[2] Id.—Subsequent Performance of Work.—Evidence that the employees of such plaintiffs were working on the premises at the time ' of the death of the sublessee, and that all the changes contemplated had not then been made, but were completed at a later date, is not, under the circumstances, necessarily inconsistent with the finding that the contracts of the plaintiffs were completed on the date of such death.

[3] Id.—Unsupported Finding.—A finding that certain work was completed on a given date is unsupported by the evidence where the only evidence offered is the testimony of one of the claimants that the work was finished on a date twenty-five days earlier.

[5] Id.—Alterations by Lessee — Knowledge by Owners — Nonliability Notice.—Knowledge by the owners of given premises that certain alterations and repairs are to be made by their lessee is sufficient to require such owners to file the notice prescribed by section 1192 of the Code of Civil Procedure as a condition of relieving their property from liability for the cost of the work performed at the request of the lessee, though such owners have no knowledge as to the scope of said work.
