Buying More Time for CPS Headquarters

CPS Energy has been in the news quite a bit lately concerning their new headquarters in the old AT&T Building downtown. Did you know that G.W. Mitchell (GWM) helped CPS grow and expand in their current building, allowing them more time in their current headquarters?

In November of 1984, GWM began work on the challenging task – building an additional three stories to the existing seven story CPS building in a very tight space at 145 Navarro Street. Being located in the heart of downtown San Antonio, there was no laydown area as the job was constrained on all four sides by Villita Street, Navarro Street, the River Walk and the Tower Life parking garage. The job required the construction and design team, including 3D/I Architecture, to work very closely and creatively with the owner, city and subcontractors to complete the project. In total, the addition was a 61,000 square feet expansion of an operating office building.

GW Mitchell bid the project but was actually selected by CPS to do the work because of their logistics plan, not because of the bid. A tower crane had to be erected in one lane of Villita Street and the tower crane base had to avoid hitting live sewer and water mains. All deliveries were scheduled on a “just on time” basis as there was no room to lay down the structural steel, brick, etc. The brick and cast stone façade were selected and manufactured to closely match the existing brick and cast stone materials and were installed using San Antonio subcontractors.

The original CPS Headquarters building was built right here in the heart of San Antonio in 1942, and since then CPS Energy has serviced over 800,000 electricity customers and over 300,000 natural gas customers in Bexar County and portions of its seven surrounding counties.

As CPS is a large contributor to the San Antonio area, we at GWM are glad that we could give back over 30 years ago and contribute three additional stories to its headquarters. Despite the challenges at hand, and weather delays due to the snow storm in January of 1985, GWM finished the project exactly one year after it began just in time for the holidays.

CPS just received a set guaranteed maximum price of $150 million to build their new headquarters at what is now the AT&T building off McCullough and Avenue B. With a rich history on Navarro Street, the utility company is looking ahead to building a bright future at their new home.
