FAR (48 CFR) 53.110

# Question: Answer Amendment No.:

1 Please clarify whether the Stable Street staging area shown on Sheet 00-G006 is available for the duration of the project.

Sheet 00-G006 is available for the duration of the project. This has been changed in the updated Sheet 00-G006.

2 Please clarify whether Building 83 is included in this project.

Any work associated with Building 83 his hereby deleted from this project. No work is required at Building 83.

3 Please clarify whether re-pointing of the exterior foundation walls is required all the way down to the top of the footings, as is stated on the Exterior Demolition Elevation sheets (Notes 7 and 8), or only as deep as the bottom of the perimeter gravel bed excavations, as is shown on the "perimeter gravel bed at (e) foundation details," like on 06-A801.

Re-point in accordance with "sequence of installation" shown on the detail you referenced.

Ignore the reference to the required depth of re-pointing on the Exterior Demolition Elevation sheets.

4 What structural upgrades are required at the walls and roofs of Buildings 2 and 3, as referenced in the Summary of Work for each of these buildings?

There are no wholesale upgrades required to the walls and roofs of these buildings. Ignore these references in the Summaries of Work and complete the work described in the remainder of the sheets associated with these buildings.

5 Can Site Superintendent function as the safety specialist?

No. No dual-hatting. 2

6 If possible to open the past performance period to at least 10 years

Yes. 2

7 Could we receive clarification regarding the paint preparation on the chimneys prior to repainting? Will they be fully abated and stripped to bare masonry prior to painting, or will they be prepared and encapsulated with new paint?

To clarify, existing paint at brick masonry chimneys will not be fully removed prior to repainting. The existing paint will be prepared and cleaned to receive new paint based on the “Degree of Surface Degradation” as defined in Section 09 03 91, 3.9 Surface-Preparation Schedule. Likely, there will be different surface preparations for different conditions. Contractors should bid on an “average” condition.

8 Spec 01 35 91, para 1.4 mentions that there will be a Historic Preservation Treatment Specialist. It also states that this person’s qualifications will meet 36 CFR Part 61.

However, there are no qualifications listed in 36 CFR Part

61. This CFR references “Procedures of State, Tribal, and Local Government Historic Preservation Programs.”

9 Is it a requirement to salvage metal roof tiles? 2 10 Spec 01 35 23, para 1.4 B calls for a Site Safety

Supervisor. Can this role also be filled by the same person as the Site Superintendent?

No. 2

11 Can one person serve as the SSHO, CQC and Superintendent? If not, please clarify which roles can be combined so that the total number of field managers on site can be determined.

No. 2

12 All around each house, there were numerous borrows seen for chipmunks and other animals. Please clarify who will be responsible for their removal. Once captured, did NPS want them released or handled by an exterminator?

The contractor is not responsible for capturing and disposing of rodents that are encountered during the performance of the site work.

Replace Specification 01 35 91 in the CDs with the 01 35 91 provided with this amendment. The new spec achieves the following:

1. Better defines the role of the Historic Preservation Treatment Specialist, and reduces the time-on-site requirement; and

2. Deletes the requirement to salvage metal roof tiles. They do not need to be salvaged.

13 01 57 23- Temp SWPP. Please clarify who is responsible for the NPDES permit fees.

Per Spec 01 31 00 (1.9)(A)(1), the Contractor is responsible for obtaining permits, which includes the payment of permit fees.

Revised Spec 01 31 00 (1.9)(C)(9) has been changed to read as follows: "Stormwater Pollution Prevention Permit - No permit anticipated, as improvements will occupy less than one acre of area."

An Under-an-Acre Pollution Prevention Plan (UPPP) as described in Spec 01 57 23 is anticipated.

14 What type of historic mortar analysis is required? E.g., Petrographic, X-Ray Diffraction, X-Ray Fluorescence, Scanning Electron Microscopy. How many mortar test samples are required per building? Please identify which parts of building the tests should be taken from? E.g., Chimney, foundation, etc.

