The relationships between the six subsidiary companies of MHS Legacy Group allows IWR North America to streamline their client’s supply chain and simplify their vendor base. From custom metal fabrication to scaffolding, IWR North America is a true building enclosure partner.


IWR’s safety motto is “If it’s not safe, don’t do it”.

IWR North America identifies safety as an investment and a commitment instilled within our company culture to provide a safe working environment for all employees. With this proactive mindset that safety is not a request but a condition of employment, success is achievable with one common goal: reach zero injuries on every jobsite.

Because of our strong foundation for safety, our standards are held at a higher regard because we expect our employees to be world class citizens providing world class service. It is our attention to safety, dedication to ongoing training, and quality workmanship that separates us from our competition. We make safety our number one priority.

Over the last several years, our experienced team has maintained an outstanding safety record with an EMR of .58.

We initiate this success for each critical phase of construction by implementing our behavior-based safety strategy, Standard Training & Orientation Program (STOP). With the award of each job, IWR develops a site-specific safety plan centered on this established corporate safety program.
