Will existing panels in electrical rooms 122A and 135E be able to be shut down in order to tie in new circuits? If so will this have to be done after hours? This is asked for safety reasons. Refer to general demolition notes no. 2 on E001. 7. Are the ceilings in C wing corridor all the same height? Are they all drop ceilings? This is in reference to the installation of the network and security riser conduits. Yes these are all drop ceilings. 8. Can required core drilling be done during normal hours? Core drilling being performed in Bldg. #1 to be performed after hours. Core drilling Bldg. #20 can be performed during normal working hours. 9. I reviewed the panel directories on the E drawings and don t see where the new VAV boxes are being fed from. Please let us know where they are originating from and can they all be daisy chained together on one circuit? Refer to 20-EP104B and 01-EP101 for VAV power information. 10. Will the new VAV s need disconnects at the unit? VAV s mentioned above specify LV power from power supply. However, if control contractor decides that to change and feeds line voltage (120V) to each VAV, then yes, disconnects will require at each VAV unit. 11. The wood door spec is calling for us to provide only lite cut out and metal vision lite kits no glass. It is unclear, as least to me, if they want rotary cut wood doors (no species listed) pre-finished or paint grade wood doors. Please clarify. The glazing spec is also not clear as to the type of glass let me know if you want glass other than the standard glass we d normally supply with doors like these. Rotary Cut Wood Doors Silver Maple - Prefinished, finish TBD Non-rated doors are noted to have MG-1 glazing per door schedule. 12. Please see the panel I have highlighted. There is no panel in the electrical room with that designation. 13. On 20-EL104 they are calling for 3-way and 4-way dimming switches. We have run into trouble in the past with these being on the drawings and then not being able to get the proper switches that dim. Can you please clarify a manufacturer or style that they used as basis of design so we can make sure they will work? Refer to drawing E602 for lighting control basis of design notes. 14. 1) In the typical casework photo (7/20-Q104.6), the mobile cabinets. MC-1 appear to have tops. - Are tops required on the mobile cabinets or should the top of the cabinet be finished? - If tops are required, are the plastic laminate? Tops are not required on mobile cabinets. 15. In the same photo, the adjustable wire mold appears to be the full length of the work station but in the elevations (TYP. 1/20-Q104.6) each unit has its own 4 or 5 wire mold. - Where there are 3 workstations side by side, should there be 3 separate wire molds or one continuous wire mold? Each workstation will have wire mold with 3 duplex on it. out of which 2 duplex will be connected to normal power and one red color duplex will be connected to critical panel. 3 workstations side by side will have total 18 duplex (3 duplex times 6 work station). Contractor shall wire a group of 6 outlet together and provide cord with twist lock male plug. Provide matching female twist lock outlet mounted in ceiling inside service pole. Each female twist lock will be connected to dedicated 20A circuit to normal and critical panel as shown on drawing. - What is the source for power to the wire molds? Refer to 20-EP104A Ketnote 1 and panel circuit legend 16. Are the table frames adjustable or fixed height? The photo, the frames look fixed, however, on the elevation drawings they look adjustable. Adjustable 17. Laboratory Casework specs call for wire pulls but the elevations and photo appear to show full width pulls. - Are wire pulls acceptable as long as they meet the spec requirements or are full width pulls required? Full length pulls will be preferred 18. P-Traps are included in the Countertops specs (12 36 00), but these are typically furnished and installed by the plumbing contractor. - Who is responsible for furnishing and installing the p-traps, casework or plumbing contractor? Plumbing Contractor 19. Based on our initial interpretation for the three micropiles located on drawings number 20-S-401, it appears that the piles are too close to the existing one-foot thick existing concrete wall to allow for drill rig access. Can the micropiles be stepped back from the existing concrete wall? Our drill rig needs at least 2-3 of clearance in front of the rig. This is because the drill rig jaws extend farther in front of the rig than the actual drill location itself. This will result in the jaws hitting the existing concrete wall. The location is set based on pile cap design and position in relation to the connection above. They should not be stepped back.
