The client had approached to us, asking for our assistance in providing structural design services for the architectural set he had already developed of a shipping container home in California made of two containers, one 20ft size and one in 40ft size. The shipping container home should be California Building Code compliant and stamped in order to be submitted for city approval.
As for the foundation plan. the standard common foundation plans we had designed, was piers extending above grade on the corners and middle of the length of the container, welded to a base plate, shown in the picture below.
But in this case, the architect had designed the foundation to be inset using strip footings, and the builders had recommended two options, shown below. He insisted to have the W beam to stick out past the concrete columns by 1”.
The client asked S3DA Design for advice and recommendation on what option for foundation plan would be the best in terms of cost, strength, and code compliance. Both were feasible and functional but our Engineering team recommended using Option 1 in order to meet client’s requirements.
Our Engineering team required to get the soil report and project address, and performed the following tasks for structural design services:
– Drawings: General Notes, Foundation Plan, Foundation section & Details
– Calculations: Foundation and anchor bolt design of Container, Beam design and connection design, Seismic/Wind Design Loads, and preparing detail PE stamped calculations for permit submittal
– Final construction drawings of the shipping Container Home
The full package was bind and submitted to for permit submittal and is currently under review.