Mortar analysis was completed for each building in August 2021. "Custom Mortar Matching Reports" by U.S. Heritage Group are included in Appendix C of the Project Specifications. Mortar mix designs listed in 04 03 00 of the Project Specifications are the same mortar mix designs proposed by U.S. Heritage Group. Attached is the Mortar Sample Log indicating where samples were taken. No additional mortar analysis is required.

15 Will archaeological and Cultural monitors be provided? The Park will be providing the archeological and cultural resources monitors.

16 What is the NTP date for planning purposes? Assume an NTP date of 03/03/25. 2 17 Who is responsible for snow removal in staging areas The contractor is responsible for snow removal within the staging areas.

18 Can the paint removal be done onsite? Location of paint removal is at the discretion of the contractor, however all federal, state and municipal guidelines are applicable, regardless of location.

19 ½” plywood added. Will now be created a 1/2” gap between the window and the trim. (see below sketch) How do we fill the void? We assume that NPS wants to salvage and reuse the existing trim and jamb. Hence, we will need to put in a filler piece. Will that be acceptable

The existing trim and jamb must be salvaged and reused to the greatest extent possible. However, existing sheathing (assumed to be true 1x) will be removed and replaced with 1/2" plywood sheathing and 1/4" furring strips. There is no net gain in sheathing thickness.

20 Spec 07 31-16-3 Field conditions 1.8A states not to install metal shingles when windchill <45degrees? This is unnecessarily restrictive and will limit the ability to have the work done. Can this be change to above 35 degrees ambient. I don’t understand the relevance of wind chill, either, unless the concern is that the workers will be too cold to do a good job.

For all components noted in 1.8.A, Contractor must comply with manufacturer's installation instructions.

21 Please clarify for the areas where we are to apply to paint to existing materials, are we to scrape down to a sound surface, or will we have to remove the existing paint 100% to the bare material.

Refer to 06 03 12 – 3.5 Paint Removal. Remove existing paint to bare substrate.

22 If there is a combination of scraping and full removal, please clarify which areas those would apply.

Refer to 06 03 12 – 3.5 Paint Removal. Remove existing paint to bare substrate.

23 Sheet 02-A901, why does only 4 openings show ‘exterior trim’ with level 1 repair? Why are the other windows shown as N/A? On the elevations, there does not seem to be any difference in these windows.

The exterior trim repair level for 2.N1.04, 2.N1.05, 2.N1.06, and 2.N3.01 should be “N/A.” The reason “N/A” is noted for all exterior trim, is because these windows are set into a stone masonry wall and do not have exterior trim.

24 Will electrical service be available at any of the staging areas shown on Sheet 00-G006?

There is an electric service available at the staging area located due east of Buildings 7 and 8, and northeast of Building 12.

25 Do you want all paint removed, down to bare wood, from all the window/door components regardless of needed repairs? Does paint need to be removed to bare wood only when necessary to perform repairs? Loose paint can be removed, and stable existing paint can be encapsulated.

Refer to Specification Sections 08 03 14 Historic Treatment of Wood Doors, and 08 03 52 Historic Treatment of Wood Windows, and 09 03 91 Historic Treatment of Plain Painting.

26 Will the contractor have to pay for gate entrance fees? No. The park will be providing access passes for all contractor personnel.

27 What is the retainment expectation for siding? See Specification Section 02 41 19 Selective Demolition for table showing assumed amount of salvageable siding.

28 Will wood shingles on building 2 and 3 be removed/ restored? Clarify scope of wood shingle siding throughout.

Wood shingles at Buildings 2 and 3 are to remain and will be repainted. Wood shingles at Buildings 4- 8, 10-12, and 30-33, will be removed and replaced in kind with new shingles. See Specification section 07 31 29-2, 2.1.A. Shingles and Shakes.

29 Is there matching stone available for use in masonry repairs?

Yes, replacement stone is available in the Yellowstone National Park stockpile. See Specification section 04 03 00-6 Historic Treatment For Masonry – 2.3.B.1. Feldspathic Sandstone:

Coordinate with Contracting Officer to obtain replacement material from Yellowstone National Park stockpile.

