Excavation responsibility to adjoining owner. The
person making or causing an excavation to be made shall, before starting
the work, give at least one week's notice, in writing, to the owner
of each neighboring building or structure, the safety of which may
be affected. Having received consent to enter a building, structure
or premises, he shall make the necessary provisions to protect it
structurally and to ensure it against damage by the elements which
may ensue from such excavation. If license to enter is not afforded,
then the adjoining owner shall have the entire responsibility of providing
both temporary and permanent support of his premises at his own expense,
and for that purpose, he shall be afforded the license, when necessary,
to enter the property where the excavation is to be made.
