Drawings worked on paper, but there were 2 – 3 foot changes that were made clear once the architectural model was built. The model made it apparent they needed to look at certain features. For example, the entire front entry was redesigned after the model was delivered, requiring a modification to the model. The ambulance entry was too small! Architectural scale models allow developers to make major corrections before it’s too late, greatly reducing the potential for cost overruns and redesigns.
