    • Successful litigation and mediated resolution of a project owner’s $8 million claim against its builder’s risk insurance carriers following two explosions and fires during the construction of a 250,000 sq. ft. data center in Washington County, Oregon. The builder’s risk insurers’ untimely and unreasonable claims adjustment resulted in zero payment to the project owner prior to Miller Nash’s involvement. Litigation involved extensive discovery of electronically stored information and depositions, in addition to summary judgment briefing and other motions. With the assistance of a mediator, the vast majority of the owner’s losses were recovered.

    • Guided healthcare system through forensic research, repair contracting, preservation of evidence, forensic expert reports, negotiations, and arbitration proceedings for damage claims against the general contractor and subcontractors that improperly performed exterior envelope, plumbing, electrical, and roof work to construct a new hospital for behavioral health patients and required specialty facilities. The entire exterior envelope had to be removed and replaced, together with removal and re-installation of all windows, while the hospital was occupied. After repairs were complete, we prepared, documented, and asserted claims to recover the owner’s damages. Following extensive discovery, depositions, arbitration proceedings, and mediation, we achieved a successful, multimillion dollar recovery of a substantial majority of the owner’s losses.
