Rydman contends that the builder’s risk policy covers the loss of his vessel. He argues that the policy insures not only losses occurring during the policy period, but also losses occurring after the policy period when the operative cause of the loss, here allegedly defective construction, occurred during the policy period.
In resolving the issue whether this policy covers only losses occurring during the policy period, we turn to the rules of contract construction. Where the language of a contract is unambiguous, the intent of the parties and meaning of the contract are to be determined from the language alone, without resort to other aids of construction. Hastings v. Continental Food Sales, Inc., 60 Wn.2d 820, 376 P.2d 436 (1962); Boeing Airplane Co. v. Firemen’s Fund Indem. Co., 44 Wn.2d 488, 268 P.2d 654, 45 A.L.R.2d 984 (1954). “A written instrument is ambiguous when its terms are uncertain or capable of being understood as having more than one meaning.” Murray v. Western Pac. Ins. Co., 2 Wn. App. 985, 989, 472 P.2d 611 (1970); accord, Ladum v. Utility Cartage, Inc., 68 Wn.2d 109, 411 P.2d 868 (1966).
In our view, the terms of the builder’s risk policy are not ambiguous. It was clearly stated that “[t]his Policy insures only” during the policy period and within a certain geographical area. The key word is “insures.” It could not be stated more clearly that the builder’s risk insurers’ liability terminated outside the time and location limitations.
This construction of an unambiguous insuring agreement is totally consistent with the purpose for which the insurance was purchased. The contract between Rydman and Martinolich provided that Martinolich would maintain insurance until delivery. This insurance was to be “standard builder’s risk insurance.” The form on which the policy is written indicates that standard builder’s risk insurance was obtained — it is entitled “American Institute
