Concrete Pumping Archives | Page 28 of 29

With the increased activity in the construction market, our Concrete Pumping division recently purchased three brand new Schwing 58X concrete pumps. The 58 meter pumps were the first of their size to be shipped to California or Washington in the last 5 years. They are the only long boom pumps in the area with engines that meet the latest emission standards.

So what exactly is a long boom pump and how does it work? A concrete pump is attached (mounted) to a truck and uses a remote controlled, articulating robotic arm known as the boom. It has the ability to place concrete quicker and more precisely than traditional methods. There are some pumps that can deliver over 200 cubic yards of concrete per hour, which one of the reasons it is economical. With the long reach of the pumps, it also eliminates much of the need to construct walkways and access points into certain areas of a project.

Here are some remarkable statistics regarding the capability of the 58 meter pump. According to the Schwing website, the pump has a vertical reach of 187’ 9”, a horizontal reach of 175’ 1”, and a below grade reach of 141’ 1”. It has a boom rotation of 370 degrees. The outrigger has a 42’ 10” overall frame length and sets up quickly utilizing the exclusive Schwing patented stable platform.

The pump specifications are as impressive. It has a concrete output of 213 cubic yards per hour and allows for a maximum aggregate size of 2.5”. The 58 meter pump even has the option of a detachable boom that can be mounted hundreds of feet from the pump.

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

Do you need to set up a pump in a lane closure and feel your only option is a trailer pump?

Next time order our 17M Special. The “17 Special” needs only an 11’-8” wide footprint with the outriggers fully extended, making it the perfect piece of equipment when pouring from a lane closure or other tight access spot.

Are you placing concrete inside a building with limited height access?

Conco has a series of specialty pumps that can be unfolded in low clearance sites such as inside a building or tunnel or underneath an overpass. The “Z” Boom and “H” Boom technology found on many of our pumps requires less clearance than older “roll and fold” models. Depending on the application, our pumps have been deployed in areas with vertical clearance as low as 13 feet!

Do you need that extra long reach?

Conco operates pumps with boom up to 58 meters (175 feet). We have also routinely pumped concrete long distances (over 3000 feet) under challenging conditions. When you have a difficult material placement, consult with your Conco Sales Professional to help you come up with a cost-effective, safe solution.
