My CS v4 project wants to pursue Enhanced IAQ Strategies but we are not responsible for installing entryway systems or walk-off mats. The tenant will be installing the depressed slab for entry systems and/or walk-off mats as the floor will not be finished by the CS team. Since this is out of scope for the CS team, can we comply by using a signed TSLA? In v3 I was under the impression that the core and shell team must build out the entryway systems to achieve IEQc5, although that is not clear for v4. If the core and shell scope of work does not include building out the slab, then we feel we can comply through the signed TSLA.
