Order, Supreme Court, New York County (Joan A. Madden, J.), entered July 1, 2015, which granted plaintiff’s motion for summary judgment dismissing defendants’ counterclaims, unanimously affirmed, without costs.

The affirmation of plaintiff’s attorney, as well as the contract between the parties and related documents were properly submitted in support of plaintiff’s motion, regardless of whether the attorney had first-hand knowledge of the underlying facts (see

Olan v Farrell Lines, 64 NY2d 1092 [1985];

Furlender v Sichenzia Ross Friedman Ference LLP, 79 AD3d 470 [1st Dept 2010]). Based on the plain language of the contract, plaintiff was only responsible for interior design work, and was not responsible for any work or service provided by any other contractor or subcontractor. Thus, plaintiff was not responsible for the alleged damages defendants incurred based on the improper demolition work performed by a nonparty contractor, hired by defendants to work at the renovation site (see
