Please only respond if you are an engineer with experience in designing large steel structures.
Requirements: Steel frame required measuring 40' L x 8'6" H x 8' W. Frame to hold two boxes measuring 20' x 7'10" H x 7'3" W. Shipping platform frame needed must weight no more than 1,500 pounds. It must allow lifting of the the two 20' boxes as one 40' containment unit at international ports, and must be able to be lifted using port loading equipment.

Candidates with experience and a positive past reviews on Freelancer, will be provided additional information upon signing NDA or similar protection through Freelancer. The four corners must be able to hold 46 tons of overhead weight each if required. We are open to material choices that can provide the strength required, while coming in at our below 1500 pounds for the entire shipping platform.
Again, PLEASE DO NOT respond to this opportunity if you are a graphic designer, illustrator, or creative person only. This project is strictly for educated structural engineers. All others will be deleted without review. We ask those candidates who are degreed structural engineers to state that clearly in your introduction to make it easier to sort the responses.
