The Associated General Contractors of America's BIM Forum is formulating the 2013 Level of Development Specification for building information modeling. "The overarching goal is to enhance the predictability of outcome while reducing the disappointment of unmet expectations," says Ronald Dellaria, a member of the all-volunteer LOD Working Group and chief compliance officer of design-build firm Astorino. Development of the spec is "designed to drive efficiencies into the BIM process and remove uncertainty by enabling teams to specify a deliverable against a universal standard."
