CPWR Website Disclaimers

The Construction Solutions website and ROI Calculator website are provided at no cost to the user and are intended to provide useful information regarding safety and health hazards on construction sites and control options for reducing those hazards. Because of the constantly changing nature of conditions on a particular jobsite and in the construction industry generally, the effectiveness of any control must be validated on-site to assure that it provides adequate risk reduction. The Construction Solutions website is not intended to provide a comprehensive listing of hazards and solutions, and the examples in the ROI Calculator are only intended to provide information on the potential cost and/or savings based on case studies. Both websites are continually under development and, as CPWR - The Center for Construction Research and Training acquires additional information, it will change the material on a regular basis, without notice. CPWR is not responsible for errors or omissions on this website.

This project is funded by the National Institute for Occupational Safety and Health (NIOSH) cooperative agreement OH009762 and previously by NIOSH cooperative agreement OH008307. Content on these websites developed by CPWR is solely the responsibility of the authors and does not necessarily represent the official views of NIOSH.
