Conco’s work on the award-winning Salesforce tower in San Francisco

The Conco Companies has established itself as a premier commercial concrete contractor in San Francisco through its work on several prominent large-scale construction projects over the years, such as the repair of the Bay Bridge, the new 49er’s stadium, and the UCSF Neurosciences Lab and Research Center. For this reason, Conco was contracted to provide concrete services for the construction of the Salesforce Tower in the South of Market district of downtown San Francisco. For their part, Conco placed 110,000 cubic yards of concrete with concrete pumping to create the massive skyscraper’s core interior walls and foundation. This project was the largest mat pour in San Francisco’s history, requiring 18 hours to complete. The monumental efforts of the building’s architects, engineers, construction teams, and Conco yielded stellar results, as the Salesforce Tower has gone on to receive multiple awards and recognition across the industry.

What is a Concrete Pump?

A concrete pump is a machine which transfers mixed concrete (i.e. in liquid form) through pipes via a pumping action. Previously, when concrete was needed on a jobsite the materials were mixed onsite and transported via wheelbarrow or bucket. As you can imagine, this method became very tiresome and expensive for large-scale projects such as high-rises. Thankfully, in 1927 Max Giese and Fritz Hull designed a solution which pumps concrete through pipes from a single concrete source (this design was improved upon in 1957 with dual hydraulic cylinders and remains the standard design today).

Types of Concrete Pumps

There are two main types of concrete pumps: boom pumps and transport pumps.  A boom pump is a concrete pump with a remote-controlled “boom” arm attached and a line pump is a concrete pump that is attached to a vehicle. The principle difference between these two types of concrete pumps comes down to the additional appendage equipment attached to the pump and volume. Boom pumps can pump at higher volumes than transport pumps and are typically used for larger projects. Other concrete pump variations include:

• Mobile concrete pump (truck mounted mobile)
• Stationary pump
• Truck mounted static pump
• Truck mixer concrete pump

Outside of the increased convenience of having concrete pumped to the worksite, concrete pumps offer a number of additional benefits over manual methods. First and foremost, concrete pumps allow for a steady and precise flow of material creating a smooth finish. These tools also help to save time, reduce worker fatigue, and improve the quality of the concrete.

Watch Our Crews in Action on a 4,620 Cubic Yard Mat Pour

   

 

If you want an opportunity to see our highly-efficient Conco crews at their best, take a look at our time-lapse video of the 4,620 cubic yard mat pour for the 970 Denny Way project.  The mixed-use redevelopment project in Seattle, Washington is being developed by the Holland Partner Group, with Holland Construction acting as the general contractor.      

The 970 Denny Way mat pour took place on July 23^rd and was done over approximately 15 hours.  Our crew started at 2:00 am and finished around 5:00 pm.  The job took 4,620 cubic yards of concrete to form the 15,300 square foot mat foundation for the new 40-story apartment/retail building. In addition to the concrete, the foundation also used 1.3 million pounds of rebar.  All of the ready mixed concrete was supplied by CalPortland.  Our video adeptly illustrates the kind of teamwork required to get such a large job done in a relatively short amount of time.  

Now that the mat pour is complete, construction on the South Lake Union neighborhood building has begun in earnest.  Once it is finished, the building will feature 468 apartment units in various configurations, 15,580 square feet of retail space, and four levels of sub-grade parking.  The core of the building will be constructed using 386 steel fiber-reinforced concrete coupling beams. 

Our website and YouTube also have a selection of other mat pours that we have completed over the last several years.  One of our time-lapse videos is for an impressive 12,000 cubic yard mat pour for a new skyscraper under construction in the heart of the financial district of San Francisco. This massive pour was completed over the course of 16 hours.  Along with the help of 7 concrete boom pumps, the project went off without an accident or any problems despite the challenging logistics and setting.
