Attached you will find a Foundation Engineering assignment in which a retaining wall must be designed with stability considerations in mind. A well-detailed and dimensioned drawing of the wall cross-section & placement of any drainage features is required. In addition, ALL calculations should be clearly provided. The design should be the most economical (i.e., smallest) retaining wall cross section that satisfies ALL of the stability requirements. Also, comments should be made regarding drainage provisions for each wall and how they would impact the design.
I have 8+ years of experience in structural analysis and design using international standards and hold masters degree in structural engineering. Have also worked on several similar designs earlier.
