Mortenson was selected as EPC contractor to build five, utility-scale solar projects totaling 400 MWdc over a three-year period in the San Antonio, Texas area for a first-time customer. The San Antonio-based project owner and developer was responsible for delivering the solar-generated energy to CPS Energy. In addition to delivering energy, the project teams created new energy-related jobs within the San Antonio area.
The team designed the 48.4 MWdc solar systems for Alamo 4 and construction activities began December 2013. Virtual Design and Construction (VDC) was used to evaluate the site’s existing slopes to optimize grading and maximize the arrays built. The civil project teams used machine-controlled grading models developed by the VDC team to GPS control earthwork moving equipment and minimize survey work. Over 500 craft workers were employed to self-perform the work, including the installation of over 160,000 solar modules on dual-axis trackers.
