The Conco Companies is providing concrete services for The Mark, a new 48-story high-rise tower in Seattle that will consist of 528,000 sq. ft. of Class A+ office space as well as a SLS hotel and spa. Conveniently located in the city’s central business district, the tower will incorporate a wide range of “green” building features. Scheduled for completion in April, 2017, the tower will bring to the area first-class office space that is highly divisible and offers spectacular views. The unique geometric facade provides exterior seismic bracing for structural safety as well as offering column-free floor plates. The Mark is seeking LEED Gold certification.

The 5,000 cubic yard mat foundation pour was completed in June, 2015 and required approximately 500 truckloads of concrete over the course of the day. The project also includes a sub-level parking structure comprised of shotcrete perimeter walls and a concrete elevator core. As of May 2016, Levels 5-11 decks have been poured and the core poured to Level 35. When the elevator core reaches Level 35, the remainder of the building steel will be erected in one continuous phase. The Mark has 9 floors below grade and 44 floors plus the roof above grade.

The Conco Companies are providing the structural concrete services for Riverside County’s East County Detention Center (ECDC) located in Indio, California. The 516,000 sq. ft. project is a replacement and expansion to the existing Indio Jail Facility and is being constructed in two phases. The project consists of a three-story support building with a connecting tunnel to a four-story structure containing two housing units and mezzanine levels.

Conco’s responsibilities include supplying and performing services totaling 55,000 cubic yards of concrete. The four-level housing units are stacked in two separate “pods” and will be constructed of cast-in-place concrete as will the support building. We are also utilizing our pumps to pour piles 60’ below ground-level for Becho, another trade partner. Final completion of the project is expected in December, 2017.

One of the project’s unique challenges is that the temperatures in Indio average 89°F and summer highs can reach 120°F. Crew safety becomes even more critical in this environment. We will have a full-time safety manager on site and the 100+ Conco employees and Conco subcontracted employees are adhering to ACI’s Hot Weather Concreting procedures.

The Conco Companies’ “one stop” shop approach is being fully utilized in the construction of a new 236,000 gross square foot office and retail building in San Jose, CA. The luxury Santana Row Lot 11 is being developed by Federal Realty and Westwood Development Partners with DevCon Construction serving as the General Contractor. Features of the Class “A”, 6-story building includes 13-foot ceilings, outdoor terraces, and an onsite café as well as a four-level underground parking garage. Santana Row Lot 11 is targeting LEED Gold certification and scheduled to be completed in 2016.

Conco’s extensive scope of responsibilities takes full advantage of our broad range of expertise. For the Santana Row project, we will provide all of the formwork, reinforcing, stud rail fabrication, post tension, shotcrete, pumping and belting services. In addition we will be employing our Direct Feed capabilities to save time and labor costs.

During the course of the project, we expect to finish 585,000 square feet of concrete as well as pump 26,000 cubic yards of concrete and 2,000 cubic yards of shotcrete. Furthermore, Conco will provide 5,000,000 lbs. of reinforcing steel and 240,000 lbs. of post-tensioning.

Reliable Trucking Company, owned and operated by The Conco Companies, will transport the equipment and materials.

The VA Mental Health and Research building currently under construction in Seattle is a prime example of the benefits The Conco Companies bring to a project with our ability to provide a full range of concrete services. Conco is providing all of the concrete pumping, formwork, place and finish and shotcrete services for the 203,000 square foot project as well as supplying the reinforcement. Our unique ability to supply both the rebar and formwork eliminates the need for coordination between different suppliers to better meet the extremely tight timeline required of the project.

The 6-story building will be comprised of a steel frame with concrete fill on metal decks at all elevated levels, buckling restrained braced frames grounded on shallow spread footings, concrete cast-in-place walls, and green roofs. Since the entire façade is made up of a customized wall system, the project presents a distinct challenge with its need for high cast in place and architectural walls.

Highlights of the building include energy-efficient systems, two landscaped indoor courtyards, a rainwater-harvesting system for irrigation, and a grass covered rooftop. The project is expected to be completed in late 2017 and achieve LEED Silver certification.
