Aguirre & Fields

Aguirre & Fields is united by a passion to serve communities where we live and work. We began as a bridge firm in ‘99 but today we’re bridging the gap between traditional engineering and servant-leadership.


How do we do this? We focus on building partnerships over building projects, first by identifying emerging communities with long-range needs and next by reimagining solutions for these communities across four main engineering disciplines: Strategic Planning, Transportation Engineering, Construction Engineering Inspection, and Civil Engineering.


Founders Oscar Aguirre and Richard Fields laid the foundation for a unique company culture focused on strong character, service and bettering communities. Our projects are designed with precision and built strong, considering a community’s needs 10, 20, or even 50 years from now.


With over 20 years' experience, we’re proud to be engineering innovators entrusted by communities across Texas and Oklahoma to create and implement solutions that make life better for everyday citizens.
