, pumping and shotcrete.

Developed by Hudson Pacific Properties and designed Gensler Architects and Nabih Yousef and Associates, the project, under Hathaway Dinwiddie features a 14-story tower with 300,000 square feet of office space, 18,400 square feet of new retail space, and 5 levels of structured parking. The $150 million-dollar development will be an expansion to the Sunset Bronson Studios Complex directly across the street.

The unique building includes terraces at every level with modern appearance landscapes, providing a seamless transition to outside workspaces through tall glass walls that overlook the city of Los Angeles. Office space features new 15-foot lower profile ceilings with open floorplans.

The project started in December 2017 and presented logistic challenges due to its location, high volume of traffic, and limited site access. Epic Tower took nearly 43,000 cubic yards (cy) of concrete to be completed. A total of 11,000 cy was poured on footings and 12-foot mat slabs surrounding the concrete core. The methods used to place mass concrete had to be taken into consideration with thermal control plans. Vertical elements on the structure such as columns and the concrete core tower required a 7,000 PSI and a high modulus of elasticity (MOE).

To overcome these challenges, Catalina Pacific provided a mix design using Orca rock and provided a mix that would reach nearly 9,000 PSI at 56 days. The concrete decks which comprised 50% of the overall yardage of the project, also had high requirements on MOE and Orca rock with a 6,000 PSI requirement. Additional challenges included a 10-foot cantilever deck, which was completed successfully by our formwork team.

Conco was selected for this project because of our experience and commitment to high-quality planning and execution on complex projects.

Boren Tower - The Conco Companies - Seattle Concrete Contractors 4 (1)

Boren Avenue is known for the cultural and pedestrian experience that it brings to Seattle residents and visitors. It is home to Cornish College’s famed Raisbeck Hall on Boren, among other notable historic sites. The challenge for Holland Residential and The Conco Companies, was to design and build a structure that reflects Seattle’s modern skyline without jarring the existing buildings. The result was a design that everyone can agree on.

Holland Residential’s new project, Boren Tower, is underway after receiving unanimous approval of their latest design. The tower replaces three surface-level parking lots totaling 21,600 square feet on the corner of Lenora Street and Boren Avenue. Designed by the Seattle architectural firm, Weber Thompson, the 44-story mixed-use tower will accommodate residential, arts, and office spaces at 2019 Boren Avenue. It also offers below-grade parking for over 360 vehicles.

Residential amenities include both outdoor and indoor space on level 5, atop the tower’s roof, and on the podium level. The south terrace provides a pool deck, cooking/hospitality area, and a full, wrap-around bar. Although floor plans and per-unit square footage are still in the works, upper floors will contain 400 residential units, with four penthouses on level 42 and 43. The entire project will total 643,000 square feet.

The Conco Companies poured a mat slab in January 2020, consisting of a monolithic base mat pour of 5,920cy. with an additional upper mat slab pour of 730cy. The crew utilized three pumps to pour the concrete. Cadman supplied the readymix, averaging 348 yards per hour for the pour, with a maximum output of 463cy per hour. Conco Reinforcing supplied over 1.5 million pounds of rebar for the mat, installed by RPM.

The Conco Companies is partnering with Holland Residential throughout the planning and execution phases of the project due to our solid working relationship, reliable services, and competitive bids. This is our fourth tower project with Holland. The scope of the work will include concrete pumping, finishing, reinforcement, formwork, trucking, and shotcrete. The project is expected to be completed by August 2021.

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. The 197 guest rooms will offer views of the city and Mt. Hood through floor-to-ceiling glass walls in their corridors, while the hotel’s public spaces will offer a range of sought-after amenities. The Moxy Hotel promises an open and engaging ground floor space that is designed to draw guests out into the surrounding city. The space will feature large operable glass walls, a full-service bar and lounge area, game rooms, and food carts. Additionally, the exterior is designed with deep canopies extending over the sidewalk for food cart goers to enjoy the offerings no matter the weather.

A Challenging Site for The Moxy Hotel

This exciting project is not only unique in its vision, but also in its dimensions. Situated on less than a quarter of a block, the 12-story hotel has a dainty building footprint. Benjamin Graves, the president and CEO of Graves Hospitality said of the project, “We’re creating an amazing addition to this neighborhood by defying the unthinkable and building 71,232 square feet of ground-up construction on an incredibly compact 7,500 square foot site.” In order to overcome this challenge of construction, the Conco Companies was brought on to provide an array of concrete services.
