At Canada Post, the door-to-door delivery program was transitioning to a community mailbox (CMB) based delivery mode. New bases were needed when concrete pads weren't appropriate (e.g. if it was in a parking lot, or a temporary installation).
Initial forms used more rounded, smooth forms. But when it was realized I couldn't alter the form of the existing CMB, I opted for a more rectilinear shape to better suit the overall aesthetics. It was further developed to meet the design requirements of the installation engineers.
I sourced a pre-cast concrete supplier to create prototypes for testing.
A prototype was wind tunnel tested at the NRC to determine stability. It has to pass a Category 1 hurricane wind force (120km/h). (Click this image to view a video of the testing)
Installation procedures were tested on site.
After a wide range of installation tests and approvals, the design was finalized for public use.
