Structural design

I am looking for a skilled structural engineer to design a channel in an existing concrete sub-floor (existing design as constructed attached) for new plumbing (flows attached) in the ground floor of my house. I have specific requirements for the project that must be met, and require the design to be completed within 1 month. An individual or team experienced in designing structures that meet legal, economic, and safety requirements is ideal for this project. If you believe you have the expertise needed to complete this project, please reach out to discuss further details.
