I didn’t think it was the fault of the design; rather, the installation. I wonder whether the design engineers provided instructions on installation I would think they did. So there may be fault there.

Maybe it was pictorial diagrams, like IKEA furniture.
In most cases the design engineer or architect do not give the constructor instructions on how to build the project. The contractor is expected to hire his own team to manage the construction process. They schedule each step and how it should go together. Then the engineer might have been asked to review their work plan.
