Question

A man was jogging with his puppy along a busy local street, there was house construction happening near by and the jogger stepped on a fairly large piece of concrete (4 by 3 in) which blended into the sidewalk well that was without a doubt from the construction site. He hurt his ankle (severe sprain or possibly a fracture) and is unable to work on his farm, is hard for him to walk to class and take care of his dog now. He is on crutches for a week and in a splint for a month.
What charges if any would he have against the construction company
