There does not appear to be any mechanism to divert ventilation air from the VLP / Shafts areas away from the make-up air units (AHU-5, AHU-6). Mechanical gates are incorporated to ventilate either thru the blast dust collectors or thru the paint plenums, but air appears to be 100% recirculated at all times. Please confirm.

The intent is to send air from the recirculation fan discharge header, through the air handler return air damper, past the air handler fans, and back into the main air header that feeds the supply diffusers. The ratio of recirculated air to outside air would be controlled by the air handler return air damper and outside air dampers.
