With over 15 years of international experience serving clients across the USA, UK, Australia, and the Middle East, I bridge the gap between technical theory and job-site reality. I have successfully delivered 100+ projects in AutoCAD, consistently meeting the most rigorous local and international building codes. How I Can Help You: Residential & Multi-Story Housing Specialist I design complete water supply and waste networks for Single-Family Homes, Double-Story Residences, Accessory Dwelling Units (ADUs), and Tiny Houses. My designs prioritize efficient pipe routing and hot water recirculation loops for instant pressure. Commercial Kitchens, Cafe & Restaurants I provide specialized plumbing solutions for the food service industry, including precise Grease Interceptor (Grease Trap) sizing and commercial-grade kitchen drainage that meets strict health department and municipal standards. Schools & Institutional Facilities I develop large-scale plumbing systems for educational buildings, ensuring code-compliant layouts for high-traffic restrooms, science labs, and drinking water stations. Technical Calculations & MEP Coordination I provide precise pipe sizing based on Fixture Unit (WSFU/DFU) loads and detailed Riser Diagrams. My coordination-first approach ensures that plumbing layouts are 100% clash-free with HVAC and Electrical systems before you break ground. Code & Standards Expertise My designs are strictly aligned with the following regulatory bodies: USA: IPC (International Plumbing Code) & UPC (Uniform Plumbing Code). UK & Australia: CIBSE Guidelines, BS EN Standards, and AS/NZS 3500. KSA: Saudi Building Code (SBC). UAE (Authority Approvals): Expert in preparing "ready-to-approve" drawings for DEWA, SEWA, and ADDC. Let’s bring professional-grade precision to your next project. Send me a message today to discuss your requirements! Best, Engr. Adnan Khan Plumbing Design Engineer | AutoCAD Expert

Adnan understood right away what I needed and was super responsive. I had some doubts and he guided me through it. In addition, the delivery was much faster than what was expected. I definitely recommend him and will work again with him in the future.
