Center Steps Project - The Conco Companies - mat pour (2)

The Conco Companies is providing concrete services for the Center Steps project in Seattle, Washington. Located in the shadow of the Space Needle and across the street from major arts venues including McCaw Hall, the Pacific Northwest Ballet, Cornish Playhouse and Seattle Repertory Theatre, Center Steps is part of a bustling new community bridging Seattle Center from residential uptown. The location provides a walkable commute to major employers including Amazon, the Bill & Melinda Gates Foundation, and Facebook.

The site will have two mixed-used buildings, one with eight stories (83 units) and the other with seven stories (186 units), and 11,239 sq. ft. of retail space. The L-shaped development will include a 6,000 sq.ft. public plaza with a pedestrian pathway between the two buildings. The concrete scope of the project consists of two below-grade parking levels with parking for 182 vehicles, a retail and commercial space with an extensive courtyard at ground level, and three concrete levels of residential above-grade with wood framing to the 8th story above the concrete structure. Due to the size of the footprint for the two apartment buildings, pouring the slab was spaced across three Saturdays. The concrete footprint pour totaled 5,425 cubic yards of concrete covering 44,250 sq.ft.

New tenants will be able to choose from studio, one- and two-bedroom apartments and a variety of in-unit finishes including modern, casual, or higher-end finishing as well as air conditioning. There will also be a green rooftop deck with indoor and outdoor lounge spaces to relax and take in the city. The development will bring more affordable housing options to the city. Through Seattle’s Multifamily Tax Exemption program, 20 percent of the units will be priced at 65-85% of area median income, and under the Mandatory Housing Affordability rules, the project will contribute $7 million to off-site affordable housing. Center Steps is scheduled to open in Summer 2020.

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 offices are paired with a parking garage, a 4-star hotel and adjacent previously existing apartments. The parking garage includes 695,159 gross Sq. Ft. of parking space with 2,121 structured parking spaces and the ability to expand parking to an adjacent site to meet tenants’ needs. The open 12-story, $180 million, 347-room 4-star Hyatt Regency Lake Washington at Seattle’s Southport provides premium accommodations for business travelers to Southport.

This project has been a monumental achievement for the Conco Northwest Division. Under the direction of Conco’s Project Superintendent Gerrit Johnson, and Project Manager Alex Gateman, the structural duration of the project lasted over 2.5 years. Southport sets the high-water mark for the longest–and largest– contract the Conco Northwest Division has completed.

Over 2.5 years, Conco NW has:

Placed 77,400 Cu. Yds. of concrete (readymix supplied by Stoneway)
Shipped and placed 13,700,00 lbs. of rebar (installed by RPM)
Shipped and placed 1,450,000 lbs of post-tension cables (installed by RPM) – that’s more than 450 miles of cable.

With stunning views of Lake Washington and Mt. Rainier from multiple outdoor spaces, as well as a rooftop deck, tenants can enjoy the benefits and beauty of Southport with the comfort of 20% – 30% lower lease rates than in comparable alternatives in Seattle or Bellevue, a short commute to downtown Seattle and Eastside, and quick access to I-405 and I-5 Freeways.

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.

Conco Pumping was called when Vance Corporation’s usual pump supplier declined the project declaring the low slump, low cement, high fly flash 1-1/2” aggregate mix unpumpable.

The foundation for the Crafton Hills Reservoir Enlargement was not suitable and after drilling and grouting Primary, Secondary, Tertiary and in some cases Quaternary pile curtains, it was decided that the top 10’ of the foundation needed some other means of sealing. We used a Vermeer Rock Wheel to cut a 2’ wide x 10’ deep Cut-Off Wall which had to be continuously poured with around 900 yards of the low cement content mix so it would not cure too fast and develop any shrinkage cracks. The Abutments on either end rose up to 90’ on a 1:1 slope.

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.

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.
