Several years ago Conco provided concrete services for United Spiral Pipe to help build a new state-of-the-art spiral welded pipe manufacturing plant in Pittsburg, Calif.   United Spiral Pipe LLC (USP) is a joint venture of United States Steel Corporation and two South Korean firms, the steelmaker Posco and SeAH, a spiral steel pipe manufacturer.

Concrete Pumping - United Spiral Pipe

The USP facility broke ground in February, 2008 and started commercial production in January, 2010.  It is estimated that over 320,000 hours of building and construction trade labor was used in the project.  The plant is one of the most advanced and efficient spiral pipe mills in North America to-date with an overall cost of $130 million.  It was constructed to LEED standards and exceeds California’s Title 24 lighting requirements.  The architect and engineer on the project was the Continental Design And Management Group.

USP is a great addition to the city of Pittsburg as well as the whole Bay Area community.  When the plant first opened, it provided 120 new, full-time manufacturing jobs.  That was a good step in the right direction for an area that they had been losing manufacturing jobs.

The size of the new facility is enormous.  The rectangular shaped building is 35 ft. tall, more than six city blocks long, and approximately a block and a half wide.  According to the USP website the “new plant will have world-class pipe making and coating facilities and be capable of producing 300,000 net tons of API specification line pipe per year in outside diameters ranging from 24 inches to 64 inches.”  The massive steel pipes are used to transport oil and natural gas for the expanding North America pipe market.

The range of construction projects that are grounded in quality foundation work, substantial reinforced walls, and strong parking structures that are a result of Conco’s concrete services is extensive.  A few years ago, the woefully under-serviced energy market in Southern California was addressed when the General Electric Company, along with managing partner, the Calpine Corporation built a new energy plant.  Conco’s services were enlisted to help in the construction of the large plant.

Inland Empire Energy Center Construction

The 800MW, natural gas-fired Inland Empire Energy Center is capable of meeting the energy demands of close to 600,000 households and is located in Romoland, CA. in Riverside County.  The plant came online in 2008 and sits on 46 acres.   The architect and engineer for the project was Parsons E&C and the total cost of the project was $500 million.

The Inland Empire Energy Center is a state-of-the-art facility and was site for the “launch of GE’s most advanced gas turbine technology, the H System.”  This innovative technology “enables the H System to provide superior fuel economy and environmental performance.”*   According to GE, the result is that the efficient H system uses less fuel and produces fewer emissions than other large gas turbine systems.

Calpine Power was the construction manager, and when the plant came online, Calpine Energy became responsible for the marketing of the energy.  At some point, under a pre-arranged agreement, the Calpine Corporation will buy the plant from GE.   Conco was pleased to be a part of a project that serves the communities of Southern California and provided a means to reducing air pollution.

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.

Long Boom Concrete Pumps   1650 Wewatta 0002

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.

Conco is one of the leading commercial concrete contractors in Sacramento and has been delivering first-rate services in the area since 1959.  We are experts at creating cost-effective solutions that take advantage of the most up-to-date techniques.
