Professional Engineering Services (PES)!


Welcome to PES

PES, LLC (former AEC, Inc.) was established by Mr. Ali Shasti, P.E., MSCE, in Plant City and Zephyrhills, Florida, in early 1999. The company has provided complete high-quality engineering and consulting services to clients from all walks of life. AEC, Inc. has provided these services at a fair and reasonable cost and efficiently to ensure high returns and profitability for their clients. It was because of this dedication they have enjoyed continuous and consistent growth; clients return to AEC for additional services repeatedly.

Ali also authored and published the SITE DESIGN & ENGINEERING, a Site Development, Construction Plans Preparation and Permitting Guide in 2022. He is currently focusing on the second edition of his book, SITE DESIGN & ENGINEERING. Your feedback regarding the first edition will be greatly appreciated. SITE DESIGN & ENGINEERING can benefit anyone working on any residential or commercial site development project. 

Ali is also available to provide engineering, consulting, and permitting services as a consultant engineer for more complicated and challenging projects or where the clients feel the project is at an impasse.
