14, 15 and 16 were erroneously dismissed. The State cross-appeals, contending that claimant’s recovery in action numbers 9 and 13 was improper. The present appeal raises five issues concerning the construction of the contract between the claimant and the State. We note at the outset that the court may not, under the guise of interpretation, make a new contract for the parties or change the words of a written contract so as to make it express the real intention of the parties if to do so would contradict the clearly expressed language of the contract
(Bodolitz v.
Neptune Paper Prods., 22 N Y 2d 383 ). Circumstances extrinsic to the agreement will not be considered when the intention of the parties can be gathered from the .instrument itself
(West, Weir <& Bartel v.
Garter Paint Go., 25 N Y 2d 535 ). The first issue raised on this appeal is whether the trial court erred in dismissing claimant’s “ Second ” and “ Third ” causes of action. In its second cause of action, claimant alleged that the State breached the contract by requiring claimant to install new ceilings in the center core of the office building. In its third cause of action, claimant alleged that the State breached the contract by requiring claimant to remove existing ceilings and ceiling materials from the center core and wings of the office building. Both of these two causes of action, which constituted the major part of the claim (seeking damages in the sum of $120,475), were based on the conflict between the claimant’s and the Stage’s understanding of the scope of work encompassed by alternate Proposal No. 2. As originally drafted, Proposal Nos. 1 and 2 read as follows:
“Alternate Proposals Separate proposals will be required for work of this Contract as follows:
Proposal No. 1 — If the Contract is awarded upon the basis of Proposal No. 1, it shall include all work specified and/or shown on the drawings.
Proposal No. 2 — If the Contract is awarded upon the basis of Proposal No. 2, it shall include all work specified and/or shown on the drawings except toilet rooms, first floor, new ceilings and pipe and duet closures in the entire two wings indicated as Phase II, Stage I, and the entire Tower indicated as Phase II, Stage II on Drawing 64/254 shall be omitted.” Subsequently, pursuant to Addendum No. 5 dated December 14, 1964, the wording of Proposal No. 2 was changed to read as follows:
“Alternate Proposals Change Proposal No. 2 to read as follows:
Proposal No. 2 — If the contract is awarded upon the basis of Proposal No. 2, it shall include all work specified and/or shown on the drawings except toilet rooms on the first floor, new ceilings and pipe and duet closures in the entire two-wings indicated as Phase II, 'Stage I and the entire tower indicated as Phase II, Stage II on drawing 64/254 shall be omitted.” The singular purpose of this change in wording was to clarify any ambiguity which might exist as to the work excluded under Proposal No. 2, specifically the work involving the toilet rooms. Instead of a comma after “rooms”, the words “on the” were added between “ rooms ” and “ first ” to plainly indicate that the “ toilet rooms on the first floor ”, and not
“ toilet rooms ” and the “ first floor ”, were not included under Proposal No. 2. No other change was made in Proposal.No. 2. Claimant contends that all the work on new ceilings throughout the entire building was excluded from the contract under Proposal No. 2. The trial court found that the only new ceilings eliminated under Proposal No. 2, by clear and unambiguous language, were the new ceilings in the wings. We agree. The work excepted by Proposal No. 2 is plainly comprised of three sections: the toilet rooms on the first floor, new ceilings
and pipe and duct closures in the entire two wings, and the entire tower. Claimant contends that the word “ and ” between
“ new ceilings ” and “ pipe ” in this clause was used by the draftsman of Proposal No. 2 in a connective as
