Recognitions & Distinctions

Representative Experience

  • Assisted clients with claim preparation, document and damage tracking, and preserved the clients’ rights during actual construction of countless projects to obtain amicable resolutions and avoid litigation. These projects included bridges, tunnels, highways, tunneling and sunken caissons across the country.
  • Ingerman Affordable Housing v. Langan Engineering & Environmental Services (American Arbitration Association, 2014). Successfully defended alleged breach of contract and professional malpractice claims arising out of the development of a Brownfield, located in Jersey City, NJ.  The developer claimed that, because the contractor had needed to export more than 10,000cy of contaminated material, Langan must have erroneously represented the site as being generally balanced.  Successfully proved that the developer’s construction arm knowingly subcontracted with its earthwork contractor to utilize and spread 10,000cy of recycled concrete aggregate on-site for surcharging material without any thought as to the impact and need to then export an equal volume of on-site contaminated material.  Arbitration Panel ruled that Plaintiff’s claims were entirely without merit and frivolous and awarded Langan its defense costs and fees.
  • Intercounty Paving Associates, LLP v. PennDOT, (Board of Claims, 2009). Recovered three-quarters of a million dollars on behalf of the contractor in delay damages caused by PennDOT’s active interference, misrepresentations, defective plans and specifications, and its failure to recognize the legitimate financial interests of the contractor. Overcame no-damage-for-delay exculpatory language in the contract as well as PennDOT’s defense that the contractor was required to “coordinate” utility relocations.
  • Schiavone Construction Co., Inc.  v. MTA, (DRB, 2008). Achieved multimillion-dollar recovery on behalf of the Design-Builder for chemical grouting work directed by the Authority’s Engineer on a new subway station located forty feet below sea level in Battery Park, New York, New York.  Proved that the Authority — despite its post-contractual spin of defective work and deficient notice defenses – prescribed the waterproofing materials and other material design requirements that the Design-Builder was mandated to follow and incorporate into the “final” design; knowingly structured the contract to reimburse the Design-Builder for actual costs incurred for chemical grouting as “extra work”; directed bidders to estimate a prescribed amount of chemical grouting for bidding purposes as a baseline to evaluate bids and to keep all bidders on a level playing field; and contemplated that the actual amount of chemical grouting required would be determined by the Authority’s Engineer based on actual field conditions.  At trial, the Authority’s Engineer admitted that the aforementioned procedure was established because of the complexity and location of the new structure (sited between and under existing subways) and the unknowns associated with actual volumes required for injecting chemical grout in structures well below the water table of the adjacent Hudson River, Hudson Bay, and East River.
