W. L. Hall Company's Exceptional Experience Modification (MOD) Rate 

w. l. hall company premier exterior and exterior systems provider in the upper midwest mod rate

The W.L. Hall Company is extremely proud to report that our 2022 experience modification (MOD) rate is at an all-time low of .66. We have worked extremely hard to implement a culture that is focused on safety throughout the entire organization. Despite record hours in the field the changes we have made and the directives we have implemented continue to pay great dividends. 


A experience modification (MOD) rate contributes to how much companies pay each month in workers’ compensation premiums. It is partly determined by the industry classification in which a company operates and how many OSHA recordables it accumulates. If a company’s MOD rate is 1.0, they pay the industry’s average rate.

The experience modification (MOD) rate plays a critical role in many U.S. commercial construction bidding scenarios. Although the MOD rate is primarily used to calculate workers' compensation insurance premiums, it has been widely adopted by federal, state, and local agencies to evaluate the job site safety records and risk potential of contractors and construction companies that are bidding on projects. Many government agencies require documented proof of the MOD rate for bid submissions and use it as a factor in the selection process. Even more important, a high MOD number may disqualify contractors from submitting a bid in the first place.

In close collaboration with Anderson Engineering of Minnesota (Plymouth) and Greenstone Construction (Fargo), our team is helping bring their project design vision to life at the new Women’s Clinic at the Minneapolis VA Medical Center. As we near completion of this project, we are delivering a highly specialized glazing package engineered to meet the rigorous performance and security requirements of Department of Defense (DoD) design standards. This project required far more than a conventional façade solution—it demanded a carefully engineered system capable of balancing security, performance, and architectural intent within a blast-mitigated environment. The completed VA Women’s Clinic will provide a wide range of healthcare services specifically for women Veterans, including primary care, whole health, mental health, reproductive health, and specialized care for conditions related to military service. The new facility is thoughtfully designed to centralize all women’s healthcare services in a dedicated location, with its own exterior entrance to enhance accessibility, privacy, and the patient experience.

Luminous Barrisol® ceilings and walls use color-changing LED technology to shape atmosphere and support how a space is used throughout the day. Neutral tones suit everyday operations, while richer brand colors can highlight events, milestones, or special moments. Warmer hues create a welcoming feel for evening use or guest receptions, with digital controls allowing lighting to evolve as branding or needs change—without physical alterations. Extending the same approach into the vertical plane, Barrisol® luminous walls are built on a lightweight aluminum framework, with integrated lighting and translucent membranes. The result is a clean, softly glowing architectural surface that delivers uniform, glare-free illumination and visual calm. When ceilings and walls shift color in sync, the space gains depth and rhythm, subtly reinforcing brand presence and guiding movement through key areas without relying on signage.

For the executive conference room hallway at Boston Scientific Arden Hills, (Building 5, Floor 3) RSP Architects (Minneapolis) and Cobeck Construction (St. Paul) project teams established clear priorities from the outset: to create a visually striking, polished ceiling experience appropriate for a high-visibility executive corridor, while also providing effective acoustic sound absorption to control noise transfer from the adjacent conference room.
