The "Built To Last Act of 2026" aims to enhance the resilience of infrastructure by requiring the identification and dissemination of forward-looking meteorological data. It directs the Under Secretary of Commerce for Oceans and Atmosphere to establish a consistent, federal set of best available long-term meteorological information. This information will model future extreme weather events , such as hurricanes and floods, and other environmental trends like rising sea levels, based on projections and observations. The bill further mandates the Director of the National Institute of Standards and Technology (NIST) to make this crucial information publicly accessible. NIST will also provide expert advice and technical assistance to organizations responsible for developing standards, model building codes, and voluntary certifications. The objective is to ensure these guidelines appropriately incorporate the forward-looking meteorological data, thereby improving the long-term durability and safety of structures against future climate challenges. A working group will be established to support the research and identification of this vital information.
