Please join NRMCA and guest speaker Tara Blank, Ph.D., from Elixir Environmental on Thursday, September 22, at 1 p.m. Eastern time who will provide ready mixed concrete producers guidance in developing Health Product Declarations (HPDs), and the challenges one can experience at each step. Although several prominent architectural/engineering consulting firms are already requiring HPDs for product specification beginning in October 2016, LEED v4 project teams will be requesting information from suppliers about the hazards associated with their material ingredients.
