We are a small group of uniquely qualified professionals who conduct rigorous safety research, leverage new knowledge to create safety innovations, and experimentally test safety innovations on actual construction sites. All of our work has withstood the rigors of peer-review before being offered to the industry. We believe that construction workers deserve the same level of research rigor that is applied to other fields that relate to human health and safety and that 'good ideas' are simply not enough.


Our position is that safety beliefs are hypotheses to be tested, not truths to be guarded.

What we do and what we believe
