The shaft is for exhaust of those hoods and must be continuous from the Basement to the roof. It is designed to work with existing structural members to avoid penetrating structural beams and ribs. New openings in the existing concrete slabs are required at the roof, Level 3, Level 2, and Level 1. The shaft location was selected based on known structural layouts, limiting impact to existing and Phase 1 program spaces, and avoidance of existing mechanical and electrical equipment which would be costly and time-consuming to relocate. New 2-hr fire rated shaft walls will be required around the interior sides of this shaft. The shaft requires some rework of the Phase 1 lab spaces on Levels 2 and 3, while still maintaining the desired program, and it reduces the size of an existing conference room on Level 1. On Level 2, it reduces the spacing between benches and would necessitate shallower benches at the east end of the open lab in order to maintain adequate walking space around benches and fume hoods. On Level 3, the E-Beam Deposition room 367F is reorganized but still contains the desired equipment. The impact on the Basement floor plan is minimal with only headroom needed for exhaust ductwork. On the roof, the exhaust ductwork would penetrate an open roof area and be connected over to the planned, Phase 1 exhaust fan equipment. Capacity:The new shaft down to the basement provides inside clear dimensions of approximately 1’-7” x 2’-5” (3.8sf). This can accommodate a 1500 CFM exhaust duct. The new exhaust duct would tie in to the Phase 1 exhaust fan system (EF-A.1 & EF-A.2) on the roof and then run down to the basement via the new shaft. A new supply air duct sized for 1500 CFM would connect to AHU-A in the basement. The supply duct would be installed in the future and is not part of the scope of this alternate. If the 1500 CFM capacity for supply and exhaust is used in the basement it will take away some of the capacity for future fume hoods and snorkels that was planned for levels 2 and 3. The area / quantity and program of the lab spaces in the basement would be constrained by the available CFM. To provide 8 ACH with 1500 CFM, the lab can be no larger than 1125 SF (with 10FT ceiling height). Within that lab, 1500 CFM could accommodate approximately (1) fume hood at 100 FPM face velocity (850 CFM exhaust) and (3) snorkels (200 CFM/each). If fume hood face velocity or snorkel flow rate were allowed to reduce, additional hoods or snorkels may be possible. Please also refer to the Memorandum provided by Vanderweil “Cornel Olin Hall Phase 1 –Basement Alternate MEP Narrative” dated 11/14/18. Impact to coordination and current MEP/F design:This option would require re-work of the E-Beam Deposition room HVAC layout on level 3. Supply ductwork, diffusers and piping would need to be shifted away from corner to accommodate new shaft. The layout of this room is very tight and the new layout may require the grid to be shifted and/or impact ceiling height. On level 2, the main supply air duct would need to be off-set via a 45 deg transition to avoid the new shaft in the corner. Nearest supply VAV may need to shift for new main routing. This option would require rework of plumbing piping in the E-Beam Deposition room to avoid new shaft location.
