Although San Jose, CA. is a largest city in the Bay Area, the Mineta San José International Airport is the smallest of the three airports in the area. Both San Francisco and Oakland airports serve a far greater number of travelers than San Jose’s.

The tremendous growth in the area fueled by the development of Silicon Valley had meant the airport was long overdue for an expansion and renovation of the facilities. The project was done in a series of stages over a period of almost ten years and is now finally complete. Conco had the opportunity to provide concrete services on one of the largest phases of the project. Our work was to help in the construction of the new Terminal B. The complete scope of work for the airport included upgrades and modernization to Terminal A and improvements on parking and roads as well as the new car rental facility, ConRAC.

Terminal B officially opened for business on June, 2010 and the airport is now considered to be one of the most technologically advanced airports in the country. The terminal received LEED Silver certification for the environmentally sustainable design and construction. According to the airport’s website, the design optimizes an “energy performance exceeding California Title 24 standards by 16%.”

Passengers comfortably await departures with amenities such as free WiFi, an abundance of power outlets for charging electronic devices, and quality restaurants and shops. A highly efficient baggage screening process utilizes a state-of-the-art automated system that is capable of scanning up to 1,800 bags an hour. The terminal now has a total of 12 gates and a large, well-designed security checkpoint.

Conco is a leading supplier of concrete services for the Western United States. As one of the leading commercial concrete contractors in the San Jose area, we have been involved with large-scale projects in the area including the Mineta Airport. Our concrete services include commercial, educational, parking and other construction development as well as public works projects and highways.

After breaking ground in April 2012, San Francisco will have a new football stadium for the 49ers that will open in time for the 2014 NFL season. The Levi Stadium is being built in Santa Clara, CA, which is located 38 miles from San Francisco. It will feature wide-open plazas, commercial space, a 49ers team store, and a 49ers Hall of Fame. The design of the stadium is intended to serve a range of entertainment and sporting events beyond football.

Here are some interesting statistics comparing the old football stadium to the new one. Candlestick Park was built in 1960 for a cost of $32 million. The new Levi 49ers Stadium will open in 2014 and will cost $1.2 billion. While the total seating capacity at the new stadium (68,500 Levi – Candlestick Park 69,900) will be lower, Levi Park will have 9,000 premium club seats and 165 luxury suites.

The new stadium is nearly a 100,000 sq. ft. larger and will feature a scoreboard that is almost 13 times bigger than the one at Candlestick. Parking should be easier with an addition of more than 3,000 spaces. Freeway access entry/exit points at the new stadium increase from 4 to 11 and should help fans coming into and out of the game.

Even the interior mode of transportation is improved by increasing elevators to 17 from the 3 in the old park and providing 24 more escalators for a total of 30. Additionally, there will be an increase in restroom fixtures from 885 to 1135 in the Levi Stadium.

The extensive concrete work done was by Conco. Upon completion, it will total approximately 60,000 cubic yards of concrete.

Coming Out of the Ground in Seattle’s Theatre District

The Holland Partner Group has come out of the ground with a new 40-story apartment building adjacent to the historic Paramount Theatre. This project, with its close proximity to Rapid Ride Transit and Seattle’s retail core, positions itself in the middle of the vibrant downtown. Upon completion this project will consist of 325 apartments, 276 parking stalls, and a restaurant and retail at the ground floor to cater to the theatre clientele.

As part of the Holland Team, Conco is performing all of the cast-in-place concrete, rebar, formwork, shotcrete and concrete pumping for this signature property. The small footprint with minimal lay-down area and five-day form cycle present challenges that require constant communication and coordination with all trades on site. Conco will be utilizing a perimeter protection system and perimeter netting system to ensure the aggressive schedule is met without jeopardizing the workplace. As of August 1, Conco is on schedule having recently completed the 12th floor. Conco will top out the project January 22, 2014.

815 Pine is designed and constructed to achieve LEED Silver status. The project is scheduled to be completed in April, 2015.

Spotlight

New challenges arise for the concrete contractor due to the growing demand for in-fill projects such as Conco’s current Essex-Elkhorn Court Apartment Homes in San Mateo, CA. The City of San Mateo is part of the Bay Area plan drafted by the Association of Bay Area Governments and the Metropolitan Commission designed to find solutions to meet the growing housing needs of the Bay Area. An integral part of their plan is to locate housing near transportation corridors and jobs. The result of doing this would generate a reduction in greenhouse gas emissions due to a less automobile traffic.

Therefore, more projects being constructed are located next to existing commercial buildings and residential complexes. These in-fill projects pose challenges such as noise, site access, and impact on the surrounding neighborhood.

The Essex-Elkhorn Court Apartment Homes will consist of 197 apartment units and have 125,978 square feet of office space with below grade parking for all. The project is being constructed by Barry Swenson Builder.

The Essex-Elkhorn project is sandwiched adjacent to a hospital, day care center and residential housing. Because of this, special attention had to be taken to lessen the impact of performing the concrete work on the surrounding neighbors including scheduling large concrete pours on weekends during designated hours only and reducing the traffic around the site by limiting mixer truck traffic by pumping concrete from one pump to another. The attached clip shows a time lapsed video for accomplishing one of four mat pours scheduled for the project.

Type of Construction:

3” Thick Mud Slab w/ 2” Thick Protection Slab over waterproofing
30” Thick Below Grade Mat Foundation Slab
Two Levels of Below Grade Parking: 8” thick Post Tensioned slabs
Podium Level at Grade: 11” thick Post Tensioned slab
Exterior Basement Walls: Shotcrete applied against shoring walls.
Interior Walls: Shotcrete with Backform
Cast-in-place Columns
Total CY (including mud slabs & shotcrete): 15,500cy

Seattle Mat Pour at The Martin

Conco’s regional office in Washington completed a 2,880 cubic yard mat pour on April 7th at The Martin–a 24-story luxury apartment tower located in Seattle’s Belltown neighborhood–for general contractor Exxel Pacific.

Located downtown adjacent to Seattle’s Monorail, access and time constraints were a concern. Three pumps–36 meter, 47 meter & 58meter–were used to complete the mat pour, together pumping 450 cubic yards per hour at peak times. Cadman, Inc. delivered the ready-mix with trucks arriving approximately every 80 seconds to fill the mat which measures 7′-6″ at the deepest point.

With 2,880 cubic yards and 275 tons of rebar, The Martin stands as affirmation of Conco’s abilities and reputation.
