If you are limited by budget, space or programming, your team may want to find other ways to meet the shower requirements. Consider providing employees with gym memberships that allow them to take a shower after biking or partnering with other facilities within the same building that can provide access to showers (this approach is confirmed by multiple NC CIR rulings and a CI ruling from 2/12/07 for CI SSc3.2).  If pursuing gym membership or another alternate option, consult with GBCI about your approach and plan to write an alternative compliance narrative describing your approach and how it meets the credit intent and requirements.
