Opinion by
*423 Mrs. Margaret Prost was injured when she slipped and fell in the terrazzo-paved entranceway to a department store in Washington, maintained and operated by Caldwell Store Incorporated. With her husband she brought a suit in trespass against the store company which brought in as additional defendants the H. Kaplan Company, general contractor, and the firm of Pastura and Popovic, subcontractors, which installed the terrazzo.
The Kaplan Company filed preliminary objections to the defendant’s complaint, contending that Caldwell’s claim against it, if any, could only be for breach of some contractual duty it might owe Caldwell and that, therefore, it could in no way be made answerable to the claim filed by the Prosts. The lower court sustained the preliminary objections and entered judgment in favor of Kaplan. Caldwell appealed.
The lower court held that according to the Pennsylvania Rules of Civil Procedure joinder is permissible “only in defense of plaintiff’s claim and does not permit joinder so that defendant may make a claim against the additional defendant.”
It is true that under Pa. R. C. P. 2252(a) the claim for liability over must relate to the cause of action declared on by the plaintiff and the original defendant may not assert a claim against an additional defendant which is entirely independent of the plaintiff’s claim. This is so even though the latter claim may have arisen out of the same factual occurrence from which the plaintiff’s cause of action arose. Thus, if the additional defendant’s liability is to the original defendant exclusively and is based solely upon a contract between them, the additional defendant’s liability does not relate to the “cause of action declared on” by the plaintiff in the original trespass complaint.
However, the decision of the court below is based on the erroneous assumption that Kaplan’s liability *424 can arise only out of the contractual relationship between Kaplan and Caldwell. The court evidently overlooked or gave but scant heed to the assertion by Caldwell that Kaplan’s liability extended to the plaintiff on the ground that Kaplan had negligently performed its work to the detriment of not only Caldwell but the world in general. Caldwell’s complaint specifically charged, inter alia, “The additional defendants poured and caused to be poured terrazzo tile which they knew or should have known would be used by the public generally and the result of their work was to create a dangerous, slippery, unsatisfactory flooring; The additional defendants created a hazard to the public generally and especially to users of the vestibule when they negligently constructed a terrazzo tile floor of such a slippery nature; The general contractors, H. Kaplan Company and the subcontractors, Pastura & Popovic, were both guilty of faulty workmanship, the use of improper materials, and of failure to warn the public generally of the hazardous condition which they had created.”
The original defendant’s complaint agreed with the plaintiffs’ complaint wherein the latter said that the fall of Mrs. Prost was “the result of the conditions aforesaid and the negligence of the defendant, its agents, servants, or employees in the following particulars: (a) in constructing the said entranceway and vestibule of a material with a waxy or slippery surface when they knew or should have realized it would be considerably trafficked and walked upon . . .”
The pleadings thus specifically charge that the Kaplan Company breached a noncontractual duty owed directly to Prost and that Kaplan’s liability is by no means dependent upon the contract between it and Caldwell.
The lower court, in support of its decision, referred to the case of
Evans v. Otis Elevator Co.,
As already indicated, the Caldwell complaint specifically charged Kaplan with negligence in producing *426 a dangerous, slippery floor because of the negligent manner in which it poured the terrazzo tile. In the Evans case, the Otis Company was charged with negligent inspection of an elevator, this negligence resulting in an accident which visited serious injuries on the passenger-plaintiff. In holding the Otis Elevator Co. liable, despite its contract with the owner of the building maintaining the elevator, Justice Jones said: “Such principle finds support in reason, justice and precedent,” citing at least ten cases.
In the case at bar the court below said that “Had the additional defendant left a hole or some obstruction in the flooring which caused the plaintiff ... to fall and be injured,” liability could attach against Kaplan. What is the difference in principle between a negligently formed hole through which a pedestrian falls to his injury and a negligently constructed floor to which a pedestrian falls to his injury? The only visible difference is the distance of the fall. The defect is always the same, namely, a defect in the flooring over which the pedestrian must walk. Whether Kaplan, because of defective craftsmanship, left a hole in the floor, or, whether because of incompetence or negligence, failed to put into the terrazzo the indispensable substance which would insure pedal sure-footedness, the result would be the same, the pedestrian would have fallen because of the instrumentality of Kaplan’s negligence.
The appellant states that “the fall occurred long-after the contract was completed and after the work was accepted by the original defendant,” and argues that “A contractor should certainly not be held responsible for conditions which arise after he is out of possession or control.” Such an argument, if accepted into law, would absolve a contractor from liability under the most flagrant circumstances of negligence. A bridge contractor, for instance, could stuff the piers with sawdust and plead nonliability if the bridge fell, *427 since Ms work wouM have been completed before tbe public began to use the bridge.
In
Bisson v. Kelly, Inc.,
The law recognizes an obligation to society and humanity which cannot be whittled away by the lean knife of inapplicable technicality. The person who designedly or unwittingly constructs a trap which will injure innocent passersby cannot escape liability for his wrong by asserting that he has left the premises and no longer controls the injurious engine he abandoned to trusting mankind.
The proposition contended for by the additional defendant here was at one time the law of the land but
*428
it has disappeared with the horse and buggy and the rule that a husband is authorized to beat his wife with a stick no bigger than the thickness of his finger. The illustrious Justice Cardozo is credited with bringing about the change in the law which now holds the designers and builders of damage and destruction to a degree beyond that of mere contractual obligation. It was all well stated by Judge Hirt in the case of
Krisovich v. John Booth, Inc.,
“Beginning with Grodstein v. McGivern,
In
Bastl v. Papale,
Where a builder creates a hazard which, without the need of a prophetic telescope, proclaims potential injury to the public, he may not plead immunity from liability for resulting damage on the basis that his responsibility ceased with the insertion of the last bolt and the driving of the final nail.
In this case the Kaplan Company is charged with having constructed a pavement perilous to all feet which traversed it. Whether such a pavement actually came into being and whether, if it did, Kaplan was responsible for its lurking dangers, are questions of fact for a jury. The matters decided here are that under the pleadings in the case a noncontractual duty was owed by Kaplan to the plaintiffs, which duty was allegedly breached; the fact that this alleged breach also constituted a breach of the contract between Caldwell and Kaplan Company does not sweep away Kaplan’s noncontractual responsibility; and the fact Kaplan had completed its work and was not in possession *430 of the premises at the time of the injury is not a bar to the prosecution of the plaintiffs’ claim.
The judgment of the court below is reversed with a procedendo.
