Installation Guide Summary

Note: A comprehensive and detailed installation and assembly guide is included with each purchase to ensure precise and correct setup.

1. Container Alignment

Position your shipping containers to align with the predetermined width dimensions of the shelter. This ensures that the entire dome structure will fit securely and maintain stability.

2. Base Rail Assembly

Assemble the steel base rails by joining them together as per instructions. Once assembled, install these rails along the top edge of each container. This forms the foundational support for the arches.

3. Arch Construction

Lay out the arch sections on a flat surface. Carefully attach these sections together to form the complete arch structure. This step requires attention to detail to ensure each section is correctly aligned and securely fastened together.

4. Arch Installation

Proceed to lift each assembled arch one at a time. This step will require lifting equipment depending on the size and weight of the arches. Positioning each arch onto the previously installed base plates on top of the shipping containers, and secure them down.

5. Cover Installation

Start by gently unpacking the shelter cover onto a flat surface. Lift the cover onto one container, then methodically pull one side of the cover up and over the arch to the other container.
