I had an excellent experience working with Mehdi, Principal Engineer and Director of Deltoid Consulting. From the beginning, Mehdi took the time to fully understand my project and was very thorough and detailed in explaining the process and requirements. He was meticulous in preparing the grading drawings for the minor variance application. His professionalism, expertise, and attention to detail played an important role in addressing the City’s requirements. The approved grading drawings were a significant factor in getting my minor variance approved. I highly recommend Mehdi and Deltoid Consulting for their professionalism, expertise, attention to detail, and commitment to their clients. I truly appreciate the quality of work and support provided throughout the process.

Deltoid Consulting was highly responsive and generous with its time throughout a difficult permit process. Mehdi understood the constraints facing a nonprofit project in an old church building and worked closely with us through multiple design revisions and discussions with the City. Although the process was challenging, he remained available and supportive at every stage, and we ultimately received our building permit. We appreciated the commitment, patience, and care that Deltoid Consulting demonstrated for the project.

Mehdi was great to work with on our garden suite design. He handled both the architectural and engineering drawings, and everything was clear, practical, and easy for the city to review. Compared to our other projects, the permit process was noticeably faster. He’s responsive, easy to communicate with, and understands how to get things done efficiently. Would definitely work with him again. Quantum Garden Housing

To whom it may concern, I hiired Mehdi for residential renovation projects. For those projects he prepared detailed design drawings after taking measurements physically, and obtained approval and building permits from the city of Richmond Hill in order to proceed with the construction, without me having to do anything. Indeed, I found Mehdi to be very knowledgeable and highly proficient in the jobs he undertook.and to be mindful of the time constraints. Also what's most notable in him is that he is very courteous and maintains a high standard of professionalism. As a professional engineer, he strictly abides by the code of ethics.and maintains customer satisfaction at all times. Indeed, from my highly satisfactory experience with Mehdi, I have recommended him to many of my contacts.who are looking for construction services. Kind regards Dave Devendra.
