The project ran without a facade consultant, so we ran the structural calculation ourselves. It found material sitting where the load did not call for it, and not enough of it where the wind load at that height did. We presented the results directly to the architects and proposed our own systems in their place. The proposal was adopted, and we worked through the specification changes with them until the design met the budget.
