English Dictionary (1919). In this sense we speak of the surface of the ground, or of a lake, or of a highway. It is true that when the words are considered in their context and against the plans and specifications, a strong argument can be made for the proposition that by “surface included in the bridge deck,” the entire outer surface was meant, or at least something more than the upper surface alone. See Selectmen of Natick v. Boston & Albany R. R., 210 Mass. 229. The specifications indicate that the several surfaces of the deck, as well as its content, were of concern to the State. They provide with great particularity requirements for the construction of forms for “surface which will be visible,” for the curing of the “underside” and the “upper and side surfaces,” for the cleaning of “surfaces” and the protection of “surfaces” against cold. Without violence to the language used, it could reasonably be concluded that all of these surfaces were deemed a part of the “surface included in” the deck.
On the other hand, it was likewise readily apparent from the plans and specifications that the upper surface of the bridge approximated 4,000 square yards, or 4,600 square yards according to the plaintiff’s president. The plaintiff’s bid, as well as the defendant’s was made upon the estimated quantity of 3,933 square yards. While the proposal form furnished by the defendant, part of which was adopted by the plaintiff in its bid on Item 15a, did state that the estimate of 3,933 square yards was to be “used only for comparing bids,” and that actual quantities should control for payment, it also stated that the “estimate of quantities ... is approximate.” This provision might reasonably be taken to indicate that the bid requested and made, being upon a quantity which actually approximated the area of the top surface alone, was predicated upon payment for that surface only. In this view, a bid made upon an interpretation requiring payment for 8,100 square yards would not reasonably be considered a bid upon a quantity approximating 3,933 square yards.
The Trial Court’s conclusion that the “words in question are not so plain and clear that reasonable men could not differ as to their meaning,” when applied to the subject matter of the contract or the “state of the property” (Weed v. Woods, 71 N. H. 581, 583) was warranted. “[T]he 'ambiguity’ seldom appears until the attempt is made to apply the words to existing facts by the use of parol evidence.” 3 Corbin on Contracts 81, 82.
In this situation, the question presented was what the parties
