Researchers at the Concrete Sustainability Hub at the Massachusetts Institute of Technology have been hard at work on a new method for analyzing the life-cycle cost of construction materials. The approach uses statistics to provide decision-makers with a probability of the future cost of materials based on the cost changes in the past. “Those who are cost-averse can base their decisions on the history of price volatility of one material or another. The model provides the likelihood that this or that will happen,” says professor Franz-Joseph Ulm. This, says Ulm, will allow fiscally responsible planning for urgently needed infrastructure repair.
