Owner provided in symbols legend. Design provides raceways for an owner provided system.

13. 2-16-23 From the site visit it appears the old addition was built “inside” or on top of the existing parapets walls? Drawing 01-A3 detail 1 indicates we are demoing the exterior walls including the parapet? Is this correct? This may affect the structural integrity of the building.

See photos below. See Attachment 1

Parapet wall is being taken down to the 5the floor slab/roof level, details are provided in our design. Building on top of the parapet wall was not feasible from either an architectural or structural perspective.

14. 2-16-23 Also drawing 01-A6 detail 2 wall section does not indicate the existing parapet, therefore, are we to assume we are removing the parapet? Or are we building the new walls on top of the existing parapet? See Attachment 2

The “Design Intent” is to remove the existing parapet wall where the new walls will be located.

https://www.armstrongflooring.com/commercial/en-us/products/het/nidra.html

15. 2-16-23 If the parapet is to be removed, we will need wall section views at the corners showing how the wall will tie to remaining existing parapet. See Attachment 2

18. 2-16-23 There is a roof drain just outside the exterior door of this space.

It appears water has entered this space before. How is this to be prevented in the future? Drawings do not indicate that roof drain being relocated, nor does it indicate we are to raise the interior floor level. Will the contractor be responsible for any damages due to water infiltration on new construction? See Attachment 3

GC should plan for a curb for a roof access door that is flashed/insulated.

Contractor is to construct a water tight structure.

19. 2-16-23 Are we removing the original existing cast in place concrete structure with brick and replacing with metal studs per detail 2-drawings 01-A6? See photo below. See Attachment 4

Any attachments will have to be removed prior to the carbon fiber being applied.

Confirm with carbon fiber group (Simpson) or (Fyfe) for specs. (or others) if anything can be attached after the application.

41. 2-17-23 It would appear from detail 1 on 01-A3 that the entire structure of 5025 removes down to the concrete floor deck including concrete roof support structure and seismic reinforcement that has been added to the original structure. Is this correct?

Yes

42. 2-17-23 Note D.7 on sheet 01-A3 calls for removing steel columns on 5th floor only. The site visit did not reveal any steel columns at this location. Please verify.

Columns are concrete, not steel, and they do require removal.

43. 2-17-23 Detail F1 & F4 on 01-S2 do not agree with the same location detail 10 on 01-A6. Site visit could not verify where the above parapet is located in relation to these details. Note 21 below may clarify this point.

Use details F1 &F4 on the structures drawing.

Structural elements shown on architectural drawings are for reference only.

44. 2-17-23 In reading the superstructure note in the synopsis, two existing concrete columns will be used for the structural steel attachment. If all the existing concrete structure is removed from around them, will not the structural integrity of the remaining columns be compromised?

No because the new steel structure attaches to the existing concrete columns, temporary bracing may be required per GC means and methods.

45. 2-17-23 If item 13 is correct, how can detail F4 on sheet 01-S2 be used as the attach detail for the structural beams on detail C8 same page.

Assuming that RFI 45 refers to RFI 44. Detail F4 shows the connections to the new steel columns.

46. 2-17-23 If item 13 is correct, what is the intent of demo note D.8 to “remove existing window and prep opening for new window.”

This would impact the exterior seismic & masonry finishes because the top of new window ht. is 7’-6” A.F.F.

The existing walls are to be demolished completely, this includes the windows

47. 2-17-23 If item 13 is correct, how can the new movable partitions be suspended from the existing concrete structure as indicated on the synopsis?

Partitions are hung from the new structure.

48. 2-17-23 Can there be a plan sheet of the original design or as-built drawings supplied that shows the area of 5th floor “C” wing for reference.

See plans attached for reference only. Field verification is required as actual conditions are unknown.

49. 2-17-23 Can there be a crosscut section both directions in rooms 5025 & 5025A showing the extent of demolition as it relates to existing conditions.

Wall sections provide needed details.

50. 2-17-23 What is the size of the existing concrete columns that the new steel is called for to be attached to and how close to the edge of the concrete can holes be drilled?

Existing concrete columns must be field verified.

Design shows anchor spacings.

51. 2-17-23 Can the exterior access to the MRI building be closed except for emergency exit only, for the duration of the needed demo and masonry construction of the wall immediately above this area. Free public access to this door will create a safety hazard even with a covered walkway.

No access will not be closed. Overhead protection required.

52. 2-17-23 Will the walkway between “C” wing and building 20 be closed for the duration of the project?

Yes for the duration of 5025/A construction.

53. 2-17-23 Can dump carts be used in lieu of a debris chute to the dumpster?

54. 2-17-23 In the project synopsis, please explain the requirement for 10% overages in all materials specifications.

General project requirement

55. 2-17-23 In the project synopsis, phase II demolition notes, please identify item #7 “demolish non- structural wall components”;

item #10 “remove ceiling components”; item #11 “demolish roof components” and item #12 “demolish structural components.”

No longer relevant with complete demo of the area shown on the plans.

56. 2-17-23 Where is the proposed location of the negative pressure ICRA barriers needed inside the Medical Center and outside the construction area.

Locations to get coordinated with COR.

57. 2-17-23 Will the new RTU-2 mount on the same roof supports as the one being removed?

Depending on the unit manufacturer and with modifications, the existing mount can be reused and must meet seismic requirements.

58. 2-17-23 Is there an existing roof support for RTU-1? If not, can we have a detail showing the approved mounting method.

There is no existing structure. Mounting should be per manufacturers specification and must meet seismic requirements.

59. 2-17-23 Window spec calls for single hung and plan indicates double hung. Which is correct?

Color to match, size is shown in drawings. If single window is available, that is preferred, otherwise units mulled together to equal opening are ok.

60. 2-17-23 Are there any marker boards furnished or installed by the contractor? Sheet 01-A4 seems to indicate marker boards on the operable partitions in 5025A.

Coordinate with COR during submittal phase.

Operable partitions shall have full height marker boards as indicated.

61. 2-17-23 Are the windows openings divisible in one unit or separate units mulled together to equal the opening? Please show an elevation view of the intent and size of the division. Also, the color.

Color to match, size is shown in drawings. If single window is available, that is preferred, otherwise units mulled together to equal opening are ok.

62. 2-17-23 Is there any special glazing required for the window units? No

63. 2-17-23 Can you please clarify the detail #10 note on sheet 01-A6 which states “verify the structure, dimensions and materials of existing wall structure?” We are not privy to that information and the site visit was inconclusive.

Contractor will need to refer to the existing drawings provided by the VA. Current existing conditions cannot be verified until demolition. Contractor’s means & methods shall apply while any coordination questions will be reviewed by the design team.

64. 2-17-23 For the finish schedule in each room, please show a basis for design including color, to be used for the suspended ceiling tile panels, sheet flooring and cove base.
