It isn't just worker safety that has improved in the last century, it's the safety of people in the building throughout its life. Building codes have expanded in scope and complexity over the years. Part of their scope includes installation method restricts and worker training and qualifications. The other aspect of it is general workplace safety regulations which have expanded over the years as well. When budgeting a project, you need to consider both, however. And workers also benefit from both. For example, the restriction on the use of asbestos in building insulation was brought in to reduce the health hazards of living or working in such a building but the construction workers handling the asbestos are clearly the most at-risk group which benefits from the regulation.
