Mandatory pre -bid meeting: Contractors who did not attend the mandatory pre -bid meeting must schedule an appointment with the City Project Manager: Adib Attalla' Adib. _ tatlat Tukwila A..gov. 2. Q: Should the steel be primed and painted? A: Steel shall be primed and painted to match the walls, which are white. 3. Q: After relocating the sink, should the wall be repainted? A: After relocating the sink, the wall should be painted to match existing walls. 4. Q: There are conduits in the way, but no electrical sheets or clear notes. A: The contractor shall relocate the conduits to the nearest wall to avoid concrete demotion and accommodate the new steel support beams. 5. Q: For the floor cut to install the beam, should the cut extend fully to the rounded edge, or can it be squared off? A: The cut for the slab demo can be squared off. 6. Q: Should the beam be one piece or spliced? A: Due to the length of the beam, it needs to splice per design. 7. Q: Please confirm if pumps can remain in place during demolition. The notes are unclear, but it sounds like they don't need to be removed. A: Pumps must remain in place during demolition. There is no way to remove them before demolition of the slab. The temporary shoring must be installed to fit around the pumps and piping, and the contractor must prevent any concrete slab from damaging the pumps and pipes during cutting and demolition. Note: Bypass pumping will be required if all pumps must be shut down, or at least one pump must stay operational. 8. Q: Can the ducts in the way remain with reduced air volume, or must they be removed entirely? A: If the ducts can remain with reduced air volume, they may be able to be left in place. Otherwise they may need to be relocated. p,vK€RvI)24vEas E_IE-T TA1EON NO. 2 %IRU NC�INEERENGN3 ASSISTANCE \A I_?D1:INDA\ADDq\l.
