For example, should a concrete structure collapse, either at a jobsite or once the building is occupied, falling concrete could seriously injure anyone who is nearby. Life cycle assessments show that wood outperforms both steel and concrete in terms of energy, air pollution and water pollution. According to the softwood lumber industry, “Mass timber buildings are roughly 25% faster to construct than concrete buildings and require 90% less construction traffic.” Amazing article on the advantages of concrete roads!
