Conco Pumps 5,700 cubic yards for Downtown San Francisco Mat Pour

On March 3 & 4, 2012, Conco successfully pumped 5,700 yards of concrete for the 1401 Market Street Project in Downtown San Francisco. Located on the edge of the Civic Center and Financial District, this project comprises a 35-story tower along with buildings of 9, 12, and 19 stories. The project will contain 720 residential units along with ground level retail and two levels of above ground parking.

The concrete was supplied for the project’s first mat foundation pour. Jobsite mandates required the concrete pour to begin after sunset on Saturday evening and finish Sunday morning. Gary Brandt, Vice President of Marketing with Conco, worked with the owner, the general contractor, the concrete contractor and the ready-mix supplier to develop a game plan and secure the necessary permits needed to pull off this logistical challenge.

Conco provided three 58-meter Schwing pumps, one 52 meter Schwing, one 47 meter Putzmeister and a 36 meter Schwing. The limited jobsite access required a pump positioned down in the hole to be supplied by one of the 58 meter pumps. Throughout the pour, concrete was being pumped and placed at the rate of 600 yards per hour allowing the pour to be finished in 10 hours. The pour was completed without any lost loads, injuries or complaints from the general public making it a success for all parties involved.
