Reported CasesSignificant Representative Matters: Mediated a favorable settlement of less than $1M for an Architectural firm in a high rise to condominium conversion project wherein the Owner claimed damages in excess of $4.5M for delays and cost increases caused by Architect errors & omissions and negligent construction administration. The result was obtained at mediation in part due to use of document management and search technology through which it was argued that the results showed that Owner had intentionally withheld or destroyed some pertinent documents that were likely favorable to Architect and went against Owner's credibility; Mediated a favorable settlement for a large Architectural firm that involved construction of an addition to a county prison. The County claimed $4.6M in damages for delays and cost increases, mostly due to negligent construction administration. The Architectural firm had formed a joint venture. Negotiations resulted in a $2M settlement, to which our client only contributed $300K as we were able to show that the substantial majority of the damages claimed pertained to the scope of activities performed by the joint venture partner; Successfully obtained summary judgment dismissal of an architect on the Statute of Repose in a deck collapse/personal injury action where the settlement demand was $2.5 million; Mediated a favorable settlement for an engineering firm in litigation that involved construction defect and delay claims in multiple projects for a chain store owner.
