Andrew Alvarran

Project Coordinator

Andrew Alvarran joined Terra-Petra’s team as an intern in 2012. In the year prior, he gained familiarity with methane barriers working as an installer for the Barber-Webb Company. In this capacity he became familiar with installation techniques, applications, and testing methods for HDPE and Paraseal membranes at different construction projects and landfills across California.

As Andrew developed an understanding of Terra-Petra’s operations and design processes, his role shifted from intern to Project Coordinator. Having earned his Civil Engineering Degree in 2016, Andrew can now apply his environmental background and technical knowledge to real-world projects in the environmental engineering field working for Terra-Petra.

As a Terra-Petra Project Coordinator, Andrew assists with a variety of tasks including coordination with architects, responses to RFI’s, plan check submittals, and quality assurance/control (QA/QC). Under the direction of Terra-Petra’s Professional Engineer, Andrew performs blower calculations for active venting systems and has been successful in getting multiple modifications approved by the Los Angeles Department of Building and Safety (LADBS). He also occasionally performs soil gas investigations at suspect properties with his Deputy Methane Barrier Inspection (DMBI) license. Andrew has also earned his Engineer-In-Training (EIT) Certification and with this hopes to one day fill the role of Terra-Petra’s Professional Engineer.
