ACE ONE Engineering
ACE ONE Engineering
I'm a fully insured Professional Engineer (PE) in Pennsylvania, Ohio, Maryland, West Virginia, and Idaho with over 13 years of AutoCad and engineering experience. I have a knack for turning client's visions from ideas in their mind to construction drawings, ready for fabrication. I often work with clients who required stamped engineering drawings and assistance navigating the permitting process for their project. My specialty is residential and light commercial construction engineering which includes anything from new house design to additions on existing homes; complete floor plans with mechanical, electrical, and plumbing details; beam and column sizing; and even deck, patio, and retaining wall design. If this doesn't fit your project, there is a very good chance I could still be a great fit for you, as I always enjoy adding new and unique projects to my portfolio. If you're looking for an engineer for your next exciting project, please reach out to me at 724.799.1420. I'll be happy to help get the ball rolling.

"Tim is the consummate professional. He's very thorough in his inspection, and he writes clear reports with excellent pictures. His report on the termite damage was much better than that done by our original inspector. He explained everything he found so I felt like I had a good picture of what needed to be done. When he returned, my contractor was so impressed with him that he took his contact information to refer him to future customers who needed engineering reports."
