I am looking for a civil/structural engineer (PE) to provide me with structural drawings and sketches showing layout and measurements for a simple 6-sided (hexagonal) earthbag structure with one door and two windows. The focus of this prototype is the development of a novel catenary foam dome roof system (see attached “Catenary Foam Dome - A Primer”).
Critical questions are: How would the catenary foam dome structure be attached to the concrete bond beam on top of the earthbag wall? What method would be used to determine load bearing calculations including live load, dead load, and diaphragm deflection?
I am applying for a three-phase Small Business Innovation Research (SBIR) grant for developing ultra-low cost housing using the earthbag building system. The phase 1 portion of the SBIR grant will require only a simple prototype: there will be a dirt floor, no electrical, no plumbing, no HVAC. Merritt LLC currently holds a patent on an emergency shelter container kit, and we are trying to develop that product to meet the needs of farm labor housing in the US.
The civil/structural engineer who works on this project is not expected to be knowledgeable about earthbag building, however, a general knowledge of the work done by Dr. Owen Geiger and/or Precision 1 Engineering would be considered an advantage.
I have a working knowledge of Google Sketchup, but I do not have access to AutoCAD. All deliverables must be in .pdf format for the grant submission. Please provide some samples of your work.
Pending successful completion of the phase 1 SBIR grant, the much larger phase 2 portion would involve building an entire demonstration farm labor camp that meets OSHA H2-A standards for far labor housing. So there would likely be additional work for the right candidate.
I look forward to receiving your proposal.