30 The siding on the dormers on Buildings 30-33 consists of shingles. Is there any scope associated with these shingles?

The intention is to remove the existing shingles and then replace them, per Detail 2 on Sheet 30-A803 (for example).

31 Buildings 30 to 33, Floor Plan Notes 9 and 10 say to salvage stair parts and skirt trim. Is that realistic?

See Specification Section 06 03 12 Historic Wood Repair. Subsection 3.8 Repair Procedures lists three levels of repair that correspond to Keynotes 22, 23 and 24 on the A100 Existing/Demo Exterior Elevation drawing sheets. If the removal of wood components causes damage beyond a Level 2 Repair, then a Level 3 wood repair (replacement in-kind) is acceptable.

32 "Repair spalling" is vague. Please list criteria where spalling needs to be repaired and methods of repair that will be acceptable.

For bidding purposes, spalling stone will be repaired with a masonry unit dutchman. See Specification section 04 03 00 - Historic Treatment of Masonry.

Subsection 3.7.B outlines the repair procedures for a dutchman installation.

33 "Repair stone delamination" is vague. Please list criteria where spalling needs to be repaired and methods of repair that will be acceptable.

For proposal submission purposes, delaminated stone will be repaired with a masonry unit dutchman. See Specification section 04 03 00 - Historic Treatment of Masonry. Subsection 3.7.B outlines the repair procedures for a dutchman installation.

34 Temporary facilities - What size storage container can we place on the site? How many storge containers can we bring on site?

Storage container size limited by extents of staging area.

35 Can we have a storage container on Officer’s Row if we have it blocked visually with temp fencing and screens?

Not prohibited by the contract, but YELL should be consulted. The Park requires at least one lane be provided for vehicle traffic to pass through the area.

36 Where can we place our work trailer? Can one be placed at Officer’s Row? Work trailer = job office?

Work trailer can be placed in area designated as staging location behind the Officer Row housing.

See Sheet 00-G006.

37 Are we permitted to use the public toilets in lieu of bringing in temp toilets?

No. The contractor must provide their own temporary toilet facilities, please reference Construction Specification 01 50 00 (Section 3.2(e).

38 Spec 06 03 12-6, para 3.3 E.1&2 states to remove landscape covering at the end of each work day. Can we use a breathable cover and pull it off only on the weekends.

No. 2

39 Spec 07-31-16-2 , para-1.6 mock ups , states to construct an 8’x8’ roofing mockup. Can that be 4’x4’ on the ground?

No. Mockup must be as denoted in the specification. 2

40 Please clarify that this a lead in construction project, not a lead abatement project.

Lead abatement is the responsibility of the contractor. Refer to 02 83 00 – Lead-Based Paint Stabilization, Component Removal, and Soil Removal. Refer to Appendix B: Hazardous Materials Inspection Report, Tetra Tech, Inc., August 2021.

41 Also do we need to itemize OH&P, PM/Superintendent/Labor rates, etc. on the price schedule?

Not on the price schedule but this information may be included in the narrative portion of the Volume II submission

42 Could spray insulation be used in the roof/ walls, to address concerns about construction time?

Use of spray foam insulation is not permitted unless approved by the Contracting Officer.

43 Are chimneys to be painted? Yes, only if they are currently painted. 2 44 Can we get a two-week extension for receipt of proposals?

The proposal due date is extended to November 4, 2024, at 2:00 p.m. Mountain time.

45 Which lanes do we use to enter the Park? If entering the Park through the Gardiner entrance gates, all contractors shall utilize the two gates reserved for visitors with the name of their company denoted on their truck for identification purposes.

At no time are contractors to utilize the employee-only gate.

46 What are the work hours for the project? Normal workhours are 7:00 a.m. to 6:30 p.m.

Monday through Friday. No noisy work before 8:00 a.m. Work on Saturdays, Sundays, Federal holidays or at night may not be performed without prior consent from the contracting officer.

