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.

Block 216 - The Conco Companies - Portland Commercial Concrete Contractors (8)

Designed by GBD Architects, Block 216 is an area in downtown that was previously only used for parking and street vendors. The structure is a 35-story building with multiple purposes, including a hotel, business space, and residential condo space. It also includes an underground parking garage. There are 4 floors of amenities, including a terrace, restaurant, gym, and bar which will be available to Block 216 residents.

Leadership in Energy and Environmental Design (LEED) has given the project a Gold rating, and the building will be incorporated into the Green Loop of Portland’s Central City. The Green Loop is an effort to connect the areas within Central City through increased mobility by foot, bike, or other mobility devices. The Green Loop requires a 12-foot space behind the property line for buildings near parks.

Block 216 is the largest project in the Portland market within the last ten years. The structure is expected to bring revenue for local businesses in Portland.

Conco started providing concrete services in February of 2020. Services include formwork, reinforcement, pumping, and shotcrete. The project’s main scope is expected to be complete by March 2022.

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.
