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.

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.

Here is a look at a current healthcare project we are actively working on, showcasing our expertise in complex glazing, interior systems, and construction coordination—the CentraCare Plaza Expansion in St. Cloud, Minnesota. We are collaborating closely with RSP Architects (Minneapolis) and McGough Construction (St. Paul) to help bring the CentraCare Plaza Expansion design to life. From the outset, their project teams carefully factored the complex functional and operational requirements of expanded outpatient and specialty care into the overall design, ensuring each building system supports both architectural intent and long-term performance.

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. We worked closely with the RSP and Cobeck project teams to bring their design goals to life through a refined, high-performing ceiling solution.

We are pleased to highlight two recently completed ZONA® LYNX telescoping glass wall projects, each tailored to the specific functional demands of its space. Working closely with the architects involved, we helped bring each project's design vision to reality, delivering precision ZONA installations that support flexibility, transparency, and long-term performance across both professional office and high-traffic environments. Both projects feature 3/8" clear laminated glass with a clear anodized finish, providing a consistent balance of durability, safety, and refined aesthetics. Below is a brief overview of each project and the unique advantages the ZONA LYNX system brings to each application.

Most building professionals know that air leakage is one of the biggest performance failures in commercial buildings. What is less understood is this: Air leakage doesn't move in only one direction. It can move inward (infiltration) or outward (exfiltration) — and each direction carries its own set of energy, comfort, and moisture-control consequences. Even worse, rolling doors have historically been among the weakest points of the building envelope.