47 Is signature required on the price schedule? No - signature is required on the SF 1442. 2 48 Do we need to itemize OH&P, PM/Superintendent/Labor rates, etc., on the price schedule?

No - this information should be included in hte narrative portion of Volume II submission.

49 Will all buildings be unoccupied at the start of the project?

No. The park cannot accommodate the displacement of all the residents of the buildings in this project simultaneously. Specification Section 01 11 00 (1.3), as modified by Proposal Amendment 2, identifies the limitations to working on multiple buildings at once, based on the Park’s ability to re-house displaced residents. The selected contractor will provide a project schedule per these limitations that, when reviewed and accepted by the Contracting Officer, will determine when the residents will have to move out to allow for construction. Contractors can assume that on the date their approved schedule says work will begin on a particular building that it will be unoccupied.

50 Please provide a detail for the rafter tail repairs Detail 3/02-A801 does not show any rafter tail repairs.

No wood repair work is anticipated on Building 2 or Building 3 rafter tails.

51 From the water table, how deep is the top of footing? Refer to question 3 and response posted w/solicitation amendment #2 on 08 oct 2024.

52 For bidding purposes, please clarify how much level 1,2 wood repair we should assume for the assumed quantities of clapboard to be restored.

REFER TO 06 03 12 for definition of Level 1/2/3 repair. Refer to Specification Section 02 41 19, 3.6 Wood Siding Salvage Table for estimated percentage of salvageable siding. No further definition or distinction between level of repairs shall be provided.

53 Per Detail 3/A801 What is the material/profile we are using for the soffit on all porches?

No repair/replacement of the underside of existing roof sheathing/boards is anticipated at this location.

54 BLDG #4-33, please confirm that the “Exterior Siding Types” are referring to shiplap siding, not exterior wood siding.

The term wood siding was used as a catch-all since there is more than one type of siding present at the subject buildings. For additional information, see the sheet legend titled “Exterior Siding Types,” on the A300 series exterior elevation sheets. Exterior siding types S-1 thru S-5 is shiplap. Exterior siding type S-6 is a vertical beadboard panel siding.

55 Per detail 3/30-S501 How many openings are required?

Is it for every Chimney? What does it mean “must be installed on different sides of the chimney with a minimum of 1’-0” vertical spacing.” Please provide elevations.

The opening in this detail is intended for installation of a new radon mitigation system through the chimney. At least one (1) opening is required in one

(1) chimney for each building. The note is to ensure that two (2) openings are not created in one wall of the chimney. If two openings are required (i.e. Bldg.

2), then a vertical distance between openings (in separate walls) is required. The intent is to not lose too much brick section in one area of chimney height. For additional information regarding the radon system, see detail 8/30-AA801.

56 Per Building 11 we are adding a (2) new slab on grade to the west porches, Is there any work on the foundation wall? Is there anything in that room? Can the existing slab be cut out and replaced without touching the foundation wall?

The existing foundation at the rear (west) porches of Building 11 is a pier and beam system. The presence of concrete pier bases is unknown. Exterior grade is high at the rear porch of Building 11 and the existing wood floor framing has been observed to be in contact with soil and in poor condition. A new slab on grade foundation will eliminate the issue of wood framing in contact with soil. The porches are used as utility/laundry rooms.

57 In BLDG. 14 drawings there is no details for the screen doors. Should we use the same detail that is in BLDG.

11?

Per Door/Window Note #2 or sheet A901, all existing screen doors are to be restored with new screen material. The level of wood repair is noted on the door schedules. Per Door/Window Note #3 of sheet A901, fabricate and install new screen and storm doors when noted on the door schedule. Only door 7B.101 at Bldg. 7 is to receive a new storm door per detail 10/07-A806.

58 Per sheet 30-A101, are we installing a new concrete foundation ledge or is it existing?

The concrete foundation ledge is existing. 3

59 Please confirm that the intent is to have the haunch slab edge sit on top of the Sono tube concrete footing per detail 3/31-S503.

Confirmed. The structural intent is for the vertical bar in the sonotube to extend into the thickened slab above.

