Patrick J. Duffy, III is nationally known in the highly specialized field of heavy engineering construction law. A senior partner in Monteleone & McCrory, he has focused on civil business litigation for more than 30 years, representing prime contractors, subcontractors, design professionals and owners in disputes arising from major projects such as highways, subway systems, bridges, wastewater facilities and industrial plants in California, throughout the U.S. and internationally.

Mr. Duffy also represents contractors and developers in construction defect and other litigation in the residential real estate sector. In addition, he has represented clients in a variety of business-related disputes before both state and federal courts in almost every county in California. Experienced in jury trials, he also practices at the appellate level and is admitted to practice before the United States Court of Federal Claims. In addition, he has argued before international tribunals on behalf of governments and business owners.

Mr. Duffy has substantial experience in preparing and organizing the voluminous records commonly involved in complex litigation. He also is adept at presenting highly technical scientific information in a way that makes it understandable to a jury.

Mr. Duffy’s experience includes:

  • Obtaining a jury verdict resulting in a judgment in excess of $40 million against a large charter city. The judgment included a return of all liquidated damages and an award of 100% of the contractor’s claimed project delay damages. The jury also specifically found that the city’s actions were unreasonable under Public Contract Code section 7107 leading to an award of penalty interest at 2% per month on the withholding totaling over $15 million;
  • Obtaining an award by the State Office of Administrative Hearings on a freeway project for a small contractor who had lost bonding capacity because of the owner’s actions which award completely exonerated the contractor from the default declared against the contractor and awarded damages that will make the contractor whole again. The award also found that the owner’s actions violated Public Contract Code section 7107 and an award of penalty interest at 2% per annum plus an award of attorneys’ fees incurred in the case is now pending;
  • Defending a cement company owner and the government of Indonesia against a contractor in an international arbitration, and acting as a mediator in a dispute between a contractor and the government of Equador;
  • Obtaining a reformed agreement for the seller of a Hollywood property based on the buyer’s deceptive contract language and sharp dealing that would have cost the seller several million dollars had the agreement not been reformed;
  • Convincing a jury of a contractor’s innocence in an alleged criminal public safety violation matter;
  • Successfully defending a major designer of large projects in the Western U.S. against design deficiency claims while successfully advancing extra work claims;
  • Achieving a 2 million dollar settlement for a prime contractor on a 2 million dollar claim for damages caused by fraudulent representations relating to the design of an excavation support system causing a subsequent shaft failure;
  • Winning a 2 million dollar award for a construction company in a highly publicized dispute involving cost overruns on the Venice Canal refurbishment project;
  • Achieving successful settlements of approximately 25 million dollars and 20 million dollars for a public works contractor that built sewer treatment plant upgrades from faulty plans provided by a public entity owner which owner settled rather than face the case prepared to be presented to the jury against the owner;
  • Winning a 2 million dollar arbitration verdict for a manufacturer accused of late performance in the delivery of goods sold which award also included 100% of the attorneys’ fees and costs expended in the case;
  • Winning a 6 million dollar jury verdict after an eight week trial against a water district for a contractor in a dispute that arose from an eighteen month overrun in the time of construction of a new water treatment plant; and
  • Obtaining the agreement of a public agency in a mediation to forego all liquidated damages and, instead, pay the contractor its costs for the delays to the completion of a major hospital project.
