35. Question: What is the depth of the existing slab on grade at the basement and on grade areas of the 1st floor? If unknown, what depth should we assume for bidding purposes?

Answer: Basement and 1st floor slab on grade depth is unknown. We have drawn and assumed 5" based on conversations with building maintenance and experience with similar buildings.

36. Question: The notes indicate to re-use existing MEFP floor and wall openings as much as possible. Our assumption is that all the holes will not be re-used. How many floor openings and wall openings should we assume will need to be patched for bidding purposes? Please provide a detail for patching of floor penetrations.

Answer: Unused floor openings should all be patched. For floor openings in structural vaults see 1/S-104. Refer to A-900-906 for floor finish occurring above patching. For limestone flooring use non-shrink grout tinted to match adjacent surface. A mock-up will be required to determine the patch is acceptable. (assume 22 patch surface & 148 patch beneath new floor finish) Wall openings in basement, above ceiling, or in utilitarian spaces can be left open.

37. Question: Reference note 2.05 on drawing AD-202, 203 will we be responsible for display removal, or will this be handled by a separate package. Our understanding was that all display work was going to be a separate bid package and that we were not supposed to include this item in our bid per the initial GC walk thru.

Answer: Display removal will be done by NPS.

38. Question: Reference keyed note 2.13 at southwest wall in room 122, please confirm that this wall is to be completely removed. The wall is shown with solid lines and does not have the dashed lines that all the other walls with this note have. Is this a utility chase that will have to have a portion of the wall removed for MEFP access?

Answer: Note 2.13 that points to the solid grey wall is incorrect, the masonry chimney located there will remain.

39. Question: Reference note 2.23 in room 109, 111 on drawing AD-203, please confirm that this bid package is not responsible for the salvaging or re-installing of historic wood divider.

Answer: Project scope includes removing and returning to NPS but not reinstallation.

40. Question: Note 2.31 on AD-302 directs for the higher ceiling of the first floor to remain in the rotunda area, which contradicts what the hatch depicts. Also, the hatch on A-302 shows new gyp board on existing frame. Please clarify scope extent.

Answer: This ceiling area should be removed, and new gyp board installed on existing framing.

41. Question: Reference notes 2.03 and 2.30 on drawing AD-302, both notes call for the plaster ceiling to be removed. Note 2.30 calls for the ceiling to be removed to the structure. Is there an additional ceiling above the plaster ceiling that needs to be removed? We are trying to figure out what additional work is required for note 2.30 verses note 2.03. Does the 2.30 note represent barrel vault plaster ceilings?

Answer: Some spaces have original ceiling structure, design intent is for plaster or gyp to be removed but the ceiling structure to remain for reuse with new gyp ceiling.

42. Question: Who is the Ameren point of contact for the new vault work?

Answer: TYLER A. CLARKE, P.E.

Supervisor, Distribution Services (Underground) Underground Division Mail Code 678 C 618.401.3134 T 314.554.2633 E Tclarke@ameren.com

43. Question: Please provide appendix H, which was issued with the original documents but did not appear in the updated solicitation documents. Are we responsible for abatement that is identified, but drawings do not indicate the product being removed. Example: the reports indicates that there is asbestos containing flooring in numerous rooms, but the demo drawings call for the flooring to be removed in those rooms. We will need a document that specifically tells us how much abatement work is required on the project and the quantities that we should assume for bidding purposes and where the abatement work is located in the building.

Answer: Appendix H is included in Volume 4/Project Manual.

44. Question: Are we responsible for new signage on the project?

Answer: Yes, there is a separate CLIN 3 for the wayfinding signage scope, as noted in the Contract Price Schedule. Refer to Appendix G for the Signage/Wayfinding drawings and the spec section. 101400.

45. Question: Reference equipment being removed from basement, will we be responsible for removing equipment pads that the equipment sits on? Examples: condensing units and generator being removed from basement.

Answer: When outdoor condensing units are removed, those setting on pads will need pads removed as well. The existing pad for the natural gas generator will need to be removed and a new one provided for the new diesel generator.

46. Question: Reference demo notes 2.03 and 2.31 in room 220 on drawing ad-304, note 2.03 says to remove ceiling to room extents, and note 2.31 says the existing ceiling is to remain. Please clarify what the ceiling demo scope is required in room 220.

