Keystone Engineering is a multi-discipline engineering consulting firm with over 300 employees; our locations include Metairie, Mandeville, Baton Rouge, Lafayette, and Houston.


We offer civil/structural, mechanical, process, electrical, instrumentation and controls & automation engineering services to a largely industrial clientele. We also offer design and engineering for offshore renewables platforms and marine terminals. Our goal is to provide our clients with practical solutions and excellent design in a common sense, results-oriented manner. 


Keystone is dedicated to providing a quality work product in a schedule-conscious, safe and cost-effective way.


Our flexibility allows us to handle a broad range of project needs, from small efforts like a simple field sketch to multi-discipline project teams for large capital projects.


Each office is run by a General Manager that has a vested interest in our product and reputation. These owner-managers and engineers provide daily project oversight as well as hands-on involvement in our projects, allowing the most focused energy and effort to be spent on the quality of the end product.


Keystone Engineering Inc. is registered in several states, including Louisiana, Texas, Mississippi, Tennessee and Oklahoma. Currently we have over 69 licensed engineers on staff, and reciprocity agreements with many states. Our goal is to be a regional leader in engineering design services, and to provide a family atmosphere to our employees. By leveraging decades-old relationships and a hard-working, common sense approach to projects, Keystone is well-positioned to continue steady growth and development.
