Sheet 01-A802 Door/Window Notes 2, 3, 4 all refer to additional information on sheet A801.

Sheet A801 does not contain any information on the widows, doors, or door hardware. This happens on multiple Quarters' drawings and on the Museum drawings. Please clarify what sheet these notes are referring to.

These references to A801 are a clerical error and should reference either the A802 series sheets “Door and Window Schedules” or A803 series sheets “Door and Window Elevations”.

9/12/2025

Demo Floor Plan 01-AX101 & 01-AX201 both call for the basement windows to be removed and replaced. Sheet 01-A802 Demolition Window Schedule calls for Basement window 1.W0.01X to remain and requires Level 2 Wood Repair. Please confirm that sheet 01-A802 is accurate, and the demo plans are NOT accurate.

Confirming the sheet 01-A802 prevails.

9/12/2025

Sheet 01-A802 Window Schedule calls for sheet 01-A604 for window head, window sill, and window jamb details. The plan set does not contain a sheet 01-A604. Please confirm that this refers to sheet 01-A605, and that sheet 01-A604 does not exist.

Confirming that sheet 01-A605 prevails.

9/12/2025

Sheet 13-EX101 calls for the existing electrical devices in rooms Office 13.006, 13.008, 13.009, 13.011, and new outlets to be installed on sheet 13-E101 at different locations. The walls in this area have drywall that is above 1% ACM. The Hazardous Materials Report and other provided documents are unclear as to whether all ACM drywall exceeding 1% is supposed to be abated or if the Contractor is only required to abate the drywall at electrical devices and associated electrical rough-in.

ACM abatement shall occur only at areas directly associated with Electrical Scope. In certain rooms/locations this may be very localized (single digit square-footages), in other rooms/locations there may be enough Electrical scope to warrant abatement at an entire wall/walls (or similar).

9/12/2025

Are the new site electrical services supposed to be priced in CLINS 5? Correct

9/12/2025

Sheet 01-A101 Floor Plan Legend depicts the wall types for the existing walls to have a diagonal hatching. The new wood walls are solid. The floor plan indicates that all the walls are new wood walls. Please confirm that all the walls are existing and not new wood walls.

This happens on all Quarter and Museum drawings.

Correct – and thank you for bringing this graphic discrepancy to our attention. Thicker walls are existing sandstone construction. Interior “thin” walls are wood framed. NEW wood walls are indicated within A101 (and similar) series drawings via a darker grey shading relative to existing walls.

9/12/2025

Reference Question Response

Sheet 04-A201 Detail 4 South Elevation Note 18 says “All Vigas UON”. Elevation 2 North Elevation, same sheet, note 18 does not have UON after it, and is clearly pointing to 3 of the 7 vigas on this elevation. Keynote 18 same page calls for Level 3 wood repair. Does the “UON” only apply to South Elevation 4 and not North Elevation 2? This is consistent throughout other Quarters and the museum elevations.

This condition appears to be an attempt by the A/E to graphically simplify the drawings. All Vigas shown on both of the noted Elevations shall be understood to require “Level 3 Wood Repair” consistent with note 18.

Drawings within which similar instances occur shall follow the above guidance – i.e., assume “Level 3 Wood Repair”.

9/12/2025

Sheet 04-L101 CLIN 5 states “Re-Vegetate with Native See Typ.” CLIN 1 states “Overseed Typ. By Park,” The boxed text under 'Planting Notes' 5 states, 'Contractor will be responsible for soil preparation at areas of disturbance due to construction. Park will complete re-vegetation with in-kind, native seed and mulch...” The specifications do not contain a specification for seeding or landscaping. Please confirm that CLIN 5 and CLIN 1 seeding and revegetation will be performed by the Park. The contractor should not include revegetation or seeding in their pricing.

Correct. The park maintains strict levels of vegetation control and will perform re-seeding and/or re-vegetation at Contractor prepared areas.

9/12/2025

Addendum 1, 2, 3, 4, 5 all state the period of performance is 11/07/2025 to 5/11/2027.

Addendum 1 says to “Submit your schedule in Gantt Chart format; for evaluation purposes only assume a Notice to Proceed date of 12 Jan 2026”. The period of performance is 550 days after receiving the Notice to Proceed. 550 Calendar days from 1/12/2026 is 7/16/2027.

Should the schedule assume a NTP of 11/07/2025 and a completion date of 5/11/2027, or a Notice to Proceed of 1/12/2026 and a completion date of 7/16/2027?

The Gantt Chart format for evaluation purposes is going to start on January 12, 2026. The period of performance end date will change from 5/11/27 to 7/16/27 to match the 550 schedule after NTP. Dates may shift due to providing Div 1 requirements prior to NTP and actual award date. Dates posted as an answer to this question should only be concerned with providing the Gantt Chart for evaluation.

9/12/2025

Drawing 02-AX102 note 65 states “Remove (E) TPO Roof Membrane and Rigid Insulation.

Abate Hazardous Materials (ASSUMED)”. What are we assuming is hazardous, and what is the quantity?

The NPS is aware of multiple underlying roof “build-ups” below the existing TPO. No destructive testing nor destructive investigations were performed to determine the make-up and/or profile of said underlying “build-ups” – as a result, neither the exact hazardous materials nor quantities are known. It is presumed that underlying “build-ups” will include Asbestos Containing Materials (ACMs) consistent with historic practices (i.e., adhesives or other components).

Reference Question Response

Sheet 05-A101 calls for new wood walls. Please provide the wood wall framing details, i.e., the size of lumber, spacing of studs, and confirm that the wall finish is painted drywall in lieu of plaster. This happens in multiple buildings

•Refer to the following sheets to clarify the above •A601 series (Drawing 04) •A701 series please note there is a reference note at

Drawing 04 which directs to reference sheet A602, this reference should read A601 •S601 series •S602 series •framed partitions/walls shall conform to 06 10 00

“Rough Carpentry”, section 2.4 “Dimensional Lumber Framing” •stud spacing shall be 16” o.c. unless noted otherwise.

•new wall finishes at new framed locations shall conform to 09 21 16 “Gypsum Board Assemblies”

Question #25 asked if the Superintendent, SSHO, and QC Manager need to be three separate individuals. The NPS response was “yes”. On similar projects in the past, the Government has allowed the Quality Control Manager and Site Safety & Health Officer to be the same person. Will the NPS allow the Quality Control Manager to also serve as the SSHO for the Project?

Yes in the past on NPS projects there has been allowed Quality Control Manager and SSHO to be the same person. Yes NPS will consider the Quality Control Manager to also serve as the SSHO for the project.

Specification Section 01 30 40 paragraph 3.2.1.A Coordination with Utility Service Providers

– Electrical states “Contractor is responsible for establishing metering of new and temporary service”. Please clarify if the contractors are responsible for the cost of the new utility transformers and new utility meters? Alternatively, if the contractor is solely responsible for coordinating with Empire Electric for the transformer replacements and new meters, and any incurred costs will be covered by NPS/Empire Electric.

Confirming the first statement - the Construction Contractor is responsible for the cost of new Electric Service Distribution components including, but not limited to : transformers, splitters/junctions, meters, etc.
