We reject the landlord's argument that the tenant failed to prove a prima facie case. Based on the testimony that water sprayed all over the store and that the replacement pipe had ice on it and cracked almost immediately after it was installed, the jury could reasonably infer, without expert testimony, that the burst pipe was a water pipe that served the entire building within the meaning of the lease clause, imposing a duty to repair on the landlord. Causation was also sufficiently shown, with the testimony that it was cold that January, there had been no heat in the tenant's store since November and the day before the pipe burst was the first day in January above freezing, it being a matter of ordinary knowledge and experience that water in pipes can freeze in winter for of lack of heat in a building and that pipes can rupture when the temperature rises (see, Par-X Uniform Serv. Corp. v. Emigrant Indus. Sav. Bank, 268 A.D. 699, 702; Distribuidora Nacional De Disco v. Rappaport, 92 A.D.2d 559, 560).

In the absence of evidence, as opposed to counsel's speculation, that the tenant's installation of an insulation wall or removal of a small radiator prevented heat from reaching the subject pipe and contributed to its freezing, there was no basis for a comparative negligence charge (see, Nallan v. Helmsley-Spear, Inc., 50 N.Y.2d 507, 516-517). Nor was there a basis for a charge on releases, where the release contained in the parties' 1994 Civil Court stipulation, which stated that the tenant would look to the landlord's insurance company for payment of "any property damage claim," does not unequivocally express an intention to release the claims made herein (see, Blog v. Battery Park City Auth., 234 A.D.2d 99, 100), the landlord's insurance company refused to pay the tenant's claims, and the parties had obviously contemplated when they entered into the stipulation that the landlord had coverage. While the trial court erred in refusing to give a missing document charge with respect to the tenant's subpoenaed tax returns, the nonproduction of which the tenant did not reasonably explain (see, Cidieufort v. New York City Health Hosps. Corp., 250 A.D.2d 720; cf., Mathis v. New York Health Club, 288 A.D.2d 56, 732 N.Y.S.2d 341), the error does not warrant reversal where the landlord commented in summation on the tenant's failure to produce the tax returns and the tenant offered no response.

Damages based on the $16,500 estimate for redoing the tenant's floor should not have been awarded, there being no dispute that such work was never done. Nor should lost profits have been awarded based only on four months of operation (see, 676 R.S.D. v. Scandia Realty, 195 A.D.2d 387), and without proof of the profits of similar businesses in the area (cf.,Ciraolo v. Miller, 138 A.D.2d 443, 444; Trademark Research Corp. v. Maxwell Online, 995 F.2d 326, 333). We would also note that the jury's total award exceeded the ad damnum, the tenant never moved to amend its complaint (see, Reid v. Weir-Metro Ambulance Serv., 191 A.D.2d 309) and, contrary to the tenant's contention, it did not seek an increased amount in its bill of particulars.

THIS CONSTITUTES THE DECISION AND ORDER OF THE SUPREME COURT, APPELLATE DIVISION, FIRST DEPARTMENT.