60 Is the contractor only repointing the full interior foundation walls at Building 33? Please confirm there is no pointing needed in building 31, 32. Please show access point to get into the crawl space.

The drawing note on view 1/33-S101 “Repoint all interior stone that is accessible from crawlspace” was added in error. Access to all crawlspaces is noted on Foundation Plans.

61 Why are only selected buildings getting storm doors? See response to Question 57. 3

62 For all buildings with wood porches, is the contractor building new structural framing or are we reinstalling the existing structure framing?

Refer to structural plans for extent of structural framing being retained vs. replaced. For example, sheet 04-S201 notes “(E) Porch joists; Replace damaged joists as needed; Assume 50% replacement.” In some instances, existing roof porches may need to be shored while structural framing members below are being replaced.

63 For buildings #3-33 on sheet A901, if there is a “no” for new storm windows, is the contractor restoring the existing storm window?

Per Door/Window Note #6 on sheet A901, for Buildings 3-33, all existing storm windows will be removed (demolished) and new storm windows will be fabricated and installed. Note #6 should be supplemented with “unless noted “N” on the window schedule “New Storm Window” column.”

The “N” indicates the window will not receive a new storm window.

64 Due to the amount of work requested, and the limited amount of work available in the winter months, we are asking that the contract duration be extended to 1300 calendar days.

The period of performance remains unchanged. 3

65 Please confirm that the only interior foundation wall repointing is where a bolded line is shown and noted.

Correct. See response to question 68. 3

66 The prevailing wages included in the specifications states it is for “Montana”. This project is located in Wyoming.

Please confirm that the prevailing wages in the RFP is correct.

The prevailing wage rate shall be in accordance with General Decision Number: WY20240013 dated 10/18/2024. A copy is attached to this amendment.

67 Please provide the type of insulation that is existing in the perimeter walls of Bldgs 4-33.

The perimeter wall insulation was not visible during site investigations, however, where siding was damaged or missing, exterior wall insulation was observed to be pink fiberglass batt insulation. The same insulation was also observed in select roof/attic cavities.

68 05-S101- please confirm the bolded lines in the basement are areas to be pointed. Otherwise, there are no notes indicating any pointing of the interior foundations.

Correct, bolded lines with the following note are areas to be pointed: “Indicates approximate extent of (E) stone wall to be repointed. Repointing requirements per architectural drawings.” See snippet below for occurrence of bold line and note at Building 5. See Demolition Exterior Elevations for extent of interior foundation pointing.

Keynote #188: Extents of structural repairs to masonry foundation. Use the mortar joint as noted on this sheet. RE: Structural foundation plans for additional information.

Correction to Keynote #188: Extents of structural repairs to masonry foundation. At exterior of wall, use the mortar joint as noted on this sheet. At the interior of wall, use joint Type 2C, Overgrout as shown on detail 6/05-A801. RE: Structural foundation plans for additional information.

Demolition Exterior Elevation Notes #7 and #8:

Repoint exterior of all stone foundation walls from top of footing to… Correction to Demolition Exterior Elevation Notes #7 and #8: Repoint exterior of all stone foundation walls from lowest point of excavation as noted on civil drawings to….

69 Bldg 2,3 : The 2 front porches require a new concrete slab. The only way to do this is to saw cut out the existing slab, while leaving the rest of the porch structure in place. Ie. Piers, retaining walls.

This approach is structurally acceptable. With this approach, the new concrete slab will tie into the existing surrounding concrete foundation elements to remain. This can be accomplished by epoxy doweling slab rebar into the remaining concrete prior to pouring the new slab.

70 Please confirm how we are to 'flip' the stone treads with the porch columns sitting on top? Can we cut the stone treads at the face of the columns so that we do not have to disturb the columns? Can we grind the stone tread to account for the new slope?

The top tread at Building 2 front porches appears to be a separate stone. See photos.

71 30-A501 (typical for Bldg 30-33) Note 150 states to reinstall repaired components. Can you provide the expected level of finish and a chart indicating the % of wood that will need to be restored versus new.

