Condominiums—Construction Claims Against Sponsor, General Contractor, Subcontractors and Architect—Court Denies Motion To Compel Arbitration—Claims Were Inextricably Intertwined—A Contrary Decision "Would Create an Unworkable Fracture Between the Various Parties" and "Would Prolong the Litigation and Invite an Inconsistent Result"
