Structural Design for Concrete Retaining Walls

I need an expert in structural engineering to undertake the design of my project's foundation and retaining walls. This design is crucial as these structures have several pivotal roles, including:

- Acts as supports for the building
- Mitigates soil erosion
- Maximizes usable space

The retaining walls' planned height and length are 5-10 feet, meaning your expertise must accommodate these dimensions. Concrete will be the principal material for these structures, so familiarity and experience working with concrete in structural engineering contexts are essentials.

Ideal Skills:
- Proficiency in structural engineering, specifically for buildings
- Proven experience with designs for preventing soil erosion
- Experience in optimizing space in design
- Knowledgeable in the use of concrete for foundation and retaining walls.
