This is an action, with a count in contract and one in tort, by which the plaintiff, a veterinarian, seeks to recover the various damages sustained by him by reason of the failure of a heating system installed by the defendant in a building on the plaintiffs property in
The heating system in question was of the forced hot water type, with horizontal circulating hot water pipes to be located under a concrete floor and with vertical risers leading from those pipes to radiation units attached to the walls of the building. There is no dispute that the principal, if not the sole, causé of the failure of the system was that the concrete for the floor was poured directly on top of the horizontal pipes and directly against and around the vertical risers without making adequate provision for the expansion of the pipes and risers which was bound to and did occur as hot water was circulated through the system. The stresses caused by the expansion of the pipes and risers directly against the concrete caused the system to leak in several places, and so badly that ultimately the floor had to be torn up and the entire system replaced. There was evidence, elicited from an expert witness for the plaintiff, that adequate provision for expansion could have been made either by the defendant in the course of installing the pipes and risers or by the masonry contractor prior to the pouring of the concrete.
We do not know who may have recommended, selected or designed the system. We do know, from the plaintiff’s own testimony, that in the course of the renovation of the building he acted as his own general contractor in the sense that he hired individual people to do individual responsible jobs and kept to himself the work of coordinating the various jobs which had to be completed. Both parties knew that a concrete floor was to be laid. The written agreement between them, while providing that “all material and equipment shall be
It was for this reason that the plaintiff offered evidence, which was received over the objection and subject to the exception of the defendant, to the effect that it was the custom of the trade that the heating contractor take the steps necessary to provide for the expansion of the pipes and risers installed by him whenever a concrete floor was to be laid. That evidence should have been excluded for the complete lack of any proper foundation, as there was no evidence that any such custom of the trade was sufficiently widespread or generally understood in or around Ipswich at the time of the execution of the agreement that the parties could be said to have contracted with reference to it. See Scudder v. Bradbury,
On similar reasoning, it was error to allow the answer to a question whether a heating contractor who had not made provision for expansion of the pipes and risers installed by him had performed his work in a good and workmanlike manner. The question was predicated on the impermissible assumption that a custom of the trade imposed a duty on the defendant which had not been' imposed by the written agreement.
The count in tort also refers to the written agreement and alleges that the defendant was “negligent, careless and unskillful in the performance of its work under the said agreement.” The defendant’s duty arose out of and was to be measured by the terms of the written agreement (Abrams v. Factory Mut. Liab. Ins. Co.
The plaintiffs exceptions to evidentiary rulings all relate to the exclusion of questions relating to the amount of damages sustained by him. As none of the answers sought would have supplied any of the deficiencies in the proof on the issue of liability, we need not consider those exceptions.
Such of the defendant’s exceptions as have been discussed in this opinion are sustained; the plaintiff’s exceptions are overruled; judgment is to be entered for the defendant.
So ordered.
Notes
The plaintiff concedes in one of his briefs that “ [t]he contract itself does not deal expressly with the question of who will be responsible for providing for expansion of the pipes.”
