About

TJCAA’s head designers, Terence (Terry) Cavanagh and Paul Giorsetto, were principals and design leaders for an international environmental engineering design firm in California’s Bay Area. Mr. Cavanagh and Mr. Giorsetto together provide over 50 years of experience in delivering creative problem solving for public and commercial/industrial clients. The TJCAA Structural Group provides expertise in the design of water and wastewater treatment plants and seismic evaluation of existing structures, as well as in the design of ozone treatment and chemical containment facilities. Our Instrumentation, Control, and Electrical Group has developed designs for low and medium voltage distribution systems and control systems for complex water treatment facilities both domestically and internationally.

In 2012, Mike Erwin joined the TJCAA group, bringing to bear his 30-plus years of experience as a designer and system integrator working on control systems in the water and wastewater industry. Mike has been the point person for expanding TJCAA services to include Control System Programming to our suite of services. Our CSP group, with its growing staff of system programmers, brings a combination of PLC and SCADA programming skills coupled with design and field experience to implement practical and effective CSP solutions.

TJCAA and its personnel are responsive and flexible team members. We have demonstrated our ability to provide quality service, both as a lead firm and by integrating effectively with existing design teams. We work toward the best solutions for our clients. TJCAA operates from our fully equipped design offices and is also comfortable operating remotely or on site as part of an existing design team.
