William Pirk defends project owners, contractors and design professionals in a variety of claims arising out of personal injuries, property damage and defective construction. He handles cases ranging from simple slip and falls to wrongful death claims; minor property damage to million dollar water infiltration claims; and defective retaining walls to entire condominium complexes.

Prior to practicing law, Mr. Pirk spent more than 20 years working in the construction industry. While in high school and college, he worked summers as a carpenter on commercial construction projects. Following college, where he earned a degree in civil engineering, Mr. Pirk continued to work for a commercial construction company in the New York City area, initially as an estimator, later assuming the duties of a project manager, and eventually becoming a vice president.

  • Dismissal on appeal of all claims brought by a construction worker injured when the wall he was instructed to cut into collapsed on him, fracturing his leg. Bill argued that the work plaintiff was performing was not “demolition” as defined in New York’s Industrial Code.
  • Dismissal on appeal of all claims against the owner and general contractor when the conduit he was installing fell, fracturing his orbital socket. Bill successfully argued that, although the plaintiff had placed the conduit over his head before it fell, it was not a material that was being “hoisted or secured.”
  • Dismissal on appeal of all Labor Law claims brought by a painter who was injured when the ceiling he was painting suddenly collapsed, causing him to fall off a ladder.
  • Partial summary judgment in favor of the owner and general contractor in a wrongful death claim where the decedent was crushed by a concrete slab that was intentionally dropped, dismissing all claims under Labor Law § 240(1) and 200, as well as all claims for conscious pain and suffering and per-impact terror.
  • Summary judgment in favor of a private engineering firm retained by an incorporated village to conduct inspections of a new condominium complex, which was later shown to have been defectively constructed by showing that the purchasers were not third-party beneficiaries of the village’s retaining agreement.
  • Summary judgment in favor of an engineering firm retained to design a seawall enforcing the limitation of damages provision in the retaining agreement when the sea wall was found to be defective. The resulting cost to cure the defect would have greatly exceeded the engineer’s fees