Answer: Note 2.03 applies to extents of flat lower ceiling. 2.31 applies to extents of higher vaulted ceiling.

47. Question: Is there a specific reason a Hydraulic Elevator was selected? We are foreseeing some possible constructability issues with digging the elevator pit as well as boring a hole for the elevator jack. Is a machine room-less traction elevator an acceptable alternative?

Answer: There is limited room between the existing floor to floor height at level 2. The hydraulic elevator avoids the additional floor demolition that would be required for a traction elevator.

48. Question: STN-4 is shown on sheet A-904 in the storage rooms but is not included on the finish schedule/index. Please confirm there is no scope with STN-4. If there is, please provide specifications similar to what is included for STN-1, 2, & 3 for STN-4.

Answer: STN-4 should match STN-1.

49. Question: Will there be an Emergency Responder Radio Communication System included in this renovation.

Answer: Wood window frame repairs only occur at windows defined as BASE and C.O.1. Windows labeled NIC will have no frame repair or sash replacement but will have work required by the Window Notes 1-9.

64. Question: Our interpretation of the answer of RFI #28 is that all windows noted as “BASE” or “C.O. 1” and have details associated with sheets A-803, A-804, A-805, A-806 on sheet A-801 are to have their sashes replaced with new manufactured/replicated sashes in their entirety.

Amendment 5, issued 8/25/20:

75. Question: The SBA issued a final rule that was effective on 1/23/17 that allows counting of lower-tier subcontractors (https://www.govinfo.gov/content/pkg/FR-2016-12-23/html/2016-30874.htm). The Code of Federal Regulations contains the new provisions in Title 13, Chapter I, Part 125 – 125.3(1)(i)(C): https://www.ecfr.gov/current/title-13/chapter-I/part-125/section-125.3. Per the revised CFR, will we: a. be allowed to establish two sets of small business subcontracting goals, one goal for the first tier and one goal for lower tier subcontracts awarded by other than small subcontractors with individual subcontracting plans? b. be allowed to establish two sets of small business subcontracting goals, one goal for the first tier and one goal for lower tier subcontracts awarded by other than small subcontractors with individual subcontracting plans?

Answer: The rule / reg allows Prime contractors to count awards to subtier subcontractors towards their goals in their subcontracting plan and thus a second set of goals is not required or needed.

76. Question: Specification section 01 40 00 – Quality Requirements – please clarify what, if any, quality control testing is to be provided directly by the Government.

In the specifications (section 230900 – 6) under ‘Products Furnished But Not Installed Under This Section’ it states that Control Valves will be furnished by controls contractor.

Answer: FCU on board controls should be factory installed and provided by the controls contractor. Preference is for controls to be sent to the manufacturer for factory install.

78. Question: Please provide a spec for the acoustic plaster ceilings shown in See You in Court 124 and Designed for Justice 122.

Answer: See specification section 092900 Gypsum Board section, 2.9B Acoustical Finish.

79. Question: Is fire protection/sprinkler going to be required inside of the Bally Building on Level 3?

82. Question: Some concerns have been raised about the air and water testing of the new sashes being installed into the existing frames. Spec Section 1.7.A.3 calls for specific tests that we have requested information on from a testing agency. Here is their response: ”After speaking to my laboratory, there is no way to lab test these windows without the frame. If they are asking for field testing, they should mention ASTM E783 in lieu of E330 and E1105 in lieu of E331. Perhaps they are just wanting the sash to have come from a window system that has been rated and tested to those standards? I would ask for more clarification. Either way, from my experience in the field and the lab’s opinion, those are some stringent requirements to meet. Those are lofty requirements for even modern windows with modern technology and typical aluminum. These windows are wood and don’t really stand a chance of passing these requirements. I would recommend field testing with a spray rack with minimal pressure (negative chamber) on the interior or do a spray nozzle test at a low pressure. Just know that these tests are only valid for new construction and that spray nozzle tests are not meant to be used on operable windows. It can be done, but it won’t be an “official” test. It will be more of a backcheck to make sure there aren’t any glaring issues. The bottom line is that there will always be chances of leaks when you leave the existing frame.” Please confirm the testing requirements for the new sashes.

Answer: Assume window will be field tested to ASTM E783 in lieu of E330 and E1105 in lieu of E331. Test procedure to be confirmed by historic treatment specialist hired by contractor (reference 080352, 3.1 Historic Treatment Specialist) and COR.
