I hired Precedence in November 2024 to help me develop architectural and MEP plans for my first home renovation in DC, and they made the process feel easy. Wisam was responsive, took the time to really listen, and helped navigate feedback from the DOB without a hitch. I recommend them if you're looking for thoughtful, hands-on support from start to finish.
Precedence Engineering Consulting(PEC)'s reply
Hi Malcolm, Thank you so much for the kind words. It was truly a pleasure helping you with your first renovation in DC. I'm glad we could make the process easier for you and that the DOB feedback went smoothly. Always here if you need anything for future projects. Best regards, Wisam
