I’m ready to build a 50-foot long retaining wall that will start at roughly 40 inches in height and taper smoothly to ground level. The wall will back a future patio, so it must safely resist surcharge loads while still presenting the natural look of stacked fieldstone. We are working with natural boulders only—no concrete blocks or gabions—and the native soil on site is a heavy clay. Here’s what I need from you: • Signed, build-ready engineering drawings (PDF and CAD) showing plan view, elevations, typical cross-sections and any required step-downs along the length of the wall. • Structural calculations verifying stability against sliding, overturning and bearing failure, taking the clay soil properties into account. • Clear specifications for footing preparation, drainage blanket, filter fabric, geogrid (if you feel it’s needed) and backfill compaction. • Notes that a local contractor can follow for boulder selection, placement tolerances and final grading behind the wall. • A brief summary sheet I can submit to the city if permitting is required. If you hold a professional engineering licence that can be stamped in my state, please mention it; otherwise, un-stamped plans are still acceptable as long as they are complete and technically sound. I’ll share site photos, a rough survey and any additional measurements as soon as we begin. I’m looking to move quickly, so let me know your timeframe for the first draft and how many revisions you include.

Hi, I reviewed your scope, and this is a structural problem, not just a layout. A boulder retaining wall on clay with surcharge needs proper stability checks or it will fail over time. I can prepare build-ready drawings with plan, elevations, sections, and step-down logic, along with full calculations for sliding, overturning, and bearing based on your soil conditions. Drainage, backfill, and geogrid (if required) will be specified clearly so the wall performs, not just looks right. I’ll also include practical notes for boulder selection, placement, and grading so a contractor can execute without guesswork. You’ll get a clean summary sheet for permitting and organized CAD/PDF deliverables. Once we connect, I can walk you through similar structural work and approach. Quick question, do you have a soil report or should I assume typical clay parameters? Best regards, Muskan

Your 50-foot boulder wall project is a structural engineering task where balancing aesthetics with lateral stability is vital, especially as you reach the 40-inch height threshold. I have designed numerous gravity-based boulder systems and tiered slope stabilizations, ensuring the mass of the rock effectively counteracts soil pressure. My focus is on providing a permit-ready set of engineered plans that prioritize long-term durability while maintaining a natural look. I have a deep understanding of structural codes regarding dry-stack boulder construction and how to optimize stone sizing for maximum site safety and project cost-efficiency. To ensure stability, I will calculate active earth pressure based on your specific topography and soil friction angles. Using AutoCAD for structural drafting, I’ll determine the necessary boulder graduation and inward batter to keep the center of gravity securely within the wall’s footprint. The design will include a comprehensive drainage plan—featuring non-woven geotextiles and a clean-stone drainage chimney—to eliminate hydrostatic pressure, which is the primary cause of wall rotation. I will also specify the exact embedment depth and sub-base compaction requirements to prevent frost heave or toe-out displacement over years of service. Do you have a soil report, or should we proceed based on standard regional soil assumptions? Also, is there a significant slope or a driveway above the wall that would add a surcharge load to the design? I’m available to discuss these technical details or specific permit requirements further. Feel free to reach out for a quick chat or a brief call to align on the technical scope whenever you are ready to move forward.

This isn’t just a retaining wall, it’s a structural system that needs to perform under real load, especially with clay soil, so I approach it with engineering precision, not guesswork. I’ll deliver complete, build ready drawings with plan, sections, and step downs, along with clear calculations covering sliding, overturning, and bearing stability. Drainage, backfill, and base preparation will be defined properly to prevent long term failure, not just pass inspection. You’ll also get practical construction notes so contractors can execute boulder placement correctly without ambiguity. I can move fast on the first draft and provide structured revisions to ensure everything is solid before submission. Best regards Atik Murtaza