Refer to Demolition Plans and Demolition Elevations for level of repair.

72 Why does Bldg #32,33 have a slab on grade on the rear porch, but Bldg 30,31 do not have such slab? Is that correct?

Building 30 will have a sonotube foundation with wood-framed floor. Buildings 31 thru 33 will have a slab on grade foundation with pressure treated framing members. Exterior grade is high at the rear porches of Buildings 31 thru 33 and the existing wood floor framing has been observed to be in contact with soil and in poor condition. A new slab on grade foundation will eliminate the issue of wood framing in contact with soil.

73 Is there any information available (manufacturer, date of installation, etc.) for the tile roofing?

To be answered in a future amendment. NA

74 Typical for bldg. #4-33, it calls for Level 2 repair of the clapboard siding. We do not believe that attempting a dutchman, splice will be feasible, nor aesthetically acceptable upon completion. We recommend only using epoxy or replacing sections with new clapboard. Please confirm if this is acceptable.

Product substitutions shall be submitted through the submittal approval process denoted in the contract documents after contract award. The proposal submission shall be submitted in accordance with the solicitation requirements.

NA

75 Please confirm if NPS will have a representative on site to make the determination as to where the clapboard is to be repaired and if a level 2 repair will be adequate.

To be answered in a future amendment. NA

76 04-A803 (typical bldg. #4-33) , detail 7,8,9- when we restore the clapboard, what is the maximum number of splice joints over 10’ length, we have to consider, before we can replace the entire board?

To be answered in a future amendment. NA

77 Can we assume that we must span at least 2 wall studs for the minimum length of clapboard to be replaced?

To be answered in a future amendment. NA

78 Storm windows- Does NPS only want the top mounted storm with the push out where it calls it out in the notes of the window schedule (sheet A901)?

- Where it does not call out “provide top hung storm,” are we to only replicate the storm?

- Or, is every DBL Hung needing a new storm getting a top hung storm?

To be answered in a future amendment. NA

79 In Bldg. 32 (and most likely in Bldg. 31-33), there is existing spray foam on the interior of the foundation walls. Should the crawlspace radon barrier be placed over the spray foam?

To be answered in a future amendment. NA

80 In Add#1 , rebid #2, included a chart called “basement and crawlspace stone repointing locations.” Is this chart to be ignored as part of Bid #3?

To be answered in a future amendment. NA

81 Will the Superintendent be permitted to work with their hands while at the job?

No NA

82 For the clapboard that is salvaged and restored, will we have the option to install where needed per elevation?

Or, will it have to be installed exactly in the same location where it was removed?

To be answered in a future amendment. NA

83 Should all of the new clapboard be combined into one location, or installed where the damaged clapboard was replaced?

To be answered in a future amendment. NA

84 Please provide a drawing showing the metal shingle dimensions so that we can get accurate pricing.

To be answered in a future amendment. NA

85 Please confirm Bldg #8 is the only building that gets snow guards.

To be answered in a future amendment. NA

86 Please clarify if we can redistribute the excavated soils for the gravel bed on site around the building for site restoration. This assumes the top lead layer has been properly disposed of.

To be answered in a future amendment. NA

87 Please confirm if the options 1-15 will be taken in order.

Alternatively, will the options be taken in order per the phasing plan? Or, will NPS have the ability to take options in a random sequence.

The options will be exercised in any order that the Government determines appropriate.

Amd. 3

88 Will NPS award option during the course of the contract? Please refer to Solicitation Clause "Special Requirement: Option for Additonal Services - Separately Priced Line Items - The Government may require the delivery of the numbered line items identified in the Schedule as option items at the price stated in the Schedule. The CO may unilaterally exercise the option by written notice to the Contractor within 90-days after contract award.

Performance of added line-item tasks shall be at the price negotiated in the contract Schedule."

Amd. 3

89 When we create our CPM schedule, do we follow the phasing plan or the options schedule?

Please follow the phasing plan identified in the solicitation documents.
